Never ran a V12 Hayseed, but spent lots of time in unmuffled Detroit's too.

I used to bring 12V-71, and 8V-92 engines to the point of falling off in power with portable load banks and like that truck in the video, they open right up to the task. One of these days I'll get mine installed into something. Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

tenfive0 Posted March 13, 2020 Share Posted March 13, 2020 Need lots of tool boxes or another support truck to follow you to carry all the binders and chains to tie everything down on three trialers. Quote Link to comment Share on other sites More sharing options...

He decided to open it up and refresh it. All 8 pistons had broken rings!!! And it still pulled like crazy and showed no signs of being hurt, LOL Quote Link to comment Share on other sites More sharing options...
Freightrain Posted March 13, 2020 Share Posted March 13, 2020 There was a V8 mack video from down under with a guy in a KW just awestruck about this mack running away from him up a grade. I was just searching for it the other day and couldn't find it. Quote Larry 1959 B61 Liv'n Large......................

I've worked on dozens of generator sets and there is no finer engine in that duty to produce clean power than a two stroke Detroit Diesel. This is given the power pulses imparted to the crankshaft which in turn drives the rotating field, etc..... Those old Detroit's were built much like a Model T automobile with the most simple of technology and most anyone could keep them going. Unless they physically came apart, they tended to run and run just like the Energizer bunny. Just wear ear plugs and keep oil in them.

Just wear ear plugs and keep oil in them. when they come apart;; boy do they. working at mack in CT yrs ago there was a cabover with 318. truck sat for week or so. guy comes to pick it up. hits the key engine goes from zero to beyond wide open in seconds. as most cases the emergency stop cable froze.. my job to smash rear cab screen and climb on top of screaming engine ;; manually flip shutoff. too late engine trash. baskin robbins in ct had fleet of 318's and 350 DD 's. baskins had a mechanic ,jimmy Cassidy he is one of the best for setting up a DD. the stack tips were blue on one ole binder with 318.. LOL . Texaco had long nose GMC 's with 318. clear night you could hear them climb rte 34 . knew when shift was coming listening to engine. like real muscle cars of days gone by.. big truck engines had a sound of their own. maybe imitated today -NEVER duplicated 1 Quote Link to comment Share on other sites More sharing options...

I ran a 1988 R Model. The motor had to be replaced due to a previous drivers neglect. The motor we got for it, we were told by Mack was the very last E6 350 to come off the line as they switched to the E7. I know where the truck is still sitting but it is completely rotten now and someone after me over heated that E6 and cooked it. The truck currently has a 237 they stuck in it.

We met him that evening at a roadside stop where we all camped in swags! I had never driven a V12 coupled with a 13spd. Paddy said just hammer down and so I did. I was so excited that I left my son standing alongside the road. You can see him to the right. He caught a ride with another truck!! An interesting fact is that the Ford on the trailer was bought new in Medford, OR as a slab cab for a local logging outfit. It had a V903T in it that I wanted. So I kept the motor and Paddy wanted the cab. He built the sleeper on to it with another truck he had. 1 Quote Link to comment Share on other sites More sharing options...
Bullheaded Posted April 1, 2020 Share Posted April 1, 2020 Cool story mackdaddy. There were a few Freightliner cabovers in my town with V12's but I never got to drive any. Lumber haulers here had some big fancy iron back in the day. Ford CLT's with KT600's, lots if Mack V8's, Freightliners with KT's and V12's, Pete's with 3408's. 1 Quote Link to comment Share on other sites More sharing options...
