The 912/914 push rod replacement SB mentions loosening the M8 collar cap nut (if necessary) to facilitate the removal of the rocker arm shaft. It also cautions against loosening the M8 collar nut (which is unnecessary for the removal of the rocker shaft).
The SB says to tighten the loosened nut IAW the heavy maintenance or other SI's.
The Service Instruction (change in tightening torque procedures) specifically forbids tightening one nut or one cylinder. It seems that you have to loosen all nuts and go through the process for all the nuts on that side of the engine.
Is this a correct understanding and interpretation?
If not, what would be the correct procedure to restore the correct torque to the collar cap nut if it is required to be loosened to facilitate the removal of the rocker arm shaft?
The previous edition of the Illustrated Parts Catalog shows the torque on that nut to be 22 lb.ft., but again the newest SI changes the procedure.
I am interested in any input from anyone preforming the procedure under the SB.
