Frequently Asked Questions
What is the difference between 1104C-44 and C4.4?
They are the same engine: the Perkins 1104C-44 is the base unit, and C4.4 is the Cat part number badge used in Caterpillar machines. The 3054C shares the same architecture. Verify the build level by engine serial number.
What is included in the kit?
You can order the upper (top) gasket set, the lower set, or the full set which includes the head gasket and oil seals. Exact contents are confirmed against your engine serial number before order.
Which part numbers should I reference?
On the Perkins side the reference families are U5LT0354, U5LT0357 and U5LT0350. On the Cat side T402946 (upper), 3681E051, 297-1546 and 277-5156 are common references. Send your engine serial number and we will confirm the right set.
Which machines use this engine?
Cat 312 class excavators and Cat 420D/420F/430D/430F backhoe loaders, plus Perkins-powered tractors, forklifts and industrial equipment. The engine model and serial number must be verified for the target machine.
Is there a difference for turbo engines?
Yes - the 1104C-44T and 1104C-44TA turbo builds use different gasket pieces. Tell us the exact build code when ordering.
Are the parts inspected before shipment?
Each kit is checked for completeness and component quality before packing, and export-standard packaging is used to prevent damage in transit.
