Original Lister Cs Engines / Calculating pulley size
« on: April 27, 2019, 10:52:38 AM »
I need a pulley for the alternator to go with the one on the engine.
I can easily measure the overall diameters, but new pulleys seem to be described in terms of pitch circle diameter.
Is it OK to work with the overall diameter figures?
Then I can just ask for a pulley of the required overall size?
Or is there an important difference, so I need to calculate the PCD of the engine pulley, then order the appropriate alternator pulley also in PCD terms?
I'd need to find out the formula to convert overall to PCD diameters.

The crankshaft has centres drilled at the ends, but they aren't recessed.
It looks as old as the rest of the engine, made in 1953.
14mm is less than 9/16", so the keyway hasn't been widened.

Mine engine was originally part of a Start-o-matic.
Could it be how these were made,  to prevent easy fitment of the heavier flywheels to standard engines?

Original Lister Cs Engines / Keyway width puzzle
« on: April 16, 2019, 08:20:24 AM »
I removed a pulley from my CS1, to put on the other (exhaust) side for driving an alternator.
The key was a loose fit, so I made a new one on my mill/drill.
I was surprised to find the keyway on the crankshaft measures 14mm wide, not the expected 9/16" which is slightly wider.
At first I thought it just wanted some dressing with a file, to remove burrs that made it seem narrower.
But, it really does seem to be 14mm, with no discernible lip after cleaning it up.
It even measures 14mm at the bottom of the keyway, at the extreme end of the crankshaft, so it's not just because of deformation.
I reduced the width of my new key for the part that engages the crankshaft groove, the only way it would fit - OK now.
Is this really a metric sized keyway?

Lots of interesting replies to my query, thanks all.
I went with the big drum system because Lister seemed to have recommended it.
However I do see that over-cooling is a possible unwanted effect.
Anti-freeze I discovered was going to be expensive, but the engine is in a shed, though not an insulated one.
We get a few sub-zero Celsius days each Winter. Is it risky to not use anti-freeze in these circumstances?
I thought to avoid a thermostat to keep it simple. That has appeal.
I regret not using a radiator, I think. I do have one that could be appropriate.
It came from a very old big air compressor, so it cooled air. It has copper tubes with spiky, porcupine-like cooling fins on them.
I think it would do for the Lister, and looks interesting.
For the time being though, I will use the existing drum that I went to some trouble to install.
I'm thinking that temperature could be controlled by throttling the flow at the tank's gate valve.
Water at the bottom of the tank might be too cool, but restricted flow should bring the temperature to a happier level within the engine.
Temp gauge at the top to monitor.
Am I correct in this, or is there something wrong - maybe difficult to maintain a steady temperature?
At this stage I am always with the Lister when it's running, but in future it might be providing back up electric power and need to run unattended for lengthy periods.

My 6/1 is cooled by thermo-syphon from the attached 44 gallon drum.
I can control water flow with the gate valve on the drum's bottom opening.
A thermometer was obtained reading up to 120 degrees Centigrade.
I intend to install it on the lower pipe that brings water to the engine.
Is there a recommendation for the optimum temperature to run the Lister?

I don't know what he's saying, but the visuals are marvellous.

We think alike, Glort.
Permanent markers are my friends.
I use them everywhere, even at work.
It's hard for people to critisize, because the benefits of locally accessible info are obvious.

Good idea, Bob.
I'll do that.

Thank you Bob, Mike & Bruce.

I discovered there are also 2 capacitors tucked under the choke.
I put photos here, hope they can be seen:

I'm happy not to use an AVR if it works OK without one. They are surprisingly expensive.
As they have no battery to charge, it's a mystery to me what they do.

I found a manual, but it's of the type that has several wiring diagram variations, all confusing.
Good news is that there's an old guy lives nearby who used to rewind all sorts of electric machines, who came over to check it out.
He took some coil resistance readings and says it's good prospect, so I will now make up mounts for it, and organise the belt transmission from my Lister CS1.

I have an old Markon model LC28D.
I took covers off to have a look, and saw brushes, slip rings, wound stator and rotor.
Also there was a big coil (choke?) mounted on the frame, and some diodes and two adjustable wound resistors.
What wasn't obvious was a regulator.
Is it normal for this alternator not to use a regulator?
Would the addition of an Automatic Voltage Regulator be beneficial?

I assembled the slip joints with some Permatex copper/silicone that BruceM and others suggested.
Cleaned the surfaces with Acetone, put a bead on the inner surface, 2 beads an inch apart on the outer surface - boy, it's thick stuff, needed some squeezing out of the tube even with a 5mm hole in the nozzle. Then the joints were slipped together.
Left it overnight, started engine.
It's nice to breathe fresh air in the shed.

Mud wasps? Are you in Australia?

I got a piece of silicone hose from a friend.
It has some textile insertion material in it.
I found it very resistant to both stretching and to being compressed down to a smaller ID.
So that's ruled out for my exhaust system, where it would need to cope with differing diameters at the joint.
Unless I can find some with the needed sizes built in, but I'm wasting too much time already...

It's been a couple of days, and no word from the silicone hose suppliers.
Must have been too technical a question for a sales person.
I'll go with the Permatex Cu-silicone stuff in a tube.
Thanks folks.

Viton O-rings are good for high temps.
