LMTV help with hood-cab release

[raxter111]

Hello, i cant get my hood/cab to release and its pouring fluif when i mash button to raise the cab. Any suggestions?

Where exactly is the leak?

Typically, it's at the truck-side (not cab) and you can see it misting out.

Here's the kit if that is where the leak is:

LMTV Cab Latch Seal Kit, Advanced Automotion

To raise you cab, fill the lower (manual) reservoir first then the upper. Place a towel over the source of the leak (kiddy pool under the truck if your one of those environmentalist). Cab should raise, repeat as needed.

Thank you, where is that lower resivoir that your talking about? near the manual pump? and the upper is the treadle pump?

Also, i beleive its the lock thats not unlocking so the cab will lift,just wondering how to unlock the lock.

It's under the manual hand pump.

I may be mistaken here, but I'm thinking that the cab lock won't release w/o hydraulic pressure present.

The little red tit indicator on then latch will pop in/out.

Yep, you need hydraulic pressure to release the cab latch As it is “t”d off of the lift feed-line to the cab cylinder. what happens is the o-ring seal in the cab latch piston lets go and all the pressure escapes there and the latch won’t open. So you need to ID where the leak is.

If the cylinder is the issue, you can disconnect the line and cap it, then the latch cylinder unscrews with a large socket. Then you can pull/release the latch mechanism by hand and pump the cab up to get it out of the way While you overhaul the latch piston...

Or I've heard you can unbolt the catch from the cab as well. Might not help with building pressure in the lift cylinder though.

Just went though the same problem your having now.
So, how did you do? Get it working?
