Front axle spindle - what models interchange?

Recommended Posts

pacer

Am rebuilding my 414-8 steering - whew was it loosey goosey! - have got everything covered except right front spindle. No doubt several other models will interchange so I was hoping somebody here could give an example/s of other models.... In case you can read the dims -- wheel shaft is 3/4 x 4-1/4" and axle is 3/4x3-1/4" You CAN see how mangled it is!

 

And yes, Im gonna put thin is wanted too, but was curious as to what other models would fit.

Any 300 or 400 series with the same size front tires would work.

110212 spindle has been replaced by 115426. Shows a very poor representation of what models used it.

Good picture of the taller spindle used on some of the 300-Series that used the smaller tires and wheels.

To the rescue again Garry, using that part # I found an NOS one on the bay for a good price! so will get it ordered up and all the steering will be nice and tight again!

 

Thank you!

Might want to check the axle itself , probably ground down pretty badly from the looks of that spindle wear . I generally sleeve all of mine - spreads the load out better and stops the wear issue .

Yeah, that what Ive been doing as I go along - have rebuilt the fan gear and its mount and the shaft. Have to custom make most of the sleeves/bushings as both parts will be worn - the shafts below the 3/4" and the sockets over, so thank goodness for a lathe/mill! or I would be searching for all those pieces! But the spindle is different, I dont know of any easy way to fix it....

I've discussed those spindles with several welding/fab shops and the consensus is the same - they are probably heat treated steel rod stock after bending the shape in a die press . Building new ones would be a real pain and require a lot of setup work to get the angles dead correct - if it were off even slightly it would show easily and wear the front tires in a hurry . They could be welded up and re-turned in a 4-jaw lathe chuck , but it would be a really tricky process since it's not a 90* angle . Other option to to use to separate pieces of round stock and a machined block in the middle with the correct calculated angles - but there are a lot of differences in the different models of tractors and their front axles . The D-180 I have , for instance , actually has a 2* negative rake to the rear stock and the 18* spindle angle - would be interesting to make a block like that on a mill but I don't have the knowledge/experience at mill work myself . If the blocks could be made and use 4140 round stock you'd have a seriously strong spindle - I'd also consider at the same time doing some upgrades to the axle for full length bushings and bottom support bearings for all the variations - that would make them last forever if they are kept greased even occasionally .

 

The way I rebuilt the Ross steering box and front axle on my D made it steer as good or better than power steering - even with fairly sticky v-bar front tires on concrete you can spin the wheel with one finger - well worth the time and investment in tools . Someone really needs to take the reigns and get something in the works for new spindles - they are becoming quite limited in supply and some are nearly impossible to find even used for restoring these old machines . If someone could make the machined parts I can handle the welding of the exotic alloy here with the tig and required filler rod - I keep a pretty good assortment for those types of alloys . The truly hard part is figuring out the correct angles - almost every axle/tractor has a lot of wear on it from age and calculating those angles off the center pin in the axle isn't easy - at least with what I have here for tools . I suspect there are probably 20 different variations if you only go back to the early 60's - that's quite a task...
