In my thread on "A65 Forensics", I discovered a difference in rocker assemblies between this engine, my bitsa engine, the factory Spares manual
, and comments from... it was either Gavin or Kommando.
The difference involves whether the last flat washer (with a smaller id) goes inboard or outboard of the rightmost stanchion.
As I hope you can see in the photo, with the shoulder of the rocker shaft butted right up against the rightmost stanchion, the oil grooves and holes in the rocker shaft align exactly with the oil holes in the left and center stanchions (which are centered in the stanchions left-to-right). With that small diameter washer on the shaft, inside the rightmost stanchion, the oil grooves and holes in the rocker shaft DO NOT line up exactly with the oil holes in the stanchions.
This tells me that, if there is to be a thrust washer inside the rocker stanchion (which there should be, to keep the thackery washer from gouging the aluminum), it must be of large enough i.d. to slide over the shoulder on the shaft.
This means that: 1. My bitsa is assembled correctly, and 2. I'm missing two thrust washers for this engine. A fourth thrust washer for each shaft is also missing from the picture in the factory Spares manual
, and that I cannot explain.
