Type A OD Mounting Question

[Tinkerman]

Afternoon All:

I'm getting ready to mate the OD to the tranny and I see that the two center studs are about 1.25" longer than the other studs. How come? I don't see anything in the catalogs or manuals that would indicate additional items to be mounted there or is there?

Anyhow your thoughts on the matter will be greatly appreciated.

Tried to attach a picture but the system wouldn't let me.

The longer center studs are used to compress the springs. Once the OD is installed, the excess length just hangs out in space.

Be VERY careful here, as it's easy to distort the adapter plate if things hang up for any reason. If the nuts seem to be getting harder to turn, stop and deal with the problem instead of continuing to tighten them.

Also, IIRC, you have to stop before the plate is fully home against the OD housing, to start the nuts onto the other studs. There isn't room once it's all the way home.

Here's Nelson's shot of the other nuts being installed, showing one of the long studs protruding.

Also, I remember there is some business of pulling the pump plunger back with a piece of wire or something like that; otherwise you won't be able to put it together. (Hopefully you've got that covered!)

Thanks Randall, suspected as much. The tranny I am using and the OD as well came from the PO and I did not un-mate them (so to speak) In fact the longer studs were nowhere in sight so they came from TRF. The Nelson Reidel articles have been my main source on info, that and the Haynes Manual on both the tranny and OD projects. Spannerman, if I had been able to include the picture you would have seen my hold down wire, but thanks for the reminder.
Thanks to both of you for your comments.
These two projects have been a challenge from the git-go. Unless you work on them all the time they are a bewilderring array of gears, bushings, thrust washers and other parts. Murphys law hovered over these two projects like a swarm of bees. If it wasn't for the BCF, Charles Vincent at Vinco Transmissions and others, I would have given up weeks ago. Well maybe not, but it would have been much tougher.
Next week will be the acid test, the pressure test!

Again thanks to all of you for responding to my questions, Tinkerman
