I have a 1975 dt175 and I'm having my mechanic go completely through the entire motor and replace anything it needs. That being said he doesn't want to touch the oil pump though. (Liability reasons) he said he would tell me how to test it but I'm doing all this work to restore it to mint I dont trust myself. He suggested just putting a new one in it but I can't find one anywhere. So if anyone knows where I can find a new one please let me know. And if they are unicorns now then where can I get reliable rebuilt ones?

DEET here on the forum rebuilds them.

If you're in the UK, I know of someone here that does them.

If you could pass on the UK contact, I'd really appreciate it.

Morning G8uncleal.  I'm getting near to the stage of testing the autolube oil pump delivery flow range for my DT 250B resto. The results will determine whether I need to simply make adjustments to the existing set-up or give the whole pump an overhaul. I'm reasonably confident I can do either option by following advice (including this forum).  I need a contingency plan however just in case it all goes horribly wrong. Please could you let me know your contact source for pump overhauls here in the UK....just in case. Thanks in advance it's greatly appreciated.

Hopefully you should both have received a message from me (it's been a while since I used that function!).
