SHEAR BOLT
In order to protect the driveline against excessive shock loads a shear bolt is provided on the universal joint
assembly between the gearbox and chain case. Should the shear bolt break during operation replace with a
bolt of the following specification:
M8 x 45 mm bolt grade 10.9. with interfering type lock nut.
If possible use original equipment shear bolt part #341-4015.
Tighten nut only enough to draw the shear plates together. Do not over tighten the nut.
Normal wrench torques to not apply. Occasionally apply grease to the shear plates.
Replacement of the shear bolt with one of any other grade or size will be considered
unauthorized modification and warranty will be void.
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.
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil
and fuel are explosive and their presence could present a hazard. Do
not check for leaks with your hand! High-pressure oil streams from
breaks in the line could penetrate the skin and cause tissue damage
including gangrene. To check for a hose leak, SHUT the unit ENGINE
OFF and remove all hydraulic pressure. Wear oil impenetrable gloves,
safety glasses and use cardboard to check for evidence of oil leaks. If
you suspect a leak, REMOVE the HOSE and have it tested at a Dealer.
If oil does penetrate the skin, have the injury treated immediately by a
physician knowledgeable and skilled in this procedure.
SLIP CLUTCH
NOTE: Remove the retaining bolt from the yoke linked to the slip clutch. This allows the slip clutch to float so
the adjustment can be made. Secure the retaining bolt after the slip clutch is adjusted.
If the rock wonderer has been left unused for a period of time, e.g. A month, or even less in
damp, wet conditions, the clutch friction liners may tend to bond to the clutch plates. To free
up the friction liners, the clutch springs should be backed off and the friction liners pried
away from their backing plates. It has been found that simply running the rock wonderer
with the slip clutches loose will not necessarily free up the friction liners and may in fact
cause them to become glazed. The springs should be tightened down to the heights
indicated in the following illustration.
