Is it a bad idea to reuse the brake line fittings off the old lines when doing a complete brake system overhaul? I've cracked 1 fitting before when I was trying to loosen it, darn gorilla hands. If one cracked under pressure that would certainly be a bad thing on a single circuit system.

I noticed most of my 60's dated 9.00s have a sharp, squarer tread to them. While the newer tires (80's) have the typical round tread pattern. Also, anyone know the reason for the variation in tire pressure? I know the rule of thumb is to go by what the actual tire reads. My 50's TM manual states...

I thought you GMC nuts would get a rise out of this. It's called a Futurliner passenger bus. These were made by GMC Truck And Coach, the same people who made our GMC trucks. Powered by the same (nearly anyway) 302, the exact same Hydramatic but also backed by a 2 speed manual for a total of 16...

I just stumbled onto this vehicle today online. Wow! A 24,000lb truck all powered by the GMC 270. The spec sheet states 91hp and 216ft lbs. Gotta love the old school way of thinking and doing things, small motors and lots of gears to get the job done. We are spoiled today, 500hp 1 ton pickups...

Great reading material for anyone who's a 6.2 fan. http://www.hotrod.com/pitstop/hrdp_1009_6_or_8_inch_balancer_for_small_block_chevys/viewall.html

The M998 manual states the NA 6.2 makes 150hp at 3600 and 260ftlbs at 2000rpm. Wikipedia and ForgottenDiesels page both state the "Army" 6.2 makes 165hp at 3600rpm and 330ftlbs at 2100rpm. Why are these numbers so far apart?

I have heard of .030 over during engine rebuilds, but the rebuild tag on my 6.2 HMMWV motor states it was bored .30 over. Does the rag really mean .030 or .30? I don't think it's even possible to have any cylinder wall left with a .30 bore over. That would make it a 7.1L diesel. :lol:

Thought i'd share this article I found, i've seen it posted years ago but the link was dead. Thought i'd never be able to find it again, but it's a real nice read. Makes me love my GMC that much more........ as well as the Th400 in it. rofl M211: The “Cadillac Deuce” | Military Trader

If you like fabricating stuff as much as I do, I think you'll find these clevis forks are a neat thing to have laying around. I have some transfer case linkage to fab up to shift my Tcase into reverse since the original linkage is not compatible anymore. I searched for ever trying to find out...

This is often an overlooked part of repowering these old GMC's. But it is vital to the life of your transfer case. The GMC tcase engages the front axle automatically, when the rear tires begin slipping (around 6% faster than the front). When traction is regained, the front axle is automatically...

Something I never thought of before, as many of you already know I just installed a 6.2 in my M211. Just how loud is the cab going to be? I know a lot of 6.2's sound like a washing machine full of ball peen hammers. And I will be routing a single 3" straight pipe up the right side of the cab...

Anyone know who sells the air cleaner housings for the 6.2's? I just can't find them anywhere, i'd like to get the cottage cheese lid off my intake. :lol:

I was wondering if the Multifuel turbo could be used on a Military 6.2? Why would and why wouldn't it work? It would sure sound sweeet.

How often do you guys find your using low range on the road? Loaded or unloaded. Say you have 5000lbs in the bed and your on level ground, is low range usually necessary to get moving? Just an example, of course.

I was hoping somebody could help me date my 6.2 HMMWV motor. From all the searching I did I didn't find much. All I know is it falls in the 82-91 category. Block # 1402260 No julian code on the bellhousing flange. Just numbers "231". Heads are 10137567 Lastly, the smooth section of casting...

Was wondering if anybody could explain how lower differential gears can lessen the load on engines and transmissions, effectively prolonging their life? Just curious is all. :D

I just picked up a roll of this foam at home depot yesterday, in the isle where they sell doors, trim, springs, hasp locks, etc. Only I got it for under $4 a roll. This exact size will work to replace all the weatherstripping on my GMC cab. I see no reason why it couldn't be used on the M35...

Original NOS weather stripping is impossible to find, M35 series weatherstripping does work and is widely available, however from what i've seen it takes over $300 to replace everything. I can't justify that. $300 is 6 new tires for me. I found this stuff at home depot while cruising around...

I live in Yuma, AZ where it's about 110 in the summertime. Can the 6.2 run on a 50/50 diesel/WVO mix in this temperature okay?
