Tri Pac apu belt

Yours doesn’t have a turnbuckle?

 

Try something like this.

With a good belt, it shouldn't take much tension(gates K060478 good replacement, can get at any auto parts store) just basically taking up the slack. I use a big flat box wrench between the alt and the engine casting(barely fits, so I don't have to move it far). Is your APU going to standby when you start the truck? My standby wire got pulled off the ignition switch accidentally and nothing lasts long while the APU is running with the truck going down the road.

Just some thoughts.

PS: thanks for the fuel filter video!

 

Go a few milimeters smaller on the belt size then. For example, K060475.

The tool wraps around and hooks into the alternator so you can apply pressure with a 1/2” drive ratchet.

 

I have a tripac on my truck and I had an issue with it and the mechanic replaced the belt by himself so it can be done.

 

You just have to remove the two bolts off the muffler bracket and let it hang. Then there are four bolts on the cover and possibly nuts on the inside, if the captive nuts have twisted off like mine have.
