Yes you could do that but you could not use true GMS gears because the spline in gms gears is bigger than the o.d of the countershaft after the gear is machined off. You would have to use a smaller diameter spline. It also would be tough to cut the new splines because the shaft is case hardened. It would not be hard under the old gear but it would still hard where the cutter would be starting int

Yes I have done a few transmissions this way. I machined off the old countershaft gear. Then I made a new set of wider gears for the top shaft and the countershaft. I pressed these on the shafts and welded them. It worked very well but if you want to change ratios later, you have to machine the weld off and press the gears off and install new ones. Also when you do this, all the teeth on your 7th

No, I have never bored a 466. I haven't had the opportunity to do one yet.

I will bore out the 404 motor to accept 466 sleeves for $400.00. I have done three of them. I don't put the o-ring grooves in the bottom. I just make the bottom bore about .002" smaller than the o.d. of the sleeve. Then put a little sealer around the bottom of the sleeve before pressing it in. I have never had one leak water yet.

I am not positive but I think that the sleeves would be too thin to do this. I don't remeber the o.d. size of a 404 sleeve but they have 4 1/4" bore. A 466 has a 4 9/16 bore so that is 5/16" bigger. You can get sleeves to fit in a 466 to go from the 4 9/16 bore out to 4 3/4 bore and this would indeed give you 504 cu. inches. This is only enlarging the bore by 3/16" and the sleeves are pretty

One thing that you have to watch on these pumps is the direction of rotation. They won't work properly if you try to run them backwards because the relief will be on the inlet side instead of the pressure side. You can convert a pump to the other direction but you have to do some machining so that the relief is mounted on the other side and then you have to plug the old relief hole.

An Autometer tach for a diesel has a pickup probe that can be threaded into a cover on your engine. I mounted one in the front of the timing cover of my buddies john deere 466. I machined eight equally spaced slots in the front of the camshaft timing gear on a cnc mill to trigger the tach pickup. The tach is designed to pickup off of four slots or bolt heads that are going crankshft speed but sin

What I have seen most people do is machine the stock hubs to accept a normal automotive wheel with a chevy bolt pattern. I have done a few of these for pullers.

Steel weighs .2833 pounds per cubic inch.
Weight of 1" dia. x 50" round steel would equal .5 x .5 x 3.14 x 50 x .2833 = 11.1 Lbs
From my experience, tractor axles are case hardened and the usual material for case hardening is 8620 just like gears are made from. 8620 steel does not have enough carbon in it to heat treat so it is carburized first to add more carbon to the outer part of the s

I made a couple sets of gears last year for a small block John Deere with an Urmson transmission. I used to just cut the teeth on a milling machine but it was kind of slow. I just bought a gear hobber so I could make you some gears if you want. I have a small shop here at my house in Salem, Ohio. My number is 330 537 4203.
