I was in the process of raising the cab of the M1078, when just starting on the way up, the cab latch cylinder blew out, spraying hydraulic fluid all over the right side of the truck. The oil came from the indicator plunger, which we are supposed to look at to make sure the cab is latched down...

Be advised, the rebuild kit for these is not simply standard o-rings.

There is a place local to me that sells the kits for $20

I'll PM you the link (the mods don't like links in here some times unless it's sponsors)

I could use a set for mine too it blew the same way.

Scott has then last time I talked to him:

LMTV Cab Latch Seal Kit, Advanced Automotion

Got the nut off the Latch today. Found the seal that blew it is the smaller inside O-Ring. It is missing pieces on the O-Ring had to take a picture inside it to see. I can see the hydraulic fill orifice to make it work. The fluid was coming out where I could not see the source till now. It was not coming out the nut by the pin. Big O-Ring sealed OK I think it is new looking may be why the Military sold the truck latch sticking? Now need to remove the inside parts left with a curved pick and put the new one in. That piece is from the outside wiper dust seal the pin goes thru. I took a few pictures of the progress. Need to clean the parts better but test fitted the O-Rings except the inside one.

Appreciate the pics.

I have a kit and need to rebuild my M1079 that's pissing itself.

I got the kit and removed mine completely from the truck. Spent time cleaning and inspecting it.. its worth the effort to really clean it well. Also purged some fluid through the lines to get gunk out.

Don't forget to pre coat everything with fluid when you put it back together.

Had to burn the Hydraulic Fluid off the Exhaust Pipe so I went for a drive! Still have to have fun too with the truck! Just took a 10 mile drive around our Loop Road. We still have some trees left after the Wildfire went thru here Sept 7th 2020. 19 years after the last big one went thru. Both time real scary we stayed to save the animals and our place. Work to hard to go to town and wonder?? My Daughter had all the new Fence put in after the fire. Last 3 pictures are of our place.

I love that place... Looks so peaceful. Bet it isn't when a fire is running up that hill, but otherwise nice!

Definitely have to go for a spin around the block every now and again.
Loop Road sounds like good spot. Long enough to go for a ride, short enough that home isn't too far away.
Good all around!

 

[JD4044M]

Thanks! We love it here too and it is quite. On the Loop Rd I can do 50+ MPH tests on the flat asphalt
and the dirt road has some sharp turns, steep hills and great views!

Now I need to get all the Hydraulic Fluid off the back of my Cab and Frame. Any ideas that work and not screw with the paint?

A can of spray degreaser and a pressure sprayer should knock it right off.

Could be that Joy dish soap would work.
If it works getting oil off ducks, maybe it would get oil off a big green truck.

Maybe a weed sprayer mixed with hot water to load up the back of the truck,
then spray it with a hose? Less chance of attacking the paint maybe?

 

[JD4044M]

Thanks, OK Dawn Dish Soap first, Hot Water and my pressure washer in rinse mode tip since it is a 3800 PSI one! I will try some engine degreaser on the frame stuff in the middle of the truck below the latch and pump. Going for another drive but picking up a Dad and a couple young kids and take them too.

Took a bunch of kids for a slow 18 mile drive today. They were inside the Cab and 2 Adults in the back. They had big time fun riding on dirt roads. Went and picked them up at there camp site. 6 of us total just driving around off regular roads. The Kids were saying wow this is the biggest military truck they ever road in!! It was the only one they have been in. I went slow and we drove on privet drives one I fixed. The owner said he wants to buy my truck if all go well in a few weeks? There whole place burned down but were well insured! Kids are sure different now days when you have 4 in the cab with you all asking questions and one telling me you can talk but keep your eyes on the road??
