m816 throttle arm hard to move

[m816Buch]

tried to move wrecker today but engine will not rev up..........throttle arm does not move, really hard to rotate manually and will not return without some force........

 

[timntrucks]

this may seam odd... but is the controls in the rear still on?? like engaged .. that makes the engine not rev up from the cab

I learned that the hard way on Tims 816

 

[m816Buch]

everything is disengaged in the rear, engaged then disengaged again.......still no throttle. i thought throttle arm should move fairly easy

Yes it should. If it doesn't move, time to pull the pump and have it gone through. Check your fuel for water.

THANKS i needed that!!!!!! Let truck set too long between usages i would assume. Checked manual, this pump seems like maybe not repairable by me for calibration purposes or can it be disassembled without having to do this
