ADJUSTING THE MIDDLE GEAR BACKLASH
1. Loosen:
• Middle driven pinion gear bearing housing
bolts
2. Remove:
• Middle driven pinion gear shim(s)
3. Tighten:
• Middle driven pinion gear bearing housing
bolts
NOTICE
ECA2S31049
Do not overtighten the middle driven pinion
gear bearing housing bolts or you may ob-
tain too little middle gear backlash and dam-
age the middle gears. If the bolts are
overtightened, loosen them until the crank-
case-to-middle-driven-pinion gear-bearing-
housing clearance is within specification, as
stated below. Then, repeat all of the previous
steps.
