I have an E6-350 from an 82 "Cruiseliner" and it had a chassis mount charge air cooler. This is slated for my 58 B-61 and runs well. Had an 81 R model that was a 350hp ETAZ-673 something with the water cooled tip turbin setup. I still have the engine but it was knocking in the lower end. I'll have to look at the block for the full set of numbers.

Forgot youz guys like photos so here are a few from long ago of my 58 B-61. It still resides in the back of the shop. The photos are quite old but still have it.

Thanks for the update on the model number. Have you thought about oil filter to steering box clearance. Possibly go back to 2 filters? By the way what's the serial number, Dad's '57  B-61T-15659,  is yours close.

I have a 57 also. I'll dig out the titles and post the numbers.

The 1958 is B61ST17759, and the 1957 is B61T12146. I'm probably going to go to a two filter setup but utilize a later model hydraulic steering gear setup. I have several slip and splines from other trucks so will fabricate a steering shaft to the gear. Neither truck currently has power steering and are all original. I've built a "chin mount" charge air cooler to breath through the front bumper for the E6-350 to be installed into the 58, and have a 300+ with engine mounted charge air cooler, (tip turbin) going into the 57 truck. Both trucks will be modern in driveline to keep up with today's traffic.

Little of the work so far on the 57:

Not much of a "Dupont Overhaul" type guy myself, everything under that truck is either freshly rebuilt properly, or new. Still need to plumb for air but the truck drives with front brakes only.....

3.70 gears and a current double over tri-plex on tall rubber would get it down the road pretty good but this truck is to replace the trusty, yet crusty old Dodge one ton so will be swapped to a single stick 10, or 13 speed trans.

This is an ETAZ673A, (300+) in my white R model. This engine is slated for the 57 B-61 I posted photos of. The old R model is a good truck but many of it's parts are going to be used for donorship into others. The engine is spoken for as are the 3.87 Mack rears which will probably wind up in my 62 B-67ST.IMG_0179.thumb.JPG.fdd67e9aa904126ba7bbc40b1ad0c6be.JPGPIFF.jpg.d5fcdb163251792b3dc7bee7b2a38304.jpgIMG_0178.thumb.JPG.9b1d40498eeccf8de5f1ed67d13e5aee.JPG

Were all tip turbine's two valve? I've seen that set-up in hard nosed Macks into the late 80's... but the two valve was discontinued with the e6 or was it?

I don't know for sure. The four valve E6 engines were coming out in the early 1980's but I've not seen a tip turbin setup myself past early 1982 as the move to chassis mount charge air coolers was going forward.

The two valve continued to be used in DM's into the late 80's with the tip turbine because the steel hard nose wasn't able to accommodate the chassis mounted air cooler (CMCAC).  In 1988, the DM-690 was fitted with the CMCAC.

I like your philosophy on the Dupont overhauls. What was welded to the back of the cab?

The cab was cut out rectangular for a crawl through many years ago. I welded in a new back panel to return to the original style rear window. This truck is to be my "everyday" driver. The current one ton Dodge is falling apart from rust.

A few from back when my brains worked for this kind of crap:

DM series were never popular around here except with garbage packers  and mixer trucks. Dump trucks for some reason were either R models, or RD models but this was into the early 80's best I remember when I left spinning wrenches and busting knuckles full time.

from what I recall yes. The most common were in 285 and 315hp. however there were some very early 300 and 350 ratings with the water and air side mount cooler. I have yet to see one of these but many discussions on them coming out just before the front mount intercooling

Has the look of a DM.  Big frame and a DM style fuel tank.

Can you get the engine number?

Its not local, can you tell me where to have the seller look?.... and, what's that rig worth?... as pictured The 6 speed is already sold.

 

I always forget which pump went with which engine.. the Maxidyne's had one and the 300+, 350's had another....

If the sheet metal data tag is missing from the pass. side of the block, the engine code is stamped into the top of the timing gear case in front of the injection pump.

It's worth?  Depends.  Does it run?  How well was it wrapped up?  Did water get in and freeze?  Why was it taken out of service?  How many hours?  

It is 2,000 lbs.  What is the price of scrap?

I was under the asumption that all 300+ were of air and water charge cooled. I see yours is just air to air

I think the air/water setup came out in 1981 or 1982. This R model is a 1980 and the engine is original to the chassis.
