I have a 2014 Retired Prime truck . Question about Idle on trucks

Idling will kill the engine faster than anything. Actually it kills the DPF and EGR. Your gonna need the " One Box " replaced at around 600K, 800K is the record for our little fleet. It's $8K. Save some money.

You should be able to turn the cruise on at idle, and bump it up to about 800 RPM. This is better for everything.
Good luck.

 

What do you mean by low hours on it? If it's a used apu that was on the truck since new it should be around 5k hours. Best thing to keep your apu functioning is to do a pm about every 400-500 hours. Not the 1000 hours that they might have told you if it's a rigmaster apu.

 

That is low if it's original. Good luck with your truck. Prime does a pretty good job at maintaining there equipment.

If the belt starts to squeal on the apu, don't just assume it needs to be replaced. The one thing the rigmaster failed at was not putting a belt tensioner on the apu. If it starts to squeal, it most likely just needs to be tightened up. You loosen the lower bolt on the alternator and then push the alternator as hard as possible and retighten the bolt. That usually solves the squeal and saves you $60 for a shop to just replace the belt.

 

We would get the APU fixed ASAP in the summer. Stay in a motel room if it was too hot in the truck.

Some trucks will idle and some wont, depends how deep the shop guys dig around looking for stuff to "fix". Although they should undo any of that before they sell the truck.

 

You would be surprised how much you could fix yourself on the rigmaster. The only big issue I have had with mine was the water pump leaking and after watching the shop replace it, I could it myself next time no problem.

Also, wash the engine of the apu every couple months. That keeps the parts from wearing out to soon. All road grime gets in there and starts messing things up.
