[WPTA] 1500 Spitfire oil pump install

I’d pull the distributor and see if the pump will then fit. And then place the distributor back into the engine.

>From looking at the repair manual and parts manual it looks like it should slide right in.  It's been a long time since I've had an oil pump out of a Spitfire engine.  Probably 30 years so mostly going by memory which isn't too good.  Anyway, you mentioned below that "nothing was moved or loosened at the distributor".  Actually you spun the camshaft and the distributor when you spun the crankshaft.  I think the oil pump shaft slot (at the bottom of the distributor) is slightly off center so you may have to spin the oil pump shaft 180 degrees to get them to line up.  That's about all I can think of right now.

 

Hope that helps.

I started the process of replacing thrust washers in my 77 Spitfire this spring and after encouragement from a Triumph Spitfire restoration and support forum, also tried replacing main bearings and rod bearings in place.(for better or worse). In order to access the mid-crank rod bearing bolts, I removed the oil pump (cover plate, inner rotor, outer rotor shaft assembly). Now that all the work is complete and the engine spins as expected, the oil pump inner rotor and shaft will not slide fully back into place - it fits into its slot but stops at ~ 1 - 1.5" from fully inserted. 

I can see the slot at the end of the distributor assembly and a second opening in a plate for the inner rotor and shaft to slip through which must be blocking the shaft. The inner rotor shaft assembly spins easily. Any ideas on what can be displaced that won't allow the shaft to completely slide into place would be helpful. Nothing was moved or loosened at the distributor - I only worked on the lower end to replace thrust washers and main plus rod bearings. Some pics attached.

 

thanks for feedback (at least serious feedback :-).
