Tim’s payloader and generator BS thread

Tim, Case/NH and Agco have used some ZF stuff for MFWD front axles through the years. Even the first 50 series Deere mechanical were ZF till JD started building their own.

A trip to All States Ag Parts or if they still have anything left up at Larsen's in Cambridge might turn up something that used the same hub/planetary?
Thanks. I've been searching by part number and have seen some of those applications listed for common items like seals and bearings. I've ordered wheel bearings by bearing number and seals by dimension. The prices were half of what was originally quoted. I found to a re-seller in Germany with decent prices on the gears. I've sent a request to purchase. they don't list U.S.A. as a customer address option. I hope they aren't restricted from selling in this territory.
 
and with that damage all of it needs replaced. was there even an axle in it? may be cheaper to find a whole used take out rear?

I agree with Mike, unless you're gonna completely tear down that axle and clean the shit out of everything, the shavings have probably gotten places they shouldn't be.

Of course if this if a flipper machine, it might not matter but I'd still want to do it right.

Cross contamination is possible even though the hubs are somewhat isolated from the center. I'll be checking the center oil for metal contamination. I plan on checking the fronts too before I place the big parts order. The bearings and seals ordered will allow me to put in together and seal it up, move it around without causing more damage. It may take a while to find a used assembly.

I know a guy in Germany that may be able to forward some parts if you don't have any options.
He owes me lots of favors ,he is a wanabe goldminer and leaves his truck and junk at my place.

yeah i would at least rinse the pot with fuel. but what i was gettin at is any gears that APPEAR to be ok. btdt, with that kind of damage i wouldnt reuse any thing in that hub. i left the ring gear once since it looked fine, took out another set of planets in a week. that ring gear had a hair line crack you couldnt see on the front. it would open slightly when the machine reversed and allow misalignment.
 
Update.
I checked the center diff, it only had a few ounces of oil in it and the drain plug was loose. Otherwise it looks good.
The wheel bearings arrived today and seal should arrive early next week. The wheel bearings were $262 shipped from UK for qty 2. They are Timken, same as the original but 1/2 the price.
I have a quote on genuine ZF parts from a company in Germany. Their prices are 1/4th the price quoted locally. That is after accounting for shipping from Germany. New ingnition switch arrived and gas springs for the hood are ordered.
 
I got the new races installed. The scoring is cosmetic. There is still just enough material supporting the bearing race. It looked worse. I had cleaned it up on the lathe. I stoned the mating surfaces. It had bits of bearing and gear imbedded in it from when it was slapped together. It was too hard to file flat. This hub is the only part being re-used.

Tim, question; i am about to build a new fairlead roller, its nothing but a 12" section of heavy wall 8"DOM tube with 2" thick ends welded in. i will have to have a machine shop bore the bushing bores accurate. should i have them bore the holes before or after i weld it together?
i can compensate a tiny bit for misalignment during welding by using a length of stock.
the only two around that will mess with a small job like this are so busy, i am hoping they can do the boring quickly as opposed to doing the whole thing.

Who machined the end caps?
 
thanks Tim, my thoughts exactly. and damn, thats about the worst i have ever seen, and i have seen a few. the 70s franklin loggers had small rockwells with brass planet axles, they would wear and spin in the housings. usually when misalignment happened it made a mess, but that there is by far the worst. my redneck way was a fuel rinse from an electric transfer pump through the open axle housing. shhh, dont tell the epa.

Maybe have the machine shop square up the tubing ends and cut a step the round disc ends? If they are boring the ends, it wouldn't take much more time to cut a step. Then all you gotta do is clamp and weld.
yes sir, i had already thought of that. quick on a lathe, save me a lot of grinding to have them cut a steep chamfer on one side.
 
The wheel bearings are a tight fit on the spindle. The service manual instructs to heat the bearing, set in the hub, install the seal and then install assembly onto spindle before it cools down. I've never had things go smoothly when doing this stuff. I cobbled up something to help.
