MTD transmission transaxle skipping, noisy, or no forward motion
HTML-код
- Опубликовано: 12 сен 2024
- This transaxle is a standard single speed unit from the rider mowers that have an F-N-R selector lever and another lever on the dash panel for speed control. These gears inside are sensitive to the linkage adjustment, and they tend to wear out. Most tractors that have this problem have either skipping, noisy or no forward gears, however, it can also occur in reverse.
What I've found is while the gear selector cog does wear on the edge, the gear selector drive shaft bushes also wear causing the pinion to be out of alignment. By putting a washer behind the forward drive ring around 1mm thick I've noticed that the gear engages better and doesn't skip anymore.
Excellent info!
Just wanted to take a second to say thanks. I just used your wisdom on a 2004 Huskee 23HP that was doing the same thing. Reversed the gears and the coupler, and it runs like a new one again. Saved a bunch of cash, and maybe get another bunch of years out of it. Many thanks again !!
That's great! Thanks for the awesome comment! 😎👍
Good Morning. I would say have a Happy 4th however being in Canada . I hope you have a Happy weekend.
Thanks Bill!
I'll give this fix a whirl....there are two variants of this type of trans F/R assemblies...I wont order one because I cant pin down which one I have....so I'll just flip the innards and be done with it! Thanks for verifying my hunch that this is a sound fix.
I hope it goes well for you Paul. 👍
So you basically used the good unused sides of each gear? Genius!
That's exactly what I did. Brand new gears aren't super expensive, but this repair was as good as new. And no cost in parts.
@@randomwrenching I’m having the exact same symptoms as that tractor, because of your video I’m gonna crack that sucker open and try it! Thanks buddy
No worries, let me know how it goes for ya. Be aware of the shim positions on each side of each gear and get them into the right spots. It's important. 😎👍
@@randomwrenching thanks bro…I’ll send you the video and shout you out!
My MTD 92 T also skips while driving. I just don't know how to adjust the shift lever so that the transmission does not wear out after the repair
You’re lucky to have AC in the shop.
And a big furnace in the winter!
I mustve put something back together wrong. Flipped all 3 around and I lost forward completely but wow will it back up like a racecar
I have a similar problem when the front drive belt broke a weird C clip was on the deck and since that my mower doesn't drive forward very fast.
Watching this because my mower makes a big ass clank sound then moves forward for 3 seconds then just goes right out of gear and repeats. My mower is old though so it's hard to tell if I'll be able to find whatever it needs
Sounds like it might be a similar problem. Let us know what you find...
Do you know the ratio of these transaxles? That is, how many turns of the input/pulley shaft for one full rotation of the axle shaft? I'm thinking of playing around with the pulley sizes to give me more torque up hills and I want to get my calculations right before investing in any new parts.
Sorry, I don't have that information.
What would cause this trans axle to keep popping the drive belt off when switching forward to reverse and reverse to forward? The transaxle also makes a howling sound now and won't go faster than speed 5 and then I can hear rattling after that
The sliding sheave pulley that changes speeds can get seized and stop proper speed adjustment. It can also wear the bushing out and rattle quite loudly.
impressive. so it takes grease and not oil?
This is a weird grease in this trans. And the rider in the video is still running and driving just fine to this day
I tried same thing just turn around. But I only turned that middle gear, forgot completely those big ones.
The bigger ones are the problem.
Did you flip the slip collar as well?
I believe I left the collar as it was, just swapped gears side to side.
Thank you
But it will drive just fine on flat land and also going back up the little hill
I have the same tractor but when I just start going down a little hill it starts jumping. Could this possibly be my culprit to? Great video
I imagine it's possible that yours has a similar problem.
Hello.
Is the housing steel? I was going to attempt to weld mine but don't want to go through the hassle of all the setup to find out it's aluminum.
The axle housing is aluminum
@@randomwrenching Fml. Well, saves me a lot of energy, thank you.
Hi!Did you swap forward gear with reverse gear? The inner diameter of these gears seems to be different.
I did swap the forward and reverse gears. Inner diameters were the same on the unit I worked on.
Thank you :)
I've got a 99 16hp MTD 13cd768n678, and the diameter of my forward gear is slightly smaller than the diameter of the reverse gear. So swapping them is unfortunately not possible.
Interesting. I haven't seen that
I ordered a new gear today using the original part-numbers and this is what the list said:
Fwd gear: PINION 42 T., SM. BORE HOLE
Reverse gear: PINION 42 T., BIG BORE HOLE
Which means I wasn't mistaken (unfortunately xD)
Don’t be so miserable
