~ Is there a way to bleed the injectors? Is there any other tool you could use to change the air compressor belt. ~
First you get it running, It should make a heck of a mess with just the lift pump ON with the little bleeder valve open between the secondary filters.
Second, one does not need any special tools to tighten up the compressor belt, see photos. The fine screw mount that the thing adjusts with must be kept lubed up. If that is so then loosen the two and 9/16" bolts and crank the engine without starting it once. That puppy will tighten right up then retighten the bolts. If is all corroded then lube it up and use some tools as in the photos. One has to hold the rusty hex in the center of the photos and pipe wrenches are crude. Pipe wrenches are too wide, use a 1-13/16" flat wrench.
Turns out, just keep the fine threads lubed up. The design is rotation of component disallows loosening.
Just bump the engine to position so that one can loosen up good both front clamping bolts with a 9/16” six point socket. One on top one on bottom works good. That is why it is built that way. Disable engine starting by keeping the engine fuel cutoff OUT. Just bump it.
Otherwise, Just stand next to truck and turn the back of the pulley CCW wise and the pulley screw will walk right thru the clamping device. Do not tighten belt too much, just so the belt don’t slip.
So just use the 1-13/16” slim wrench.
Then go retighten evenly both 9/16” head bolts. Done. When adjusting by hand just hold the back of the pulley casting with a 1 -13/16” slim wrench.
