I've got my 1955 640 engine down, it's a sleeved model. The tractor is an ugly workhorse that gets maybe 50 hours use a year. I don't want to carry the block to a machine shop.
I intend to replace the pistons and sleeves with standard and replace the rod and main bearings with the same size that are in it now (0.010). Crank looks good visually. Head will go to machine shop.
What are the pitfalls on these engines? I was hoping that Tisco sleeves and pistons can be made to work without involving a machine shop.
I don't have access to a sleeve puller. Are there any tricks besides welding beads on the inside? I have a flux core welder. The crank being in, kinda makes me nervous about going that route.
Do you guys send a good radiator out to a radiator shop just for the sake of preventive maintenance? Mine looks good and doesn't leak, but I don't want to end up with a Chinese one later.
