WATER PUMP INSPECTION AND
Fitting ladder frame
. ...
,.
The water pump is not a reconditionable unit but its
condition can be determined by the following
checks .
Since the sealant specified t o seal the ladder frame
to the crankcase cures within fifteen minutes it is
important to fit sufficient bolts to ensure adequate
compression while the
cures.
1.
Spin the pump spindle and listen for bearing
noise, also push and pull the spindle and
check for sideways movement. If the bearing is
in good condition the clearance between the
and the p ump body should not vary.
Inspect the vent hole in the pump body for
signs of coolant or lubricant leaks. If there is
any evidence of leakage, the pump should be
renewed.
Clean both sides of the ladder frame and
of old sealant. Check that the
frame is not distorted and is free from burrs
and damage o n the mating faces that could
cause oil or bypass gas to leak.

2. Coat both faces with Hylogrip Primer to clean
and hasten curing then apply a bead of

wide to the mating
face with the crankcase.

3. Fit ten securing bolts through the ladder frame
flange and two more through the sump face as

Clean the threads of the water pump retaining
bolts and apply Loctite 572 thread lubricant
sealant t o the threads of the long bolts which
penetrate into the cylinder block.
5.
Fit the pump t o the cylinder block and secure
in accordance with the bolt chart. Tighten the
six bolts and o ne nut evenly to the correct
torque.
OIL PUMP OVERHAUL
Bend back the lock washer and release the nut
securing the strainer to the oil pump body and
remove the. strainer a nd sealing ring.
Remove the four bolts and washers, lift off the
oil pump cover and remove t he driving and

3. Remove the oil pressure relief valve plug and
sealing washer. Withdraw the relief valve spring
and plunger and examine for wear and scores.
4. Examine the gears for wear, scores and pitting
and renew if necessary. Note: Gears must be
renewed in pairs only.

. If separated, fit t he fan blades t o the viscous
coupling with the four screws. Fit the fan and
viscous coupling assembly t o the water pump
spindle noting that it is secured with a
left-hand thread. If air conditioning is fitted do
not at this stage fit the drive belt until the
