GEORGE C. - Sounds like your talking about the engine clutch, not the PTO clutch. Charlie's correct, use an anti-rattle spring on each pin. But my manuals doesn't show the right way to install them.

You have to unbolt your engine and slide it forward so the three driver pins disengage the friction disc. Then slide the springs on with the bent spring ends towards the back and slide the engine back and bolt it down. Then pull the hooked ends of the anti-rattle springs up over the edge of the friction disc. The centrifugal force of the running engine bends the ends off of the friction disc if the springs are outside of the friction disc and they will be "MIA" in about a minute of running.

RICK B. - I'm curious what weak spots you're talking about in GD CC rearends. I know about the diff bearing retaining caps, and the top sliding gear transmission shaft. Anything else? Granted I haven't been to a plow day with my 72 since the K321 replaced the K241, but I've never had ANY rearend problems with that tractor and it's pulled a LOT of stuff it shouldn't have in the 30 yrs I've had it. Now roll pins & drive shafts, YES, been thru several of each once I got rid of the K181 engine that was in it when I bought it.

I bought my Firestone 23-8.50 lug tires a month before PD #1 and have always run 2-3 sets of weights on that tractor, 70-80 pounds per tire. You'll run out of traction long before you break anything in the rearend unless you really abuse it. While breaking in my K321 I made two black marks 100 feet long 8-1/2 inches wide across my concrete driveway in 2nd gear with that 72. I almost had the F'stones Smoking! I was "pulling" a 7000# Farmall M.

When I say over centre. The red arrow, that arm will rotate back towards the tractor and when you try to lift the blower you will bend or break the rock shaft or bend the lift arm.If all the slack from the lift system is removed like you have done,you won`t have that problem. because the lift arm supports the weight of the blower and it can`t fall and go over centre on the lift arm now . have a great time using that blower, they will move tons of snow.Now you will be able to fill in your neighbours drive from your drive with your snow. lol

Dennis,
A the top shaft is a bit weak, yes. The bearing caps (stamped steel) are weak. The "detent" for staying gear under load is weak. The shift forks are prone to cracking and breaking.
The ammount of available "mesh" between the gears is pretty minimal also.
Yes, I'm picking apart the best garden tractor transmission out there, but there are weak areas when you are pushing it past its design limits. (14 hp+) Time and use WILL find these areas.
Everybody has had a gear drive pop out of gear plowing right? Usually when pushing a little hard in 2nd gear in tough ground.
I've built lots of puller transmissions and clutch set-ups, so I am really aiming at SEVERE use. I only like to build things once.

RICK - When I destroyed the T/O bearing in the 72 this summer the clutch wouldn't release completely, and the transmission wouldn't fully engage reverse or first gear, 2nd, & 3rd were O-K. I pulled the shifter off the top of the tranny for the First time EVER and the capscrew holding the 1&R shift fork to the shift rail was loose. I tightened both forks up. When I was breaking the K321 in I had the tranny pop out of 2nd several times, but never had a problem when plowing when the tired old K241 was installed. I'd like to think the popping out of gear problem was caused by the loose shift fork, but I haven't tied onto any large immovable objects yet to check.

Yes, pulling puts ALL kinds of added stress on those rearends. But they were designed to handle a NINE horsepower smooth running 4-cylinder engine running 1400 RPM. And to make them work behind a single cylinder 3600 RPM engine the 7:1 reduction housing really adds stress to an otherwise bullet-proof design. That top shaft only turns 515 RPM so with anything over 10 HP it's seeing about three times the torque it was designed for.

The old 70 I have Dad bought new in '65, it mowed two rather large farm yards every week for seven years then mowed only one for the next 25+ yrs. Under a hard pull it would pop out of 2nd 30 yrs ago! But it's been shifted into & out of 2nd a million times. What amazes me is the rearend does not leak..... anywhere. And it has oil in it!

And I agree 100% with you about only building something once. Thanks for the reply.

I'd still like to make a real "Super Garden tractor" out of a Farmall A or B rearend. Heavier everywhere, four forward speeds, could use taller tires, 15 or 16 inch.

I wondered why the heater in the newly insulated Cub shop was running a little more than usual. LOL
I guess it was a little chilly outside.

Charlie, it could be worse. If you used Don Ts' thermometer it would be reading 20* inside and -8* out.

well I have good news! my loader is almost completed. They just have to install a few jumper lines and its finished. I did not have my Camera with me so no pictures. I was impressed as to how it will look when finished. I will have to install all the decals that I have and call it completed. I will post some pictures when I get the loader home and have touched up the paint.The guy at the shop has got IH tractor fever and bought a 782 and a 682 last weekend with decks and a snow blower. He now wants an Original . He is planning to build a loader and back hoe on the 782 . He ask if I wanted a back hoe also for my 129. decisions decisions lol.I do think a back hoe on the 129 would be COOL . later Don T

Maybe I should scale down a few cubs and add that back hoe to my 129 loader .

Look what got saved from the trash! A gentleman found this while cleaning out an old IH dealership building and saved it from the trash several times. He said they REALLY wanted to throw it away. He thought somebody would think it was cool. I think he was right!
It's a bit rougher than the one Art has, but who's complaining.

This came home with me, by the way.
