winch drive shaft

[clinto]

Ok, here are some better pictures.


I think first I am going to try and shift the winch over. If that doesn't work, it's grinding time.

What if the rear motor mounts were off slightly or weak and leaning to that side. Maybe even a squished out front mount could add to this issue. Just a thought.

It seems as if the steering box is at an angle.

If you shift the winch will the shaft hit the engine mount?

 

[gimpyrobb]

The spacing looks even along the motor mount. I'd look into the steering box first!

I glanced at them last night and they appeared fine.

I think it's the angle I shot the picture. Compared it to my other trucks last night and it looked the same.

I don't think so but you will see it soon. I believe I am going to try and shift the winch over, per Gringeltaube's suggestion, then I will clearance the steering box if that's unsuccessful.

I have had the same problem since i put a winch on my m35a2c. it was from the air force as well. The winch came off a m35a2 unsure on the date and engine but i would say it was multi fuel. I have used mine like it was but not very much. I may try to grind the cover. Unsure as to what i am going to do.

will shifting the winch just push the frame rails apart?

The idea is that the tolerances in all of the bolt holes give some adjustability. Loosen everything up, shift the winch over, re-tighten. Frame rails stay where they are and hopefully the winch shifts over just enough to clear the box. Doesn't have to be much.

I hope you have more room than I did. It was hard to squeeze my winch into the frame rails when I did mine.

Had to push the rails apart about 1/16" or 1/32" with the hi-lift to get the extensions in. Was right at the ragged edge of fitting. Once the extensions were in, we still had to pull them in the rest of the way with the hi-lift on one side and the come-along on the other side.

See pics.

AH, I had everything on but the winch. I dropped it into the frame rails with my motor hoist. What a pita. Took a 10lb hammer to "love tap" her into place. Yes wood blocks were used to lighten the blows.

Clint: your brackets /frame extensions are of the "welded" version.
To gain clearance you (and others) may consider this other option before touching the steering box.....

Sooo, did it shift?.... how did it turn out....?

Going to mess with it this week-simply ran out of time last week, but luckily did not need it Saturday.

 

[gringeltaube]

OK, good luck then!

So I got some time to mess with this today, after I finished parting out one of our parts trucks (http://www.steelsoldiers.com/conversations/87435-lot-work.html).

I had pulled the front bumper off to put the tan bumper back on and I figured as long as I was doing this, I'd loosen up all the frame mount bolts and try shifting the winch over.

Attached a chain to winch
Wrapped a chain around a tree
Positioned truck
Hooked up 2 ton chainfall and proceeded to "pull" the winch toward the passenger side.

See pics for more explanation.

Outcome:

Beginning: Driveshaft touching steering box

All bolts loose and winch under tension from chainfall: Clearance was approximately .110"

Winch still under tension but all bolts retightended: Clearance was approximately .065"

Bolts tightended and chainfall removed: Clearance was about .030"

Looks like the winch is pretty much where it wants to be. Not only did I smack both brackets with a BIG hammer to try and move them over while they were under a load, but I had a lot of load on the winch, pulled it to the passenger side. I actually slid the whole truck about an inch towards the tree!

So at this point, I've moved the winch over as far as I can and I am still too close for my comfort. I can get the driveshaft to touch the steering box by grabbing it, due to play in the yoke where the sheer pin goes.

So I will be clearancing the box or building a smaller driveshaft.

You can't see the issue, can you? That pass side bracket is on wrong.

 

[Tinwoodsman]

Hope you never have to remove that thing Clinto!

I can't see anything wrong with it. Wondering what you found...?
