Im going to use this to document rebuilding a heat riser for an L head as I have to do it on my dads jeep. I already milled out the old bushings and didnt take any photos of course but ill document the install etc.
The only question I have for you guys, the old bushings were 7/16 OD and 5/16 ID the ones kaiser sent my dad are much bigger. ( my guess is something off the shelf and they expect you to drill out your manifold to make them fit). Does anyone have some NOS bushings around for confirmation? I intend to make a leaded brass bushing on my lathe to put into his manifold. Have any of you run into the same issue with the aftermarket bushings?

Did you measure the shaft? I will purchase parts like these only from RFJP or Pete DeBella.

Turn the od of the KW bushings to fit your hole☝️ Also as Scout said do not buy parts like that from KW, go to Ron/Pete/ or Midwest Military…..

Thanks guys, I figured the KW parts were just knurled bushings from McMaster or another catalog store.
My intent is to make new bushings with the brass bushing stock I have. Make them the original size and knurl. This will allow a nice press fit and a sealing fit. I also debated making them from steel, the originals were defiantly a steel the KW are brass of some sort. I will most likley do a nice bearing grade leaded brass or bronze which should prevent the shaft ever freezing in the bushings again.

Ill get photos up this week but I turned bushings tonight. I made them to size and then knurled them which brings them over about 0.010-0.015" the reason for this is the original holes are no longer perfectly round and have some taper. This could be from the factory or from a previous owner. The knurling will allow for the brass to move easier which will allow the bushing to fully fill the holes conforming to the out of round and taper of them. From there I will ream them again just to make sure the press fit did not move the ID too much and then it is ready for assembly

The order is a little crazy but top down,
Photos 1 and 2 are the Kaiser willys bushings that come in the rebuild kit, they measure 0.045" larger than the holes in the manifold. which is way too much material to move.
Photo 3 is my manifold holes cleaned after removal of the original bushing
4- setup and turning on the lathe
5 and 6 is sectioning a pc of 93200 bearing bronze for a pc to turn ( out of order should be above 4)
7,8,9 are me turning the new bushings ( I did knurl the OD however I cannot find the photos on my phone and the ones of the bearing finished are blurry as my phone did that photo video thing)
10 and 11 are me pressing the bushings in with a 5/16 bolt washers and nuts.
once installed I chased with a reamer to remove any issues with out of round and the new shaft went right in.
all done and ready to go.
