Keith Very interesting, I should've of thought to look at that. But then again I should do a lot of things that I don't. Glad you noticed this, it's very interesting that they went to all the trouble to change the half dogs to the newer style symmetrical dogs. Ron Sent from my SM-G900V using Tapatalk

The first turbos we had were in those 3 H-613's we had, they had the water cooled schwitzers.Ron Sent from my SM-G900V using Tapatalk

Glenn, do you remember the early blocks with four bolt mains at 4 and 7? Ron Sent from my SM-G900V using Tapatalk

The ENDT'S turbo engines came both ways 18 and 20 stud heads. The first blocks had 18 stud heads with 9/16" studs. Next blocks came with 18 stud heads but the two corner studs were 3/4". Last blocks had 20 stud heads (double corner studs) 5/8" studs. There were even special washers made that looked like an inverted top hat so if you had to replace a head on an older 18 stud motor you could use a later 18 stud head with the 3/4" holes in it.

We had a Gramm horse trailer, #T-106. Was a drop frame trailer with frame rails that were actually formed with a radius for the drop, not squared and fabricated. It had truss rods built under the frame like old railroad cars. I think it was a 1950. My earliest memories of it was it being a 40' nine horse trailer, single axle spring suspension with 22" wheels. Sometime in the early 80's ( pretty sure) it was taken to Morgan trailer to be lengthened to 45' to make it into a twelve horse trailer. Morgan lengthened it and installed Neway air ride suspension with Standard Forge axles and 15" wheels. We did the work of finishing the inside in our own shop. When Morgan lengthened it they rebuilt the rear bumper and sill and threw the piece that had the GRAMM drilled in it into the scrap pile. Needless to say(as sentimental as we were) that didn't work! They were told to put that back on the trailer which they did! Trailer went to Cohen's scrap yard in Thorndale, Pa in the late 90's-early 2000's. Cohen's actually sold it to somebody, I think from Ohio, who was going to restore it and use it for show horses. I sure hope it still says GRAMM on the back of it drilled out in big letters!

I don't think I actually have a dream truck per say, but if I was physically able and had the money I would love to have a certain H-61 Mack that's in southeastern PA Ron Sent from my SM-G900V using Tapatalk

It's a little more involved than that,It takes a special filter head and you need a way to drain the oil back to the block or oil pan. Ron Sent from my SM-G900V using Tapatalk
