H70 HUB ASSEMBLY
To assemble and adjust the setting of this
hub:
NOTE: CLEAN THREAD BEFORE ASSEMBLING, IF
YOU ARE ASSEMBLING A NEW AXLE USING 1-
UNF DIE NUT, CLEAN ALL OTHER COMPONENTS.
Step 1: Clean and prime the seal #3 and seal ring
#9 Fit seal to seal ring using Loctite 480, allow to
dry before proceeding.
Step 2: Fit bearing cups #1 and #2 into the
hub, place bearing cone #1 into the hub.
Step 3: Fit the seal and seal ring to axle, ensure
this does not rotate on axle, use loctite 680 if
required.
Step 4: Fit the hub to the axle, then fit the
bearing cone #1, washer #8, and nut #5.
Step 5: Tighten the nut while turning the hub.
When there is a tight bind on the bearing, the
parts are seated correctly, approx 150ft/lbs.
Step 6: Back the nut off 1/6 to 1/4 of a turn or
sufficiently to allow .005mm to .02mm end play.
Note: Failure to back off adjusting nut could cause
bearing to run hot and fail.
Step 7: Insert the split pin #7 as shown, trim the
straight leg, bend the other over the axle end.
Step 8: Fit the cap #11 using loctite 515 flange
sealant on the faces, and tighten the 3 M8 #6 cap
screws 16nm(12ft/lbs).
Step 9: Grease with a grease gun using CASTROL
BTX
or similar until grease is visible through rear seal.
