Product Details

Its neutral balance configuration, grey iron outer ring, and timing marks make it a practical choice for service work where the original balancer has deteriorated, separated, or lost accuracy. This part cross-references ATP 102011 and Dorman 594-080 for the same application.

Compatible With select Ford F-250 HD, Ford F-250, Ford F-350, Ford E-250 Econoline, Ford E-250 Econoline Club Wagon, Ford E-350 Econoline, Ford E-350 Econoline Club Wagon, Lincoln Continental, Mercury Colony Park, Mercury Cougar, Mercury Marquis, and Mercury Montego applications listed in the fitment data. The PB1210N part number is also a useful reference when sourcing a replacement harmonic balancer for these engine families.

Common Problems This Part Can Address

It also has no integrated pulleys, so confirm accessory drive configuration and pulley alignment during service. Use the vehicle’s service specifications for torque and installation procedure.
