Lubrication & Maintenance Using the chart below, determine an appropriate lubricant viscosity. Use only EP (extreme pressure) or API GL5 designated lubricants. Change the lubricant after the first 50 hours of operation and at 500 hour intervals thereafter. The auger drive should be partially disassembled to inspect gears and bearings at 000 hour intervals.

A gearbox exposed to the direct rays of the sun or other radiant heat sources will operate at higher temperatures and therefore must be given special consideration. The max operating temp must not be exceeded under any circumstances, regardless of ambient temperature. If your unit was specified shaft up or with a Z option, a grease zerk was provided in the base housing. For shaftup operation, the output bearing will not run in oil and must be grease lubricated. Use a lithium based or general purpose bearing grease sparingly every 50 operating hours or at regular maintenance intervals. Overgreasing the output bearing should be avoided as it tends to fill the housing with grease and thicken the oil ESKRIDGE MODEL D0 OIL CAPACITIES Operating Position Oil Capacity Oil Level Single stage Double stage Triple stage Horizontal Shaft To horizontal centerline of auger drive Vertical Shaft (Pinion Down).75 Gal / 0.

Base Subassembly (Items,, A, 0A, 0B, 0C, 0D, 0A, 0B, 5A, 5B, 5C) 5C 5B 5A 0C 0A 0B 0A A Disassembly 0D 0B 0A ) Remove the lock ring (5C) using a heel bar or puller; if using a heel bar, be sure not to pry against the cage of the inner output shaft bearing (0C). Remove the split ring segments (5B) and shims (5A). Caution: Since the output shaft is no longer retained, care should be taken to avoid personal injury. Care should also be taken not to damage it when it is pressed through base.
) Base () should be set pinion side down, as shown, on a plate or table. Press output shaft () through the bottom of base by applying a load to top end (internal end) of shaft until it passes through inner shaft bearing cone (0C). Note: Removing the shaft from the base assembly damages the shaft seal and the seal will need to be replaced. ) A gear puller may be used to remove the outer bearing cone (0A) from the shaft (). If reusing old bearing cone, do not pull on or damage roller cage. Remove the shaft seal (A) from the shaft for replacement. ) Inspect inner and outer bearing cups (0B & 0D). If cups are damaged, drive them out using a brass drift and utilizing the bearing knockout notches in the base (). Reassembly ) Clean all foreign material from magnetic oil plugs (0A) located in the base (). ) Place base () (output side up, opposite shown) on the table. ) Apply a layer of lithium or general purpose bearing grease to the roller contact surface of outer bearing cup (0B). ) Press outer bearing cone (0A) (large end down as shown) onto the output shaft () until it seats against the shoulder. Note: Press bearing cone onto output shaft by pressing on inner race only. DO NOT press on roller cage, as it may damage bearing. 5) Place the shaft () with the bearing cone (0A) into the base (). ) Flip this assembly, resting the base () on the end of the output shaft (). 7) Apply a layer of lithium or general purpose bearing grease to the roller contact surface of the inner cup (0D). Press the inner bearing cone (0C) (large end up as shown) onto the shaft () until it is seated against inner bearing cup (0D). 8) Without the shaft seal (A) installed, the preload may result in a rolling torque that varies between 50 to 00 inlb. The bearing preload should be tailored to your application; a lowspeed application may require a high preload, highspeed applications usually benefit from low preload. Adding shims (5A) will increase the preload on the bearing set. Determine your preload requirement and install shims to obtain this preload. Install the LoadNLock split ring segments (5B) over the shims (5A) and into the groove in the shaft (). Install the lock ring (5C) over the split ring segments (5B). 9) Lubricate inner lip of new shaft seal (A) and slide it onto the shaft () and over the shaft seal diameter then press the seal into the base () until flush.

Align mounting holes of ring gear with holes in base (). Use the scribed line made during disassembly for reference. ) Install the input gear () into primary carrier assembly (7). Install thrust bearing (G & L) on top of input gear. ) Lubricate oring (B) and install on the pilot of the cover (). ) Noting the scribed line made during disassembly, install the cover (). Temporarily install two hexhead capscrews (5B) to hold assembly together. ) Ensure the unit spins freely by using a splined shaft to drive the input gear (). 5) Install motor (50) onto cover () with hexhead capscrews (5A) and lockwashers (5G). Torque the capscrews to 0 ftlbs dry, or 80 ftlbs if fasteners are lubricated. ) Remove two temporary capscrews installed in step. Place bail (5F) onto assembly, aligning holes in bail and cover using scribed line made during disassembly as a reference. Install and torque the twenty 5/8 hexhead capscrews (5B) with lockwashers (5H). Torque the capscrews to 0 ftlbs dry, or 70 ftlbs if fasteners are lubricated. 7) Fill the unit to the proper level, as specified, with GL5 EP 80/90 gear oil after it is sealed with a brake and/or motor. The digger is now ready to use. Model D0 service manual, SMD07F0C7 Page Eskridge, Inc. Olathe, KS. 9788
