Increasing the power of the Detroit Diesel 6-71

[luvrbus]

I think your problem is the engine is not getting full throttle they will reach full rpm and still not be getting full rack and your first Detroit is going to take a few driving lessons for you to get the hang of it IMO

good luck

Thanks Luvrbus.  I have this feeling that once it's gone through and a few gremlins are caught, that I'm going to love this motor.

All the whining is just me being social

Hate to cross post, but in parallel to figuring out the motor, I'm also having to work on the other aspects of making this a conversion.

I just started a thread in the "projects" forum if you guys want to see what this motor will be pulling around.

Thanks Everyone!

Donald, I thought those were built by the Crane Carrier Co in Tulsa OK

Do not think I ever saw a CCC that could be under 50,000 or 25,000lb cab & chassis, always under some real heavy trucks, like the FWD & Oshkosh.

maybe but I was thinking that Hendrickson provide the chassis which I thought was affiliated with Oshkosh...maybe not in 1983
he says it's a Hendrickson/Calumet....I am guessing it has walking beam suspension...whoever made it .. it looks Oshkoshy to me.. complicated by engineers...
These kinds of rigs never get built by users or drivers...they always send the freaking book keeper... and the guy inside doing the medical stuff probably follows along in a limo...

from google:
In 2001, AK Associates acquisitioned one of its competitors Calumet Coach Company to forming Oshkosh Specialty Vehicles, the largest mobile medical manufacturer in the world.....Calumet City, IL.


from Hendrickson...
Other truck manufacturers come to Hendrickson for truck sub-assemblies, or even the entire vehicle with the customer's own label. The new Ryder truck is one of these. The Manitowoc crane carrier is another. The Cline Truck Company of Kansas City, Missouri, bought some of Hendrickson's sheet metal for its trucks. Hendrickson also built chassis for International fire engines.all custom-engineered and hand-built. Lifetime production of Hendrickson (trademarked) trucks is estimated at 5500 units.


But I have been known to not know the whole story...

I saw some crazy stuff coming out of CCC in Tulsa in 30 years like the Mack garbage trucks with the Scania engine and the Dinia funny looking oil field cab over truck and some I never heard of going to Turkey and the mid east

This is a shot of the suspension...as well as I can get my phone to take it....

[eagle19952]

you know what, you might post pictures of your dash controls...looks like some kind of axle inter lock....need more info. you might be driving 2 axles in places you only need one...

I forgot about the hydraulic leveling jacks those had I see one in the photo

That's Neway air suspension. Usually rated at 46,000lbs for the tandem. Great suspension in that it has an upper trailing link that prevents torque up of the axle. The only draw back is the arms are low to the ground and getting hung up on a curb is not out of the question.

Your idea of making a stand up engine maybe the best. There was a mid engined motorhome chassis for using on garage motorhomes. It used a Cummins ISL at 450hp and 1250lb/ft torque. And actually, it didn't stick into the cab. The interior reminded me of a boat since there was a hatch in the floor for top of engine access. Good Luck,TomC

Yes... does have.  The switch seems to work (Light when you turn it on... PShhhhh...when you turn it off).   I keep it off course, but if it were possible that it weren't releasing... that's one to keep in mind.

That's good to know TomC.  It does hang low, but then again, so does the motor.  Probably take out the oil pan first.

well that is being used properly:

I meant to say "I keep it off of course".   

Taking "of" out gives a whole new meaning
