Distributor installing
« on: June 03, 2011, 06:49:56 pm »
So, ive read a few post recently about fighting the oil pump shaft when trying to install the distributor and having to turn it with a flathead screw driver to line it up. well, the tecnique i use works wonders! The advice i have is, IGNORE THE OIL PUMP SHAFT POSITION. Just forget it. instead, line up your rotor how you please, and set it in the hole. Now, if the distributor doesnt go all the way down, its because the oil pump shaft isnt lined up. Thats OK! Bump the starter over and it should fall down onto the pump shaft. If it doesnt, push down on the distrobutor and have someone bump the key. It keeps your timing where you want it and you dont have to waste half the day lining up the shaft. I hope this helps someone.

When the distributor is not seated all the way, are the gears meshed? I wouldnt do that if the gears arent meshed completely, IMO...

The gears are meshed, its just not fully seated on the oil pump shaft, when you bump the starter, the distributor turns and it lines up the oil pump shaft and then it fully seats.

it usually takes only a couple more tries when it doesn’t seat of just moving a tooth over or two cause that means your off tooth if it doesn’t slide right in if nothings been moved the oil pump shaft should of turned a tad when you removed the distributor. So when you put it all back it should just fall in place when you set it back in place. notice when you pull the distributor out the rotor will move a 1/4" or so that’s where you should start from when you put it back in is where it came out not where it was before it was touched

Irish, im talking about when you start from scratch. When you pull the distributor and bring #1 piston to tdc and then put yohr distributor back in. Your oil pump shaft will most likely not be lined up then.

It's not a huge issue to just turn the oil pump shaft.  you can see by the rivets on the side of the gear on the bottom of the distributor where it needs to be...

In any case, thanks for the thought...
