I want to change my stock oil pump for this one I just bought.  I also bought an oil pump puller.  It doesn't look like it would be too hard to swap out.  Is there anyone out there that has replaced their oil pump with one of these?  Are there any things I should look out for or any gotchas I need to be aware of?  Any help before I tackle this is greatly appreciated.  Thanks!

Be sure to pack the pump, and I would fill the filter as well. Sometimes if they are realy tight you can slightly loosen the case bolts.

Be very carefull when starting the engine in cold weather.  With no pressure relieve valve between the pump and the filter, it is easy to blow the seal on the oil filter.

Also it wouldn't hurt to spend a few minutes with a dremel tool to round the sharp edges in the oil passages of the pump to make the oil flow better.  Tom

Make sure the oil galleys line up between the pump and the case If not get a rotary bur in there and open it up to match, although this isn't AS critical on stock motors. Also  Check to make sure the filter cover fits flat on the pump. I put one on a buddies motor and it leaked becasue the pump cover was held out by the case. If you hold the cover up to the case and look behind it you will see where there is a boss on the case that sticks out and can interfere withthe pump cover. I ended up having to clearance quite a bit off the pump cover to fit. This was an Empi 32mm pump. My CB Performance pump that I ran for 15 years didn't have this problem.

thanks for all the advice and help and thanks again to brad!  BTW, I got the transaxle reduction box leak fixed on my buggy with a new spacer and seal kit.  I will try to tackle the oil pump this weekend.
