I have an older model 1816B that the warmer (operating temperature) it gets, the less agressive the left side drive becomes.
The right side works normal, left side needs some attention.
Is there anybody out there that knows how the system functions, it also has a noise in the system, like oil going over a relief. I have not installed any pressure gauges on it. There does not appear to be any test ports installed for such a purpose.
There are two pumps and two drive motors, I am assuming two individual relief valve assemblys also. When they built it, they compacted it into a small package, so major surgery is necessary to even look at the motors, let alone work on them.
