Repair of the driving engine: what and how?

Due to the influx of a large number of driving engines of construction machinery other than excavators. I decided in a short article to describe their principle of operation and whether it can be properly regenerated. So to restore their efficiency at a much lower price than associated with the purchase of a new engine.

Principle of operation

The driving engine of the skid steer or forklift works on the same principle as those used in the excavator, but often there is no gear part in it. The drive from the hydraulic motor is transmitted directly to the driving system. The engine of the skid steer loader, the forklift’s construction resembles more the rotation engine in the excavator than the drive. The most common driving engines on our website are piston and rotary engines, the so-called rotators, which I described in another blog article.

Is it fixable?

The driving engine of a skid steer or forklift truck is normally “repairable” like any other part of it. The most common failures associated with the operation of driving engines have been described in an earlier blog article on repairing rotation engines for smaller excavators.

Is there any point in fixing it?

Driving engines, especially older type skid steers, are very hard to find on the aftermarket. And buying a new original is unprofitable. Because its price is well over 50% of the machine’s value. So the only reasonable option is repair.

Can failure be avoided?

Drive engine failure cannot be avoided. The elements used there usually do not spoil but simply wear out. They should be regenerated and enjoy the continued operation of our machine.
