9. Measure air gaps (K and N)—(see Inspect Drive/
Intermediate Shaft Assemblies). Make any
changes in shim washer (M) and (J) thicknesses
from Shim Kit to obtain proper air gaps.
10. When proper air gap is obtained, gears should drag
slightly against feeler gauge.
NOTE: You may prefer to use a caliper to measure the
drive shaft gear stack. Remove bevel drive
gear only and reinstall rest of drive shaft
assembly. Put calliper over shim washer (M)
and lip of right-side flange bearing (L). Caliper
should read 61.6077—61.7855 mm (2.4255—
2.4325 in.).
11. Apply John Deere Never-Seez® to top surface (O)
of shifter plate and contact portions of shifter shaft
(P) and (Q) with upper and lower case halves.
12. Install shifter fork assembly.
