Ever Used An Air Wrench To Remove Swingarm?

[cccpastorjack]

I have read all the posts on trying to remove the swingarm pivot bolt and how tough that can be. Some even suggested using a 4-foot pipe as an extension on a 3/4 inch pullbar. QUESTION: Has anyone ever tried using an air wrench to "zap" them off?

Also, the manual does not describe (or even call for) "phasing" the drive shaft. Many in the threads said they know the procedure for marking and doing this. Anyone who would share that procedure?

Thanks so much!

I don't think I would do that. Where have you been? You missed kevincook's great post on swing arm removal (title is "slave drilling procedure"). Just one page back in time. Give it a read.

I tried the air wrench, no joy to break it loose. Also it was ok to help put the swing arm back on .but not to torque it.
I've had mine off for the slave valve and clutch replacement and there is nothing better than an 6 foot piece of pipe.

Jack,

This post might help you out. I'm going to updated it with some suggestions I have received but they are pretty minor.

A standard impact wrench may or may not help, I've had mixed luck. You'll need a heavy duty unit and a good air supply. If you don't have that it's the old breaker bar. Use a heavy duty one, perhaps a 3/4" drive with a 1/2" adaptor, it can take an amazing amount of effort to break the pivot pins loose ( may take a 4 foot pipe to get the leverage needed). It's worse if loctite has been used.

I keep hearing about this pipe thing . I have only had two off, one was a "sweat popper" , the other not a big deal.
Guess I'll get a "cheater pipe" for the next one (just in case).

I only weigh 150. the pipe helps so I don't have to hurt myself. 27 years of working on helicopters has taught me a few lessons,

I found that a good impact gun works the best on removal.
My first removal with pipe and breaker bar ended up with stripped pivot pin trying to remove differential.
Had to remove swingarm and take to machine shop to drill out and retap. the other pins came out just fine with a MAC Tools impact wrench.
Does anyone know what metal is used for pivot pins, I tried to torch pin but was not able get hot enough ?

I was just wondering why it wouldn't work for removal only of course. I have a Snap On Air Wrench that applies 650 ft lbs of torque in reverse, so I was just wondering why it couldn't be used and it would seem that it should just take it right off. We'll seeeee...sure don't wanna round that sucker! :eek:

If you have 650 lbs in reverse that should do the job. Mine can reach that but my big compressor needs a new motor, the smaller one can't provide enough air.
