Hey all,
I received my MK48 from the first set of J'ville units. It is in great shape with everything seeming to function correctly. There is one issue that I'm having that I would like to get inputs on from other MK owners.
When driving straight and around gradual corners there is no problem. However when I am driving very slowly and try to turn the wheels, the engine loads and dies as the articulation gets under load. You can hear the rpms start to drop as soon as the hydraulics start to activate.
I have the manuals and there is a vague reference to hi-idle although there is no switch, knob or pull. Does anyone know if the engine is supposed to compensate for the hydraulic pump load? Can some owners tell me what idle speed you are seeing at idle both in gear and out of gear and what happens to idle speed when you start to pull on the wheel when stopped or creeping? I am idling at 600 ( should be 690-700 so may be an issue) and it drops to 500 in gear stopped and with brakes on. When pulling on the wheel it comes down to 200-300 before giving up.
My air cleaner restriction gauge says it is ok. Bad fuel possibly?
Any thoughts are welcome.
Thanks
Jeff
