GEARBOX DISASSEMBLY (Mnt-R-0040)
1. Remove 6 capscrews (Ref.#16) from input shaft bearing housing (Ref. #13).
2. Tap around circumference of bearing housing (Ref. #13) to loosen housing and shims. Then (Ref. #9)
pull complete shaft and housing assembly (See Fig. 8) out of main housing.
3. Remove 4 capscrews (Ref #18), break gasket loose, and then remove the bearing retainer cap (Ref
#2).
4. Output shaft assembly must be removed from main housing by driving or pulling shaft out bottom end.
NOTE: Once lower bearing is out of housing the complete assembly will drop down until top bearing
engages lower bearing bore. To complete removal of output shaft assembly it is necessary to keep
shaft aligned on center line of housing when removing top bearing out bottom end. Normally the
simplest method of removing the output shaft assembly is to attach a slide hammer puller to the shaft
and use that to pull the shaft out
