The "weakest point" of the LS3907

The "weakest point" of the LS3907

Our many years of experience in refurbishing the K118690N00 - LS3907 compressor from Knorr-Bremse says yes, it is clear that the weakest point of the unit is the clutch.

While the crankcase, cylinder head, crankshaft "can withstand" the damage it takes, the clutch failed in 95% of the cases turned over by us.

As a result, it is not enough to perform the usual processes such as surface treatment, boring, honing, seals, valves and pistons replacement.

Fortunately, Knorr-Bremse also recognized this, making the factory part available to the market under the following part number K097453K50.

Although the price of the part is a bit harsh as responsible part refurbishers, we will always replace this unit as well, whether the customer says the old one “still goes a few kilometers” or not.

This way we can always offer 12-months warranty and guarantee the renovation we carry out and validate the processes required by ISO 9001: 2015
