Unit Disassembly Procedure
There are two types of model D50 units: single planetaries without a primary carrier and double planetaries with a primary planet carrier. Steps with an asterisk (*) apply only to the double planetary model.
*Primary Planet
Carrier Subassembly
All parts should be inspected as they are removed from unit.
1) Scribe across base (1) , ring gear (2) and cover/ bail assembly
(3) joints on outside of gearbox to assure proper orientation of oil fill and drain plugs, motor mounting, etc., as the unit is reassembled.
2) Remove hydraulic motor (41) from auger drive. Drain oil.
3) Remove the twelve 7/16 x 4-1/2” socket head cap screws
(27) and 7/16 lockwashers (31) , which retain cover/bail assembly (3) and ring gear (2) to base (1) .
4) Lift cover / bail assembly and input thrust washer
(3)
(26)
off of unit; remove input gear
.
(12)
Disassembly
Rotate primary planet gears (8) to check for any abnormal noises or roughness in the primary planet bearings (25) . At the same time, inspect planet gears for any damage or worn teeth. If replacement or further inspection is required, proceed as follows.
*5) Primary planetary assembly is now ready for removal
(includes items 6,8,14,17,25 & 30). Secondary sun gear
(11) is splined to primary carrier (6) and may come out when removing planetary assembly; if not, remove sun gear.
1) Drive the spring pins (or roll pins) planet shafts of carrier (6) .
(14)
(30) completely into the
using a pin punch. Press planet shafts out
6) The secondary planetary assembly (includes items 5,
7, 13, 15, 16, 24 & 29) is splined to the output shaft (4) .
It may now be lifted, by hand, from output shaft spline.
NOTE: Support primary carrier (6) only while pressing planet shafts.
2) Slide planet gears (8) and primary planet washers (17) from carrier (6) .
The unit is now disassembled into groups of parts and/or subassemblies. The area(s) requiring repair or service should be identified by thorough inspection of the parts after they have been washed in solvent.
3) If any of the primary planet bearings press them out of planet gears.
(25) need replacing,
4) Check primary planet shafts (14) for any abnormal wear, especially ones in which bearings needed to be replaced.
If any abnormal wear is found, replace planet shaft.
5) Using a punch, drive roll pins (30) out of planet shafts (14) .
6) Press new primary planet bearings (25) into planet gears, if required.
7) With a primary planet washer (17) on both sides of planet gear and bearing installed, slide gear into carrier (6) and insert primary planet shaft (14) through carrier, planet gear, and washers. During planet shaft installation, align roll pin hole in planet shaft with the roll pin hole in outside diameter of carrier.
NOTE: Inserting a 1/8” diameter punch in roll pin hole of planet shaft will help in the alignment of holes between planet shaft and carrier during Step 7.
8) Once holes are properly aligned, drive a roll pin (30) through primary carrier and into planet shaft to retain parts. Use a drift to drive roll pin flush to carrier and to prevent striking planet gear teeth.
9) Repeat same process for remaining gears.
Steps with an asterisk (*) apply only to the double planetary model.

Secondary Planet
Carrier Subassembly
Base Subassembly
Disassembly
Follow the same procedure as that for the Primary Planet
Carrier Subassembly, except substitute item numbers as indicated: secondary carrier (5) , secondary planet gear (7) , secondary planet shaft (13) , secondary planet washer (16) , secondary planet bearing
(24) and secondary roll pin (29) .
Disassembly
1) Place unit on a press table with the output shaft (4) pro truding downward through a hole in the table; unit should be supported only by the base (1) . The only thing retaining output shaft (4) is the retaining ring (22) . Remove the retaining ring
(22) , spacer (23) and shims (10).
CAUTION: Retaining ring is no longer retaining output shaft.
Take precautions if the unit is moved: the shaft may fall out.
2) With output shaft down through centerhole in press table and unit supported by base, press shaft out by applying press load to top end of shaft (internal end) until it passes through inner shaft bearing (19) . Outer shaft bearing (18) and seal
(34) will come out of unit attached to shaft.
3) Inspect inner and outer bearing cups (20 & 21) . If cups are damaged, the cups and base (1) may need replacement.
Contact Eskridge if you have questions.
CAUTION: Care should be taken not to injure feet or damage output shaft during this procedure.
4) If outer bearing cone (18) needs to be replaced, it will need to be pressed off of output shaft. Also inspect inner bearing cone (19) .
NOTE: When installing or removing bearings, press only on inner race of bearing cone. DO NOT press on outer roller cage of bearing or it will damage bearing.
5) Clean all foreign material from magnetic oil plug (32) located on bottom of base (1) . Add a small amount of pipe thread compound to pipe plug before installing it back into base.
Steps with an asterisk (*) apply only to the double planetary model.

1)
Unit Reassembly
Start with base (1) . Turn base upside down and position on press table. Base should be pointing upward with outer bearing cup (20) exposed. Apply a layer of lithium bearing grease to bearing cup surface.
11) Install secondary carrier assembly into unit. Carrier assembly should be installed with hub side down (24 tooth spline) .
Rotate carrier assembly back and forth to mesh secondary planet gear teeth (7) with ring gear (2) teeth. Once teeth mesh, let secondary carrier slide down until it contacts with output shaft spline. The carrier splined hub (5) should spline onto output shaft (4) . Carrier hub will rest on top of retaining ring (22) when splines are fully engaged. Check to be certain carrier cup washer (15) is installed.
2) Invert output shaft (4, retaining ring groove end down) and carefully lower into base (1) until the shaft’s outer bearing cone (18) is seated against outer bearing cup (20) .
3) Press shaft seal (34) into base until it is flush with bottom of pilot diameter. Use a press fixture, if possible, to avoid distorting seal. If press fixture is not available, a hammer and flatended drift may be used by tapping outer edge of seal lightly and alternating sides.
*12) Turn primary carrier assembly upside down so that splined end of carrier (6) is up. Insert splined end of secondary sun gear (11) into carrier spline until fully engaged. Install carrier assembly into unit, sun gear down. Sun gear teeth will mesh with secondary planet gears, and primary planet gear teeth
(8) will mesh with ring gear (2) .
4) Stand base assembly upright on output shaft.
CAUTION: The only thing holding output shaft and base together at this point is the tightness in fit of the shaft seal.
Securely and cautiously turn unit upright, not allowing base and shaft to separate.
13) Put input thrust washer (26) over step of input gear (12) .
Insert input gear into unit so that teeth mesh with planet gears.
5) While holding output shaft (4) with one hand, rotate base felt, if any, is due to shaft seal load (drag) on output shaft.
(1) to be certain it turns freely and smoothly. The slight resistance
14) Grease a new o-ring (33) and install it into bottom of cover/ bail assembly (3) . Refer back to scribe marks made across external joints prior to Disassembly Procedure. Line up scribe marks between cover/bail assembly and ring gear (2) so that orientation of motor mount holes and oil plug are back to their original positions.
6) Apply a layer of lithium bearing grease to inner bearing cup
(21) surface.
NOTE: Be certain o-ring (33) stays seated in cover/bail assembly during Step 15.
7) Install inner bearing cone (19, small end down) over internal end of output shaft. Press bearing on slowly until it is just seated against bearing cup (21) . With a slight press load still applied, rotate base (1) by hand to ensure roller bearings are rotating evenly and smoothly. Inner bearing cone (18) may require additional press load to reach proper bearing preload.
If roller bearings are seated properly, continue on to set and check bearing preload.
15) Install all twelve of the 7/16 lockwashers hex capscrews (27) and torque to 70 ft-lbs.
(31) and the 7/16
16) Fill unit with 2.5 pints of a GL-5 grade EP 80/90 gear oil.
Proper oil level will measure to middle of primary planet gears
(8) .
17) Lift bail assembly (42) onto planetary unit. Align access hole with motor ports. Secure with six hex head capscrews (38) , lockwashers (36) and nuts (37) ; torque to 55 ft-lbs.
SHAFT BEARING PRELOAD: Proper shaft bearing preload is achieved when torque required to rotate base is 50 to 80 inlbs. This rolling torque is equal to a force of approximately 11 to 18 lbs if pulling on base flange to rotate base (1). This may be determined by feel or by using a fish scale or similar measuring device to check rolling torque. screws motor

shims over internal end of output shaft (4) . Shims should slide all the way down to outer bearing cone (18) , where they will rest. The same number (quantity) of shims removed from unit during disassembly should be returned.
Follow shims with bearing spacer (23) . Spacer will sit directly on top of bearing shims.
NOTE: Quantity of shims (10) may vary from unit to unit.
Bearing preload, set at the factory, determines quantity of shims.
9) Install a new retaining ring (22) onto output shaft.
10) Lightly grease a new o-ring (33) and install it into o-ring groove in base (1) . Assemble ring gear (2) to base (1) . Refer back to scribe marks made across external joints of gear drive prior to Disassembly Procedure. Line up scribe marks between ring gear and base to give correct hole alignment.
NOTE: Be certain that o-ring (33) stays seated in groove during Step 10.
