DANGER! Do not operate this Equipment with hydraulic oil leaking. Oil is
expensive and its presence could present a hazard. Do not check for
leaks with your hand! Use a piece of heavy paper or cardboard.
High-pressure oil streams from breaks in the line could penetrate the
skin and cause tissue damage including gangrene. If oil does
penetrate the skin, have the injury treated immediately by a physician
knowledgeable and skilled in this procedure. (SG-15)
2.1 Tighten Instructions for 618 Hubs
Proper Settings 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, hand 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 soins 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.
IMPORTANT: There should not be any drage 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.
2.2 Hydraulics
Periodically clean dirt and debris from the bottom side
of the depth stop ring.
Inspect hydraulic hoses, fitting 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.
