Frequently Asked Questions
What fan belt fits a Case 9020 excavator?
Broken Tractor offers engine fan belt J911557 for Case excavators with Cummins engines, and it is listed to fit the 9020 and 9020B. The same belt is listed for the 688, 760, 860, 888, 1085C, 1088, 9010, 9010B, 9030 and 9030B. Because engine options can vary by machine, match your old belt's part number before ordering.
What belt tensioner fits a Case CX130 excavator?
Engine belt tensioner J936203 is listed to fit the Case CX130 and CX160 excavators. It is also listed for the Case 688, 880D and 9010 excavators. Fitment can depend on serial number and engine, so compare the part number on your current tensioner or confirm with our parts team.
What fan belt fits a Case CX50 or CX55B mini excavator?
We carry fan belt VV12961242380, which is made for the Case CX50 and CX55B mini excavators. It is a different belt from the J911557 fan belt used on the larger Case excavators with Cummins engines, so check your model before you order.
What are the signs of a worn fan belt or bad belt tensioner on a Case excavator?
The most common signs are belt slippage and engine overheating, because the fan and accessory drive are no longer turning properly. A worn belt or failed tensioner can lead to engine damage if the machine keeps running hot. Replacing the belt and tensioner together helps restore proper belt tension and fan operation.
Which engine fan support fits Case CX210, CX240 and CX290 excavators?
Fan support bracket J913433 is made for Case Cummins 4B and 6B diesel engines and is listed to fit the CX130, CX160, CX210, CX240 and CX290, along with classic models like the 660, 860, 960, 688, 880D, 888, 1088 and the 9010 through 9030B. Case 9040 and 9040B excavators with the Cummins 6T-830 or 8.3 diesel use fan support J942896 instead. If you are unsure which engine your excavator has, call (800) 909-7060 with your model and serial number.
