SINGLE & DOUBLE PLANETARY AUGER DRIVES
This manual is intended to be used by persons with reasonably mechanical skills and understanding of mechanical components.
This manual will assist in the disassembly and assembly of the above model Planetary Auger Drives. Item numbers, indicated in pa-rentheses
throughout this manual, refer to the exploded parts breakdown drawing. Individual customer specications (mounting hood, output shaft etc.) may
vary from exploded drawing and standard part numbers shown. Contact Digga Australia for enquiries.
For any spare or replacement parts, contact Digga Service and Spares or a local Digga representative. For identication purposes always try to have
available the auger drive unit type and serial number. This information may be necessary for verication of any component part numbers. Component
part numbers and/or manufacturing gear set numbers may be stamped on individual parts. This information may also be helpful in identifying
replacement components.

In all the drive units there are primary and secondary individual gear sets.
UNIT DISASSEMBLY PROCEDURE
All parts should be inspected as they are removed from unit. Scribe or mark a line across the assembly mounting case, ring gear, and cover joints on
outside of gearbox to assure proper orientation of hood assembly, oil ll/ drain plug, motor mounting, etc., as the unit is reassembled.
1. Remove outer ring of bolts (refer to the relevant drive unit- diagram) from underside of gearbox assembly. Lift hood from gearbox assembly.
Remove drain plug and drain oil.
2. Remove hydraulic motor from gearbox assembly. On PD12HD-21 and PD22-20 and above remove 4 motor retaining bolts to remove motor then
inner ring of input housing retaining bolts.
3. The primary planetary assembly is now ready for removal. Lift outer ring gear, sun gear and gear set from the output housing.
4. For secondary planet removal, remove bolts holding interim housing, remove housing, and lift outer ring gear, sun gear and gear set from the
output housing.
5. All drive units will have a seal protector or carrier, remove this before moving to step #6.
6. Remove key steel from keyway. Loosen lock nut using the required tool and remove locknut and locking tab.
7. With output shaft down through a centre hole in hydraulic press table and unit supported by case, press shaft out by applying load to top end of
shaft (internal end) until it passes through inner shaft bearing. Outer shaft bearing will come out of unit attached to shaft.
The unit is now disassembled into groups of parts and/or subassemblies. The area requiring repair or service should be identied by thorough
inspection of the parts after they have been washed in solvent.
BEFORE DISASSEMBLY
CAUTION: RETAINING RING IS NO LONGER RETAINING OUTPUT SHAFT. TAKE PRECAUTIONS IF THE UNIT IS MOVED
BECAUSE THE SHAFT MAY FALL OUT.
CAUTION: CARE SHOULD BE TAKEN NOT TO INJURE FEET OR DAMAGE OUTPUT SHAFT DURING THIS PROCEDURE.

5
OUTPUT SHAFT SUBASSEMBLY
REFER TO APPROPIATE EXPLODED VIEW DRAWING
1. Inspect inner and outer bearing cups and cones. If either is damaged, the complete bearing assembly will need replacing.
2. Remove inner and outer bearing races from output housing with the appropriate tool.
3. Clean all foreign material from oil plug located on bottom of output housing. Add a small amount of pipe thread compound to thread on plug
before installing it back into case.

PM-000150-C Kopenn Auger Drive Service and Repair Manual - March 2018
PRIMARY PLANETARY SUBASSEMBLY
Rotate planet gear to check for any abnormal noises or roughness in the primary planet bearings. At the same time, inspect planet gears for any
damage or worn teeth. If replacement or further inspection is required, proceed as follows. For PD15 - PD22 lift top gear set from bottom set then
proceed as follows.
1. Remove circlips from top plate and remove plate.
2. Slide planet gears from carrier.
3. Remove bottom plate.
4. Check primary planet shafts, top and bottom plates, centre thrust washer, needle rollers and gears for any abnormal wear.
5. Replace any worn items.
6. Assembly: Fit centre thrust washer, t bottom plate, t gears, insert needle rollers into gears using lubricating oil, t top washer and install
circlips to posts place gear set into ring gear and place sun gear into gear set, ensure all turns freely.
CAUTION: THE NEEDLE ROLLER BEARINGS ARE NOT CAGED THEREFORE CAN FALL FREE.
NOTE: IF THE PLANET SHAFTS ARE WORN, THE COMPLETE CARRIER ASSEMBLY MUST BE REPLACED. THE POSTS
SHOULD NOT BE REPLACED IN AN EXISTING CARRIER.

UNIT REASSEMBLY
1. Start with output housing assembly. Turn case upside down and position on table. Bottom seal end should be facing upward and install bearing
cup with appropriate tooling.
2. Install bottom seal or dual seals applying a smear of Loctite 243 thread locker to outside of seal and t using appropriate tooling. Ensure dual
seals oppose each other. Ensure seal is ush with the housing. Wipe off excess Loctite. Grease inner face of seal with EP grease.
3. Invert outer housing to upright position and place over securely positioned output shaft with splines facing upward. Using the appropriate
tooling, assemble the output housing onto the output shaft.
4. Install bearing race to output housing with appropriate tooling. Install bearing ensuring correct installation technique. Only drive the bearing
home via the inner cone of bearing. Hitting outer roller cage will damage the bearing.
5. While holding output shaft with one hand, rotate case to be certain it turns freely and smoothly. The slight resistance felt, if any, is due to shaft
seal load (drag) on output shaft.
6. Fit lock nut with chamfer facing downward and tension.
PD12HD-21 – 180ft/lbs (approx) PD22 – 20 nut tension – 1000ft/lbs (approx)
TK25-20 – PD50-20 nut tension – 1200ft/lbs (approx) Refer to (“Bearing Preload Chart P.12” for correct lock nut tension.)
7. Drive locking tab into the keyway of the output shaft.
8. Insert key after tensioning locking nut.
9. Clean and ensure inner section of housing and bearings are free from foreign matter.
10. For PD12HD-21 – PD22-20. Lightly grease a new o-ring and install it into o-ring groove in case. For TK25-20 and PD50-20, use gasket sealant
sparingly on mating surfaces.
11. Fit gear set and sun gear to the output housing. Line up bolt holes and t ring gear. Make sure the ring gear sits at on the
housing. Top up gear oil level to top of gear set.
12. Grease o-ring and t to interim housing and t interim housing to gear set lining up scribe mark.
NOTE: IF THE BEARINGS HAVE BEEN REPLACED, IT IS LIKELY THAT A NEW KEYWAY WILL HAVE TO BE CUT IN THE LOCKNUT.
NOTE: BE CERTAIN THAT THE O-RING STAYS SEATED IN GROOVE DURING STEP DURING ALL ASSEMBLY STAGES.

9
13. *Fit primary gear set as from step # 11.
14. *Fit o-ring to input housing and t input housing to primary gear set using sealant and aligning scribe mark as previously described.
15. *Fit the hydraulic motor using gasket sealant between motor and housing. Refer back to scribe marks made across external joints prior to
Disassembly Procedure. Line up scribe marks so that orientation of motor mount holes and oil plug are back to their original positions and
ret motor.
16. The drive unit can be lled with gear oil now or after fully assembled. If fully assembled the oil will have to be poured through the bung in the
output housing. Oil quantity is on page 2. Grease a new o-ring and install it into the groove of hydraulic motor. Refer back to scribe marks made
across external joints prior to Disassembly Procedure. Line up scribe marks so that orientation of motor mount holes and oil plug are back to
their original positions and ret motor.
17. Fit hood to gearbox assembly making sure original scribe marks are aligned. Fit all outer bolts and tension to the following setting.
Use Loctite 243 PD12HD-21 (75nm) PD22-20 - PD22 (120nm) TK25-20 – PD50-20 (170nm)
18. Attach hydraulic hoses and test operation.
19. THE AUGER DRIVE IS NOW READY FOR USE.
NOTE: BE CERTAIN O-RING STAYS SEATED IN COVER DURING STEP #12 THROUGH #16.
NOTE: THE DRIVE UNIT CAN BE FILLED WITH GEAR OIL NOW OR AFTER FULLY ASSEMBLED. IF FULLY ASSEMBLED THE
OIL WILL HAVE TO BE POURED THROUGH THE BUNG IN THE OUTPUT HOUSING. OIL QUANTITY IS ON PAGE 2.
