Replaced mine yesterday, easy job, some pointers:

 

) TDC mark on compression stroke (rotor at 7 o'clock)

) Remove top cover plate bolt on old pump to clear frame on some cars

) Prime new pump !!!!!!!!!!!!

) Align slot with mounting holes (looking at end of shaft, as pump is in car), oil ports up.

) Turn shaft counter-clockwise one tooth

) Mount new pump without turning shaft ! (may have to move rotor ever so slightly to seat slot)

) Remove spark plugs and spin motor until pressure starts to build

) Replace plugs and start

thanks for your help, but what am I doing wrong,  I have installed the pump til I am wore out    timing will be  long before tdc and next time long past tdc

You just need to keep turning the gear on the pump before installing it until you find the correct spot.

 

Be sure to raise the distributor slightly per the printed instructions. If you do not, the distributor tang can/will ride on top of the oil pump and can drop in 180 out. Not that it is a big problem. just if you are like me and don't realized that happened you will be scratching your head for a while until someone tells you to check for 180 out.

 

Per printed manual instructions, if you have moved the crank position, find TDC before installing the pump. If you do not have enough thumbs to to put one over the hole, and turn the engine by hand using the fan you can put masking tape over the hole. It will pop off when you are coming up on the compression stroke. Align the gear with the flange holes, turn 1 tooth to allow for gear rotation during install. Determine if you are 180 out by checking for a spark on the compression  stroke by using an inline spark tester.  Edit: this can be done turning the engine by hand, or by turning the distributor when you know you are close. Turning the distributor method will also get you very close to having the engine timed prior to the final check with a timing light.

 

 

 

Instructions call for removing #1 plug. Much easier to turn the engine to find TDC with all the plugs out.
