What am I?

[Treepep 564]

So,  I got this 4 speed transmission in a lot of miscellaneous tractor parts. Most of them I have traded or sold.  I plan to rebuild and shelf it.  I would like to know what it is so we can get parts.  It moves freely, no shifter.  Oil in it was synthetic and clean.  Garage kept. Just casting numbers 3800 h or n?

 

Thanks in advance for your knowledge!

What size axles does it have, 1" or 1 1/8"?

I don’t think there were any 3 speeds with 1-1/8” axles, were there?

I believe he mentioned it was a four-speed?

5045 used in 953

5047 used in 1054

5051 used in 1054A

5058 used in 1057 and 1257

5059 service replacement for 5045, 5047 and 5051

I believe he told me it was an old four speed?  Not my expertise.  Axles are 1''  I have never rebuilt a transmission and this one seems fine sans the shifter.  I want to go through it and maybe learn something???

 

Thanks folks

oh yeah,  why didn’t I think of those?

I think all of the internals are the same 2 piece 1" axle transmissions. The only difference I know of is the spline shaft had 2 gears that slipped on and were keyed on the early ones and later ones the bottom gear was pressed on but they interchange.

Mike is a little confused.  The spline shaft has the fork gears on it.  Mike is thinking of the cluster gear shaft.  

   The trans is a 3 speed #5007, #5025 to #5053 (depending on what horse it came out of.  I would call it a #5025 until you open it.  The differences would show themselves as 1. size of drain and fill plugs   2. shift rails and how the groves are cut.  Anyway, it is a 3 speed with reverse, uni-drive because of where the brake drum is located...on the mushroom gear 11/44 tooth gear.

The transmission models that GWest listed are 3 speed, but they are considered heavy duty.  Those transmissions all have 1 1/8" axles and the bevel gear differentials.  Treepep's transmission is 1" axles and therefor has the 4 pinion differential.   All 1" axles have 4 pinion differentials.  The 4 speeds have the brake drum on the cluster gear shaft.

"Little confused ? "  More like a lot!  I was picturing the shaft with the woodruff keys in my mind when I typed but my left brain typed spline.  What day is it anyway? What time is dinner?
