The next pieces needed to mount the grenade to the shift handle is the thread adapter and a jamb nut. I had the adapter machined from brass with 1-14 external threads and 5/8-11 internal threads and about an 1/8" shoulder. The jamb nut started life as a typical hex flange nut and then I had...

I found some more info from the Jacob's literature-not Cummins- and it warns of no 25B with divided entry turbo and also when I load the CPL 0026 the application guide points to model 425A which has no warning about turbo entries which makes me think the 425A is more versatile. So would a...

With all the holes drilled, tapped, and a few coats of OD green applied it's now time for painting the description onto the outside. Initially I wanted to replicate the original script that would have read "GRENADE, HAND FRAG, DELAY M26, 5-69 COMP B LOT LS-3" But since this isn't truly a...

First trial fit of the switch in the grenade with the fuse and spoon installed. I used a dremel to carve out a relief in the grenade and I chamfered the corner of the switch but I think one could get away with only doing one of these steps. The switch protrudes right at the center rib and...

The grenade had a 1/2" hole in it top and bottom with the top hole already threaded for the dummy fuse to screw in. Luckily the bottom hole was well centered so to have the best chance at fitting the switch inside I drilled and tapped to the largest size I could while leaving a slight shoulder...

To start with I got a 3-pack of inert grenades to fondle and find out which one felt the best in hand and had enough room for a micro switch. The pineapple grenade was the smallest one and the baseball grenade was a little too bulbous for me but the M26 lemon grenade was just right. Here is...

I just completed my most recent project which was to put a grenade shift knob on the shifter but with a twist. In preparation for jake brakes I wanted to be able to switch the brakes on and off from the shifter like modern big rigs so I went down a rabbit hole to put a micro switch inside the...

Thank you, it took a lot of work to get this finished but it turned out better than I expected. When you pull the pin there is a few seconds delay before...

I finally got my functional jake brake grenade shift knob installed! Just squeeze the spoon and the jakes come on (once I get the jakes installed). I will do a write-up on it in the hot rod section later but I couldn't resist not putting up a sneak peek...

Ok, so here's another question. Can jake brakes with the auto lash adjusters be used on an NA engine safely? I will most likely have the jake heads installed a year before I get the turbo put on.

77 AMG, how is your crew cab conversion going?

Do you guys think that a divided exit manifold combined with a divided entry turbo would not require the special adjusting screws?

I found some info on the PACBRAKE website regarding the single vs divided entry turbos and they call out special adjusting screws for divided entry turbo applications. I don't know anything about PACBRAKE but they use Jacobs same nomenclature on things. Maybe some of there parts are...

I am going to make a new batch of 5 ton hub helpers and a prototype 2-piece 2.5 ton hub helper. Before the laser cuts these out does anybody want a 5 ton version? Please PM me if you do. *Once I have a chance to fit the 2.5 ton version up to an M35 and I'm happy with it I will offer them for...

Could a front camera record your trips like a dashcam or is it live footage only?

I really like that rear view camera setup. Can it switch between GPS and camera modes?

Would transport company soldiers ever carry carbines like a CAR-15 or XM-177? I thinking of tankers & artillery personnel who would often carry shorter guns due to space constraints...

Came across this outfit on Ebay this time and look what the fine print says now:

I enjoyed watching the youtube portion - your truck looks great! You don't often see people standing next to these and that video showed just how big and tall these 5 tons actually are. Some of that gets lost in pics / videos of trucks by themselves.

Those complete dipsticks are cheaper than I expected. Cleaning the draft tube is free so I'll try that first.
