Curious if there is a "goto" source for re-manufactured assemblies, or someone we trust to rebuild?

It's fairly simple for anyone with a lathe and a few active brain cells to bore the rocker arms out and install bushings to get them back to the correct fit on the shafts, so don't discard the worn ones.

Sounds like a fun project. Know where I can source bushings?

I haven't found any bushing or sleeve near the desired ID/OD (slightly tighter than the OEM .792", not too much metal off the rocker ID).
Anyone care to guess how thin the bushing wall can be (and still re-use the worn rocker shafts)?
Allowing for saw kerf, looks like a single 13" length will make all 12 bushings. | | | | | Joined: Dec 2008 Posts: 1,922 'Bolter | | 'Bolter Joined: Dec 2008 Posts: 1,922 | By coincidence, Harley-Davidson piston pin bushings 1936-* are .792" ID and more than 1" long (long enough for 1 rocker), but that ID allows no room for significant wear on the rocker shaft. Available as cheap as $3.25 each. Sorry, can't find the original OD. | | | | | Joined: Feb 2004 Posts: 29,773 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,773 | I'd suggest using a tool post grinder and reducing the diameter of the rocker shaft a little, and using the same chucking reamer and bushing on the rocker stands as you use on the rockers.
A Federal-Mogul #1394 piston pin bushing fits a 0.875" hole and has a suggested inside diameter of 0.7508". It's 1" long. Use a 7/8" chucking reamer to enlarge the holes in the rockers, and the rocker stands, press the bushings in, and grind the shafts to fit the bushings. That bushing is supposed to fit a bunch of Wisconsin engines from 46 to 94 cubic inches. They're on Ebay for $14.11 each, with free shipping. A little careful shopping could probably locate them for less.

Here's a better deal- - - - -7/8" OD by 3/4" ID oilite bronze bushings for $4.20 each. Press them in, and ream the bushing to a few thousandths under shaft size, then grind the shafts to fit. An ID of 49/64" (0.766") or 25/32" (0.781") would work, depending on how much shaft wear you need to correct. Press a short piece of bushing in from each side, and leave the oil groove and spit hole clear.
