KA24DE China Oil Pump Rebuild w/ OEM Parts? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, I posted in the small questions thread and it was ignored, but I need this info now as I'm ready to order parts for my rebuild. I recently had to scrap my oem oil pump. Somehow the chain ate the lower guide AND the inside of the pump and I didn't feel comfortable reusing it. Being in a pinch with an event that weekend I threw my spare on, which is an OE replacement. Not sure of the brand, but I can only assume it came off the same assembly line in Taiwan as the rest of them. The motor blew up that weekend(ringland failure) so it's apart.

My question is, can I simply order oem parts from nissan and rebuild this pump for peace of mind? I guess worst case ontario I can find a used oem pump and rebuild that, but if I can I'd rather just use this one as it has been decked with my block.

Thank you for the help!

Also while I'm here, what Clevite part number do I need to order? My crank is perfect so I only need standard size, but I'm coming up with MS2080P and MS1949P for the mains and CB1589A and CB1589P for the rods.

Bearing numbers are good they offer h series for race apps ps will work fine though. I couldn't find my old pump to mike the gear I'd assume they are the same though. It'd be a good time to shim that relief for a little extra pressure.

I replaced my front timing cover & oil pump not too long ago. Picked up an aftermarket cover, then swapped all oil pump components with OEM. Picked them up from FRSport.

Reimax makes a rb gear set 77mm and 81mm 11mm thick and sr 10.2 I wonder if those would fit as well for you.
