To Disassemble

For ease of disassembly, mount the auxiliary
section upright in a vise.

Remove the range cylinder capscrews.

Loosen the range piston nut.

Cut the lockwire on the yoke lockscrews and
remove the two (2) lockscrews and actuating
bracket.

Remove the range yoke and cylinder housing
from the synchronizer assembly sliding clutch.

Remove the range piston nut and piston.

Inspect the piston O-rings, replace if damaged or
