I have just discovered that my new crank (From India) has no timing marks on it! Any suggestions how I can add my own and get it correct first time!

Thanks, that makes perfect sense. Is it normal for the main bearing shells to want to "spring" out of place? They will not sit in their housing.

I have a mass of new parts from India so time to start reassembly. Any one have any tips on the installation of the crank shaft? it looks like it is going to be a "fun" job. Cheers

This is turning out to be a much bigger job than I expected. Considering a new crank and we go up from there. What are these engines worth? I am not doing this to make money, I am really keen just to have the old girl running again but it would be silly to spend four times what she is worth. I am not planning to sell her anyway.

Some idea of value for an overhauled running original Lister 12 - 2 12 HP 650 rpm please?

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.

Thanks for your message, I appreciate your insite. I will just have to wait for the verdict on my crank before I move on to the next stage.

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.

I tried attaching two photos. The big end would be OK with new shells but the center main bearing and the # 1  main bearing are bad. Not planning of putting her into work but if going to rebuild I think I should do a "proper" job.

I would be pleased to post photos if some could explain how to. Now I have to decide if I get the crank ground and If I do that then maybe it would be worth having the valve seats recut?

Thanks for your input 38ac. I put my gib key puller on (She is made out of 3/4 plate with 9/16 bolts) tighten bolts as hard as I could with a small wrench and smacked the flywheel at 12 and 6 o'clock with my largest sledge. After a few hits I retightened the bolts. In 20 mins I slid the flywheel off. Then repeated the process with the second flywheel in another 20 mins. Crankshaft is now out and I have to decide how much I want to spend on new parts.

Cheers BlackDog

Good day all, this is my first post here so I hope I am doing things correctly.
About 25 years ago I purchased a CS 12-2 in a farm auction as the crank was missing I never tried to start her. Stashed her in the barn for a rainy day. Last week I decided I needed a winter project so I moved her into the shop. I rebult a couple of Petter engines about 40 years ago when in the UK they were on "Dumpers". So not completly green.

So far I have found an oil pipe from the oil maifold laying in the sump, the union nut was broken and the solder repair hadn't lasted. Although she turns over very easily the big end bearings need replacing. Removed the heads and blocks. Valves aren't to bad. A small piece of linner skirt was broken off and also in the sump. A con rod must have conected with it at some time. Bores are excellent and rings appear good. With the big end bearings gone I decided to check the main bearing, she is not good. Oh well "in fior a penny in for a pound". Time to remove the crank.

I had been soaking the gib keys in penetrating oil for a week, had a local machine shop mke me a HD key puller but no luck. I can crack the key heads before they will move, they are welded and waiting for tomorrow.

My question to anyone who has worked on these engines, how hot can you heat the flywheel hub? I have a large "Rose Bud" tip on my torch and had to heat the flat belt drive pully hub cherry red before I could loosen the set screw and remove her. I think this would be a littel excessive for a flywheel!

Any suggestions would be welcolm
