NV4500 Tranny Trouble

[6.5 Detroit Diesel]

I will be checking it out. Thanks! Any other suggestions.

Okay, so I disconnected the hose that runs up to the reservoir and plugged the bottom of the reservoir. I then filled up the reservoir with new fluid and tried the clutch. Basically no resistance, the clutch goes straight to the floor. So I am figuring that that is the problem, the master clutch cylinder. New one here and ready to go in! Also got a new slave cylinder as well as I am sure the old one needs to be replaced anyways. Hope that is the problem, though I can't see what else it could be!

dood, you shoulda called me up--I've got a brand spanking GM master cylinder in the box that I found in the back of that red and black truck I parted out . . . oh well.

Don't wreck your tranny :-)

Nice dood. I had known back when I was out there that this was going to happen, we could have avoided it, eh? Oh well, sure you will find use in your tranny swaps. I gotta get the truck back together tomorrow though.

New master clutch in. Put half a liter of fluid through trying to bleed out the stupid line. Still won't go in when running. If you jam it in, sounds like it is making light contact with the plates. Clutch won't stiffen up. Removed the inspection bolt and found that the fork moves around half an inch with pedal fully engaged. ?????????

Could be the pivot ball has gone away at the clutch fork. I've seen them wear clear through the fork. Sounds like time to pull the trans and check deeper. When moving the clutch line don't put any stress on it. DISCONECT AT BOTH ENDS before moving things around.

Yea, sounds like it is time to move in. Did some research and found some people have had the fork actually bend after a while. Not sure how much of a possibility this could be though.
