NP231 SHORT SHAFT "FIXED YOKE" KIT
(Figures 13A) Final Installation
(11) Yoke & Seal Washer installation: (This will apply to both Front & Rear yoke assembly)
(a) Slide the yoke seal into position on the shaft thread.
(b) Lube the yoke as well as the seal with ATF.
(c) A little trick to keep the spline seal in good shape is to slide the yoke half way on and walk the yoke into position
with the retaining nut. Torque to 140-150 ft./lbs. with 1-1/8" socket.
(d) Install your stock speedometer housing into the new tailhousing. Depending on which speedometer gear (tooth
count) you are using will determine the proper rotation of the speedometer housing. Each housing has 4 possible
rotation options. Identify you speedometer gear tooth count and locate that tooth count on your speedometer
housing. The number range on your housing will need to be lined up with the housing retaining clip (see photo).
A touch of RTV Blue silicon around the "o"-ring will help seal the housing to the tailhousing.
(12) Fill to recommended level with ATF.
(13) Reconnect all exterior items: driveshafts, 4WD switch, speedometer cable, etc.
(14) Happy Trails!
