it didn't

the best Dave and i could get after numerous attempts was .007, and that's not good enough. it has to be within .005 (recommended for any Manual trans application, not just Tremec)

the dowels i used are an inferior product and that's probably the issue. they weren't offset the amount they claimed... so i'm waiting to get a better/higher quality set on order...

here's what i'm ordering http://www.robbmcperformance.com/products/dowels.html

I have one of those Browell bellhousing tools. Its go or no go. Of course it did'nt go. So , I got some of the lakewood adjustable dowels that you turn with a wrench and got it so the bushing would slide in and then locked it down. Should be fine. I'm installing a tremec so I wanted it perfect. I might be interested in renting the tool out if anyone is interested.

i used the drive in Lakewood dowels

they were supposed to be .014 units but didn't measure out that way... i looked locally for the dowels you're referring to but my local speed shop didn't carry them. they'd have to order which put costs over the ones i linked above...

i'd have been interested in renting the tool you mentioned but i'm already set up with a dial indicator... i know it's probably harder to do this way but it's here and didn't cost me anything...

Personally, I would think the indicator would be more accurate, than the tool, as far as concentricity to the crank center line, but that's just me.



Another issue that is not often talked about on the bellhousing is the surface where the trans bolts not being parallel with the flange that bolts to the block.

I have started (a couple years ago) grinding the trans mounting surface on a flywheel grinder so its accurate. Some are way off.

You can check that with an indicator off the crank, if you set the indicator up to sweep off of the mounting surface instead of the brg surface.

Jeff i forget if it was you or Philip that mentioned that to me a few days ago... i have to clean all the paint from the mounting surfaces and check the face as you're now suggesting (again maybe) uneven(?) paint takes up space...

sure is a lot different from when i was a young man... just slam the bell & tranny together and run it. but that's ok, the quality of parts have improved so i guess it's worth the extra effort to ensure longevity

John we talked about buffing the paint, but I dont think I mentioned checking the face of the bellhousing.




I actually think the older Lakewoods (pre MR Gasket) were more accurate than the later ones.

OK, then it was you well i took it that if the paint was uneven enough to cause the surface to be off then i thought it was meant it should be checked... so that's the plan. i'm hoping all this doesn't turn into a nightmare but i'm going to do it all. i mean, why not. if ya have the tools, USE 'EM
