SPM-HEP-4772 is the BorgWarner S200 type turbocharger without wastegate, with a twin entry (divided) four bolt exhaust inlet flange, an aluminium compressor housing and a cast iron turbine housing. It is used on John Deere 6068T 6.8L engines. 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 John Deere RE508657 and BorgWarner 177261.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

What it does
Exhaust gas spins the turbine, which drives the compressor wheel on the same shaft and pushes more air into the engine. More air lets the engine burn more fuel cleanly, giving the rated power.
Where it is used
Made for the John Deere 6068T 6.8L diesel engine.

Yes, it is a direct replacement for the John Deere RE508657 with the same fitting.
Often as long as the engine, 8,000 hours or more, when the oil and air filters are kept on schedule. Most turbos fail early from oil or dirt problems, not age.
Blue or black smoke, a whistle or siren noise, loss of power, oil in the intake or exhaust, or the shaft rubbing the housing.
Most failures come from oil starvation, dirty oil, or something passing through the wheels. Find the cause first: a blocked oil feed or dirty air path will kill the new turbocharger too.
A little radial play is normal on journal bearing turbos. Wheels touching the housing, or any noticeable end float, are not.
No. It is an aftermarket turbocharger made to replace the John Deere RE508657. It is not made by the original manufacturer; the number only shows what it replaces.
