Couple of outboard motor gearbox casings!!
So, following on from my I thought I'd fixed it, my mate diagnosed scored piston, no compression.Well, I thought I'd fixed it for a while.
Bugger.
I think we all have days like thatSo, following on from my I thought I'd fixed it, my mate diagnosed scored piston, no compression.
So I ordered new cheap Chinese replacement engine, stripped the old one out, took hours, bloody hours, new one in, all back together, this evening, old piston was scored.
So a spring from the chain brake has evaporated during this 36 hour period, not even something I'd touched, but getting the clutch off was an ordeal. I will order one, and I've a couple of unimportant looking bits left over, which I'm at a loss.
I'll post photos tomorrow, just goes to prove I shouldn't be left unsupervised.

The ring thing looks like it goes over the fuel bulb that you press to prime the carb, the other bit looks like a location dowel.

You need 50-60PSI for a tig cooler pump. 2LPM is adequate flow to cool 300A oddToday I sort of fixed my tig cooler.
I bought it from @Richard. on here and it's been progressively getting noiser (and it was far from quiet at any time) in fact it go so noisy, if I wasn't welding at high amps, I wouldn't bother using it.
I took a few sound level measurements before I started and I'm getting over 73dbs at 1m.

It's a very simple cooler, big fan on the pump motor exhausts at the bottom and pulls air in through the heat exchanger and that's about it.

Anyway, I replaced the pump with another one that I bought on here.
Much smaller pump and no fan.
I intend to install temperature controlled fans to keep the noise down.
I also need to look at putting a flow meter and an alarm on it before I start using the Lorch torch I have (yet another forum purchase) I'm using a cheap torch at the moment and if I fry it, a new head is less than a £10 so I can cope with that.
I tried out the replacement pump before I started installing it and it's pretty feable.
It's supposed to be 50m head and 2l/min but I doubt it will push 50 inches.
It's a geared pump and looks unused so I don't know what's going on.
I made a few fittings to fit the existing plumbing.

Put it together temporarily and tried it out.

Everything runs but no return flow from the torch.
There is a simple by pass built in between the flow and return made up of a copper pipe with a restriction in it.

If the pump has plenty of flow this isn't a problem but it certainly is for the replacement and it's just cycling around the bypass.
I closed it off completely and I got a return, not much but it's something.
I tried running a few beads at 200 amps and it seems to work.
The return is certainly hotter than the flow
Even with no fan the water in the tank hardly warmed.
But the main thing is it's now super quiet.

I took the old motor apart and the bearings are completely shot.
Rear bearing is straightforward, but I'm going to need help to get at the front one as it looks like the impeller needs to come off.
I'll post a few photos later.

Ah, it's nice to see a fellow member of the Leftover Parts Club. I suspect that a lot of us are members, whether we admit it or not. I'm OCD enough that if I find a leftover part, I can't rest until I tear everything down again and install it in its rightful place. A couple of weeks ago, I overhauled the carb of my portable generator. After I got it all back together and reinstalled on the engine, I walked back into the shop and spotted two small O-rings lying on the bench where I had been working, which prompted a string of oaths as I brought the generator back into the shop and started tearing the carb off. About that time, spouse walked in and said that she had been cleaning out the kitchen 'junk' drawer and found a couple of O-rings, which she brought out to the shop and placed on the work bench.If anyone knows what these bits are and where they go, I'm all ears.
