Lister D Ring Gap

I am about to fit new rings to my shaft drive 'Lister D'

Does anyone know what the ring gap should be??

Thank you
Stephen

Gaps are usually 4 thou per inch of bore for watercooled engines, 6 thou for aircooled. That is for a new bore. However for a used Lister D I would set the actual gap around the 8 thou mark per ring, they will soon bed themselves in.

yes you are bang on! 4 thou per inch is spot on. I gapped my Lister d reverse rotation 3 inch bore = 12 thou and it runs like a dream.

Nice one Pete, I knew you told me in the past the gap but could remember which way round it was so thanks for clearing that up for me.

I dont get a number Stu as I am in the dairy section. Eric Moody will be posting my pass when he returns from the Great Dorst.
