brake drum 417-8 update

[troutbum70 858]

The story is that brake drum is even more stubborn than my wife of 46 years, little over a week at it and still have yet to get that bugger to budge. Have tried to brands of penetrates, tried heating and sweating wax into around shaft. My puller is a 2 arm puller, wondering if the purchase of a 3 arm puller would give any advantage?

Doubt it.I get crazy with stuff like this.I was trying to get a truck moved that had a brake that would not let go.Hammer didn't help so out comes the sawsall

Brake drums are a dime a dozen.Protect the shaft but don't worry about the drum.Just me but I would break out the angle grinder.

In your case you need to spray penetrating oil onto the drum while vibrating it with your pneumatic chisel. This is how I loosened the clutch plates in a John Deere model 70 that were rusted in solid.

Ouch!!

 

Well that should tell ya right there that you may need to go to Plan CWS. (Cut with something).

 

Bc has a decent idea too. The extreme vibration of an air hammer and blunt tip on the outside of the drum could help.

 

Patience is your friend if you want to save the drum but like JA I think I'd go to cutting by now too.

Might try all three at one time. Install puller and tension, heat center section of drum, and apply a few wacks with hammer. Not a sledge!

If it is a no go, then I am with JA, good cutting disc on a angle grinder.

Penetrating fluid just makes you fill better, when you have mechanical binding. Rusted parts it may help.

Like magic the vibration from the pneumatic hammer works the penetrating fluid into the hidden rust and washes it out which in turn loosens up the part.

[troutbum70 858]

I have applied tension, heat and 6lb. hammer at same time. Have not considered the pneumatic hammer, so that will be next approach. I leave the puller cranked down on it thinking at some point it may give up and come loose, as a last resort I will attempt cutting.

I believe it's a good idea to leave the puller on there all the time.

You are most certainly headed the right direction.

It's about 99% likely that it would eventually come off given enough patience. It's just a matter of the ratio of Need for tractor vs that same patience.

No hurry I do have a good bit of yard clean up pending, but my commando 800 can tote the yard wagon around for that. 

[JoeM 8,450]

One other thing that may work is if there is a little end play in the shaft. Might be able to drive a couple wedges behind the drum and tap the shaft inward to break it free. ???

[squonk 43,962]

Put tension on the pulley with the puller and apply heat at the same time.

[troutbum70 858]

Well finally got this bugger off, but as you can see I really beat the tar out of it and cracked it as well. I have another 417 but it sits way out in the back and no way easy to move it so not sure if I can get the drum off it. Any one have any idea if new ones are available or if only finding a used one.

[JoeM 8,450]

I would give that used on a try. I know this one was tough but I have seen them when I thought they would not come off, they slide right off. Used in good condition is good too.

I would take that old one and drive a nail through it into the shop walk............kind of like a trophy!

[ebinmaine 73,037]

Yeah like Joe said... A good used one is perfectly fine.

Post an in the wanted section of the classifieds or just call Lincoln at A to Z. He'll have one.

 

[troutbum70 858]

Well I have to check the other 417 as it is a hydro tractor so not sure if it is the same drum as the 8 speed, I know the brake bands themselves are different as how they mount. I have a fellow about 25 miles away that used to be a wheel horse dealer and he has a few things around along with some old tractors.

[stevasaurus 23,307]

That is one heck of a paper weight !!    That could be a calendar shot.    Go to A-Z and get a used one.

I have a chassis out back and went back there today with a 6 foot pry bar and the one on that tractor after fourth try with pry bar it slid right off, as you can see from the picture the one on my running tractor put up a true fight. Fer sure when the replacement goes on it will a good coating of rust preventive.

That's probably great stuff, I have anti-seize marketed by caterpillar several years ago. I have had very good luck with it on my 18 wheelers, my truck was almost as old as my wh 417 and there wasn't a nut or bolt that couldn't be readily be taken off with the hand tools I carried on the truck. Off which some of course required the 3/4 drive. I probably have more than I will use up now as I sold the truck and all and retired a couple years ago, a little bit of the stuff goes a long way. I have no idea who would have produced the stuff for caterpillar. I did notice the product you provided a picture of has a very high temp resistance, not sure if what I have would hold up to that temp.

Congrats on getting that sucka off!

 

Did the caterpillar stuff end-up everywhere like Permatex?

 

[troutbum70 858]

Well I suppose if one mishandled it, then it could be easily worn. But its like the old hair cream back in the day, ya know a little dab will do ya hi hi. My complaint with Permatex has always been its packaging, back in the day of using it my dad and I would open a new container scrape the applicator clean as much as possible back into container, then give the applicator a good gas bath, cut the applicator free from the lid and keep the applicator in a little bit of kerosene to prevent drying out then we could get a dab on the brush and apply with no mess and put the applicator back in our separate little jar. Way back then I think Permatex is all there was and before that everything got a little axle grease before going back together.
