What have you done to your CUCV today/lately - Part 2

[The FLU farm]

Those trailers are HEAVY.
They make a modern day dually truck squat a lot.

It does indeed affect the suspension on my Ram 3500 DRW quite a bit.

But it's not so much that the trailer is heavy (just over 10,000 lbs. as I recall) as that the rear 20 feet are empty space. Most of the weight is in the living quarters up front.

With the axles centered under the garage, that puts a lot of weight on the coupler. On the other hand, it doesn't matter if the garage is empty or if there's a 5,000-lb. vehicle back there.

Are those 285-75-R16's?

Not quite. They're 255/85R16 M55s.

A few small bugs to work out yet, but have fire under the hood again after a 19 year powerplant void sitting in storage. Feels like it just wants to go when the shifter is dropped.

Vortec 5.7 with a carb I assume..

I went with the factory EFI and the GMPP 395 hydraulic roller cam. Even with a dead cylinder(more on that later) and the ecu overcompensating the air/fuel mixture it'll still move my M1008 with ease

I run that size on my 86' M1008 and 79' k20..... I luv em

I do have to give those Toyo M55s some extra credit.

They've been on there for about 20 years and still look like they could be a year old, despite our brutal UV. And the thread is in great shape, except for where the tire chains have left some marks. Needless to say, it doesn't get driven on public roads all that often, or fast in general.

Heck, it's been at least 10 years since I added any air or checked the pressure in them.

Nice!
Mine is actually a 300hp Mercruiser I built a couple years ago for the ocean boat. Was just sitting on a stand. It has their Thunderbolt 5 ignition system with full knock control. Will just be for break in and to get the truck inspected and registered. Should give me a good idea of what I will want to build for the truck down the road. Hoping the .020 over 5.7 is plenty but may look to stroke the next one if it lacks pulling power on our hills with an 8000 lb boat behind it.
The marine carb does not have a bump up while in choke mode. Hopefully will have the whole package replaced before next winter. EFI may be included then but hoping to avoid electronics with this truck.

I run the M55's on my '08 2500. They are the (33") 285/75/16's and are snug. Awesome tires. Same bolt pattern as on the '86. Will use them for clearance checks on the M1008. Would like to be able to go to a 35" to help with rpm's at highway speeds. Should give me a good idea of what I may need for a minimal lift. Not a chance I am going to chop the fenders on this beauty.

No need to cut the fenders. Even thin tire chains will create the necessary clearance withing a day or two.

i just replaced the transmission, made up the three torsion rods, from scratch! as i ripped the bell housing off the old one
made fresh brake lines for the rear disc conversion , from the frame line back, including gravel guards.
putting stock exhaust back in after having 3" pipes rattling everything to death.
Led lightbulbs all the way around ,, including the led flasher .
new tailgate strikers, trunions and arms? (folding support)
new tires /wheels bulge lugnuts , no more acorns

I a set of BFG KM2 and Toyo MT 255 85r16 on my trucks. Both sets were purchased a few months apart in 2018. Both brands have been great, but I can tell the Toyos are holding up just fine. The BFG KM2 will probably have to be replaced this year...

Spring break is here, getting some time in the shop. Over the last month I managed to reseal the transfer case. In the last two days I removed the transmission and pressure washed it. Getting ready to reseal it this week. Then it will be time to pull the engine.

 

[BIGHOSS]

this week was a rear main seal , oil pump pickup tube , new oil pan/pangasket,,,,
rebuilt the rear spring stack ,centerpin 4degree shim , urethane bushings /greasable bolts

on deck : complete exhaust manifold back and re string the seat spring under the cushion -- i came up with an idea to use aircraft cable and make a mesh --- as the seat spring grid is big$$$$$$$$

Realized it’s finally time to take off injection pump for a rebuild.
I’ve had my M1008A1 almost 9 years and haven’t a clue if pumps ever been off and rebuilt before I bought it.
It’s time

Losing power on hills no matter the speed.
Making more noise when increasing throttle with noticeable power loss at same time plus it makes blue smoke when it happens. (I do use a lot of two-cycle oil in fuel, hence the blue smoke).
No black smoke.
Air and fuel filter new.

Starts and runs fine, until you need decent power.
Keeping this pump with truck, so it will be a bit without truck.

Not looking forward to this………

There pumps fail primarily in two ways. They leak fuel at the throttle shaft or they won't start when pump is hot. Losing power is a fuel starvation issue. How is your fuel filter?

Fuel filter is new.
Wix brand and the original setup.

Noticeable power loss and the sound it makes when doing it almost sounds like Pre-detonation on a gas engine.
I use Seafoam and two-cycle oil consistently.

Pump looks original but I really haven’t a clue if it is or not.
Truck has over 100k on it now so I’m not surprised it’s slowing fading. Won’t last forever.
Will wait for cooler weather to take it off and send it in for overhaul.

I only drive the truck 3-5k miles a year so it’s not a priority

Retard it a bit?

 

[Tinstar]

Retard it a bit?

Possibly

Will read up on that to make sure I’m not chasing my tail with it.

Try adding some Power Service in the gray bottle. Don't be afraid to pour it in on the heavy side of recommended rate. Easy to see if it helps!

I will do this later today.
I use seafoam but will try this

Thanks!!

When first getting the FLU HME it was smoking badly. Did a fair amount of research and settled on Liqui Moly .

Not that I can say what actually fixed the problem, but it went away.
