1994 mighty max grinds going into reverse

[Conra]

The synchronizing hub has nothing to do with reverse. Did you remove the shiftier yet?
I would adjust the clutch.
How far off the floor does it start to engage?
It should start to grab about 1.5 to 2 inch off the floor. If it's more then that adjust it. Adjusting is easy on the cable. Just pop open the hood. Grab the cable with your left hand pull it away from the firewall and turn the adjuster tell it touches the wall. Then turn it back 1/2 turn.

One common problem is the pilot bearing or bushing being warn. That will keep the clutch turning when you push in the pedal.
The reverse will grind if the clutch disc is spinning. Froward gears have the syncro or blocking rings that will add friction to the next gear you are moving into. This slows down the gears enough to make a smooth transition.
I would drop in a anew clutch, pilot bearing and pressure plate if you keep having the problem and everything else is OK. But the syncro is a full rebuild and taking apart the trans and gears.

i haven't removed the shifter or adjust the clutch yet. I'm planning on doing it on Monday. The clutch seems to be fine. I mean sometimes I have the press it all the way down before I have no resistance going into 1st gear. Even with some resistance going into 1st gear, it doesn't grind at all. I have also noticed that when I start the truck in first gear I can shift to reverse without a problem, it will only grind if I had drove it for a while.

With this info it tells me the cable needs to be adjusted.
The reason it doesn't grind when starting in gear and holding the clutch is because the disc is held in place by the rear end through the transmission gear set. So when you go from the gear it's in to reverse doesn't give the disc enough time to build up inertia.
Now when you try to go into reverse after driving or starting the truck with the clutch engaged. The slight amount of friction between the pressure plate and flywheel is enough to make the disc start to rotate.

Sweet, I thought it was going to be something major that I had to fix. So far I'm loving the truck. Cheap on gas, and it's very reliable for a 22 year old truck.
