put it in the freezer for a few hours then press it in ... you can also use loctite ti make sure it stays put ... if you have too much press fit you can buy dry ice at a hard serve ice cream shop and use it to take the bushing down to 50f deg. below zero. you can also heat up the rod end in an oven to about 300 deg to give yourself some more room for the (shrink fit) |

| Hey man, there is a limit to how much press you can achieve on a brass bush. If you go by the rule of .001" per inch of diam, that is a normal press fit, you won't get a tighter fitting bush by squeezing it more. The bush will just contract and close up the bore which will have to be reamed out to size which makes the press fit slacker. If you expand the rod and shrink the bush to achieve .002" per inch of diameter then you will just close the bore down more and the bush will find it's own size by making the bore smaller. Your biggest problem will be in measuring the bore of the rod and the OD of the bush to get correct sizes. Ian. |
