[Augdog1964]

Hey all,
My M1120A4 HEMTT LHS is having an issue where the LHS system is not moving...

In dire need of the Maintenance and Parts manuals for it.

Also if you were a maintenance tech on these vehicles, very interested in talking about this...

thanks

Dave

Might help if you list what TM's you want.

No idea what the TM numbers are. Only TMs I can find are for the Operator Manual, which I have. An online look came up with nothing, before I posted.

Ill check this afternoon and see what I can find. Does it run the standard hydraulic systems that the PLS A1 run or is it different?

Well, if you have the operators Manual, (-10) then you have a starting place to TM's that you need. If you would look at the Appendix A, in the -10, its a list of documents needed to operate, repair and order parts for the truck. That should get you going. Also remember that some TM's are not coded for release to the public. If the TM's you are looking for are not coded "A", then they will not be real easy to find, and can not be posted in the forum. If you would have posted at least the Operator TM number, the search would be that much farther on.

The Operator TM is 9-2320-345-10

Is this the NSN on your truck? 2320-01-492-8221
Whats the date on your -10 manual? and is there any changes to it?

Hey all...

Ok the NSN on my truck is 2320-01-534-1872.

She's an M1120A4 built in 4/10.

Date on my TM is October of 2008.

Here is where we are today after a whole day. We have the dump truck bed working. HOWEVER we have two issues with the HEMTT in working with the bed:

1). In order to get the bed going up and down, with the dump bed hyd connected to the Quick Couplers on the HEMTT, we have to "force" the hydraulic by having the main hyd switched on, and pushing the LHS joystick up for loading.

2). When we turn off main hyd, and select AUX HYDRAULIC which we believe should run the Quick Couplers, we get no hyd pressure.

3). When we plug the load sense into the hyd pump, we get no hyd pressure using main hyd or aux. and the LHS system does not operate.

We are basically stuck w/o a technical hyd and electric schematic, or someone with some experience on this hyd system.

Thanks for any help! Pic attached:
