PLEASE READ CAREFULLY BEFORE DISASSEMBLING OIL
It is entirely possible to make several errors in re-assembling oil
pump components. Draw a sketch that clearly represents the oil pump that
you are repairing. Carefully draw on the sketch:
If more than one mount plate with the same external shape is present, be
careful! One of them will have a "crossport" to allow scavenge out
oil to pass from one stage to another. If this crossport is put adjacent
to the "pressure stage" you will have zero or low oil pressure and a blown
engine!! Separator part numbers 1060 & 1211 may or may not be crossported,
depending on the particular pump assembly. If these parts are assembled
wrong, zero or low oil pressure or broken timing belts will occur.
Use the procedure outlined in these instructions, work carefully, noting
each part as it is dis-assembled. Make adequate notes on your sketch
so that you can re-assemble the pump exactly as it was before it was disassembled.
The orientation of mount plate(s) in relation to the location of the oil
pump drive shaft.
Fitting size, shape, and location. Note that 90 degree and 45 degree fittings
must be installed and oriented properly in the gear body before the pump
Remember to clean all components of the oil system. All your Time. Money,
and Effort in repairing your engine and oil pump will have been wasted
if you do not make certain that all parts of the system are as clean as
possible. Take the time to dis-assemble and clean the oil tank, flush out
all limes. clean or replace filters, etc. If you run a oil cooler, have
it ultrasonically cleaned. The extra effort is worth it!! any
debris or engine trash from your old motor will be pumped into the system,
thus destroying your oil pump and your new motor!
