clutch just quit

Hey man I am in need of some help. I have a 05 4.0 six speed and the clutch has felt fine no problems pulling my boat or anything. Went to pull my boat out yesterday and it would not even go into gear to move the trailer. Hope one of you guys can help i am at a loss of words on this one it was just random.

Open your hood and look next to the master brake cylinder, see the little one, unscrew the cap, see if there is fluid in it. If not you have a leak in which case you will need a new clutch master cylinder, it's a 20 minute job, the new ones from quadratec come already filled and assembled. You just unbolt the old master from the firewall, unbolt the slave from the bell housing and bolt the new one up, drop it down after gently uncoiling the new one and bolt it back up. That is the most likely cause, keep the new hose away from the exhaust pipe, it will melt a hole in it. You can buy a separate master and slave but you will have to fill it and bleed it, easier when it comes as one prefilled unit.

That was one of the first things i checked and it was full of fluid. That is why it just does not make any sense to me at all. Thanks for the help though I was hoping it was one of those stupid common things with a easy fix, guess I am not that lucky huh.

will it shift thru the gears with the engine not running & the clutch pushed down. Don't know if there is a inspection hole or anyway to look inside the bellhousing on a 05 ,if there is maybe you can have somebody work the clutch while you look & see if it is working. Make sure park brake is on &/or wheels chocked. Possibly the pressure plate ???? maybe the fork for the throw out bearing. Not entirely sure how everything is setup on a 05 but is it possible that there is a pin on a rod at the slave clinder or something there that is not letting the slave cyl. push the throw out bearing in.

yea it will go through all the gears with the engine off and if you leave it in gear and start it the whole truck moves. somebody told me there is some type of rod or piston that causes the clutch to release so maybe that is it I just don't want to have to drop the whole thing if I can avoid it. I have search for common problems like this but have found none. I would like to be able to look at a schematic of the clutch just to trouble shoot the small stuff first anyone know where to find a breakdown of that. Tired of bumming rides

I agree if you can watch the clutch fork to see if it compresses the pressure plate while another person pushes the clutch then I would say check that out real good.If it has to be a one person job then I would say put it on a lift and pull the slave cylinder off and push the shifter fork in with a large screw driver to see if it has any resistance.If it don't have a whole lot then the pressure plate has gave out if it does then look and see if you see chunks of clutch fiber.

Hmm, was it really hot at any time ? It's possible you have moisture in the fluid and when it get boiling hot you end up with steam in there. Either that or something is sticking, don't know what but if you are around salt water anything is possible. I do know that driving on beaches and in salt water is a very fast way to eat bearings and universals.

Yea it was about 98 degrees out and I got it wet when I put my boat in so that could have been the problem. Hey its the best kind though you know the ones that take care of themselves

I'm mite dubious about getting saltwater in there, I've seen what marine corps m151's looked like underneath that they used in beach and amphibious operations and man I gotta say it's nasty. I drove one during an joint army/navy/usmc training operation and the water was up to my waist in the driver seat for about 5 minutes from when I pulled down off the ships ramp till I got up on the beach. Talk about wet ass.. maintenance sgt told me that after about 5 years of that they just fold in half from corrosion and rust. One rule though was once in the water DO NOT disengage or engage the clutch, if it's in leave it in, if it's out leave it out. You can actually start an M151 in first gear with the key and it will buck, jump, get pissed off but it will start and get going.
