New Distributor Fit

I purchased a new distributor for my 2.25L and I'm having trouble with the fit. As you can see from the pictures, it won't fit all the way into the bracket\mount.

It's hanging up on the o-ring. I took the o-ring off as a test and it fit completely into the mount. What should I do? I can hone the mount slightly with a master cylinder honer. I could try and force it.

Suggestions?

Can you find an O-ring that is not quite as thick?

Stupid question but it has to be asked - you lubricated both the o-ring and the other surface right?

As Dan suggests, you could try a smaller o-ring.
Don't try and hone out the housing... especially since it is cast aluminum and a brake hone won't do much but collect aluminum in the crevices of the stones.

I would try applying some grease or oil to both pieces as they are suppose to fit together.
The vendor could have put a fatter O-ring on it as well.

Once it's in place, the distributor drive has an offset slot that will drop into an opposite shape so it only fits one way around.
You'll need to turn it to set the timing.

Who needs an o-ring? it's not like these damn things don't leak like a sieve anyhow. If it's not leaking it's out of oil. Seriously, this isn't a high pressure area so a slightly smaller o-ring would suffice if you can't get it in using lubricant.

Yes I've lubed the o-ring and the cylinder. There isn't much to the o-ring, but I'll look for a smaller one.

I may just remove it. with the tolerances are tight I doubt it would leak.

I had the same exact problem when installing a new Lucas 45D. The o-ring is a funky size with a small x-section. I ended up buying them through McMaster Carr. I had to buy a whole bag. If you can wait, PM me your address and I'll send a few out.

Paint the thing with some Hylomar, stick it together and put it on the engine.
