An addendum, advantage of a fluid damper is that they do not wear out or slip-at least withing the life of the rest of the engine.

Ferm is right on, let me expand it a bit. When you balance the crank on the machine it is a static balance for that rotating mass. To achieve static balance you need to have all rotating elements installed. It is assumed that the elements are static in nature, in that, they do not change...

OK, might be some truckers that can explain it better but they can slide hitch and axles, you can't. Go weigh both ends of the truck empty with a known amount of gas. Gives you a start on it. Trailer load weight should be over axles not at the ends, opposite of semi trailers cause their axles...

Forgot to add, with 373's your tranny is what may need xtra cooling. The diffs have enough miles on them so are not likely to over heat. If you have posi try not to spin a tire--you could burn out the clutches.

Here as far as I am gonna go, 10k ball is one thing, hitch rate is annother. If you exceed either one you may have your trailer come loose or bend things. Consider that a dead weight pull is very different from the shocks of down the road travel. BTDT, had a 36' Bounder on a GM P30 with a...

Last fifth wheel I had said 6500 dry, no genny. About the same size as yours, with all tanks full of water--main, grey and black, added an Onan and gas plus propane fill up...actual across the scales at 8955---BEFORE it was packed up for a trip. By the time my wife and I got done, 13620...

One of the boom box places should have antenna adapters--and prolly coax splices.

I went thru the master RPO book for GM and found these 6.2 and 6.5 diesel engines: L12 DI OHC Turbo ???????? L49 Non Turbo L56 Turbo EGR L57 Non Turbo HO L65 Turbo HO LL4 6.2 HD LQM GMPT 170 hp LQN GMPT 190 hp There was a 120 hp "fuel miser" version for P series delivery trucks but...

Ferm, what's the "mechanical Turbo" version you mentioned for 92-93???

Guess that fixes the "rumor", thanks Drago

Not quite so fast, per my sig truck, it is tagged for 9000 GVW, and 17000 CGVW. Hitch is rated for 10000. The RPO codes are listed for mine--that kinda means that the parts are available from GM, OR, you should be able to do your own upgrades to at least that level. Big difference per GM is...

BTW, check your RPO codes for any chassis upgrades, mine surprised me.

SRW not a dually, as in single rear wheels

'94 L65HO with 3.73 gears, the "HD" 2500 is rated at 13k with AT and 11k with MT. That's combined Gross, truck and trailer max. Hitch or 5th wheel towing you are at 7k for the trailer with either tranny. Per GM.

Two 6.5 turbo versions, with egr 180 HP, without 190--referred to as the 'HO'--in the 8000 LB and above.

Actually, I think Warwagon had the easiest way to run the pump without the key on in start--on the ODB1 connector there is a red wire, jump that pin to +12 from the fuse box and the pump runs. Wiring diagram calls it a Priming circuit but does not show where it goes---I don't remember which pin...

I found this chart, hope it helps.

Two reasons for them to be different, the ecm reads a different sender, the sender is in a different place. The gauge sender does not affect ecm operation.

I don't have a diagram of the cluster but I think these are like most---just an analog gauge with sender to ground. May have scaling resistors. Sender changes resistance with temp--changing the gauge reading. Per post 9 I found senders varied in resistance at the same temp. If your gauge...

Slug, Sender is pretty cheap. The resistance does not match the chart for the IAT and CT used for the ECM tho. I only care about the center of the scale---like where it shows it's too hot. Have noticed these have alot of Tstat bypass and warm up pretty slow, mine seems worse with the heater on.
