Good morning all.
I recently Picked up this battered old SR2 marine unit, its very battered and doesn't run, at all, Since I got it I have started stripping it down and have found the bores and pistons are "20 thou" oversize and the big end shells are "10 thou" oversize.
I suspect that that the crank will need grinding down to "20 thou" undersize and the bores in the cylinders will need taking to "30 thou" oversize.
I have a mechine shop that can do these jobs for me but they have said I would need to supply the pistons for said cylinders, I cant find any good quality pistons out there that are "30 thou" oversize, I have found "40 thou" and "60 thou" oversize pistons but nothing in between, Whats the reason for this or is it just not worth making odd size items for these engines.
As for the rest of the engine, I intend to build it up to an as new standard, obviously in what I understand is Traditional Lister Marine Gray.
For cleaning up all the parts I am going to clean up all the items in my sand blasting cabinet (Powered by my SR2 compressor set)and then mask and spray them in CraftMaster engine paints.
I am very much looking forward to jumping in and getting this project underway and I really hope anyone who reads my posts finds them enjoyable and informative.
