crankshaft bearings. A chain running too slack may run off the sprocket or
chainwheel.
Adjust the dynamo drive “V” belt tension (if fitted) by altering the position of the
dynamo on the slotted adjuster so the belt deflects approximately 12mm, check
midway between the pulleys.
Refit the guards, not forgetting the plastic plug, top plate closing plate, exhaust
extension and engine housing support bracket.
Dynamo Drive Pulley Removal/Replacement
If a dragline option is fitted an alloy “V” belt drive pulley is fitted onto the extension
shaft prior to the sprocket.
To remove follow the above procedure and remove the engine sprocket and dynamo
drive belt, mark the position of the pulley on the shaft. Undo the grubscrew retaining
the pulley and slide off the pulley.
Reverse the procedure to fit the new pulley smearing the bore with anti-seize
compound prior to fitting.
Check the drive chain alignment and tension as described above, adjust the dynamo
drive “V” belt tension by altering the position of the dynamo on the slotted adjuster
so the belt deflects approximately 12mm, check midway between the pulleys.
Refit the guards, not forgetting the plastic plug, top plate closing plate, exhaust
extension and engine housing support bracket.
Hydraulic Pump Removal/Replacement-Hydraulic PTO (Not Direct Drive)
The hydraulic pump is secured via four studs to an adapter plate, which is in turn
bolted to the engine gearcover, and it is not possible to remove the pump without
removing the backplate. The pump is driven by a gear mounted on the pump shaft, it
being driven by a gear bolted to the end of the crankshaft. The pump being clockwise
rotation.
Ensure any residual hydraulic pressure is dissipated as previously described. Place a
suitable container below the hydraulic pump to catch any hydraulic and engine 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.
Remove the four nuts and bolts securing the backplate to the engine and carefully
remove the pump and backplate assembly. Note early backplates are fitted with a
gasket between the plate and gearcover whilst later engines have an ‘O’ Ring fitted.
Hold the assembly in a suitable soft jawed vice and bend back the tabs on the
tabwasher locking the driven gear retaining nut. Remove the nut and any washers,
