Before attempting welding repairs on the asphalt tank, make sure that the tank is thoroughly clean. Use Detrox process, or equal. Compressed air used for cleaning purposes will not exceed 36 PSI. Use only with effective chip guarding and personal protective equipment (goggles/shield, gloves, etc.).

PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) 2-6. Organizational Preventive Maintenance Checks and Services. To insure that the distributor is ready for operation at all times, it must be inspected systematically so that defects may be discovered and corrected before they result in serious damage or failure. Table 2-1 contains a tabulated listing of preventive maintenance checks and services to be performed by organizational maintenance personnel. All deficiencies and shortcomings will be recorded as well as the corrective action taken on DA Form 2404 at the earliest possible opportunity. a. The item numbers of Table 2-1 indicate the sequence of the PMCS. Perform at the intervals shown below: (1) Do your (Q) PREVENTIVE MAINTENANCE once each 3 months. (2) Do your (S) PREVENTIVE MAINTENANCE twice a year, or each 6 months. (3) Do your (A) PREVENTIVE MAINTENANCE once each year. (4) Do your (B) PREVENTIVE MAINTENANCE once each two years. (5) Do your (H) PREVENTIVE MAINTENANCE at the hour interval listed. (6) Do your (MI) PREVENTIVE MAINTENANCE when the mileage of the vehicle reaches the amount listed. If something doesn’t work, troubleshoot it with the instructions in this manual or notify b. your supervisor. Always do your preventive maintenance in the same order, so it gets to be a habit. Once C. you’ve had some practice you’ll spot anything wrong in a hurry. d. If anything looks wrong and you can’t fix it, write it down on your DA Form 2404. If you find something seriously wrong, report it to direct support as soon as possible. Dry cleaning solvent SD-2, used to clean parts is potentially dangerous to personnel and property. Do not use near open flame or excessive heat. Flash point of solvent is 1380 F. (1) Keep it clean: Dirt, grease, oil, and debris only get in the way and may cover up a serious problem Clean as you work and as needed. Use dry cleaning solvent (SD-2) to clean metal surfaces. Use soap and water when you clean rubber or plastic material. (2) Bolts, nuts, and screws: Check that they are not loose, missing, bent, or broken. You can’t try them all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads. Tighten any that you find loose. (3) Welds: Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad weld, report it to direct support. 2-2 TM 5-3895-371-24 & P (4) Electric wires and connectors: Look for cracked or broken insulation, bare wires, and loose or broken connectors. Tighten loose connections and make sure the wires are in good condition. (5) Hoses and fluid lines: Look for wear, damage, and leaks. Make sure clamps and fittings are tight. Wet spots show leaks, of course, but a stain around a fitting or connector can mean a leak. If a leak comes from a loose fitting or connector, tighten it. If something is broken or worn out, either correct it or report it to direct support (refer to MAC chart). e. It is necessary for you to know how fluid leaks affect the status of your equipment. The following are definitions of the types/classes of leakage you need to know to be able to determine the status of your equipment. Learn and be familiar with them and REMEMBER - When in doubt, notify your supervisor! Leakage definitions for Organization PMCS CLASS I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops. CLASS II Leakage of fluid great enough to form drops but not enough to cause drops to drip from the item being checked/inspected. CLASS I I I Leakage of fluid great enough to form drops that fall from the item being checked/ inspected. 2-3 TM 53895-371-24 & P Table 2-1.

Figure 3-27. Removing Shaft Seal Retainer. 3-25 TM 5-3895-371-24 & P (18) Inspect the inner race of ball bearing (13, fig. 3-4) for galling or roughness If no damage is apparent and if no damage was observed when the outer race was inspected, then it is not necessary to remove the inner race from the shaft. If damage to either the inner or outer race is observed, both must be replaced. The inner and outer races are serviceable as a matched set only. Remove retainer ring (12). Slip inner face from pump shaft (53). i. Assemble Hydraulic Pump. (1) Inspect pump shaft (53, fig. 3-4) for excess wear or damage. If either spline shows damage or if bearing journal or seal surface shows galling, scoring or heat discoloration, replace shaft. (2) If inner and outer races of ball bearing (13) are not damaged or won, assemble inner race on shaft (53) with retaining ring (12) using snapring pliers. If either inner or outer race is damaged, replace bearing as a set only. Install new inner race as described above. (3) If previously removed, install inner retainer ring (47). Inspect old ball bearing. If galled or damaged, press new ball bearing (48) on pump shaft. Ball bearing (48) should seat against inner retainer ring (47). Be sure not to deform inner retainer ring by forcing ball bearing (48) against it. If deformed, back ball bearing (48) off and reseat. Care should be taken to support inner race of ball bearing (48) in arbor press while pressing in pump shaft (53). Heating the ball bearing in hot oil will aid in a smooth bearing installation. Install outer retaining ring (47). 3-26 TM 5-3895-371-24 & P (4) Install pump shaft (53, fig. 3-4), ball bearing (48), retaining ring (47), retaining ring (12) and inner race of bearing (13) through the front face of the mounting flange (55). (See fig. 3-28). The ball bearing (48, fig. 3-4) should fit snugly in the mounting flange (55). If ball bearing (48) doesn’t seat easily, heat mounting flange (55) in hot oil and seat ball bearing in proper position. Do not drive the ball bearing (48) into place. Do not use the shaft seal assembly (51) to force bearing into seat. Check ball bearing (48) for free running by rotating pump shaft (53). (5) Press a new shaft seal (50) into the seal assembly (51) using an arbor press with a 2-1/2 in. plug and loctite sealant. Fill cavity between oil lip and wiper lip approximately 3/4 full with multipurpose grease. Install new O-ring (49) in mounting flange (55). To prevent possible cuts or abrasions, the O-ring (49) should be lightly coated with a multi-purpose grease. Wrap shim stock or other thin material around shaft spline and carefully slide seal assembly (51) over pump shaft (53). Figure 3-28. Installing Pump Shaft Assembly. 3-27 TM 5-3895-371-24 & P (6) Replace O-ring (49) on mounting flange (55), line up bolt holes, and secure assembly (51) to mounting flange (55) with four capscrews (52) and lockwashers (2).

It is extremely important that the bearing be started straight into the born. If the bearing cocks at any time during assembly, remove and discard the bearing Support the cam lug on the under side to avoid bending the lug. Outer face of trunnion bearing (40) should be pressed flush with outer face of cam assembly (42). Figure 3-29. Installing Shaft Seal Retainer. 3-28 TM 5-3895-371-24 & P (8) Examine wear plate (34, fig. 34). Circular patterns burnished on the surface of the cam plate am normal. If circular patterns on the wear plate are extensive and can be felt with the fingernail, or if angular scratches are evident, the plate must be discarded. (Refer to fig. 3-30). (9) Match up dowel pin (33, fig. 3-4) in cam assembly (42) with dowel pin hole in wear plate (34), and seat wear plate (34) in cam assembly (42). (Refer to fig. 3-31.) Check proper seating by pushing down on first one edge and then the opposite edge of the wear plate in a rocking motion. If any looseness is felt, remove cam plate and completely clean and compressed air dry both the cam assembly (42, fig. 3-4) and wear plate (34) to remove any foreign particles from beneath wear plate. Reposition wear plate in cam assembly (42) and repeat above procedure. If wear plate (34) refuses to seat properly, check plate for flatness and replace if necessary. Figure 3-30. Cam ‘Reaction to Wear” Plate. Figure 3-31. Installing Cam Wear Plate. 3-29 TM 5-3895-371-24 & P (10) With a push-pull motion, check for free play between bronze shoe, part of piston assembly (31) and steel piston body. If any play can be felt, the piston must be discarded. Inspect bronze piston shoes (31). During normal service, a dulling of the running surface is to be expected. If large scratches that can be felt with a fingernail are present (fig. 3-32) make several short passes over 500 grit emery paper on a lap surface. On the last few passes, place five to six sheets of emery paper as a cushion under the top sheet to obtain the proper edge sharpness. Check the reworked piston assembly (31, fig. 34) with tolerance limits in figure 3-33. If piston shoe does not fall within tolerance limits, discard reworked piston and replace. Check as follows: (a) Check piston shoe for iron or steel particles imbedded in the running surface. If present, discard the piston. (b) Often, large scratches on the piston shoe running surface will “heal over” if placed back in service. It is recommended, however, that all piston shoes with badly scratched running surfaces be either reworked within tolerance limits or replaced. Figure 3-32. Inspecting Piston Shoe. Figure 3-33. Piston Shoe Rework Tolerance. 3-30 TM 5-3895-371-24 & P NOTE Hydraulic pumps may be encountered with either two groove or three groove pistons. (Refer to fig. 3-34.)

Observe the following: (a) Examine the cylinder block assembly (23, fig. 3-60) for excessive wear or damage. Cylinder bores that exhibit only slight burnishing of the bronze liners are acceptable for reuse. If the bores exhibit galling or any other irregularity in the running surface that can be felt, the cylinder block assembly must be discarded. If there is evidence that the bronze liners have begun to pull out of the steel block, the cylinder block assembly must also be discarded. (b) Examine the upper running face of the cylinder block assembly (23). (Refer to fig. 3-69.) Circular wear patterns or phonographing that cannot be felt with the fingernail are normal. TA 075941 Figure 3-68. Removing Cylinder Block. 3-60 TM 5-3895-371-24 & P TA 075942 Figure 3-69. Inspecting Cylinder Block. (c) If the cylinder block assembly is acceptable for reuse in all other respects, several passes of the block over 500 grit emery paper on a lap table, is recommended to put the block face in a like-new condition. If circular wear patterns can be felt with the fingernail, grind the running face as necessary to remove the wear pattern keeping the face parallel to the original face. Lap the reworked face on 500 grit emery as described above to remove the mat finish. Clean the block thoroughly in a commercial degreaser such as trichloroethylene and blow dry with compressed air. Check tolerance of refinished block as outlined in figure 3-70. If reworked block does not meet the tolerances, discard block. TA 075943 Figure 3-70. Cylinder Block Rework Specifications. 3-61 TM 5-3895-371-24&P Be careful when removing block spring (25, fig. 3-60). It is under considerable tension.

General. a. This section provides a general explanation of all maintenance and repair functions authorized at various maintenance levels. b. The Maintenance Allocation Chart (MAC) in section II designates overall responsibility for the performance of maintenance functions on the identified end item or component. The implementation of the maintenance functions upon the end item or component will be consistent with the assigned maintenance functions. c. Section III lists the special tools and test equipment required for each maintenance function, as referenced from section II. B-2. Maintenance Functions. a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical and/or electrical characteristics with established standards. b. Test. To verify serviceability and detect incipient failure by measuring the mechanical or electrical characteristics of an item and comparing those characteristics with prescribed standards.’ C. Service. Operations required periodically to keep an item in proper operating condition, i.e., to clean (decontaminate), preserve, drain, paint, or replenish fuel, lubricants, hydraulic fluids, or compressed air supplies. d. Adjust. To maintain, within prescribed limits, bringing into proper or exact position, or by setting the operating characteristics to specified parameters. e. Aline. To adjust specified variable elements of an item to bring about optimum or desired performance. f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test measuring and diagnostic equipment used in precision measurement. Consists of comparisons of two instruments, one of which is a certified standard of known accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being-compared. lnstall. The act of emplacing, seating, or fixing into position an item, part, or module (component or assembly) in a manner to allow the proper functioning of an equipment or system. h. Replace. The act of substituting a serviceable like type part, subassembly, or module (component or assembly) for an unserviceable counterpart i. Repair. The application of maintenance services or other maintenance actions to restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module (component or assembly), end item, or system. B-1 TM 5-3895-371-24 & P Overhaul. That maintenance effort (services/actions) necessary to restore an item to a comj. pletely serviceable/operational condition, as prescribed by maintenance standards (i.e., DMWR) in appropriate technical publications. Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not normally return an item to Iike-new condition. k. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable equipment to a like-new condition in accordance with original manufacturing standards. Rebuild is the highest degree of materiel maintenance applied to Army equipment. The rebuild operation includes the act of returning to zero those age measurements (hours/miles, etc.) considered in classifying Army equipments/components. B-3. Explanation of Columns in the MAC, Section II. a. Column 1, Group Number. Column 1 lists group numbers, the purpose of which is to identify components, assemblies, subassemblies, and modules with the next higher assembly. b. Column 2, Component/Assembly. Column 2 contains the names of components, assemblies, subassemblies, and modules for which maintenance is authorized. Column 3, Maintenance Functions. Column 3 lists the functions to be performed on the item listed in column 2. (For detailed explanation of these functions, see para B-2.) d. Column 4, Maintenance Level. Column 4 specifies, by the listing of a “work time” figure in the appropriate subcolumn (the lowest level of maintenance authorized to perform the function listed in column 3. This figure represents the active time required to perform the maintenance function at the indicated level of maintenance. If the number or complexity of the tasks within the listed maintenance function vary at different maintenance levels, appropriate “work time” figures will be shown for each level. The number of man hours specified by the “work time” figure represents the average time required to restore an item (assembly, subassembly, component, module, end item, or system) to a serviceable condition under typical field operating conditions. This time includes preparation time, troubleshooting time, and quality assurance/quality control time in addition to the time required to perform the specific tasks identified for the maintenance functions authorized in the maintenance allocation chart.

Was brought to you by me: Liberated Manuals -- free army and government manuals Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends? I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on. I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines: <A HREF=http://www.liberatedmanuals.com/>Free Military and Government Manuals</A> – Sincerely Igor Chudov http://igor.chudov.com/ – Chicago Machinery Movers
