Anyone had a problem with low RPMS. I have an f5. I ran it a week ago and the thing was a rocket. RPM s were at 8400. Today I got it out and the thing would only hit 7800-7900 RPMs. inspecting it closer I discovered that the wires by the plug to the servomotor had gotten into the clutch and rubbed some of them in two, and had bared the others. I tried another servomotor out of another f5 we had sitting around the shop. The servomotor wont take up the slack in the cables, so they droop and just about fall out of the motor, and most of the time the servomotor wont open up except clean-up on the start. According to the 2002 service manual this is normal if the voltage is incorrect. Also, my f-5 is different as far as wiring to the other two f5's that we have in stock. Mine has a oil sender adapter with pn 686-101 stamped on it. The other two dont have this on them. Anyone else had this happen to them? Any solutions that anyone knows of? This is terrible when cat hasnt even gotten out the new service manuals for these sleds yet. It kind of makes troubleshooting hard.
