2007 FG clutch slave cylinder frozen?

[pugslyyy]

Anyone had this issue?

I hadn't moved the truck in a while (started it but didn't roll it down the road because I had a lot of things loose in the camper).

Went to move it today, and couldn't get the clutch to work. Figured it might need bleeding since it hadn't been used - bled it just fine, but still couldn't get it to release.

I thought the throwout bearing and/or slave cylinder might have frozen up so I pulled the inspection ports, blew out all the cancerous dust (cough, cough) and beat on the eye bolt for the clutch hose which connects straight to the clutch direct power cylinder via a threaded pipe connector.

Anyway after a couple of blows with a large mallet, everything loosened up again and the clutch now appears to be working.

Anyone have similar experiences?

I seem to remember another post on exactly the same topic, but it was some time back.
Did a quick search but could not find it.

Thanks I'll see if I can find it.

Me too!

Just sorted this issue out yesterday.....

I had the same problem as the OP had and it took me a bit longer to figure out the problem but here was what I found:

1. Clutch not working, look at fluid, watch clutch master bending the mounting metal a bit so it is operational.

2. Under the truck I have my wife pump the clutch pedal and I bleed the system, no air apparent.

3. Remove the rubber inspection ports, two of them, and have my wife engage the clutch while I see what is transpiring, I see the clutch slave cylinder move and make contact with the clutch diaphragm springs which in turn move in the correct manner, but the clutch did not come off the fly wheel or whatever it is called now.

So the clutch plate is stuck to the fly wheel.

4. Try several things to free it up, start truck, get it hot, move it around, jiggle and move the truck, hit all the area with a rubber mallet ( mostly just in rage)

Nothing!

5. Get a dull cold chisel and BFH and give the clutch plate a couple of love taps while my wife works the peddle and lo and behold she is free!

6. Get in and drive around to make sure all is OK....check and note to self....Dont leave the truck sit for more than one month.

7. Take a breath and continue to get ready for a three week vacation....phew!

Sooooo.... it seems the clutch plate gets rusty and sticks to the flywheel.

Yeah, at least it is in the annoying category not the expensive category. I've had this happen a couple of time here in the hot and humid southeast. The last time was a bit annoying because it was stuck in gear and I had to use a comealong to unload the drivetrain before I could do anything with it.

well its only in the annoying category while it still comes unstuck, I had different visions in my mind prior to that and they weren't so appealing!
Inside the housing there is a lot of rust as I too live and a moist environment and I guess all the particles get moved around in there and get over everything and it rusts up, maybe spray a can of WD40 in there, lol.

Yeah I'll be sure and do that the next time I hit the zerks on my brake drums.

When this happens on older 4by's if you put it in top gear and flick the starter it will usually be enough to free the clutch plate.

The Fuso is too smart for that. Has to be out of gear to be started.

Out of gear or just clutch in? (switch on clutch pedal)

I am pretty sure there is a neutral switch on the gearbox. It would not be a hard thing to bypass, should it be necessary.

WD40 on friction plates is a bad idea I would think. Glad you guys went through this before me so I can cut straight to the problem if it occurs. Best solution I can see is keep on driving!!! 😀

yeah it is right on top of the gear box, slightly left of center

 

[westyss]

Hey that WD40 was a joke!

There is a switch to prevent starting in gear which would have to be bypassed.........but........somehow I did manage to engage the starter while in gear, it was odd and couldn't make it occur again but it did it twice on me, but that did not un-stick the clutch, also while the motor was running and trying out the clutch to see if it was disengaging at all I moved the lever too far and it engaged the gear and the truck lurched forward then stalled, that event did not loosen the grip on the flywheel, so both were tried and no joy hence the cold chisel route, ya the best solution is to drive it all the time which I will be doing tomorrow!
