GEARBOX DISASSEMBLY

1.Remove 6 (16) bolts from input shaft bearing housing (13).

2.Tap around circumference of bearing housing (13) to loosen housing and shims. Then pull complete shaft

(9)and housing assembly out of main housing. Figure Mnt-R-0247

3.Remove 4 bolts (18), break gasket (11 & 12) loose, and then remove the bearing retainer cap (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.
