Clocking down a 208???? (Flame suit on)

slytowncrawler2 · May 3, 2015

Have a customer. He is trying to make the local bogg this weekend to blow off some steam with the kids.
He has a Muncie and 205 but we are not ready to swap in yet...... I planned on clocking his case down to help with front shaft bind, so he can go splash through the mud this weekend an have a good time. I have never done this before either up or down ... My question is. Is this as simple as pulling case an dropping a bolt hole??? I'm sure the case won't receive oil properly and the linkage will be off. Again this is for this weekend or until we can do Muncie an 205 swap. Thanks again for any input

I don't know anything about the mounting pattern of a 208 but if it had a round pattern and can be clocked turn it down and ride out won't hurt anything!

Kinda wat I'm hopin for allonetonyota. Just a "get me by" till the good stuff goes in.

We done it for a friend of mine. Believe it was the same clocking ring as a Dana 300. Worked fine.I have an extra one if interested.

So I do have to have a clocking ring throttle junkie???? For some reason I was thinking the holes would line up. Thought heard that before

throttlejunkie · May 3, 2015

Seems like the bolts were evenly spaced, if I remember correctly. But, seems like when we rotated to the next bolt it rotated it way to far. Its been a while back so maybe that's correct. We wanted it flat and that clocking ring was the only way we found to make it happen.
As far as toughness of the case, he ran his with rockwells and 46's. Held up pretty good, but not a bouncer.

No ring required for a round pattern. The ring just gives you more adjustments instead of clocking it an entire stud/hole.

throttlejunkie · May 3, 2015

Doesn't send the case higher than flat?

FlatlandFSJ · May 3, 2015

Oh, it'll send it up into the floor if you're clocking it up. Hes trying to clock it down for a mudtoy, dropping it an entire hole shouldn't be to much a problem on some thing like that.

In our case it's a tall mud truck and we are bringing it down so one whole bolt hole down wouldn't hurt (I'm hoping)

Gotcha, I'm almost positive that the six bolt pattern on all transfer cases are asymmetrical, could be wrong. I can check mine in the am

No flame suit required on hardline.

slytowncrawler2 · May 3, 2015

Lol eddy I wasn't sure how dumb a question I was askin. Fig somebody on here would know tho. Thanks for the input guys

Ill measure, but as far as I know, and always heard the round pattern before '91 is the same.

I'm with you on this but I think they are close enough to where one or two holes can be wallowed out to be made to work.

This is what I had to do on an Atlas a long time ago to clock it up one bolt hole using the NP208 adapter on a TH350:

If its just for one weekend I would be inclined just skip that one bolt so long as the case doesn't leak through it.

throttlejunkie · May 3, 2015

Bingo, there ya go.

al1tonyota · May 3, 2015

I'd run it till it broke!

Don't 208s have chains? Meaning if they get too vertical or upside down that the bearings will get dry? Or is that just for 231s,241s, etc?

Yes they are chain drive but it'll sling enough oil up for offroad use! The chain will stretch or the case will break before it hurts the bearings from low oil volume.
