SRM HIGH DELIVERY OIL PUMP
Fitting and Priming Instructions for BSA A7, A10, A50, A65
Congratulations on purchasing SRM’s Newly Designed High Delivery Oil Pump.
When fitting the pump follow these
instructions carefully and it will give years of trouble free service. We DO NOT
recommend the fitting of any obstruction in the oil lines such as filter kits or
non-return valves! The pump demands more oil from the oil tank and any
restriction in the flow will end in disaster!
Before fitting the new pump you must be 100% sure that the oil system is free of
any particles that might damage the internals of the pump. Drain the oil tank
and the crankcase sump. (The SRM Sump Filter Kit is an advantage making draining
the sump a breeze). For the best results the oil tank needs to be thoroughly cleaned and dried - ideally with a
pressure washer. We also recommend fitting a new crankshaft worm gear and a new
Pressure Release Valve.
Fitting the Oil Pump
1.
Remove old oil pump by undoing the three securing nuts and
then remove the three studs. On the A65 models, retain the oil pump ball and
spring (see picture) remove the pressure relief valve
2. Clean the gasket area then fit a new greased gasket (supplied) taking care to
align the oil ways (do not use sealant).
3. Re-fit the oil pump ball and spring A50,A65 (A7,A10 Needle Roller
Conversion). Use grease on the pump to locate the ball bearing.
4. Offer up the new pump to the crankcases and fit using the new Allen bolts
supplied. Carefully tighten the bolts evenly to avoid tilting the pump. Torque
to 11Nm or 8ft lbs
5.Re-fit the oil supply pipes and refill the oil tank with clean oil. Re-fit the
timing cases using new gaskets
(On
some A10 engines, the inner timing cover can make contact with the Oil pump due
to casting irregularities. In these circumstances some material may need to be
removed from the cover for correct fitment to be achieved.)
Priming the oil system
The oil system and pump
must
be primed with fresh oil before the engine is started.
Ensure the engine is switched off, remove the spark plugs, then using the kick
start gently spin the engine to prime the pump.
Keep turning the engine over using the kick start until a good flow comes
through the PRV housing. Refit the Pressure Release Valve. Refit the spark
plugs.
*Note*
New engine builds - using an oil can, fill the FEED oil line with fresh oil whilst turning the engine over with the kick start. Continue this operation until you see fresh oil from the hole where the PRV fits. Refit the PRESSURE RELEASE VALVE. Connect the FEED oil line to the oil tank and fill with fresh oil to the correct level. The system is now primed.
