I installed new bushings, that I bought from Lang's, in a spare pulley that I had. The id of the bushings are too small for the bolt to go thru. Am I missing something?

After installing the bushings, ream to size.

Tommy, I bought one on amazon. I believe it cost like $18. It's a very handy thing to have.

Find a small local machine shop. They will have reams and can do the job in minutes. If they charge it will probably be the cost of lunch.

I was up at Langs and I purchased a new fan bushing and shaft. I took the bushing and shaft in hand and tried to assemble them quickly in front of Don. Of course they didn’t fit with a dumb look on my face I looked at Don and he said well you have to machine it.

Use a 2 stone brake hone.

JD, I thought about that but all I have on hand is a three stone hone. Will a two stoner go in a bore that small?

If they are Oilite, do not hone. Only a reamer should be used on Oilite, honing is not recommended by the manufacturer.

The following is taken from the above link

Honing and grinding are never recommended on Oilite® bearing materials. Using these methods on any surface which will become the bearing surface will introduce grinding media and could easily smear the bronze pores sealing the micro-porosity.

My old one was not that loose, really, so I put it back with the new felt and gasket. I will deal with the new ones later. Or someone will.
