350 Talk / Re: Bench Testing 350 Oil Pump
« Last post by davis on April 10, 2018, 07:22:10 PM »
The cam with it's shaft moves up and down against the spring as controlled by the rounded end fixed pin. The resulting pump action causes a compression of oil at the cam shaft end. A tiny slot on the cam shaft piston end releases that pressure to the outlet ports while sealing the inlet port from releasing the pressure back through it. The oil distributor shaft is rotating at 1/2 the cam speed, thus in one revolution of the cam slot the distributor shaft rotates 180 degs. to hit both outlet ports alternately. This is why it is important to properly time the cam with the distributor shaft, since each outlet port passage should open up in time with high oil compression. The control lever also has a cam and moves the rounded cam guide to change the cam stroke action against the spring, thus reducing or increasing the volume of flow.

Anyways, that's the way I understand how it works. Hope this helps.

Okay, I wont worry about the movement then. One less part to buy/fix.

Thanks for digging that up. Will be super helpfull.

I was originally thinking blue and white, like the old factory bikes. But the Leopard Moto3 and NYC Norton blue have me thinking. Not settled yet, but if you have ideas.

Thanks for Eds number. I'll give him a ring as soon as I work out the livery.

I found the wiring diagram. Hope it helps. The clutch gear has rubbers in between where it's riveted together. They can be a bit loose sometimes. Mine seems very loose at the moment so I will double check it. Are you going to paint it blue and white? The guy who made the Bridgestone Katana decals is Ed Morgan in Maryland 301.865.5599.

Yep, thats the tach. I'm hoping that the switches are set correctly, since it came with the bike. But if you happen to find the instructions I would be verry grateful.

The silencers are rather short, and I expect that they will not quiet the bike enough. But they will keep me moving forward for now. I'll keep an eye out for something to use in the future.

That big square of material compress down into that little cylinder.

Completed the final - I hope - dry build yesterday. I need to go back and re-read the assembly, and parts manual. When spinning the engine there is a slight amount of resistance every now and again. I don't think it's related to the crank, or pistones. As that assemble spins smoothly without the clutch basket mounted. My thought is ether the clutch, crank gear, or generator gear are not aligned proporly. Or one needs to be shimmed.

I also noticed just a slight looseness of the clutch basket and back plate gear. Should I expect this, or do I need to start looking for a new basket?

Brian I came to the same conclusion last year while sorting out a pump problem. The slot is past the port so how does it pump?!.........Rod

I went to the auction and it is a 1966 Sport 60 with a serious crankshaft-rod noise. It is complete with a lot of bad chrome and it sold for $1000. 6000 miles on it.

Thanks for the confidence Brian. With this small amount of oil pumped I'm thinking oil flow is assisted by the crank case vacuum while the opposite side pressure is shut off by the check valve. Alternating vacuum action could offer a little steady assist in oil flow with check valves being indeed critical.
175 & 200 Talk / Compression reading
« Last post by simonhk on April 08, 2018, 07:57:53 AM »
Hi all,
        What sort of compression readings should I expect on a 175DT? I checked a possible purchase bike today LH 100psi and RH 90 psi, numbers seem low to me.

I like that someone had fake silencers! I use to run the same tach. After a crash the needle stuck and I now run a Scitsu. I don't remember (meaning I can't find it) where I put the Daytona tach but I might have the orig paperwork on how to hook it up. I got it from K&L supply and it's from Shindy products. I'll look for the paperwork. I seem to remember there are some switches under a little plug in the back for firing.

Those holes look pretty good for the stinger! I have some Jolly Moto silencers from a RG500 that were shortened only because the bike was crashed and we salvaged them. I was getting a 98db reading at Barber so well within ok sound levels. Yours look pretty short but they should be quieter than the straight stingers.
