distributor removal

I need to pull the distributor for inspection, are there any problems returning it back to its home? These have a face drive rather than a helical splined gear, correct?

Howdy,

It's not too hard to pull a distributor, but you here's some things that will make it easier:

(1) You need the tools necessary to rotate the engine over manually. This is so you can position it at TDC cyl 1. In my case (4.5 W108), I need a 27mm socket and the correct size extension.

The reason this is good is that if, once the distributor is reinstalled, the car doesn't run, you'll have to get it set near TDC.

(2) You need the tools to set the timing. It's damn hard to get it back in exactly the way it came out.
If it's been some time since the distributor has been out, it can be very tight. My advise is to just keep working it and don't force it.

I'm sure others with more real mechanic's experience will provide much more detail.

Hi Mark,
You're right, the distributor has an offset drive piece instead of a gear at the bottom. You really have to "try" to get it in wrong. Just look at the general direction the rotor is facing when you remove it and put it back that way.
