Vtwin Ford Race Mower

Picked up this Ford for a race mower and just got a welder so I started tearing it down. I dropped the tansaxle but I cant find a model number on it anywhere. I want to get some new seals and bearings and see if I can gear it up. Just says Patent 4.103.566 and re 32.125

Look next to the small round disc the brake there should be a small plate about a inch long sounds like a cool build u got anymore pics

Im guessing its a 800 series peerless

Not much going on with it yet but this is the frame. I plan on doing direct steering and all new tie rods. For now I'm focusing on the transaxle.

that one is an 801, i had the same one in my lawn mower trike. BUT i had found out that it spins counter clock wise. as in the motor would turn like how it normally dose but the input gear is on the opposite side of the case. you would have 5 gears in revers and one in forward. you can still use that trans but you would have to flip or cross your belt or if you mount it backwards.

Is the highest gear next to neutral? Or what? I imagine switch some gears around an it would be normal.

I have the same mower and it worked like a normal transaxle, before I screwed it up...
*edit: and it was an 801

I have 2 of those trans but not sure what thay are. Im speeding mine up internaly for a project. Pritty easy just have to do some machining and welding.

Could you go into detail what I would have to do I'll be taking the tranny apart this weekend and locking it but I also want to speed it up.

to speed it up, just change the pullies. big on the engine, small on the transmission. how fast are you looking to go?

I could but I figured I could keep bigger pulleys and get better belt grip. I'm looking to go 40 with it and I'm not sure how big of a swap that would require.

Yea I've seen em its actually the same tractor I have I just thought this transaxle was oil filled because of the plug on top. He's not clear exactly what he does to it. I'll just pm him on YouTube. I'm gonna be taking it apart this weekend most likely Sunday.

Stretch has a video of how to speed a peerless 920-930 up basicly the same thing. Just used parts out of the other trans. Here is link to video

If you do a 3' pull on the transaxle and a 4.5 that will give you 13mph in 1st gear, 26mph in 2nd, 39mph in 3rd, 52mph in 4th, 65mph in 5th, and then a massive 78mph in 6th. But really who would want to go that fast with no windshield

There is much more then a windshield if be worrying about at 65 from cutting grass to that.

How do you figure that. Im running a 5 on trans a 6 on motor and 26 in tires and only get 30 with no governer. Thats basicly running a 3 on trans an 4 on motor i dont think a 1/2" on pulley will make that much diffrence.

It's a exel that someone created on here. You put in engine rpm then each pully size and it calculates the speeds you will aproxomatly get in each gear. I will see if I can find it and I'll put a link in here.

My mud mower runs about a 1:1 ratio and goes about 14 but it's got some belt slippage in the higher gears so that's why I wanted to gear this up internally. I have a parts tranny I can take gears out of. I watched stretch's vid I could just gear up the final drive ratio like that with the parts and pulley swap from there.

So I got the transaxle at my house and started working.

Found this.

I can't get the innards from the top half of the case because the shift key holds it in place. I assume this washer is supposed to come off but I can't get it to budge and I just hit the shaft down.


This is the motor I'm using btw it's a 14hp vanguard from my mtd that blew a tranny.

Why the picture of the exploded fnr?

I had it so I figure I'd show everyone

I got the washer off and shift key out I had to grind the outside of it down because when I hit it in I flattened the end to where the washer wouldn't slide off. I think I found a way I can use my spare gear sets like stretch did I'll post pics in the next few days of what I have planned for now it's soaking in some degreaser.

Just got done welding up the spider gears in this thing. Was a little different becasue of the way its set up. I don't know if I can speed it up with the gears I have though because they're out of a spicer and won't fit easily. I don't have a lathe to bore them out. I'm pretty sure 3dmachines just used parts from the transaxle but he hasn't answered me. The only thing I can think of is that he used the reverse gear to run the gears because he said it ran backwards and was hard to turn after because the chain was worn into the direction it usually goes. He also says the tractor has N12345N for gears and apparently no reverse. I'll take a look at that tomorrow. Has anyone pulley swapped a tranny to do like 40 or 45? It is gonna be running some big tires.
