I am going to install a new set of piston rings, will the standard ring compressors work on these motors?
I also want to flatten (lap?) the top of the cylinders. I have a peice of slate that I can use. I was thinking the best thing to do is use 1500 grit sand paper and do a wet sand but I remember a while back there was a thead about this. Can't seem to find the key word. Thank's guy's |

Well, from what I recall.

I haven"t tried the clorox and tooth paste but, yes, glass plate and fine lapping compound for valves works great.

Only works IF you can hold the cylinder PERFECTLY perpendicular to the surface, and cut EXACTLY the same amount of material from each cylinder. Oh, BTW, a sheet of glass isn't flat, not in the precision sense. The Cap'n

I used a piece of granite tile and 1500grit wet sand paper. moved the cyl. in a figure 8 pattern and rotated it several times. It seemed to work real well. I could see where some of the low spots are and was able to get them out.
I am going to use valve lapping compund to lap the cyl. into the head. Nothing crazy, just so it's a good surface for the gasket. What are some good ring compressors. |

Sounds like a good plan. as far as ring compressors go just about any will work if you are loading the piston into the cylinder. then putting whole piston and cylinder assy on the rod and then in the case.
That sounded wierd But I know what I thunk I said. (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif) |

Just doing the top end so the rods are in the case. I think I might be able to load the piston in the cyl., and leave enough pis. out the bottom to reconnect to the rod.
Hey Joe did you ever get my PM about the motor mounts? |
