Converting MTD FNR transaxle for racing
Details on how I convert the MTD FNR transaxle and make it usable for mower racing.
Parts list:
3/4" keyed axle shaft
5/8" keyed axle shaft
3/4" shaft lock collars (2)
5/8" shaft lock collar
1203 12 2RS bearings (2)
1/4" keyway stock
#40 sprockets w/ 3/4" and 5/8" hubs
#40 chain w/ master link
3/4" and 5/8" thrust washers
Note* THIS REAR IS A "717" MODEL, WHICH HAS THE SPOT CUT OUT FOR THE BEARINGS, THE OTHER FNR MODELS LIKE THE "719" ARE THE SAME EXCEPT THEY DO NOT HAVE THE CUT OUT FOR BEARINGS. THERE ARE SONE DIFFERENCES IN INPUT SHAFTS ON SOME MODELS AS WELL. BUT OTHERWISE CAN BE BUILT THE SAME.

Can I purchase one from you ready to go?
How do you get your tires to stay on I am doing the same thing
I’m having trouble figuring out what I need anyway I can get in contact with you to maybe put a cart together for me on what I would need
Same here I’m just looking at the princess auto catalog today n I can’t seem to figure out the sprockets n in the pictures they don’t look like the ones in the video at all can PEi let us please know like all part numbers etc or are the sprockets need to be welded on to the weld-on hubs bc there’s different like are you PEi guy in video ment to say weld on hub and weld on sprockets or do they already come as a one peace ya know what I’m saying here also what does a thrush washer look like ???? 2:03
Nvm about the sprockets I just figured that out after I said that comment now I’m only stuck on thrust washers so the sprockets n weld on hubs do need to be welded together first other then the thrust washers I have everything else figured out also how many of the thrust washers we need ??
Did you change the input shaft from a splined to a keyed shaft? I am trying to figure out how to do that right now. Thanks.

Great video. But why remove the reverse gear. Only thing I can think of is it may prevent it from jumping out of gear.
Everything I've seen about these trans, everyone says they are junk, and on all the other builds, they always say get away from the chain it is a bomb waiting to go off. I have 2 of these I was going to use, but now am very curious. How did this hold up? And what would you do differently?
Hi where can you buy the kit
Could this handle a direct shaft drive from a motorcycle engine it will only have 25hp but im trying to eliminate any belts or chains its for a mini rat rod build 👍🏻
Awesome video! I wish there was a bigger community of people like you who share their knowledge. That is how different race specs go to die. Thanks for this!
Buenas donde se puede comprar ese kit
Oh I see you caught a keyway into the locking collar from the travel reverser
Is that input shaft stock? Because mine has splines on it
How do you get a keyway on the small sprocket
I'm going to do something similar but I'm going to keep the travel reverser I'm just building up a fun go-kart
So you lose the differential ability and you lose
Racing vehicles usually use no differential anyway lol
could I be able to keep the reverse gear, or would it not fit
Is it possible to do this modification and keep the reverse option?
Nova Scotian here. Do you have any info on lowering the hydro static fear end in the newer ( 2001 ) craftsmen’s 19 hp ?
How.much for one of these
I am just amazed how much changes were made from the transaxles of old. The shaft size of 3/4 inch diameter is super lightweight. The old stuff was one inch or 1 1/8 inch diameter. Interesting video Sir.
i could imagine a race modded wheel horse 8 or 6 speed trans it would be heavy but bulletproof!
THAT IS A FACT FELLA !!!!@@111455
Do any of you know if the bolt holes on the transaxle would bolt on to a craftsman
What kind of speed are you seeing with these ratios? Also what tire size?
I'm just now getting into this kinda of powersports and that was a great video. Very well explained and easy to do. Thanks!
1 vid in 3 years. hahahhaha
Can you do this with a two speed??
I have this same trans. It's forward and reverse only
Way cool 👍
Does anyone know if this trans axle will fit on a John Deere L108
Good day from Ontario. Interesting video. So the way u r doing it u said 6.5 gar ratio. Do u know what the gear ratio would be on normal riding tractor ? U said parts from Princess auto, CDN Thanks .
Awesome modification! I'd like to make a quick correction on the bearings you've shown/listed, what you're actually after is a 6203-3/4-2RS. 40mm OD, 3/4" ID, 12mm wide are the specs and they're readily available.
That must be a very very old transaxle, not common. With 1 fwd , neutral and Reverse only ?
Is there a way to still keep n and reverse?
Do you know what the stock ratio is for these transaxles before this conversion?
Have you ever done a similar thing to a peerless 5 speed unit? It looks like you could completely remove the entire reduction gear assembly and run a keyed shaft in the rear and a sprocket and chain from the gearbox output to the rear axle. It’s something I want to try out, I don’t like overdriving the crap out of everything to go faster, it just ruins the transaxle
Mantap bang saya juga lagi bikin go kart 😁👍🙏
Is the level of complexity much different for a 5 speed (maybe its a 6 can't remember) craftsman transmission? My ideal scenario is to replace the transaxle with a longer one and then put it in a golf cart.
Great video! Couple questions. What do you use for wheel hubs? And do you change the input pulley size?
Have you ever done this to a mtd 2 speed ? It has high low and reverse wondering if it would be possible
Pulled one of these eith the 1 inch shafts for the same thing. Can't be much difference
What Diameter is the axle shafts?
Can I buy 1 from you
Why would you not want to seal the gear case and add some oil in the to keep everything lubricated???
Hey do you choose to change the gearing inside the transaxle as opposed at the input shaft? I am build a mild mower for one event am using a 719 axel
What do you do about brakes? Can the stock setup be utilized or will you need to install a rotor on the axle and mount a caliper? Any pics would a help as I'll be building one asap
ide definitely fill with oil....cool home design right on.
My mtd lawn tractor has the same gearbox. I took of the big rear pulley stuck to the gearbox and the pulley and shaft have a whole different pattern. It has 36 teeth with a converter with a six stat slot where the pulley goes. I cant find any other pulleys with the 6 star slot. I need a keyway shaft. Your shaft was as mine in the start of the video but in the end it was different. Can you tell me what you do with the shaft to make keyway pulleys fit
Sorry for the strange question, but... Is there a hydrostatic riding lawnmower transmission that is 13 inches long? Or wide? Or is there a transmission that I can cut down to 13 inches? What I am trying to do is build a galloping goose railcar. 5 inch scale 15 inch wide track. Im using a Briggs and stratton 17 hp motor and a riding lawnmower frame. I want to try to use the transmission to have forward and reverse.
that brass input gear is not going to be too happy without OIL IN IT... STP OIL TREATMENT up to the bottom of the axle shafts with some gear oil in it too. the gear oil will leak out of the axle shafts.... maybe not so much with the axle bearings that need to be regreased with REAL GREEEN/ RED GREASE so they last forever as the packing greease is the cheapest grease they can get away with putting in there to keep them from rusting on the boat from china. pry out the seals and pack in real US GREEN/RED grease and put seals back in. a good coating of green red grease on gears wud help too i suppose along with the STP oil treatment... liquid grease.
With this work for a Murray transaxle
How much would you charge for a kit and I would install it in the rear end?
buy the parts off of e bay and figure it out. worst thing is dragging all the nasty old grease out of it.... lots of rags and a cardboard box to throw the rags into. i wud put STP oil treatment in the gearbox before final sealing up. up to the bottom of the axle shafts so the oil doesnt leak out of the axle shafts.... STP OIL TREATMENT is generally tooooo thick to leak out of axle shaft. oil /grease the input needle bearings too on the input shaft tower as they need oil/grease. 2 of the 1/2" collars with allen head set screws blue thread lock on final assembly on those grub screws when u get it all together finally. the part # he gave for the bearings is ... are 12mm or 1/2"... axles are 3/4" or 1" on the HD models. so need 3/4" bearings for the axle if have 3/4" axle shafts... or 25mm/ 1" bearings for 1" axle shafts. they are made in the US so the axles should be US standards????
I have a 719 transaxle currently ordering my parts soon. I have a question, will I need to remove the input shaft from the case or get a new one? Also what are the size and length on your keyed shafts, viewing bmicarts they vary to 4.5 - 16) 3/4 with cut to length. Thanks for the video!
Input shafts and gears vary somewhat from model to model. Although all are 5/8 input shafts, some are machined down to 1/2" on each end. I prefer the full size shaft as the keyway in the 1/2" is very small and likely to fail with any amount of power. I use 3ft keyed axle shaft from Princess Auto. The 719 will not have provisions for ball bearings.
@@peilawntractorracingclubin7053 Alrighty thanks, I'll take this information and see what I can do with finding the proper length - size at princess auto, are you saying for the 719 model, they won't accept the ball bearings? Did all your keyed axle shafts come straight from princess auto;
@@jordon756 axles are available at Princess Auto. You'll see when you open up the case, the 719 model isn't machined to accept bearings like the 717.
