I have a Farmall 300 with a bad torque amplifier. I have the Farmall TA rebuild video. According to it all that is needed to rebuild a TA is to replace the eight rollers that get flat spots on them. If that is the case then why do rebuilt TA's cost $600.00? I would imagine there is more to it than that. I dont mind paying a skilled mechanic for a good part but I refuse to buy no name parts that come from china. My question is can I rebuild a TA myself? (I have a complete machine shop.) Or who rebuilds TA's that I can send mine to? I know there are lots of places I can send in for an exchange but I want to talk to the guy that is going to do the rebuild. Thanks, Danny

There's a clutch and some adjustment stuff to but I would say you could do it if you have a rebuild video to walk you through it. A good manual would be handy to

I have done a few in the past. There is more than just the rollers that need to be replaced. The ramps get grooves too. Dry clutch is worn etc. Seals & bearings. You will know once you get it apart.

There are four considerations for your answer.
The rear of the TA has a sprague clutch (ramp rollers) easy to replace with the tools you indicate.
The clutch on the front is a standard friction disk and pressure plate with a throwout bearing. No issue, easy.
The internal parts should be checked for gear tooth wear and bearing support wear. If you know what tooth and bearing wear looks like no issue.
The last is adjustment and re-manufacturing of pins and clevises in the linkage.
The tractor must be split in two places to get it out. it is heavy and safety is important.

If you can run a machine shop you can rebuild it yourself. If you don't trust yourself, you could always take it to the dealer/a local tractor mechanic for rebuild. The double split is usually the expensive part of the job.
I'm guessing as a machinist you could repair the worn parts better than most people doing the rebuild. Want to do my MD throttle??? :lol:

If selling a t/a unit as rebuilt and standing behind the work, short cutting by just fixing the ramp, rollers and carrier roller contact surface won't get it. Common for shaft splines to be worn, sometimes bearings that can't be inspected unless unit is disassembled are bad. If the pilot needle bearing on the transmission input shaft part goes bad and ruins the shaft thats a big cost. Planet gears and shafts needle bearings sometimes have inbedded places in the shafts or gears or worse. Ends of planet gears and thrust plates sometimes gall.
Don't know about others, but I can't compete with rebuilt unit prices on the repair of one if labor cost is included unless most parts of the unit are good for reuse. Wouldn't go through the work of removing and installing a T/A unit without a complete check and clean up. Doing your own without a guarantee or labor costs may be different.
Probably you can rebuild the unit.

I don"t know your abilities so I can"t say one way or another if you can do it yourself. To rebuild a ta and make everything right all bearings should be replaced, carrier needs to be machined for the oil seal and ramp areas. Gears need to be timed. By the time you buy the parts it"s going to cost you more but at least you know what you"ve got. I tried to email you back but it says your address is invalid. I will call you later today.
You can save a lot of money by just replacing the ramp and rollers, and anything else that's obviously shot. Only fix what absolutely needs fixing.
The way most of these tractors are used nowadays, it'll probably work fine and probably last you the rest of your life, even well into the next life.
Note the use of the word PROBABLY. You're betting on odds here that something else isn't almost ready to break, forcing you to tear into the tractor again.
The $600 unit is completely rebuilt. All new wear parts. If you put it in there is little chance that you'll have to tear the tractor down for TA problems again, ever.

I have "reworked" a TA by just ramps, rollers, pins, and springs. It works fine. All bearings seemed to be ok, the above parts had just worn and flat spotted.

Is it worth buying the heavier sprague clutch instead of replacing the ramps and rollers? The ads sound good but is it worth the money, or is there possibly a drawback to this upgrade?

I have seen rebuilt units sold as HD with that sprague clutch. I have not personally had dealings with it.
I have a mechanical TA in my shop that probably just needs ramps, rollers, pins and springs. One day I may OH it and may look into the HD clutch instead.
I'd be interested in information on the HD parts.
