witch liners for a lister 6-1 to rebore

[saba]

Hello listeroil, thanks for the pointer. I am dutch.

I work abroad so for the coming weeks there's not gonna be much action from my side, but when i'm home i will visit the machine shop with a cilinder block  and ask his opinion. The perkins he did for me he later machined the inside to spec. I will hear what the guy has to say, for them it's just some extra pocket money there normal job is biogas engines, combined heat and power engines.
Here at my job I have equipment that i could give it a try myself but taking a cilinder block in my suitcase is not an option.
Maybee he will give me pointers of what size to order or he will get them himself we shall see.
If I would live nearby I would bring them to mister 38ac was it only to have look at his shop.

Thanks for the input

Bernhard

Just looked again at westwood liners, there's a 1mm finish left so that must be the one.....

The bore size listed  is not what you will have after it is pressed in a block!  It is a size that you can expect it will finish finish if properly installed. NO matter how round or what size a thin wall dry liner is when you purchase it it will be neither one after it is pressed in.  The actual process is you measure the sleeve O.D. in four spots, average the measurements and bore the block several thousands smaller depending on bore size. Because I do a few of them I have a fixture for the CS. After boring the block on the HBM I move the table back and press the sleeve in the block with a 25 ton porta power. Next the top is trimmed and a light deck cut is made on the same machine. Then the sleeve is bored  .010 under size and then honed to size.

Here is a couple videos taken before I made up my block jig. The HBM was built in 1939 and is true within .0002 length of the bed, amazing.

Even Lister's themselves tired of the Chromard process towards the end of Lister CS production, as the later engines which have the modified cylinder block [the crankcase end has a lot less material in the casting, and the 3/4" BSW studs are completely exposed at the crankcase end] are un-plated in the cylinder bore.

It used to be possible [no more] to get finished to size chrome plated dry press liners from here: http://www.laystall.co.uk/cyl-products.php

But you can still get an Indian approximation if you know where to look, and indeed it is the case that some of the Indian manufacturers who don't have the chrome plating ability, buy these liners and press fit them to their own cylinder blocks.

See here for an example of what I mean: https://www.stationaryengineparts.com/Lister-CS-type-Cylinder.html

Did a bit of dry liner installation work myself back in the day, I used to leave an extra 0.001" in the bore, then with a cylinder bore hone we used to knock the high spots off, left by the Van Norman 777 boring bar. This made liner installation so much easier and with a lot less distortion.

Both these companies have obsolete and hard to find parts for old engines. real diesels have the lower postage rates!

A small update on the matter, I got a quote from westwood liners, 38 pounds for a liner. Without tax and postage.

I found another workshop in the nabourhood they charge 60 euro's for boring 10 for pressing it in and another 60 for the finish.He could not give me a price for the liner but he mentioned it would not be breathtaking. So thats 130 euro without tax for the work. Not bad I think. I will think about it I have at least three that are maxed out on size if you add it up it still some money....

If I go ahead I will post the results,
