Identify transmission

[Jennifer 1,877]

Ok so hopefully someone can shed some light on this for us!  The black transmission has brake drum in different location then the other!  What tractor is it for?  Please identify!

@stevasaurus would probably know 

[The Tuul Crib 7,337]

Are they the same transmission? One is black and one is red.

[rjg854 11,491]

They are different, notice the location of the brake drum.

The black one would have been used on later model two pedal tractors such as a B80 for example.

      ebinmaine is correct. The red one is same as my 3 speed '67 Lawn Ranger which only uses one pedal.

That's how the ones are on the 1966 and 67 models we have here.

 

The black one shown above matches my 1973 and 74 Transmissions.

Ok that’s definitely a learning curve!

This was a curve I learned the hard way last fall when I was trying to get an 8-speed transmission to work in a 1267 which would have originally had a six-speed. given the different locations of the brake drums, you can see that the linkage would be a little bit different to operate them. The previous owner had tried to compensate for this by putting a slight bend in the original rod and leaving the adjustment all the way out. It was headed the right direction but did not work. I fiddled with it for at least a month and tried several different linkages and rods and experimented quite a bit but I never quite got it right.

The tractor was at a point where it would run and drive and it probably would have been okay for doing things like hauling heavy loads but not so much for things that need the clutch to be engaged or the brake to be used, often.

 

It was a great experiment and I learned a lot and I don't regret one second of doing it although it was frustrating at times. I stopped trying to get it to work because we got the cinnamon horse finished up and I really prefer a tractor with two pedals.

The two pedals thing can be a real benifit

on a hillside for sure!

Yeah. That's why I like them.

Also the ability to keep my feet flat on the steps/boards.

I'm not a fan of stirrups for working tractors.

Please explain the two pedals referred ???

[Jennifer 1,877]

The red transmission was in the 702 just got but it  failed and had to replace it with one out of the 552!  They was the same!  But the black one was said to have been the original to the tractor start....  however because of the brake drum placement I could not mount and use!  

[ebinmaine 68,390]

Correct.

It isn't original to an early 60s tractor.

On Trina's 1967 tractors there is only one foot pedal which operates both clutch and brake... Like your own.

 

Starting around 1973 or 74 Wheelhorse began putting the brake pedal, as a separate pedal from the clutch pedal.

Clutch on the left. Brake on the right.

@Jennifer, the transmission in your 702 and your 552 is a #5025 if it is still factory.  The brake drum is on the mushroom gear shaft.  The black transmission has the brake drum on the cluster gear shaft and is considered a 4 speed...probably a #5080, but could also be a #5084 or #5085.  They were used in the Work horse and Commando 800 and the B-80s.  One other thing that you will find different then your #5025s, is the length of the axles.  The black trans will have longer axles because of the fenders the Work horse and Commandos used.

 

You could use the black trans on your 702, but you would have to modify the linkage a little.  Depending on what is wrong with your 5025, most of the parts in the black trans are inter-changeable.  Your 702 transmission is almost always fixable, so do not throw it away.  Open it up and take some pictures... 

 

You could make your black 4 speed trans a #5025 trans 3 speed by simply taking the #5025 cluster gear and shaft, the mushroom gear and change out the axles if you want the shorter axles in the differential. Those 2 holes in the transmissions are the same size, it is a matter of just changing out the bearings to the other holes...and then your brake drum is back where you want it. 

 

Here is the thread for re-building your black trans...it also works for your other 2 transmissions.

Most informative yet!!!  Thanks ever so much!!  Will adventure into opening up transmission later down the road!  Thanks for the info!!
