The older 'Deere's were axles were easy enough to do. Have no Idea about red painted axles, or later models.

Hah, ya, not much in the way of fancy here.  Building needs quite a bit of work yet and I’m already about 20 grand into it.  Some people on agtalk are daft.  They either think you need a half million dollar shop if you want to change oil in your lawnmower or they think having a $5,000 dollar shack to fix things in is a sinful luxury.

Talking with hired man of BTO one night in the bar.He said they take the tractors to town because the BTO is afraid they might spill some oil on the floor.The shop is fully equipped with tools that are never used.

But he did get in Farm Journal magazine in a article about farm shops.

Update.  After 2 weeks of making hay and corn silage, back to the fun.  First picture is with the bearing carrier housing removed.  The forward and reverse clutches are the top shaft in the rear housing.  Second picture is the forward and reverse clutch shaft assembly.

Do not use open flame to heat bearings for installation. I suspect that is what happened to these two bearings.Attached File  1970D656-234B-4835-A05D-AE3197C53500.jpeg   100.38KB   0 downloads

Looks like maybe somebody did use an open flame on those. I used to do more of that stuff and used a deep fat fryer filled with hydraulic oil. Put the bearings in cool oil with a wire on them so they could be fished out and they got heated evenly and to a set temp.

Back to work on this project. Never did get it finished last year, ran into some problems that needed to be addressed before the transmission got wheeled back together. The worse of the two problems was a worn bore where the MFD output shaft comes out of the transmission housing. Where the bearing cups ride the housing is worn more than .020 over size. Planning to bore the housing to accept a bearing with a bigger cup OD. Need to recut the snap ring grooves also. Not a real expensive deal but going to be time consuming.

Can you get a mobile pin welder guy to drop in to build it up and rebore it?

I suppose but

 

1) why not just cut the bore oversize in the first place as the bearings to do so are readily available and the bore will have to be re cut anyway if it is welded up and

 

2) I’m not sure it will work to weld a bore in an iron housing.

1) I agree mostly but can be a pain in future for someone else to work on with non-standard parts.  Not a huge deal though.

2) Will work but you're right, huge pain to clean/weld oil impregnated cast.

I’ve actually taken a cast housing, chucked it in the lathe, turned it out then used another piece of cast iron to turn a bushing then press the bushing into the original housing with plenty of sleeve lock on it then reinstall the original bearing.
