Hello gwbaker ,

your doing a great job there ,As a proffesional mechanic /technician by trade
I can appreciate all the hard work there .And your right ,always have the donor vehical at the ready for ALL the little things you need ,and they will be many .One thing I will caution about is the use of that A/C condensor for a tranny cooler ,definately not what you want to use ,very restrictive ,and
will cause excessive pressure to build up on the inlet side of the cooler .Ive seen people use those A/C condensors and have major troubles .There is a flow rate for tranny coolers and volume tests that are used to check for restiction ,best to go get a big truck tranny cooler and use that instead .
you may want to install an auxilary electric cooling fan in front of your coolers to help with the temps ,either automatically engaged or with a dash mounted switch so you can turn the aux fan on whenever you want it .your condensor
is blocking all of the radiator in your photo ,you want the radiator to have some exposure to unobstructed airflow ,while maintaining a couple inches of space between coolers .Great project ,the engine looks right at home in there .

Hi Russell
Sure wish I was in Tucson right now.

If you see a 20 foot motorized argosy or airstream think of me.
Thanks for listening. - Flukewho-loveland,ohio.-

GW Baker,

I have a set of upgraded Henderson front springs that are rated for 5400-5900lbs. The good thing is that you no longer need the front airbags. I ordered these first but my 82 Classic needed the 4900 lb springs, so these have only been mounted used for one trip, then removed.

I will do you a deal on them.

7. no cruise control thoughts yet, but they have aftermarket kits i will investigate.
also installed boost, pyrometer, trans temp and fuel press gauges.
I am very curious how this works out. I drove a Cummins for years and always considered them the best. I now have the Isuzu in my 345 and find it about the same as far as performance. I do have the later model which has the bigger blower and other improvements and I get somewhere in the neighborhood of 220-230 HP. I get as high as 16mpg, depending how fast I drive, or about 12mpg towing a car. I have enough power that I seldom notice the car. Just on hills.

If you have an Onan Genset you can convert it over to propane. That is what mine is and it works fine. Just run it off the propane tank then.

I am considering a new cruise control as mine has failed. I am saving the money for a "King Cruise" system. Bout a thousand dollars. Most of the add-ons are for gas engines. Very few for diesels. I have tried to replace the original "Dana" unit, but they have sold out and don't stock the old units anymore.

I use the "Boost" and "pyrometer" guages all the time. If you hold the Pyrometer temps too high for prolanged periods, you can really build up a lot of heat in the engine. Can't tell you if the Cummins will do the same. I do not have a Transmission Temp or Fuel Pressure guage, but they would probably be handy.

Pyro

Hi, GW, Cooperhawk, and fellow diesel fanatics! I have a 12V in my 36' Classic D/P. After I put a fuel plate in the pump, I had to adjust the star wheel for less fuel because of high pyro readings and billowing black smoke on accelleration. It doesn't smoke as bad now, and the pyro never gets much over 1200. In fact, on our trip thru the White Mountains in Arizona, at an elevation of 9300 feet msl I could get 26psi boost and stay under 1200 on the pyro. With what I now know, the fuel plate was probably a waste of money. Last year, driving along Lake Roosevelt, where it was 114 degrees, I saw the coolant hot light for the first time.
So, besides an interior remodel, the 2 mechanical projects I can sneak in, under my wife's radar, are a radiator mister and an engine oil cooler. All in all, I like the 12 valve just fine.
My mileage runs right at 10mpg towing a 4000lb jeep and 12, empty. Regards, have fun. Diesel Phil and Sam

Scott,
I took your advise and got rid of the condensor. I didn't think there was such an issue with the pressure and all that. But I did some research and you're definitely right. My setup was too restrictive. I just ordered a tranny cooler (plate style) rated for 28k lbs. Its 11"x11". I also just ordered 2 16" electric fans that push over 3000CFM each. That mechanical fan was too far away and the shroud was not even close to lining up. Not even the right size.

Paul Whittle
Paul,

What springs do I have now? Are these 5400-5900 what I need? I am definitely interested. How easy are they to swap out? Jack it up and compress the springs and getem outta there?

Greg

Okay, I'll admit to ignorence. What is the 12v. Cummins?

I have a hayward electric fan mounted on my rediator, but my fan clutch is now siezed. Gotta get that fixed before Spriing. I think I can get it out without a major tear down. Knuckle scraper though.

Did you know that when the fan siezes up and runs all the time, it can actually run hotter! Isuzu mechanic told me that. Saw the "HOT" light first time last summer.

12 V cummins

Good morning! I meant to say 12 VALVE. as opposed to the later 24 valve.I googled King Cruise last night, didn't know there was such a thing, and now, I believe I need one of those, too! Would like to have a big electric fan but I talked to Flex-a-Lite and Haydan...they don't make one big enough. Maybe my next year project might be an aluminum radiator and a BIG electric fan. ???????????...GW, where did you get the big altenator you are using??? Furniture arrived yesterday, from the factory....if I don't get busy my wife won't type these notes for me! Have fun. Regards, Diesel Phil and Sam

Cooperhawk - one thing I've learned when working in close quarters with the radiator is to cut a big piece of cardboard and put it over the face of the rad. It's thin enough that it should not cause much for clearance issues, saves your hands from scraping on the radiator, and saves the radiator from little dings.

Man, that's really good advice and I will surely do just that. This isn't foing to be fun as I have to do most of the work laying on top of the engine and reaching down. Need a big piece of foam to lay on top of the engine.

I just had to replace mine on the way to florida last month. You can take the four nuts loose that hold the fan to the clutch, then the four that hold the clutch to the water pump. Pull the clutch up and out, leaving the fan in it's little area. Just install the new clutch in reverse order. I did mine in 21 minutes on a hot engine. No big deal.
