I have a M998 that has no c pillar and was a soft top. I'm going to cut down the b pillar 1/2" so there is no rise from windshield frame to b pillar. Found a shop that can use a press brake to form the radius on edges about 6". The issues is I can't find aluminum sheets wide enough in 1/8th...

Moving batteries to right side air lift and I have 5.5 inches of clearance from wheel. What is the the suspension movement range? I have some more room to move up if I trim off the top of box before the front battery gets to close to the hood.

After a few months of part time working on it and research on this site and others. We have a running engine. I believe it was stuck rings not providing enough compression. Marvel mystery oil thru glow plug holes with syringe, crank a few times , let sit for a day , repeat. While cranking...

I'm looking for a better compression tester to borrow, and thought about the oil trick. Any particular type or weight.? Thanks

M998 compression test - No start Gov Planet purchase , no start and knocking on cranking in description before I bid. I've finally got a compression test and have low of 60 psi and high of 240 psi on cylinders. Harbor freight compression tester for gas motors only goes to 300PSI, but I...

I took off the water pump to check the timing marks and they are good. It is vey clean behind the plate that holds the water pump, which leads me to believe that this is a low mile motor, 3300 miles with a rebuild date of 2006 in Maine. Would a shot of either in its earlier life take out the...

So after much research, got a compression test gauge, for gas engines, only goes to 300 psi, but I used it. It had the M10 thread fitting to adapt to glow plug holes. Took out all the glow plugs, remove wires from injector pump and let it crank. I got a high of 230, a few at 120 and front...

I just used that as a reference to start with.

Can someone describe what the fuel pulsing out should look like when line off at injector and line off at back of injector pump?. I still may have air in the lines, but I've tried a few different ways to bleed air. Thanks

Thank you, the old one went to a diesel shop and was diagnosed with a bad head and rotor. I got a 5209 pump rebuilt from Hummer parts guy , I will research the cold advance switch. I still have the manifold off, I'll put it back on also. Got a little more black smoke coming out of tail pipe...

I’m going to try the valve stem in the fuel cap to pressurize the fuel tank. I’m drawing out of a 5 gallon can belowthe lift pump now. I drained all the old fuel out of tank put in new plug. Let’s see if that works.

Going to have to call in the experts, or the diesel shop down the street. Still no start after new injection pump, new S3 start box and TSU, new glow plugs, two new batteries and grounding harness. Old db2 injection pump tested bad at start rpm, got a rebuild from Hummer Parts guy...

The shop charged 200 for testing. I'm fine with that, but they wanted $1,700 to rebuild.

Injector pump tested bad at start RPM, needs new head. I going to look for a remanufactured one. Any ideas where to shop online? It's a 6.5 NA, I see two types for 6.5 The NA's and the Detuned?

I'm in the process of getting mine running with 6.5 and titling for on road. Interested in duramax conversion also. Headed to Sema this year and Hline conversions has a build for SEMA 18, I will talk to him in Vegas.

History of mine.. 1986 with rebuild in Maine in 2006. A sherifs dept. had it until '14 or '15 registration on floor had there name on it. I called them and they said it ran fine when they had it, and then went to a Forestry dept. and then made its way back to Iron Planet. Date code on 6.5NA...

The plan at the shop for the IP. Open top and check for corrosion, if clean inside , they will put on test stand. Hopefully it is bad, this I think is my last option for no start. New glow plugs, new S3 here this week. When I had 4 of the lines on the top of the injectors off while...

New S3 box with TSU on the way. Stanadyne Injector pump out, and sent to service center in PA. for test and rebuild.
