This is where the design of the chains come in, some are good on hard pavement others (GI issue for the deuce, anyway) are lousy, shake the truck to pieces. The type of chain pictured below should be pretty good on pavement, but probably cost a small fortune.

Re: RE: When do lockers outperform tire chains? Well, if you drive on a side slope this is often the limiting factor, the upper side will lose traction and you are imobilized....

RE: Re: RE: What does CTIS offer that you can Does the CTIS require specific maintenance? How important is the air dryer to the health of the valving? Is there a manual override (=separate system for doing it the old fashioned way)? Airing up/down on the fly is certainly a plus.

Re: RE: What does CTIS offer that you can Based on some posts on this forum (I'd have to do some searching), they have their share of problems with it also, but it is more manually oriented and it still takes a lot of time.

RE: What does CTIS offer that you can Keep in mind that the time to inflate/deflate is not much different from doing it manually...figure 15 to 20 minutes.

Re: RE: When do lockers outperform tire chains? ...or applying brakes lightly if not selectively, to the free spinning side.

Simple question, really, or is CTIS just another result of the "push button/let the computer do the thinking" mentality? A related question, is there a provision to manually air up/down the tires, like in a second valve on each tire?

To continue the discussion on differential lockers, under what conditions are lockers better than tire chains? Assuming that the time to install the chains is not part of the formula. I have driven my deuce in snow and mud with chains and would think that they will outperform lockers in many...

Yes, just follow the procedure for removing the head, don't turn nothing, lift it up replace O-rings and set back down.

Okay, more common than I thought, what about the FMTVs?

I have steering knuckle dust boots for these trucks, sealed in bags, dated 1/05. NSN 2530-01-125-9272. Item #23 fig 111 in my 1988 TM 9-2320-272-20P. $15.00/ea ($25.00 for a pair) shipping included for the US....

HMMM...okay, thanks, my parts TM does not mention M939 on the cover, it starts with M923 (Sep 1988) and M939 is not mentioned anywhere in that TM.

Stupid question....my TM 9-2320-272-20P manual for the M923 5-ton truck series does not cover the M939, isn't it part of that series?

Locking differentials are such an advantage off-road, why so few US military vehicles feature them is a mystery (to me anyway). Is it an operator problem? How about a list of vehicles with limited slip or locking diffs, please.....

RE: Tires Always good to see a post that makes sense, thanks Poccur! :-)

I have the operator's TM for that engine, TM 5-5208, if you are interested. Its only 24 pages, but appears to be original and in excellent condition. Dated Nov 1952. $10.00 postage included..... Kipman gets first crack at it in case others are interested.

I don't think this would be "hi-jacking" your thread, but another huge pucker factor on my '68 USMC M49A2C was discoverd when I replaced the front axle seals some ten years ago. The nuts holding the spindle (12 ea) were of a very soft grade, as a matter of fact several were stripped of their...

Those bolts were loose on my M49A2C as well when received......
