D7R II CAT Tractor . . .Hands Off After Fuel Injector Misfire

Fuel injectors on the new D7R dozer have been known to misfire. That causes the vehicle’s engine to run rough and, in some cases, stall out.

A misfire can also make the fuel injectors seize. That brings your construction operations to a screeching halt!

Operators, if that happens to you, don’t touch or try to repair the fuel injectors yourself. That goes for you, too, mechanics!

Instead, eyeball the serial number on the dozer’s data plate. If it falls between KNA00214-00217 and KNA00219-781, you’ll need to contact your local Caterpillar dealer to schedule a repair. Tell them it’s regarding CAT Service Letter #PS44681.

Travel and mileage for the repair are included, so there’s no cost for the visit.
