That lifting ring that you guys use you guys make that or did you get it somewhere

[@JG-iq2qv]

The valve spring collapse has happed to me on overheated zero turn mowers. Mainly on the exhaust. Keep in mind, these 1500-2000 hour failures on commercial mowers

[@richb4099]

We called real loose valves/guides like that, 4 speed guides. You could shift them, 1-2-3-4 😂

[@codegame027]

I suspect the quality and precision of your work on an engine like this is substantially higher than is typically seen or expected on these engines.

[@neithertwosturrr3016]

Most of these engines were meant to be maintained and worked on in the field. The reason this thing is probably so beat up is because there was bandaid after bandaid and not only that but alot of the build up from contaminants actually helps seal alot of the surfaces..... until it doesn't anymore than you get what you get in this video.

[@dontblameme6328]

Seeious craftsmanship here.

[@camz8755]

Jim could someone grind off the mushroom on your valve seat insert tool. It makes me cringe with every blow of the hammer.

[@darylhudson777]

Comparing piston bores to that engine used in the oilfields...the Cummins X15 piston is only 5.39 inch diameter

[@popswrench2]

tore one down , natural gas pump station ... they are slow , long life and KooooooooooooL.... work GREAT if safety shut offs are in place too 😊😅

[@Rich-o7n]

If I remember jim commented that the collapsed spring was in backwards and the collapsed part was on top. I'll bet everyone's right about exhaust gas leaking up and If I remember correctly the valve guide came up out of the head and directed the games and only warmed the top coils of the spring and that's why they collapsed. Weird stuff man

[@MikeHarris1984]

I imagine the exaughst spring collapsed from no maintenance and exaghs gas leaking Glad to see premier back on sunday morings!!!

[@Aleks_Mechanics]

Notification squad Have a Great weekend!🔥🔥🔥

[@BookkeepersHusband]

This thing was rode hard and put up wet! Never seen a valve seat area beat up so bad! 😅

[@BobSmith-mj7ik]

This the most unusual engine I have ever seen

[@scotthultin7769]

29 👍's up Jim's thank you for sharing 🤗

[@TimBinns68]

Get on and see if you can step up the hp, lol

[@chadstewart8567]

Finally. I caught a live on time.

[@CarlBright]

Love vids on old engines!!!

[@IrenESorius]

👍‍‍🌟🌟👍‍‍

[@Sunspot-19]

Just look at that Pennzoil residue!! They were too cheap and lazy to change the bloody oil!! I remember running some 12" diameter pistons through the bandsaw so they could be dropped into a crucible in my foundry. Nick, my black cat requires leaded premium cat fuel! You oughtta hear his purr!! 😎 Hasta be a Chrysler, you had to machine everything!!

[@JAMSIONLINE]

Keep in mind, this engine runs on the raw natural gas coming out of the earth 24/7. No fancy fuel additives here to keep your valves clean.

[@Sunspot-19]

@@JAMSIONLINE I couldn't help but to go there! Next oil change, Valvoline Restore and Protect!!

[@zMeul]

please show it running and if there's a before and after that'be golden

[@Hopalong..75]

I believe that valves that operate by vacuum instead of being cam driven are known as Atmospheric

[@wackowacko8931]

Those engine were everywhere out on the prairie in NE Colorado in the 70s. Everyone was pumping oil out of the ground back then, and you could hear them running many miles away when it got quiet in the evening. They are all gone now, the only pumpjacks that are still running use electricity exclusively, because you don't have to maintain them and they are quiet. Running these engines off of NG was cheap, but it was horrible quality. The NG you get in town is worlds away from NG straight out of the ground, the stuff out of the ground is incredibly dirty. I worked at a NG processing facility in the 80s, there were still some pumpjacks and a couple of hit and miss engines still running then.

[@geoffkeahey2651]

Early 80s, I worked as a pumper on a bunch of these. The engines got very little maintenance. The most I ever did was top off the oil and antifreeze. They ran with pretty much little to no problems.That spark plug is not typical, It appears to have been hit, and is not the usual. Very simple and have no water pump to the radiator. I have been told that the old shrimp boats used the same engines.

[@celtics9348]

That is high level craft on a junk head. I bet when it was new it wasn't close to that precision. Both you guys are awesome, this is what skill and integrity looks like.

[@jimmotormedic]

Absolutely enjoy these videos. Being a mechanic that works on a lot of stuff no one likes to do any more I can appreciate your skills. I've always wanted to get into machine work and learn more about it but never had an opportunity. No real good options for machine work in my area anymore. Keep em running, great stuff!

[@popswrench2]

seated perfect , but to have slightly low , after 10K hrs , valve will pound its seat up and out naturally 😊

[@taylorh3930]

In western canada most pump jacks have low compression chevy small blocks running them

[@lyman1965]

57:28 not quite a small block Chevy and yet I think the specs you posted on screen said 327 cubes so they just got there a different way . For shits and giggles how many hp would a small block make burning NG at 600 rpm I got to believe more then 15 but maybe not.

[@johnalexander4356]

We ran those on my grandpa's ranch. Also ran on the pump gas. It was the most reliable engine I ever saw. We checked it daily and did an annual rebuild, which was usually just an internal inspection and valve job. We also used the pump gas to run a Chrysler 413 ci irrigation pump engine. Both of those engines were really clean when we opened them up. I'm guessing that engine was burning as much oil as natural gas!

[@taylorurban2566]

I am by no means a machinist but, didn't you guys spend hiw many thousands of dollars on a big ass lathe? Why not just machine your own parts?

[@stephenbridges2791]

I think you got the guy a pretty effective repair. Good for several thousand hours, would be my guess.

[@MichaelHeinrich1]

I love the amount of diligance you put in your work no matter how old or low powered the engine is. I have only one question: why don't you use liquid nitrogen to install the guides and seats?

[@burdickjp]

What's the little USB-powered light you're using?

[@darylhudson777]

Those oil pumping units we're referred to and maybe still referred to as grasshoppers because they look like the back legs of one

[@popswrench2]

wood you mind giving a $$ value of your charged labor for this ???

[@powellmachineinc3179]

The problem with knurling is you loose heat transfer and that accelerates guide wear.

[@The-6666]

Would love to see you resurface Cylinders that has a 33” bore and a 51” stroke

[@jcnpresser]

I thought propane and cng engine ran slot cleaner than that. I guess when one chews on that much oil like it’s probably been doing, then yeah, it’s going to get carbon up.

[@chrissutton3043]

Do they use any kind of throttling valve? Or is the intake path just wide open connected to the top of the well?

[@richardcranium5839]

thats a little one. ajax made comperssors with an engine on one end and compressor on the other up to 24 inch driven by the same crank.

[@danielpintos1443]

Hola! Aquí en Argentina el uso de gas natural en motores está muy extendido, cuando hay que cambiar guías de válvulas se optan las que son de bronce, dan un mejor resultado. Saludos!

[@markchodroff250]

Fantastic job ! Always a great video!

[@beachboardfan9544]

28:23 Could you guys show more about how those tools are setup?

[@brucepeters508]

no joke is there sugar in the ketchup !

[@scottharvey7730]

Is that a Crack off of the spark plug hole? Or a rough spot in the corner?

[@BerryMcCaulkiner859]

Does the video look dark or is it just me?

[@Richard-be9gp]

Liking the current variety.

[@richardcranium5839]

thats a self centering seat lol

[@johnd21]

Great job guys

[@meagain6889]

Great Job!

Chuck Norris and his wife Gena have now come out with a healthy dog food. They are definitely dog lovers they have golden labs from what I remember. He lives at Lone Wolf Ranch in Texas.

[@Alias_Jack-Alias_Jackie]

Engines like that on unmanned stations will have an external oil reservoir (day tank) with an automatic fill valve that maintains a constant level in the sump, often made by Murphy. The external tank is as big as you want it, but 20 to 50 gallons aren't uncommon. The valves have contacts on them to shut the engine down if the level drops too low.
