That search may be of some help. Thanks. In post #11 by nf6x he shows two pics. The top one is on his 936 the other a 543. My 936 has the same pump as his 543. So the pic of the tag should be my model number. Mine is leaking where you see the the 4 point shaft sticking out of the motor. That...

A&L is one of the places I will go to. They fix my frame machine pumps a few times a year. I just thought it would be an easy part to get. It is such a poor setup I figured it would be a common seal. Brian G.

I tried that but could not find the exploded view. The winch motor is the same M543 and up. I have called every MV parts place I know and none can find the parts I need in the TM. looks like I will have to check some hyd. repair places or I'll have the cover machined for a common seal. This is...

Thats part of the problem. I found the exploded view in TM 9-2320-260-34/2 figure 20-56. This is a 800 series TM. The motor is the same. When I found this page it seems like the next pages that would have all the NSN numbers that would match this page are not coming up. So I have the view but no...

Last week I was using my 936A2 and the boom winch motor started leaking where the manual shaft comes out the rear of the hyd. motor. The motor comes right off, less than 1/2 hour and it was on the bench. I pulled the front cover and found the seal that is leaking. Now the fun part. There is no...

I just did the same thing to my 939A2. Turned up the pressure at the regulator then unpluged the cable. Put the cable back on and it all came alive. Air started cycling, I hit the sand button and you could hear the air coming out of the valves. Then I hit the highway button and it aired all the...

70deuce. Thanks. That looks like a great start. Brian G.

What TM # is the trouble shooting in. I would like to fix the CTIS in my 936A2. It too worked when I bought the truck. No idea why it stoped. I have not mastered the TM's yet. If someone can just guide me to the correct one would be great. BG

My wrecker shakes around 50 MPH. My cargo dose not. The cargo has counter weights on the front wheels, The wrecker dose not. I think thats where the problem is. Do you guys with this problem have the counter weights on the front wheels? If not I think we need them. As for the clunk you here when...

In the early 90's when my brother and I had our M543's we bought two WWII air port snowblowers at auction. We towed them about 25 miles back to our yard with the Mack powered M543. These things where huge and heavy. The blowers where powered by giant gas motors mounted on the back. We lifted...

I have a RRAD 2011 overhauled truck. I have to say theres no way you can call it a rebuild truck. Looks like most of the truck was sand blasted and painted. No grest job either. All new tires which is nice. When I got it home the batterys where up and it fired right up. Runs down the road great...

Mine too. I turned the fuel srcew out 4 turns. Very little smoke and much better from a stand still. I just drove it this morning. I have to say mine is a very good running truck for a wrecker. Big diff. driving my cargo. The cargo truck feels like a race car after driving the wrecker. But...

1 open your floor vent. 2 Pull the cotter pin out of your door check. The little rod that stops the door from opening. 3 Reach your hand in the outside vent door and pull that door check out. 4 Pull the rubber stop off the rod and install a 3/4 inch spacer. You can use a nut or an old upper...

Yea mine is the same as yours. Rolls along at 55-60 on the flats but it dose not like grades. Rides very well due to how heavy it is. The cargo truck is much stiffer a ride than the wrecker. Mine came with all the same tools. Those giant snatch blocks are way to heavy for me to ever lift. Even...

After Driving the two back to back all I can say is what a diff. This cargo truck is like a race car after driving the wrecker. Now I know the wrecker is 15000 pounds heavier than the cargo. The cargo is very nimble. Handles very well. And will leave the wrecker in the dust. This cargo pulls a...

The link is perfect. Good info. Thanks Brian G.

Whats the deal with Hawker batteries? Are they a gel type battery? Is there anything you need to do diff. to charge them? I ask because the 5 ton cargo I bought last week is now home. It is an RR rebuild done 11/11. The truck is like new. The batteries are fine and it started right up...

After first inspection I found the brake light switch unpluged, Why I don't know. Both the lift pistons on the crane had the lower pins that hold them in place pulled out. They where laying right there with the retaining bolts. I had to lift the boom with my fork lift and just install the pins...

Welcome to the wrecker club. I bought mine back in Aug. I thought I got a good price. You did better than me. Mine has all the BII kit in it. I got lucky and it only needed minor items repaired. Good luck. Brian G.

Suprman. We will see if it is as nice as your tractor. Your truck is what pushed me over the edge. I met Suprman last summer at a local cruise night. I'm driving one of my Vettes and he pulls in with this like new 5 ton tractor. I had to go look at it and started talking to to him. This truck...
