LUBRICATION & MAINTENANCE

Using the chart below, determine an appropriate lubricant viscosity. Use only EP (extreme pressure) or API GL-5 designated lubricants.

Change the lubricant after the first 50 hours of operation and at 500 hour intervals thereafter. The gear drive should be partially disassembled to inspect gears and bearings at 1000 hour intervals.

Unit Teardown

1) Scribe a diagonal line across the outside of the unit from the cover (2) to the base (1) before disassembly to aid in the proper positioning of pieces during reassembly.

Caution: Since the shaft is no longer positively retained, care should be taken to avoid injury. Care should also be taken not to damage it while pressing through base.

2) Remove drain plugs (42) and drain oil from unit. The oil will drain out more quickly and completely if warm.

Press output shaft out bottom of base by applying a load to internal end of spindle (3) until it passes through inner spindle bearing cone (25).

3) Remove the 20 3/4-10 capscrews (43) and 3) A gear puller may be used to remove the outer bearing lockwashers (46) retaining the cover (2).

cone (23) from the spindle (3). If reusing old bearing cone, do not pull on or damage roller cage.

4) Remove the cover (2), thrust washer(s)/bearing(s) (30,31,32), and input gear (17). Inspect o-ring (33); discard if damaged or deformed.

Note: Press bearing cone onto output spindle by pressing on inner race only. DO NOT press on roller cage, as it may damage the bearing assembly.

5) Lift the planet carrier assembly out of the unit .

6) Remove ring gear(s)/spacer (8/10pri, 7sec) and subsequent

Inspect gear to gear and gear to base Oring(s) (33); as before, discard if damaged or deformed. brass drift and utilizing the bearing knock-out notches in the base (1)

7) The unit is now disassembled into groups of parts.

The area(s) requiring service should be identified by thorough inspection of the individual components after they have been cleaned and dried.

Base Reassembly

1) Clean all foreign material from magnetic oil plugs located

In base (1).

Carrier Assembly Teardown

Rotate planet gears (12/13 pri;11 sec) to check for abnormal noise or roughness in bearings. If further inspection or replacement is required, proceed as follows.

1) Primary: Drive roll pins (39) completely into the planet shafts

(19). Secondary: Remove planet shaft retaining rings (36), spacers (21) and preload shims (20)

2) Place base exterior side up on work table.

3) Apply a layer of lithium or general purpose bearing grease to the roller contact surface of outer bearing cup (24).

4) Press outer bearing cone (23) onto the spindle (3) until it seats against the shoulder.

2) Slide planet shafts (19 pri/18 sec) out of carrier.

sec) and bearings (29 pri;27/28 sec) from carrier (6).

4) Inspect the planet gear (12/13 pri; 11 sec), bearing bore and planet shaft (19 pri/18 sec) and bearings (29 pri; 27/28 sec).

Check for spalling, bruising or other damage and replace components as necessary.

5) Wipe the face of each half of the metal face seal (49) using a lint-free wipe. No particles of any kind are permissible on the sealing surfaces. (Even a hair is sufficient to hold the seal surfaces apart and cause a leak.) Apply a thin film of oil on the entire seal face of one or both seals using a clean finger or lint-free applicator. Oil must not contact any surfaces other than the sealing faces. (See Pages 6-8 for seal inspection and service procedures.)

5) Primary only: Remove roll pins (39) from planet shafts (19) using a 1/4 inch pin punch.

6) Place the spindle (3) with the outer bearing cone into the base.

Carrier Reassembly

1) Primary: Planet shafts (19) should be installed with chamfered end of 1/4 inch roll pin hole towards outside diameter of carrier (6); this will ease alignment of holes while inserting roll pins (39). Secondary: Planet shafts must be installed aligning the slot in the large end of the shaft with the roll pin protruding into the shaft bore.

7) Flip shaft/base assembly, and apply lithium or general purpose bearing grease to roller contact surface of the inner cup (26), then press inner bearing cone (25) onto shaft until it seats against inner bearing cup.

2) Primary: Drive roll pin (39) into the carrier hole and into planet shaft to retain parts. Secondary: Install the first planet washer

(21) to the small end of the planet shaft, the appropriate number of preload shims (20) and then the second planet washer

(21) and retaining ring (36) Repeat for remaining planet gears.

8) Proper spindle bearing preload will result in a rolling torque which varies between 200 to 300 in-lb. The bearing preload should be tailored to your application; a low-speed application may require a high pre-load, while high-speed applications usually benefit from low pre-load. Adding shims (15) will increase the pre-load on the bearing set. Determine your pre-load requirement and install shims to obtain this preload.

Base Subassembly Teardown

1) Remove the output shaft lock ring (14) using a heel bar or puller; if using a heel bar, be sure not to pry against the cage of the inner spindle bearing (25). Remove the split ring segments (35) and shims (15).

9) Install the Load-N-Lock™ halves (35) over the shims and into the corresponding spindle groove. Then, install the lock ring (14) over the Load-n-Lock halves (35B).

All subassembly service or repairs should be complete at this time. Continue to Unit Assembly to com-

2) Install carrier retaining plate (47) & secure using provided 3/8-

24 Flathead capscrews (48). If using thread locking compound to assist in screw retention, apply only a small amount to internal threads. Use of excess thread lock may cause screws to be irremovable once compound has cured.

8) Install and torque the 20 3/4-10 hex-head capscrews (43) with lockwashers (46). The torque for the cap-screws: 380 ft-lb dry, 280 ft-lb if the fasteners are lubricated.

9) Using a splined shaft to drive the input gear (17) ensure that the unit spins freely.

10) Fill the unit to the proper level, as specified, with recommended gear oil (refer to chart, page 3) after unit is sealed with brake and/or motor.

The gearbox is now ready to use.The gear drive is now ready to use.

Caution: Hold ring gear by outside diameter or use lifting device to prevent injury.

4) Align the gear teeth of secondary ring gear (7) with the gear teeth of the planet gears (11) and place ring gear on base aligning mounting holes of ring gear with holes in base. Use the scribed line made during disassembly for reference. With carrier in place, install secondary sun gear.

Simple Planetary Primary, for compound primary skip to step 5C ring in place), align mounting holes of ring gear with holes in base using the scribed line made during disassembly for reference. Install the primary carrier assembly aligning gear teeth of ring gear with those of the planet gears and place on base. Install the input gear (17).

Inspection of Worn Seals

Seals wear in an axial, rather than radial, direction (as depicted in Figure Y). The total thickness of the flange is usable wear material on the formed seal rings and good seal performance can generally be expected until the flange is completely worn away.

Remaining service life can be estimated by measuring the ring flange thickness, and using the chart below. Minimum flange thickness required for reusability is 0.05” (1.27 mm).

Measure Flange

Thickness Here

Housing Preparation

The housing components (3, 4) that contact the rubber toric rings must be free from foreign material (oil, grease, dirt, metal chips dust or lint particles, etc.) before installing the seal. This should be done with a lint-free wipe and a non-petroleum based solvent.

1) Remove any foreign material from the rubber torics (2), ramps

(7) and lips (8) of both seal rings. This should also be done with a lint-free wipe and non-petroleum based solvent.

2) Dry with a clean wipe.

3) Place the rubber toric (2) on the metal seal ring (6) at the bottom of the seal ring ramp (7) and against the retaining lip (8)

(see illustration on previous page). Make sure the rubber toric is straight on the seal ring and not twisted. Be careful not to nick or cut the torics during this assembly, as this can cause leaks.

4) Put the installation tool (9) onto the metal seal ring (6) and rubber toric (2). Lightly dampen the lower half of the rubber toric with the appropriate assembly lubricant. Techniques to dampen the toric include wiping with a lint-free towel, lubricating using a clean foam brush, or dipping into a container lined with towels saturated in the assembly lubricant (as shown).

The measured parameter used to check the remaining seal life is flange thickness, at the outer edge (once any wear lip is removed).

The measurement must be made carefully because the shoulder is only 0.06” (1.52 mm) from the edge of the flange.

Estimates of expected seal life are difficult, because there are many differences in machine applications, job conditions, maintenance and other factors that affect seal service life.

Mishandling Of Seals

Mishandling of seals during assembly can cause immediate leaks or premature failure. Failure can occur due to cutting or tearing of the elastomeric load ring, breakage of the sealing ring, contamination of the sealing face with dirt or lint, etc. When assembling metal face seals, please carefully observe assembly instructions.

Model 600 Spindle Drive service manual, SM600LS2-AG Page 7

Eskridge, Inc. Olathe, Ks. 913-782-1238 www.eskridgeinc.com

Installation Process

1) With the lower half of the rubber toric still wet, use the installation tool (9) to position the seal ring (1) and the rubber toric (2) squarely against the housing retainer lip (3)

(as shown).

2) For smaller diameter seals, use sudden and even pressure to push the rubber toric under the retaining lip of the housing.

For larger diameter seals, which will not press in with sudden and even pressure, it is acceptable to work the toric past the retaining lip by starting on one side and tapping the opposite side of the installation tool with a rubber mallet until it is engaged past the retaining lip of the housing.

3) Check the assembled height (A) (see below) in at least four places, 90º apart, using either a caliper, tool makers’ ruler or any other calibrated measuring device. The difference in height around the ring must not be more than 0.04” (1 mm). If small adjustments are necessary, do not push or pull directly on the seal ring. Use the installation tool (9) to push down and your fingers to pull up uniformly on the rubber toric and seal ring.

NOTE: The rubber toric can twist if it is not completely wet during installation or if there are burrs or fins on the retaining lip of the housing. Twists, misalignments and bulges of the toric will result in seal failure. If correct installation is not apparent, remove seal from the housing and repeat the process.

The rubber toric must never slip on the ramps of either the seal ring or the housing. To prevent slippage, allow adequate evaporation time for the lubricant before proceeding with further assembly. Once correctly in place, the rubber toric must roll on the ramp only.

4) Wipe each seal ring face (6) using a lint-free wipe. No particles of any kind are permissible on the sealing surfaces.

(Even a hair is sufficient to hold the seal surfaces apart and cause a leak.)

5) Apply a thin film of oil on the entire seal face (6) of one or both seals using a clean finger or lint-free applicator. Oil must not contact surfaces other than the sealing faces.

NOTE: Mishandling of seals during assembly can cause immediate leaks or premature failure. Failure can occur due to curing or tearing of the elastromeric load ring, breakage of the sealing ring, contamination of the sealing face with dirt or lint, etc. When assembling metal face seals, please carefully observe assembly instructions.

Final Assembly

While completing the final assembly of the unit, make sure that both housings are in correct alignment and are concentric.

Slowly bring the two housings together. High impact can scratch or break the seal components.

If the rubber toric slips at any location, it will twist, causing the seal rings to cock. Any wobbling motion of the seal is an indication of cocked seals and can cause dirt to enter by pumping mud past the torics.
