Dial Indicators

[Large Arbor]

Dan,

No they machined the starter mounting plate moving the bendix towards the flywheel, but they went too far. The bendix will now hit the flywheel and not come out. Thus they went to far, likely by .045. The machine shop email me and said they would fix it, but we shall see. I am not paying them another dime to do it.

I have two starters. A new Robb MC starter and a Dynaforce. The machine shop was playing with the starter frame for the Robb Mc starter. I am goign to screw with the Dynaforce. It takes a lot of time to align the bellhousing while the engine is in the car and I am the only one doing it, (i.e. put the bellhousing on, set the dial indicator to zero at 12 o'clock. Get out and turn crank to 9 o'clock, take reading, Get out and turn to 6 and so on. Ugh.)

Ahhh, I see. That's not a lot for them to add back to it... but it should be on their nickel. This seems like it's much harder than it should be.

Exactly.. Should be easier....I could do it if I had the tools....

I hope they can get it right or my last cruises will be when the snow is falling...

Geeez - from one extreme to the other. Well, good luck. Hope they do right by you before the snow flies.

Ok, re-aligned bell housing and I have +5 at 6 o'clock and +6 and 3 o'clock. I have zero at 9 o'clock and 12 o'clock. Do I divide the above and is this good enough?

Also I see some have recommended welding washers to the bellhousing for the dowels. What does that accomplish?

I was thinking of squirting lock tight in the dowels to help hold them in place.

Advice here would be much appreciated.

I take it these are readings of 1/1000 inch. The center of the bellhousing register is .0025 in high and .003 in right (pass side) in comparison to the crank centerline.

I forget what you are running for a transmission. If you are using a Toploader with a pilot bushing, I think those figures are good enough. I usually see not more than .005 out as a limit for use with a pilot bushing.

If you are using a Tremic, especially with a roller pilot bearing, you probably need to consult with their instructions or someone with some experience installing their transmission.

As I mentioned once before you may be able to very slightly shift the bellhousing towards center with the bolts lightly snug by rapping on the side of it with a rubber mallet.

You do not need to weld washers on a Quicktime Bellhousing.

The dowels should not move once the bellhousing is bolted down tight but a little locktight (probably blue - medium strength) would certainly not hurt.

Good luck

Read post #11

This method re-positions the bellhousing holes instead of the dowelpins. Much, much easier and deadnuts accurate.
