Upper hole in tranny case not centered (motor side)
 

I was just taking my aluminum tranny case out to finally install it into my 1/2 case setup, and I noticed the upper hole is not drilled perfectly center. I don't know if it's the hole, or the lip around the hole for the bearing that's not even, but it looks a bit funny. Anyone else get a case with the upper bearing seat off center like this? Will there be any fitment problems with my upper shaft if I stick it in like this? I remember some people complaing their 1/2 case and aluminum case didn't match up smoothly. Is there a newer batch that might not have the defect?:032: Picture is kinda blurry cuz it's still in the packaging -- I might want to send it back...

I see what you mean. If you're lucky, it's the hole and not the counterbore (lip around the hole).If it's just the hole then the bearing will be in the right spot allowing the shaft to be positioned correctly for assembly. That's about all that I have since I'm still running the stock tranny. good luck.

go4gold is right, it's not the hole that centers your shaft, it's the bearings, so if they are aligned properly still you shouldn't have a problem. But i would still send it back because it should be proper. They can't fix the issue unless they know about it as well. If you still have the stock case, use that until you get your replacement. There is my 2 cents!

I have had a problem with every FLM part i've bought. Not touching them again.

I'm pretty sure mine's like that aswell,but as has been said it's not a problem,the hole just has to be big enough to allow the top shaft through

.The problem with mine,and others aswell,is that hole on the other side of the case isn't milled deep enough so it compresses the top shaft bearings and causes binding when you tighten the case.The solution is to either grind some off the end of the top gear or if you have access to a mill then run an endmill in there to make it deeper.Hopefully yours will be OK though.Other thing is, it may need some grinding inside the case to clear the idler gears(mine did)

You just have to understand, with such a small company such as FLM, things like this happen.

FLM has good product. I'm sure if you contact them, or let them know, they willtake care of it. Or, see what Mike can do.

that is a problem with the FLM cases, thought it's not much of a problem, it's just the outer hole isn't centered.

I wonder why on earth they didn't changed it. I had mine when it just came out and i reported it too. it's not that hard to open a drawing and adjust it a bit... :p

I am considering buying the FLM half-case. Has FLM fixed this hole alignment problem?

I think my hole looked off but when put together it lined up like new.
They could slow the machining process down to be more percise.
We may not get the case for 90 bucks then. They would have
a price like the rest. 150 or more. If ue made a case it would
be more percise but the price would be 300. I don't notice the
hole being off at 60 mph and the body on it.

LOL leroy..

here are a few pics of the tranny.

You can choose between the GPM (CRAPCOUGHCOUGHMOLDEDCOUGH) or the CNC machined FLM.. I would take an FLM over the GPM anyday.

If it works ok and only looks funny, I don't care much. If were bad enough to not fit though, I asked so that someone could warn me before I took the old one apart that it might not fit. If it fits, no big deal. If it doesn't fit, I'm a comin' after y'all!

I have not noticed that problem but I have not yet assembled mine. I was waiting on a replacement idler gear shaft support. The one that came with my trans was bored incorrectly and the shafts did not fit. Now that the replacement part is here I'll check it out.

wow nice polish man...just curious if you do your own polishing I have some stuff to polish and wondering how much it would cost...

I can't say it will fit. I can't say it won't fit.
I can say it will be hard to see. You took the pic from inside the case.
You won't see that on the truck. It is on the bottom as well. The diff cups and chassis will help hide it. As far as looking funny. That would be the least of my worries. Just look at procharger. With all that shine he got you don't notice his. :017:
