After reassembling my 1948 262 engine, I find I am unable to set the timing.
Unlike other cars where the oil pump is driven by the distributor, the Hudson has the oil pump driven by the camshaft and the distributor is driven by the pump. When I reassembled my engine, I noticed the flat tab of the end of the oil pump shaft, but I didn't realise that it would only fit the distributor one way. Now that I have it all back together, my rotor is about 180 degrees away from where it used to be. I relocated my plug wires in the cap, and managed to get the engine running, but there isn't enough of a slot at the hold-down bolt. I can't rotate the distributor enough to properly time it. I also tried moving my plug wires back one hole to compensate, but now it won't even start.
So I'm thinking I will have to remove the oil pump again and reset the position of it's shaft. Is this correct? Is there a certain position it must be in at top dead center?
I'm sure someone else has run into this before. Does anyone have some advice on what to do here?
The weather is gorgeous - I should be out driving this thing and I'm SO CLOSE!!
Thanks for any advice!
Ahhh - Further research indicates that I need to reposition my oil pump shaft, but I don't have the alignment tool. Maybe I should ask this question and I'll figure out the rest:
With my engine in #1 firing position, at what clock position should my rotor be pointing? I think it was just before 12:00 before I took it apart. Does this sound correct?
Mike,
I have also wrestled with these issues. Regarding the rotation of the distributor for timing, there is an adjustment on the underside of the distributor that allows a lot more movement. When you locate that bolt, set it near the right spot and then use the regular adjusting bolt to get it fine tuned. Also, I too ended up with the oil pump gear 180 degrees out of position. I tried several times to get it right but it seemed that the close working conditions under the engine kept giving me fits. Finally I left it 180 degrees off and moved the wire locations as you did. In its normal position #1 cylinder fires at about 1 o'clock. When its 180 degrees off, it fires at about 7 o'clock. Mine works fine that way.
Good luck,
Ed
Mike,
Chk PMs.

Thanks for your suggestion Mr. Schmidt. I loosened off that other screw and got enough adjustment to time my engine correctly! Good idea - I never noticed that screw before.
