VICKERS MK6B's resto

The two brass sieves are good as is the 6 cross members that hold them in place. They will be used again.

I managed to get the crankshaft out with no issues and it does look good and so does the block. I certainly does have sleeves so that is another thing in my favour.

I'm really happy that 4 of the 6 pistons came out without too much drama but the other two will take a bit more time. I cleaned the top of the pistons and they are all marked 1-6, dated 1936 and the military markings as well so they certainly are originals.

Hello Colin, have been watching the rebuild and am amazed at the attention to detail. Well done!!. Like a lot of us we are all itching to assist and wishing we lived closer. I read the last post in regards to the pistons.

I may be wrong and way off the mark here but I feel from the photos they look much the same as the Rolls Royce "B" series engine pistons. A few little differences as in the expansion grooves in the skirt etc.

Have just overhauled our "B60" out of the Humber and spotted enough similarities I believe to prompt me to make contact.

"B60"
Bore - 3.5 Inch (88.9mm)
Stroke - 4.5 inch (114.29mm)
Capacity - 259.78 cu. in. (4.25 Litres)

If they are close enough to wet your appetite I am willing to post a NOS (0.20 OS) and a Used Standard piston to you for comparison.

I also now the location of ample NOS - Standard - 0.010 OS and 0.020 OS piston sets a lot closer to you than Seymour.

It makes it easier seeing your block is sleeved the only maybe could be the piston Pin location and diameter.

Cheers,

Dave.

Hi Dave, thanks for the offer but I am pretty sure the B60/80 engines have different pistons but as luck is partly on my side I will possibly be able to use 4 of my 6 pistons and just get new liners. I have just put the block in my press and got the last two out and one liner came out with it with relative ease. It is no biggy to get two new pistons made of the same size so I will do that as the last two have very bad pitting on the top and I don't think you could weld them and expect it to hold up to the heat and pressure they are subject to. All in all I am glad to have my engine back and also to be doing it myself.

The Lagonda aficionados seem to use TWR (presumably Tom Walkinshaw Racing) Volvo pistons so that avenue might at least be worth investigating.

And also seem to suggest that sleeving the block creates overheating issues and piston seizures:

TRW, not TWR, is a major automotive parts manufacturer.
