Convert oil pump rotors
« on: December 21, 2021, 08:51:44 AM »
Hmm…
As I was assembling the converter oil pump on my Convert I found a contradiction in the Work Shop Manual (or maybe just in my head).
The two rotors are marked and the marks are supposed to go on the same side. My question is: what side?

From Gregory Benders fantastic site https://www.thisoldtractor.com/mg_manuals/workshop_manual_convert.pdf
Looking at fig 272, it looks as if the marks “1” should go towards the camshaft.

However, on page 140 the manual states; “First pay attention that, when mounting the pump onto the valve gearing cover, the two rotors show the reference mark “1” outwards...”
What does “outwards” refer to? Outside the engine? That would mean away from the camshaft.

So, does anyone know how to position the rotors?

I believe they are talking about the front cover not engine. Facing outwards of cover not from motor. It's assembled in the cover not in motor. It would face the cam or the motor.

It is still unclear to me. They may very well refer to the front cover, but is "outwards" towards the exterior or interior of the cover??

If it was the other way it would say "front" like it says throughout the manual.
