I'm in the process of installing new rockers/shafts, and since new supports (#6531) seem hard to come by, I planned to re-use the old ones. After driving one off the old shaft, it's obvious they are deformed and will be very difficult to install. I don't want to damage the new shafts, and driving them on "as is" will make alignment rather tricky. Should I ream/polish them, or is there a method I'm overlooking? Or, should I just track down new ones?

Check with John Mummert.  He probably has good ones.  I see rocker buttemblies all the time on ebay.  May be an option.

That is rocker buttemblies.  The edit function, while working, does not make the changes.  Edited - I don't know what the problem is, but I was careful to enter a s s e m b l i e s this time, but it came out as shown.  ???????????????

I would never guess that it was the filter, but now seem logical.  It changes a*s for butt.  Not much of a dirty word.

the rocker supports are desighned to crush a bit so they are tight on the shaft.tap them in place with a soft hamer,being sure to lube the new shaft,being alum.they wont score the shaft.any i have seen have a slot on the side closest to the head which when bolts ar torqed ther is a clamping action

Daniel, there is an older poston this site where it was suggested that the pedestals be clamped ina vise (on the sides) and this will aid in installing the shafts. Itried this and it helped, although some of the pedestals were stilltight. I have a collection of around 20 pedestals, and a lot are inpoor shape. I really had to search to find 8 that were the samethickness from the bottom of the shaft to the mounting surface. Ihave not been able to find out what that measurement should be. Myshop manual indicates that there is a 0.020 difference in the lowermeasurement versus the top measurement. I found this not to be truefor any of the rocker stands that I have.

I use a Sunnen hone to bring the rocker stands back to a sliding fit on the shafts. An adjustable reamer would also work on re-enlarging the pedestal hole sizes where they are ‘crushed’.

If thy are not to bad an old trick is to warm them up on an old style electric hot plate before you tap them on the room temp shaft. Works well for removing bearing races from hubs and housings and such too.

I found one of my rocker posts to be cracked (from one of the small "crush holes next to the shaft bore - to one of the mounting bolt holes). My guess on what caused it was uneven loosening/tightening of the bolts. Ended up having to make a new one.
