The defect
ON CERTAIN MOTORHOMES EQUIPPED WITH CATERPILLAR ENGINES, THE ADJUSTABLE PEDAL RETURN SPRINGS MAY RETURN THE PEDAL SHAFT TO THE HOME POSITION WHILE NOT FULLY RETURNING THE POTENTIOMETER KEY TO ITS HOME POSITION.
The risk
IN A NEUTRAL OR NO LOAD SITUATION: THE ENGINE WILL CONTINUE TO INCREASE IDLE SPEED UNTIL IT REACES FULL GOVERNED RPM. THE TRANSMISSION WILL NOT ALLOW SHIFT FROM NEUTRAL TO ANY GEAR OVER 900 ENGINE RPM. IN GEAR OR UNDER LOAD: THE ENGINE MAY NOT RETURN TO 725 RPM (NORMAL IDLE) WHICH WILL REQUIRE ADDITIONAL EFFORT BY THE SERVICE BRAKES TO OVERCOME THE ADDITIONAL ENGINE RPM DURING BRAKING, INCREASING THE RISK OF A CRASH.
