I would like to take the distributor on my '72 RR apart to clean it properly. Is this something that can be done without a lot of risk? Cannot find anything in the shopmanuel re electronic distrb. Is there anything I should be careful withl when taking it apart?
Thanks

make sure you put the reluctor on correctly facing the big block position .
weld up the slots if you want to increase your initial timing
Just buy a new MP with adjustable slots if youre not on a budget !

Don't be surprised if that nylon bushing at the base of the distributor cracks,very common.I would replace it with a new one.

When taking it apart there is a retaining ring in the hollow part of the shaft that the rotor covers. It takes two small screwdrivers to squeeze the tips together to get it out. It is a delicate operation that takes patience. And for gods sake. Don't let spring away as you remove it out the top. it'll fly who knows where. Other than that they are pretty easy. Getting the adv ance arm in and out of the plate is a little tricky but no big deal.

If you take the springs off the mechanical advance it can aid in getting the clip off/out. I think there is a small washer under the clip also so be careful. Another thing is if you have any varnish on the shaft clean it off before you attempt to pull it out. It will bind up in the lower bushing.

Agree with all that was said.
Mark where the plate that holds everything goes. If you've never done this before, or don't have another dist.
for reference It can be confusing. Also, DO NOT try to remove the shaft bushing unless you already have a spare. You will most likely break it! And the new bushing doesn't have a hole drilled for the roll pin, this can be tough for a beginner. My advice, leave it be.
