Crawled out from under my dirty bastard 88’ M998 I was cleaning/prepping for paint to finish up renewing these beauties.. Ocho

Well, to add to my plight.. I also have another radius tube I ordered months ago, and it is even shorter than the 10.87” model..it’s like 8 1/2”... My front radius rods are close to the 10” rods, but my rears are definately 12”.. guess I’ll do some calling around .. feel free anyone to look...

Yes like that one, if that one is 12" and not the 10.87" that I've been finding everywhere. Im just concerned with the shorter length because my rod ends will most likely only screw into the radius rod up to the far end of the relief cut and not completely into the tube.. Not sure if it...

Tearing down rear end on the 88’ M998. Want to replace the rear radius rods because one is bent and one has some bad threads... So I can’t seem to find anything longer than 10.87” as a replacement.. The ones on my rig are a solid 12” long.. Has anyone else had a problem with this or know...

Transmission modulator.. has o ring that might be leaking where it goes into transmission.. Can remove bracket holding it in and slide out to check/replace O ring.. looks like housing may be leaking though because of the bit of RTV smeared over it.. easy enough to get a new one and replace...

put in an air ride seat :ROFLMAO:

Tore down, rebuilt... now I can finish putting rear end together..

Im just tossing my 2cents out there. It took me 5 minutes to figure out the engine I had after I received mine.. Id say look harder and do some research..Plenty on here..

Perhaps an early K5 heavy duty tranny... Big maybe on that

It is a 5.... a 5ver...5ish....Definately a 5 !!!!

This is what a forum should be like 👍🏼👊🏼 Since I’m working my way around the HMMWV, cooling system purge and clean are close on the agenda.. I’ll probably pull stack so I can thoroughly rinse out the radiator. Also need to do some brake work up front anyway with some odds and ends.. This will...

I said re-manufactured...Id say its a pre GEP that got overhauled and put back in service.. GEPs were probably to new in service to be yanked, overhauled and put back in a vehicle in 2010... Just my thinking though... Are there any Navistar markings in your engine valley on top ??? Find em...

Thats a NSN for a Remanufactured 6.5NA that they musta swapped in

HAve at it... that’s what they are for.. and if you come up with any “ Mods”, please share.. we are all usually trying to improve or upgrade our rigs 🤘🏼

I think Paradox By Design has a kit to move coolant to back of engine block to help with cooling it.. Fairly cheap but not sure of results personally.. Take a peak.. Ocho

yes yes yes... you guys jump all over crap.. Im not having an issue troubleshooting fan clutch or overheating or anything else. Ive memorized all the 2800 pages of TMs.. And I dont think whacking the metal clutch to un-stick it is in there (Camo :ROFLMAO:) Maybe you have access to the redneck...

So got the 1988 M998 fired up last month. Run it in 10-15 minute intervals to keep battery's topped and get to temp. Noticed my fan is engaged and wont disengage when I unplug my Caddy Valve..I can see its working because hoses flex under pressure. Any good fixes for stuck fan clutch??? Can...

Out of his league??? Had HMMWV for 5 years and not sure how anything works... Wow.. Radiator fluid.....That would be COOLANT.. Must be an Oregon thing. Id say you best pay VERY CLOSE attention to everything that is in this post.. YOU will need it.. Test your sensors, make sure your...
