Reverse the procedure to fit the new pump not forgetting the new gaskets and ‘O’
Rings, take care not to dislodge the woodruff key when installing the drive gear.
Tighten the pump drive gear locking nut and bend over the tabwasher, Refit the
assembly to the engine and reconnect the hydraulic hoses, top up the engine and
hydraulic oil levels. Mop up any oil spills.
Note, if the studs securing the backplate to the engine are removed from the
gearcase ensure they are refitted the correct way round, i.e. short thread length into
the cover, otherwise they will foul the camshaft and crankshaft gears preventing the
engine cranking over.
Crank the engine over ensuring all is free and correct.
Hydraulic Pump Removal/Replacement-Hydraulic Direct Drive PTO
The hydraulic pump is mounted on a bracket bolted to the gear end cover and
coupled to the engine by a toothed/splined drive coupling with nylon driving sleeve.
The drive being transmitted from the engine by a crankshaft mounted extension
shaft.
The pump being anti-clockwise rotation.
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
the coupling guard held with a single setscrew and washers. Remove and plug the
supply and feed hoses and plug the ports in the pump to prevent the ingress of dirt
and foreign matter.
Slacken and remove the three long bolts, washers and spacers securing the pump
bracket to the engine and withdraw the assembly off the extension shaft, if the nylon
sleeve is retained on the extension shaft slide it off and remove it. Inspect the teeth of
the sleeve for wear or damage, replace if necessary.
The splined drive coupling is retained to the extension shaft by a short parallel key,
setscrew and washers. The threads on the setscrew are sealed with hydraulic sealer
or other suitable compound to prevent oil leakage via the threads down the centre of
the shaft.
Hold the pump and bracket 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, the gear is keyed onto a tapered shaft using a small woodruff key, remove
the gear taking care not to lose the key.
Remove the four M6 bolts retaining the pump to the bracket.
Reverse the procedure to fit the new pump, take care not to dislodge the woodruff
key when installing the driven gear. Tighten the pump driven gear locking nut and
bend over the tabwasher.
