Trying to start a CAT D343/1693 that hasn't run in nearly 30 years!

The dude is full of knowledge... hopefully his workers are absorbing as much of his wisdom as possible!

This is one of the all-time great engines from any manufacturer. I've never been around the 1693 version, but have heard nothing but good about them from anyone who has been. Down here in Southeast AK, there were a lot of 343s in cannery tenders and medium size tugs, even in a few seine boats. Sadly, there are getting to be less and less of them. We have one tender in my town that has one still in service, and I can hear it from my shop when it comes into the harbor and maneuvers to get into it's stall. I love that sound, it is like no other. It seems like only yesterday that we were hearing the Atlas and Washington heavy duties in the boats and now they are gone. It wil be a sad day when the last 343 is gone as well! Incidentally, I greatly enjoy your channel, you are carrying on with the great Alaskan can-do tradition. I don't doubt that like all the rest of us, you have something stored under a blue tarp!

I ran that motor in my Dad's 1982 Peterbilt twin stick. It would walk up hill like nothing else I'd ever drove. Granted it drank fuel but it pulled better than Dad's other truck with a V8 Cat. 1693 also ran cooler than the V8 Cat. Boy That Was The Days "Getter Done" and Talk About It Later 😂

Unplug the glow plugs if you can hear me😊

Back in the day when they put them in trucks that was big power. I knew a guy in the mining business who had a DM800 Mack with the early Mack V8. After it blew up a couple of times he repowered it with a D343 I think he did it around 1970. As far as I know that truck is still running today. It had a total frame off restoration like 10 or 15 years ago

I've rebuilt many 343's. Those babies are bulletproof and still used in many applications today especially marine .

They were great engines! I rebuilt many at Ohio Machinery!

That's a thrill I never get enough is getting a long dormant motor fired up again.

A quick and dirty way to see if the rad is being pressurized, is to put a nitrile/nylon glove over the rad cap hole. If it puffs up or blows off, you know something is wrong.

Glad I found those channel. I’m sitting here in Wasilla and remembering my dad’s passion for repairing heavy equipment. There’s still a few of us Bywater’s floating around up that way.

Love this kind of stuff. By the temps looks like all cylinders are doing the job.! Thanks for the video.

It run better if you unhook the glow plugs

Love the sound of pre cup diesels.....eat your heart out Greta. New fuel filters and feed it plenty of ATF and it might wake up some.

Be interesting to see one of them with air to air in a truck !! I used to drive them years ago but with the new technology would be a power change either way air to air and few other mods..

My buddy has one in a long nose mack glider. Overhead cam, neat engine

That is music to my ears I worked at a Cat Truck Engine shop in the 80s

Need to get myself one of these for the garden. All the best to you.

Don't worry about the oil pressure the rack won't open till it gets at least 5 psi

Couple ounces of two stroke oil or marvels mystery oil in the fuel might clean up the injectors

Did you take the lead off the glow plugs ?
