This is the amazing power plant, an STS .21. It is affordable
and makes crazy power. Ryan has the STS .28 he is testing, and
says it is also showing signs of awesome power.
The mesh is important, to tight it destroys the CB. To loose it
destroys the spur. It has to be PERFECT, just a tad of play, not
stuck tight, but the teeth meshing fully.
I use the MGT tank, it is the legal limit in size, and uses EVERY
drop of fuel, and will run when the truck is upside down. This
is also amazing, this project was MEANT to be. Ryan had the stock
Mammoth tank installed, and then he drilled for the pipe hangar.
Those two holes lined up for the front two legs of the MGT tank.
Wow... what are the odds of that? I start each day with God and
He rocks my every day, every day...
The MGT tank mounts to the chassis directly, so to prevent foaming
I used rubber under the legs.
Like so, just a bit of cushion to help it not foam up the fuel.
See the bottom middle of the tank has a sump the pickup sits in
slurping up every drop of fuel.
The view of the tank from the top. I moved it toward the middle
just a bit for better CG.
Ok, it is time for Mammoth Diffs 101 class. Here
is a link to the Shimms. I have not blown a diff since the
center diff, but they still need to be fixed, with longer screws,
you can find that info on the "normal" mammoth page
here on my site, and they need to be shimmed. Then they are DONE
forever.
Here is the diff pinion with 3 thin shims, or one think one thin.
See them there between the gear head and the bearing. It pushes
it out to mesh more securely with the ring gear.
