ri702bill 8,281 #76 Posted May 19, 2022 (edited) @dmoore@Handy Don I have no clue - that is not my tractor, just the HY2 unit is...I have a 6-12 set similar to that and they are Firestone Town & Country "snow tires" I believe that Miller Tire sells a reproduction version, but you better have deep pockets to buy them ...

Handy Don 12,128 #77 Posted May 19, 2022 (edited) I have these very similar BF Goodrich Silvertowns 6-12 that I'll be using. They are also pretty nice but not quite as detailed a tread. Harder rubber than snow tires, IMHO. Edited May 19, 2022 by Handy Don 5 1 Share this post Link to post Share on other sites

ebinmaine 67,234 #79 Posted May 19, 2022 Remember that the definition of a snow tire has changed a little bit over the last 60 years and also that those tires are aged which rubber harder. 4 Share this post Link to post Share on other sites

Trina has a set here that were removed from a (('67??)). Look decent. We'll check 'em for weathering and re-home them. 3 Share this post Link to post Share on other sites
dmoore 773 #83 Posted May 20, 2022 So I decided to do a little more disassembly today. I was curious what the trans oil looked like. I got my answer Share this post Link to post Share on other sites

dmoore 773 #88 Posted May 22, 2022 And crystal clear. The tractor was inside for a long time. It got caught in a deluge being transported to me. A couple of gear oil flushes and it will be good as new. During the short run after getting it started it shifted and rode fine. Indestructible. 3 Share this post Link to post Share on other sites
dmoore 773 #89 Posted May 22, 2022 20220522_191921.heicFilnally got a chance to disassemble the old 854 today. Everything came apart perfectly. Now to media blast it all and get it in etch primer. 3 Share this post Link to post Share on other sites
dmoore 773 #90 Posted May 23, 2022 So while tearing down this lil tractor I noticed there were 2 roll pins securing the steering arm to the spindle. At first I was baffled. Then I looked at the parts breakdown and sure enough, there they were. A 1/4 & 5/16 roll pin. Anyone know why?? Share this post Link to post Share on other sites
oliver2-44 9,678 #91 Posted May 23, 2022 Sometimes WH put one roll pin inside another ….possible for increased shear strength. 6 Share this post Link to post Share on other sites

Also so that shear forces could not compress the outer roll pin (they are hollow, after all). Compression would permit movement of the joint. 3 Share this post Link to post Share on other sites

ri702bill 8,281 #96 Posted May 23, 2022 The pin inside a pin is sometimes seen on the lower steering shaft to hold the sector gear - you need excellent shear resistance there. I have had good success replacing the 2 pin setup with the proper size & length coiled pin (aka Spirol Pin). 3 1 Share this post Link to post Share on other sites
ri702bill 8,281 #97 Posted May 23, 2022 (edited) The frame looks nice and straight. How are the 4 Unidrive holes - any cracks? What about play or wear in the clutch shaft thru the frame - it is steel on steel, no bushings unless you add them.

ri702bill 8,281 #98 Posted May 23, 2022 What about excessive play in the front axle / spindles?? Both worn axle bores and worn spindles can be fixed - the axle can be drilled and reamed for bronze bushings; the spindles can have worn areas welded to build up material and finish shape them. Had to do both on the 502. 1 Share this post Link to post Share on other sites

Actually they are a 5/32" inside a 1/4" unless someone drilled them out. I didn't realize they showed the two of them on the parts list until just now. I had some slop on the left side of my 854 and just a few days I replaced the pins. There was only a 1/4" in each side. I did the double thing. 2 Share this post Link to post Share on other sites
