Front Axle Differential Lock, Installing

Install in the reverse order of removal while noting the following:

-- Push the engine/transmission toward the front (a second technician is needed).

-- Slide the front axle differential lock completely onto the transmission. While doing this, join the flange shaft/front axle differential lock centrally with the differential. If necessary, turn on the flange shaft.

-- With the correct tooth position and central guiding, the front axle differential lock slides all the way up against the transmission.

-- Install any cable ties that were loosened or cut off during removal at their same location.

NOTE:

Do not pull the front axle differential lock with the bolts against the transmission, otherwise the front axle differential lock will tilt and the mounting eyes could break.
