Listeroid Engines / Re: 3k Chinese alternator just stopped mid run
« Last post by tyssniffen on Today at 02:22:39 AM »
ok, I get that you say the wires go back to the windings, but now that I have these little rectifiers, and a nice chunky heat sink, can anyone clue me in a bit more on which wire goes where?  I labeled my current (dead?) one, and my new one still on the bench.  see attached.   

My ability to dig under the box and figure out which wire goes to the windings is a bit low.

Be sure the flywheels go back on the same side they came from due to the offset weight being on opposite sides. There are some NOS parts around but usually at prices for the wealthy. Also be aware of India parts being sold in LP boxes. I wont tackle that subject publicly but if you want to know who and what then send a PM. There are zero quality issues with most India parts that are made in actual factories. Pistons, rings, bearings, valves , fuel injection are all good stuff.

I'm not trying to alter your direction or pull a sales pitch for my parts business, just adding knowledge for you.

The flywheels are the heavy flywheel option. They were usually specified for generator duty but I also suspect the were used anywhere there was a large variable load.

This Lister has massive flywheels with the "kidney" shaped holes, are these normal? Also has her own radiator.

Thanks for all the imput.
I think oil starvation was definitely the problem with the main bearings. The big ends got away with it (almost!) as they scoop up the oil, new shells should fix them. i will get the center main bearing reground and fit undersize shells. I will fit two new main bearing bushings and keep my fingers crossed that I have no problems.

The following photos show how the main bearing bushings had both the srew hole and oil pathed blocked! Completly solid on the LHS which over heated and partial blocked on the RHS. I punched out the plug on the LHS, see photo.

38ac if you have a CS engine parts price list please e-mail to John@wolverinesupplies.com although I would prefer NOS rather than Indian if I can find them, thanks.

Hi Black Dog, the center main bearing can be reground, undersized bearings are available here in 10 thou increments up to minus 40 thou. Not much you can do about #1 bearing as the bush style bearings only come in one size. It might be possible to build up the worn area by welding or metal spraying then regrinding, could be expensive. Here in Australia a replacement crank is listed at six hundred and twenty five Australian dollars. Don`t know what that would be in Canadian Dollars.

38ac would be able to tell you what the wear limits on the crank journals are, don`t forget this is a slow speed engine so the wear limits are quite generous.

I suspect the broken oil pipe you found in the sump has starved some of the bearings of lubrication.

Thanks Bob,
Yes I have all nornally used CS and India clone parts and quite a few not so normally used. Beside standard sizes I also stock oversize pistons and undersized big end bearings. Center mains for the twins are in standard size are on my current order due to ship soon.

Hi BD

FWIW you can see my thread here, onwards: https://listerengine.com/smf/index.php?topic=8320.msg100396#msg100396

Burned babit is always an issue, but nothing that cant be fixed.

Take care.
