I have several containers of Crankcases, pistons and cylinder. Some I know are TD cylinder and pistons from the 70s when I was a kid. I made the mistake of not keeping the sets together.

Is there a way now to figure out which ones are matched TD cylinders/piston?

The older thin walled cylinder would be the easiest to identify. Not only is the base very narrow compared to stepped wall cylinders from the 70's but the rod has a oil hole in the bottom of it. That's the only oil hole to my knowledge ever placed on the rods which was for the early thin walled TD from the 60's. If your cylinders are newer stepped wall versions, the cylinder should have a stamped #4 either at the base of the cylinder or on the exhaust cutout. Finding which piston was for that particular cylinder will not be so easy. I clean everything well and install the piston pushing it to top dead and it should stick there. When you touch it, it should fall out into your hand.

         Most cylinders have these identification numbers. A #1 cylinder is usually a dual bypass Black Widow. A #2 is a single bypass Babe Bee/ Golden Bee. The #4 is a TD, the #6 is a QRC and I believe a #5 is a .051.

Ive sorted through some of my cylinders. Ive got several of the double slit cylinders that the piston passes all the way through with no resistance.
Are these cylinders junk?
