Post by: tel on August 07, 2012, 10:28:48 AM
Just when I thought I might start getting a bit of workshop time in my neighbor comes up with this little problem.

Don't worry, Tel will fix it :zap:

A bit of chewing gum, loctite and superglue and it will be back again on four wheels in no time.

I used to get jobs like that, I call them 'just' jobs.

"Can you just fix this for me." :hammerbash:

It's the first MF65 I've ever seen break an axle - and finding a replacement half shaft is going to be the tricky bit. I think I can repair most of the mangled 3 point linkage.  :(

Thinking positively: at least its not in the UK other wise it would have also been up to its axles in mud.

Was this a low-budget privateer attempt to emulate Nasa, by any chance? If so, I'd recommend bigger parachutes...  8)

What is that thing on the back of it?....is that a home built dozer blade? :hellno:

I trust you have another tractor to pull that one out with.......changing an axle in the dirt bank isn't going to be any fun......

I'd look at the outboard bearing mounts very carefully...as well as the axle seal seats......if the shaft is twisted....that's going to really suck getting apart.

Not familiar with that tractor. but I trust the outboard bearing housing is seperate from the axle housing.....you got a hope then.

Yeah Dave, getting 'er out of the gully was Sunday's job - towed out OK with another MF once we got a log set up as a skid over the front axle and under the rear one, then pulled it up level with the other MF and chocked it all up to a workable height. The bearing housing is separate to the axle housing proper - probably 12 or 14 bolts to undo around 'er.  Don't think there'll be any real trouble pulling the shaft but you never know til you get in there a bit.

It's a very similar set up to this 'un.

Got it in one - and the cause of all the trouble, whoever built it made the links too short so it only just clears the rear tyres - coming up out of the gully it picked up the tyre, which pulled it up pretty near to the top of the wheel before the wheel stopped and the axle kept going. Smashed up all the r/h side of the 3PL in the process.  :( I gotta get an indoor hobby!

Gee tel,

I thought it was a carry all that had tangled up with the wheel, if it's raining your way like it is here, I'm glad it's you - not me.

What is with us guys ?

I didn't take any photos but last weeks job was a forklift side shift support bar. Your average shipping container has a tare around 3000kg. My partner's son thought he could hook one fork under the corner and side shift it into place with a 1.5 ton forklift. He did manage to side shift the forklift up to the point where the support bar gave way. 2" x 1/2" cast steel bar with guides and locking hooks. Snapped it off about 1/3 of the length which is around 2' 6"

First lift off the forks, easy enough, then lift of the carrier frame, bloody heavy, then an overall covering of us and the surrounding area in diabolic oil to remove the ram and finally the side shift bar fell off in its' two pieces.

Did I ever tell, no pun intended, how much I hate welding cast steel. Much faffing about with a blow lamp to preheat it then a couple of tacks, then checking for square with my asbestos rule and fingers finally grooving and welding. Fag time while it cooled then put it all back. All up a bit under 3 hours.

The impossible we do immediately, for miracles wait 10 mins.

I suppose I should be grateful at least I was inside on a concrete floor.



Best Regards
Bob

Hmmm indeed,

If it's one of the later models maybe a broken ring gear/planetary housing or if your real lucky both :hammerbash:

Onya Bob - cheer me up why don't you? That glass of black is lookin' better by the minute.

The good news is I've found an axle - $220+ freight.

Well, the bit is out, wasn't too bad in the end and looks like all the damage has been confined to the outer axle.  :NotWorthy:

Last one is a good shot that shows the heat treatment of the part leaving a soft core

tel,

I'm glad for you that the damage was confined to the short axle and no deeper into the diff. I must admit I had visions of bigger and more involved problems.

Best Regards
