Title: Removing the rocker shafts 400/4
Post by: McCabe-Thiele (Ted) on November 18, 2020, 03:55:58 PM

My manual states a suitable 10 mm should be used to withdraw the rocker shafts.

Firstly are all 10mm bolts the same thread or is there a fine & coarse option? I have as yet to buy a selection of useful metric bolts so any suggestion as to suitable length is welcome.

I'm going off the Haynes Manual kit shows the 550 as 6mm.

I've removed the first on by putting a close sized bolt in the hole and pushing it to one side so the threads touch - it pulled out with no effort!
