I have a high volume, high pressure oil pump , and I just want to change the spring to lower the pressure . A lower pressure spring came with the pump. Do I just take the top of the pump off (remove the 4 bolts) to do this?

Thanks.

 

I believe its just a pin that holds the spring in there..just remove the pin, change spring, and reinsert the pin..

I saw the pin, but how would you get it out?

 

Yes, you do have to have to remove the top to get to the spring pin. No big deal.

 

Thanks.
