Hi i have a cat 287b tracked skid steer loader we have just fitted 2 new hoses to left drive motor and now the machine turns no problem but to travel backwards only the left track moves and right track loads hose pressure but no movement forward it just does not move any suggestions its like the brake is not deactivating
Your post isn’t very clear. Are you saying that the machine moves forward fine and steers ok going forward but only the motor with the recently replaced hoses wants to rotate going in reverse.?
The motor that had new hoses fitted operates correctly turning left or right But it will not go straight back wards or forwards It loads the bottom large hose up but does not travel
Was the motor working OK before the hose change.? It might be a silly question but are the hoses connected correctly.?
Yes motor was fine The hoses were fitted back on wrong way but are now correct
The incorrect initial installation may have buggered something up in the motor. Either that or you have an electronic fault. Do you have Cat ET or at least some type of scanner.?
No don't have a scan tool
In that case you’re going to have to get hold of one to at least rule out an electronic fault in the drive system. Unfortunately the B Series machines don’t have on-board diagnostics.
Here’s a suggestion. Maybe with hooking the hoses up wrong the travel motor speed/direction sensors have got discombobulated. Get the machine up on blocks or stands and run each motor separately in the same direction, then try to run them both together in the same direction.
Also a question. When everything in the drive system locks up does the master fault light (exclamation point) on the monitor panel light up.?
