Match your revs? You can shift without it. That's assuming it's locked engaged

Try and fix it??

Is it the pedal that's gone wrong or has the slave cylinder push rod punched through the clutch operating fork?
If it's the latter then you need a new clutch fork and while the engine and transmission are split you may as well throw in a new clutch too.

A tow truck might help to get you home

The clutch pedal won't move at all. If I crack the line on top of the clutch master the pedal will go down. As soon as I tighten it, it locks back up.

What happens if you crack the bleed nipple on the slave cylinder?

Or pull the slave cylinder and see what's occurring.
What sort of milage does the clutch have on it?
My bet is still on the fork or the spring plate breaking up
Good luck.
Hope you get home OK.

Good call,
The rod that goes to the fork is much further into the tyranny than it was on my other truck. It doesn't seem to floating around in there, its just further in.
The clutch has less than 20k on it, but I didn't change the fork on it, luckily I did on the one in my 110

Thanks, I always change all the components that go with the clutch - pressure plate, friction plate, release bearing and release fork, they all have a finite life and don't last much longer than the fiction plate.
I once ( as a penniless youth) opted to change only the friction plate. You guessed it - a few thousand miles later I was in there again for the pressure plate.
You can reinforce the release fork by welding flat bar across the fork to support the point that the clutch rod pushes on. That's the point yours will have failed at.

Make sure you reinforce the fork. You don't want to do it again. Another good upgrade is the aluminum housing for the release bearing.

Can I just drop the tyranny? Or is it easier to just pull the whole engine.

Tempted to have it done in a shop, a bit afraid of the price though.

where do u get the aluminium housing for the release bearing? I saw one included in a britpart HD kit, but I read those kits were for shit.

I believe you can pull the engine forward about 6" if you take the rad shroud and fan off. That apparently gives just enough space to do the job. So a mechanic friend told me. Failing that I'd pull the engine. Luckily or not, I've not had a clutch fail on it's own. I tend to put a new clutch in when it's all apart for something else such as a gearbox or transfer box or a full rebuild.

Are you certain it's not the slave cylinder? I have heard a few people have had problems with new ones seizing.

I think it's diagnosed as a failed clutch actuating fork. Not good but it happens.
There are ways of preventing it happening either by strengthening it or putting a new one in when the clutch is changed.

Tom can you pull the push rod out from the bell housing and maybe look in to confirm that it is indeed the fork that's failed?
Are you going to change all the clutch components while its all apart?

Probably, it sucks because it only has about 20k on it.

If the fork failed, why does the slave rod not move? I would have thought the clutch pedal would go to the floor.

No it extends all the way and the pedal is hard as a rock. Been there, done that got the T-shirt.

Without a lift, the engine is easiest. With a lift, then the tranny.

Do it yourself. It is very easy with this engine. 4 hour job with a friend. 5 to 6 hours by yourself. No special tools needed. I just did the same thing in October on my truck, so I'm speaking first hand here.

Oh, and make sure it in an OEM clutch fork and then put a backing plate on. The OEM ones are actually made with hard steel. If you really do not want to see it again, run in a grease line.

I can get it on a lift at school, so I may just drop the tranny. Should I replace the less than 20k clutch?
