Clutch with torque amplifier on 460

lanopie · Jan 27, 2014

I've replaced the clutch a few years back on an International 460, excessive work, and now when I put the lever in High, it runs as it does on Low.

Is there an adjustment that can be done or does the clutch have to be replaced again?

Thanks for any help or suggestions.

The TA clutch is either worn so as to not provide any lockup, or the disk is disintegrated. The TA clutch is in the front of the TA, and behind the master clutch. If the tractor pulls well, (though in TA reduction, the master clutch is OK) You can see into the housing from the access cover to get a look at it (IIRC) shreaded lining material is going to be clearly visible, as would a thin and worn TA disk. Using it (If it never kind of shifts into direct when not ubder load) probably won't dammage it more. If it does try to use direct, it might be best to fix it before needing more expensive parts.
The only adjustment issue is to make sure the TA clutch is not being held in the reduction position from frozen release shafts or bearings. If the TA release bearing cross shaft is not turning when the lever is put forward, (and it stuck) that might be it. Jim

Which clutch did you replace?

There is the main clutch on the flywheel.
There is the TA clutch as Janicholson describes.

Your problem sounds like the TA clutch has failed, as Janicholson descirbes. Either that, or your TA adjustment is WAY out of whack.

The TA clutch usually goes because the adjustment was wrong. If you set the short linkage between the main clutch arm and the TA arm too tight, the TA clutch slips and burns up. Same thing happens if you adjust the TA lever linkage too tight.

There is an inspection cover on top of the torque tube (under the gas tank) that you can remove to look at the TA clutch.
