i have a question. i have a np 435 that grinds going into 1st. and has issures going into reverse. Is this a low fluid issue or is it because i dont know how to shift with out syncros??
2nd thru 4rh shift just fine and clutch is rock solid

 

You need to be completely stopped before shifting into 1st and reverse. It sometimes helps to hit 2nd while the clutch is depressed and then drop it in 1st. Could be a clutch adjustment or something internal with the transmission too.
I'm sure someone with experience will chime in soon.

 

for 1st i am dead stopped same with reverse

 

Sounds like the clutch is not properly adjusted. First and reverse run off of the same gear, which is not synchronized. If the clutch is not releasing fully there will be no input shaft braking action in those two gears like there would be if you were to try to put it in second, third, or fourth. Run on sentence of the week, I know.

how do i adjust the clutch on this truck?? linkage tranny

 

Say you push the clutch all the way to the floor and put it in any gear. how much do you have to release the pedal before the motor starts to dog or the truck starts to move?

To adjust the clutch you need two 3/4 inch wrenches, or a couple crescent wrenches. There is a rod on the driver side of the truck slightly below the frame, between the frame and the engine/tranny. It has two 3/4 inch nuts on it, and it actuates the clutch release fork. It sounds like you need to make the distance from the clutch fork(goes into bellhousing) and the nuts longer. The nut towards the front of the truck would need to be turned counter clockwise a few turns and then the nut on the other side of that link would need to be turned counter clockwise a corresponding amount in order to snug it up like it was before you loosened the first nut. It's very simple, just hard to explain in words.

You adjust the freeplay based on measuring from either the floor or the steering wheel.

You want around 1.5" freeplay from fully out until pushing in the clutch pedal you start to feel resistance.

If at a dead stop and the gears grind the transmission internals are still spinning which means the flywheel and clutch plate are still in contact.
