Well you should have seen my brother Frank over this past month. At one point I walk into the shop and he says to me *&^%$ you! What did I do this time I ask. Well not you, just this *&^%$ truck!
Around Christmas I posted an item about his a broken 230 bell housing. The left ear broke off.
He has (mine actually) a poly 318 rebuilt brand new ready to go in. But not enough time before the 2010 Vermont Rally (you coming this time? Matt Lane from Ontario may be able to bring you.) to sort out gearbox, BH etc. That's another question for you guys.
So he gets a 230 bell as a loaner to make sure he has a running truck for the rally. So installs no prob except he's bummed about the work involved because within a year it's all coming out anyway.
He has had probs with a stuck clutch. He sees a raised ring in the inner diam of the clutch that looks like it the inner diam is smaller than the flywheel inner diam and that is apparently what hangs up.
This is a military t245 installed in a wdx using the wdx bh but the military np420 (not sure about early/late military np420).
So he goes upstairs to look at the pile of extra clutches we've accumulated (like all piles we can't remember where they came from). Finds a better looking clutch and installs that. I don't know if he checked the diameter of the clutch to compare to other clutch or flywheel.
Anyway, time to install gear box and will not go in. Of course do not have a clutch alignment tool so he figures that's his trouble. Plus the gear box has a pto hanging off it so it's tough to wrestle with.
Now it's cold as hell, late and time to go home. I remember that I have an input shaft in a box at home, I can bring that next time for an alignment tool. (In a box, shipped back to me from Charles Garbee years ago, I loaned it to him, he returned, don't remember why, something about making a new shaft with diff splines, must have been a repower project, should get the specs on what he did, might help here.)
So next week, I give Frank the shaft (pun intended?) I go skiing in a recent blizzard which was great, come back and he swears at me, one for skiing instead of working with him and because the gear box is still not installed.
He figures out that the clutch is too small for the input shaft on the gear box. Diff is small enough that you would need a caliper to measure. 10 splines, just a smidgen too small. But big enough for the C. Garbee's extra shaft.
Go back to the pile, get another clutch, and the shaft opening on that is way too big. All of these clutches came out of PW's. So finally he gets a grinder out and grinds down the ridge on the original clutch so it wont hang up anymore.
Don't ask about grinding clutch ridges down and resulting dust. He was smoking a cig at the time so maybe that offset the dangers of clutch dust. The clutch only has to last the 10-15 miles he'll drive at the rally so he hopes he has enough clutch left.
So now let's discuss poly 318 early/late bell houses, what gear box goes with what, and are there pto's made of unobtanium available for the later gearboxes.
