Ridge Reamer?

[nytescion]

do i need one to take the pistons/rods out of the top of the block? I'm going to have a machine shop bore the block. Thanks for the help

You have to push them out of the top, yes. But if your having the block bored then you don't have to use a ridge reamer.

A reamer's still used to cut the ridge to get the pistons out. However, it's very rare to find a ridge on anything built either in Japan, or after '85 or so. Or, if rebuilt with Deves rings. Not even the most skilled Origami artist can get them out the bottom.
Your local Advanced Auto shop should have them for borrow if you need one.

This thread is a bit old, but due for revival with this question. I removed the pistons from my old block. I'm not too concerned about this setup because another will arrive soon for a complete swap and this one will be bored.

When I tried using a ridge reamer, the pistons were too caked to seat flat by lowering the reamer against them and I could not hold the reamer level to get an even alignment. The end result was a smooth cut on one side and no cut on the other. There were no instructions with the contraption borrowed from Autozone.

This is the only thread result for the reamer but I would like to see more info on setup and use. Does someone know of a good website or tech article that explains the set and use?

Try this out How do you use a ridge reamer? [Archive] - THE H.A.M.B.

No, I don't really like that explanation. Sorry, but it doesn't really give any description about the actual setting and use. One of the most important parts is getting the damn thing level and I'm not sure how to do it.

I have one of the type that drops into the cylinder and has little feet that press against the wall. I'm not sure how to secure it in a level way.

Good lord, you needed a reamer? Had that motor been rebuilt before? Do you know what rings were used?

I didn't require a reamer to remove the pistons. I did it anyway and it wasn't terribly bad. The engine had 213k without a rebuild but there is a bit of crusties along that small gap. I was thinking of just using the reamer to clean it up and try swapping in some new rings and checking the compression before paying for a refresh job.

They quoted a bit too much around here for my liking... a basic "clean up" job for the same price as would include the pistons and reassembly if I ship it out.

EDIT: I think I'll just use a brush attachment on a drill to see if I can just wipe it all off.
