One ring vs two

[czar800]

I never seen it, but my dad always said they would run backwards.

Feed mill I worked at one summer in college had a crackerbox Dodge with a 318 and a 13 speed. I avoided that *b-word like the plague.

My dad bought a septic tank/ redi mix plant when I was 15. Had an early 70's ford f600? I believe. Tandem boom truck with a 330 ci gas. 5 and 3 twin stick. Needed all 15

I've cn it, I've also cn a 6 cylinder caterpillar run backwords

That had to be ugly!

From two rings, to one, then to diesel engines, and now to cement.

This is a great thread.

Pull starting a old road grader and had it in reverse instead of a forward gear. Airfilter was on fire nicely

Trying to cover it all.

Any other damage?

Nope just needed a new airfilter.

Powered a 671 out on a hill and when I clutched it she lit backwards. Oil bath filter on the side of the truck made a huge mess. Man I love old worn out junk.

Poor people have poor ways.

There's a timber jack screaming on every hillside here fortunately ares has a 5.9 cummins.

The best thing about my all my worn out junk is that it's mine!

frick sawmill powered by a 2 stroke bessemer diesel what a lovely sound.

Just about any diesel with mechanical fuel injection can run backwards. It won't run well. Injection timing is retarded. If it runs long enough, the lower end will fail. The oil is pumping oil the wrong way.

We have a few Oliver 1950 tractors they came with a 4 cylinder Detroit diesel, aka:Jimmy, I've got mad respect for anyone who can work with one of those all day with an open station and the exhaust pipe right in front of you. Dang things sounds like it's gonna spin out of control, hard to believe that they turn so low of rpm.

Yeah, two-stokes will run backward, old news. The bloke next door has collection of old tractors that have some that will reverse by using the injection system. Now about using one or two rings, what about three rings in a two-stroke.

I raced a Kawasaki 350 Bighorn rotary valve engine in my desert racer - it had three rings to dissipate heat from the piston. The first race I ran it in, I was running second in a field of about 300 racers when I reached the first check. As I came out of the check the engine seized. I don't know, probably some sort of heat build up without the air flow. Anyway, I got the engine running again and made my way back to the pits. When I tore down the engine the third ring was still free and that's what allowed me to get back to the pits.

I rebuilt the engine to different specs that allowed it to run cooler, but I kept the three rings remembering the reliability of the three rings. I ran the crap out of that engine in other races and NEVER was down on horsepower compared to other bikes I was racing against. In fact, I had the fastest bike in the club, which I attributed to the rotary valve engine. After about 6 races, I used to swap the bottom ring to the top position (the ring pins aligned) to pick up some extra compression.

If I was racing a chainsaw, I might go to one ring. However, in a day to day work saw, if the piston came with two rings, I'd definitely use two rings.

Anybody no the weight difference between a oem 66 piston and a meteor? I believe the meteor is heavier but I can't remember. Need to order pistons.
288 piston is a decent chunk of aluminum,don't know how much it weighs either,one ring though.

I'll find out the piston weight answers in a week or so

 

[CR888]

Thats a cool post a Terry. I bet you were pizzed coming second to have it sieze, but on the other hand pretty happy having confidence in your tuning ability to build a race winning bike. I like the concept of the rotary valve and the benefits it offers engineers.

My brother and I used to start a moped backwards and try not to dump it riding in reverse.[emoji33]

Meteor 288 is the shiny one, the other is a mahle 066
