1600 Backhoe Loader Reverse-o-torque

What'cha think?

You operate it by stepping on the appropriate direction pedal. Depressing a pedal part way engages the reverser in the direction you want to go - depressing the pedal farther advances the throttle. The small pedal to the right of the FWD pedal advances the throttle while leaving the reverser in neutral - for quick picking/dumping the loader, etc. The reverser pedal linkage is complex and requires proper (and frequent) adjustments in order to work correctly. It's also sensitive to worn shafts and loose bushings - as the parts wear the governor will not bring the motor up to full RPM with a direction pedal all the way down.

Stuff to look for:

1 - Obvious leaks from the reverser and it's cooling lines.

2 - "Burping" of tranny fluid out of the vent can on top of the reverser. Apparently it's normal for a bit of fluid to spit from the can now and then. A lot of fluid venting however means troubles.

3 - Quick pickup of forward and reverse. As the reverser gets worn it seems to require longer to engage after stepping on the pedal.

4 - Worn linkage. Put the main transmission in neutral then step all the way on one of the direction pedals. The tach should indicate at least 1,700 RPM or so. If slower, it means the linkage is worn or needs adjustment.

5 - Slipping. If possible, run the tractor on the road in 6th gear for a few minutes. Make sure the reverser doesn't begin to slip as it heats up.

6 - Shuttle the tractor back and forth a few times in several different gears to check for proper shifting, overheating, etc. Also check that the reverser temp gage works, and that it stays below the "SHIFT" mark on the scale after shuttling a while. DON'T use the reverser to quick change travel direction. Instead let off the pedal, use the brakes to come to a complete stop, THEN step on the pedal for the opposite direction. Note the reverser has a characteristic gear whine or whistle when moving in reverse - this is normal.

Hope some of this helps...
