A crankshaft is replaced when grinding is no longer possible, when it has cracked, or when the journals are worn beyond size. Main bearings in the matching size go with it.
We stock crankshafts from the BP and Arrow ranges, for tractor and truck engines. Connecting rods and bearings go with the crankshaft, so the whole assembly comes from one source.

KHD Deutz and other engines from the truck range.
Send the engine type and the size the crankshaft was ground to and we check what we have.

After the crankshaft has been ground, the bearings have to follow the new size. We keep main bearings and small end bushings in standard and repair sizes, so the assembly goes together without waiting.
The engine type and whether the crankshaft has already been ground, and to what size, are enough for us to check. That also decides which bearings go with it.
If the size is not known, send the make and model of the machine and the number of cylinders, and we check the catalogue and tell you what we have in stock.
Anything not in stock we obtain, with a lead time we confirm in advance. We deliver across Serbia.
