Can this cylinder be repaired

[Tubs]

Joe
My question about matching the intake port
to the sleeve are answered by knowing their
depth and the lines you have drawn on the
on the cylinder. Your pictures were really
helpful to me in understand how you
accomplish that. Thanks for posting them.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

JoeCB, that’s some “Out of the Box” fixturing!
I presume the cutter was for cutting out the ports
in the sleeve……. not sure how you located the
precise locations to cut though.

Prepare to be boarded!

George E:  Thanks for that idea, which I will perform if alignment is off, after first practising drill/cotter fit on scrap.  On a side note, the piston rings are the same size as Model A Johnsons except for a locating notch to file in one edge.  On Jack Craibs Caille web site there is a brochure on the slow trolling attachment for the Liberty Twin which is very unique and interesting, and I’ve never seen one in person

And , “the rest of the story” …..Just in case you are considering going this way.    I found the receipt for the sleeve from LA Sleeve,  $ 82.00 with shipping.

It appears that 2 cylinders are in the process of disassembly for delivery at this time.

Hi Joe

 

Is that a South Bend heavy ten lathe? Looks to be in good shape.

The lathe is a SB 13″ , the big brother of the heavy 10.  I bought it about 40 years ago from the salvage department at Cadillac Motor Car, here in Detroit where I spent 35 years. Back in those days, before we were overrun by lawyers, the company had an employe salvage sales department. About anything going out could be purchased for the salvage value, including blemished (new) tires, past model stuff like upholstery material, floor matt sets and 5 gallon cans of lacquer paint. Not any more, all that sort of stuff goes to the landfill.

Harry, look at those cylinders closely. I know that there were two styles, there is a significient difference in the port sizes, between older and newer models.

Thanks joe.  I’ll take my old ones along to compare when I pick them up locally at the sellers house. I finished tightening up the rods today.  One was very loose on the crank end. Prior to disassembly, when looking at the pistons through the exhaust ports, one piston would not move when starting to turn the crank, while the other piston moved immediately. Seems odd that only one rod was so worn. The oil holes in the small end of both rods were plugged with carbon. Holes in both ends are 3/32″ dia. Maybe the plugged holes should be drilled larger ?
