I'm just having the fortune of experiencing the no start issues. I've had my M998 a couple of weeks, the one good thing about it was how well it starts. Then today I need to move it and all of a sudden, the PCB just clicks when you try to start but nothing from the starter. I hooked a slave...

I've got a M998 and want to get just a little more ground clearance. I have a friend that has some 40" tires but they are 15.5" or 16.5" wide instead of stock 12.5". I don't think I really want any more width but what others are going using if they are going with bigger tires. My setup has...

Just an FYI for anybody wanting to know the weight. Standard 37" tires, I do have the side rails and benches in the back and two people were in the unit on the scales. There is an OLD scale house close to the house where you have to weigh on axle at a time. Front was #3,300 & rear was #2,360...

1992 M998, yesterday I stripped the inside of two on mine trying to get them out. Anybody have a retail parts store # on these or would these be same as a 9x Hummer H1? Thanks Additionally, what do you guys do to get these out. I should have tried some heat I guess.

Trails around here have quite a few rocks and looking for something to protect body. I've found some places that sell H1 Rock Rails. Curious as to what others on here have done? Also, thinking about a skid plate for the bottom. Thanks in advance for any info.

Part # on mine is 23500012 (What I found in another thread was not correct.) Haven't had any luck finding one of these. Searching for an hour, found a couple of threads where people have had the same problem I did. Bottom bolt was welded to the threads of the crossover. Trying to change the...

I've been searching through a lot of threads on here but wanted my own for opinions. We picked up a couple of M998's and a few have water in the engines. They have 6.2 engines, but have found some take outs complete 6.5's & 6.5 turbo's. We'll probably use these mostly for 4x4. My preference...

Just got my first M998 home. Installed new batterie and Iit started up smooth as silk. Engine sounded good and smooth just no oil pressure. No smoke or blow by that I see. Not sure it's a sensor or something else. Oil level is good. I hope to look at it tomorrow. Anybody else had this...

Picked up 2 5 ton's a couple of months ago. My 923 had a violent vibration around 45 mph and then 60 mph. Not a axle hop but more like a dog when trying to wring itself wet. It was about to the point sometimes I thought it was going to shake the windows out of the truck. I was told it was...

As the title states, we were reading through a TM and I've searched on this forum and it appears the axle shafts are different between all revisions. I'm looking for information on the axle shafts. We have several 998's ranging from 88 to 92 and we're trying to figure out the part numbers and...

There was another thread but the OP got excited when somebody posted on his thread so I'm starting my own. Don't care about any type of "bullet proofing" but looking for legitimate options. Has anybody ever tried to use H1 doors on a 998? X doors would probably be the preference but would...

Had a friend bring over a 998. We were experimenting on some obstacles I've built for my Polaris. Same as with my M932, the M998 we noticed appeared only to spin the 1 front and 1 rear and most times the one with the least weight on them? Is there a way to lock in the axles, front and rear if...

M932 & M923, I thought these were actual 6 wheel drives. Got in some soft stuff today and disappointingly all 6 wheels weren't pulling. Looked like limited slip? Am I missing something, is there anyway to lock in all 6 wheels? (

Need to pick up a M998 in GA. I also need to tow a propane truck down which is going to require a 25-ton wrecker. I was hoping to tow the one truck down and pick up the other one. However, I'm not sure the pickup platform on the 25-ton wrecking will work for the M998. Typically, the wreckers...

Has anybody ever tried to convert the battery disconnect to the old Catepillar disconnect? And then then converting the ignition switch to a caterpillar ignition switch? I know there are keyed switches out there but I'm thinking it would be nice to do something that works with my equipment...

Here is a quick guide to winch operation that hopefully saves others some time. The manual for this is tm 9-2320-272-10 Start on page 0016-4 for operation A winch image from the manual is at the bottom. Winches without a level wind or tensioner. Cable out The winch drum lock knob (#4)...

Finally found a 932A2. Trying to figure out exactly what I want to do with it. Pretty sure I'm going to bob it and eventually put 53" tires on it. Right now I'm leaning toward getting a bed cut down to 10 or 12' with drop sides. I really want to put a dump on it and a trailer hitch. Panning...

After an hour of reading through posts of varying opinions on NC, I'm starting this thread to document the process of what all is involved in purchasing, registering and driving a 5 Ton in the state of NC. If anybody has an FACTS which are accompanied by links NC statutes, please post. I'm...
