Unlike the diesel driven versions it is possible to remove the pulley without removing
the motor. To remove the pulley, first remove the engine housing closing and top
plates, upper and lower belt guard and ‘V’ belt. Mark the position of the pulley on the
shaft. Turn the motor shaft until the grubscrew is visible slacken the screw and
remove the pulley. Reverse the procedure to refit coating the bore of the pulley with
anti-seize compound prior to assembly.
Fit the “V” belt and confirm the alignment of the pulleys. Adjust the height of the
motor to tension the “V” belt. The tension is correct when the belt deflects 12mm
check midway between the pulleys.
Refit the engine housing closing and top plates and upper and lower belt guards. Not
forgetting the plastic plug
The hydraulic pump is driven by toothed drive adapters and nylon sleeve mounted
directly on the opposite end of the motor. The pump is mounted on a mounting
bracket, which provides some degree of adjustment to enable correct alignment of
the toothed adapters and nylon sleeve.
When a dragline is fitted a ‘V’ belt pulley, (available separately) to drive the dynamo
is welded to the rear of the toothed adapter mounted on the motor.
Hydraulic Pump Removal/Replacement
Remove the engine housing closing plate.
Ensure any residual hydraulic pressure is dissipated as previously described. Place a
suitable container below the hydraulic pump to catch any hydraulic oil spills, remove
and plug the supply and feed hoses and plug the ports in the pump to prevent the
ingress of dirt and foreign matter.
Un-bolt the hydraulic pump from the mounting bracket and withdraw leaving the nylon
sleeve on the motor shaft.
Hold the pump assembly in a suitable soft jawed vice and bend back the locking tabs
on the tabwasher locking the toothed adapter retaining nut. Remove the nut and any
washers, the adapter is keyed onto a tapered shaft using a small woodruff key,
remove the adapter taking care not to lose the key.
Reverse the procedure to refit the pump, taking care not to dislodge the woodruff key
as the adapter is fitted. Bend over the tabwasher to lock the retaining nut in place.
Bolt the pump in place on the bracket inserting the driven adapter into the nylon
sleeve.
It is important that the motor and pump are in line to prevent premature failure of the
nylon sleeve. Connect the hoses to the hydraulic pump. Top up the hydraulic oil
levels. Mop up any oil spills.
