SPM-HEP-4141 is the complete TD04L4 turbocharger with wastegate actuator and oil line, ready to fit. It is used on Caterpillar D series skid steer and compact track loaders. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
It replaces Mitsubishi 49177-03242 and Kubota 1J773-17013.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Loss of power and black smoke
A worn turbo stops building boost: the machine feels flat under load and smokes. Check the air filter and intake hoses first, then the turbo.
Oil leaks and blue smoke
Worn shaft seals let oil into the intake or exhaust. Replace the turbo before oil starvation damages the engine.
Noise and shaft play
A whistle or grinding from the turbo, or play in the shaft, means the bearings are going. Change the turbo before the wheels touch the housing.
Fitting tips
Fit new gaskets, prime the turbo with clean oil, change the oil and filter, and check the oil feed and drain lines before starting.
