Combines torque sensing spring

If the rotor belt starts slipping on our 2388's we grease the torque senser when the rotor is set at full fast speed, then we start the machine and slow the rotor to as slow as it will go and we grease it again. This gets the grease worked in completely. It sounds like this is not going to solve your problem but it is a good general rule to follow for anyone.

a lot of rotor belts heat up and fly apart because of heat of slippage. three speed gearbox helps. always keep rpm in the top half of gear range. not using lithiun grease will make belts slip nore because it will make teflon bearings sticky on shaft. the new combines 03 2388 run a heavier spring than that. 900 lbs. i think with the afx. rotor. the heavier spring the harder it is for the elec. motor to get max rpm. there is a kit to keep belt cleaner and cooler ask your partsman.

We have updated our 1680 to the current specs. I think it was a 900lb spring and there is a thrust bearing behind the spring now. We haven't had any problems since, and the wheat straw was really tough and green this year. If you take the torque limiter apart you can see how freely the hub slides on the chromed shaft. If it is hanging up a little bit, use some light sandpaper on your finger to remove a little of the TFE bearing. It won't take much at all to make it move freely, which will really help the way it works.

I've had the same problem it's not 900 lbs. its 600 it's for a rice combine be sure your torgue sensing unit is clean!!! and your rollers are not worn take it off and tear it apart the 600 lb spring works great and the air deflector for the fan is a must it keeps the rotor area clean. and the belt cooler. also new combines than 98 have groved pullies so they clean the belt.
