Hello -
Got some clutch issues on my - 1990, F350, 7.3, zf5, Banks Turbo, Crew Cab.
It was a stiff clutch - now it's like there is no clutch?
Background:
My clutch had been stiff for a few years. I hypothesized about the firewall/linkage being an issue, but never found any significant movement; thought that maybe there was an issue with failure of the slave/master or air in the line, which I replaced say 10 years back; or maybe it was a deformed/damaged clutch fork as I remembered having some difficulty getting the slave in place with the available clearance.
It slowly became stiffer and stiffer - eventually grinding a little bit into Reverse/First if not delicate with your shifts, but always drivable. It sat for a year or so and then was moved, under its own power, into my workshop about 6 months back.
Yesterday, I went to move it out of the shop, only to find that when I eased out the pedal, the clutch did not engage. It will shift freely with the engine running between all gears, without depressing the clutch - only a slight grind going into reverse. With the engine off, and the tranny in gear, it will turnover without moving the rig.
So what are your thoughts folks?
I was expecting a progressively stiffer, more difficult clutch and further uncomfortable grinding - but now it's 100% the opposite.
Obviously I'm going to have to pull it all and replace the clutch - but what else might be grenaded in there? Sheared input shaft on the tranny? Mucked up or chowdered flywheel? What should I be prepared for? What have you all seen/experienced.
Additional Symptoms:
1. For the better part of 15 years, from a stop - under heavy load - or downshifting in an emergency, there has always been a bit of a screetching/grinding noise. It has been a consistent noise and was unchanged in frequency or onset throughout this time - only under heavy load...
2. The last few times I drove it, it was stalling now and then but this seemed symptomatic of it being overdue for a fuel filter change and sitting for a long time.
Additionally:
1. If you're chiming in here, let me know your favorite clutch/flywheel on a modest budget as well - I'm in the process of prepping the truck for sale, so I want to give the next owner something worthy of the vehicle - but I'm not looking at it for myself or any specific purposes anymore.
2. If I need a tranny - who's the go to for rebuilds online - or someone local up here in Oregon. I'm out on the remote central coast.
Thanks for any feedback!
