Tightening Instructions for 618 Hubs
Proper setting for the tapered roller bearings is described in the following procedure. Always use a new cotter
pin when making adjustments to the hubs.
1. Tighten the castle nut to 20 foot pounds while turning hub. Then back the nut off 1/2 of a turn. Spin the hub
2 or 3 times. While slowly turning hub clockwise, finger tighten the castle nut until castle nut notch lines up
with hole in axle. If notch will not line up, back off nut to next notch.
2. Put the cotter pin in the axle hole. Before bending the cotter pin, spin the hub. The hub should free wheel
from 1 to 2 full turns.
3. If the hub spins the right amount, finish installing the cotter pin by bending the ends.
4. Coat the inside of the dust cap with a thin coat of grease by using your gloved finger. Then install on hub
using the right dust cap driver.
5. Wipe off all excess grease from hub and axle.
There should not be any drag noticed when spinning a tire installed on a hub. If the axle nut
is too tight, the rollers of the wheel bearings will remove the grease from the bearing races,
decreasing the life of the bearings.
HYDRAULICS
Periodically clean dirt and debris from the bottom
side of the depth stop ring.
Inspect hydraulic hoses, fittings and cylinders for
wear or leaks. Use a piece of cardboard or wood
rather than hands to search for suspected leaks.
Replace if necessary.
Before applying pressure to the hydraulic system,
be sure all connections are tight and that the hoses
are not damaged.
Replacing Nylatron Bushings in the Castor Pivot Sleeves
When replacing the Nylatron bushings in the castor
pivot, use the following procedure. Install the
Nylatron bushings (364-001) with holes 90 degrees
to the grease fitting holes. Once installed drill
through the bushing with a 7/32 diameter drill, using
the grease fitting holes as templates.
