Hi all. So after a day of pulling apart, cleaning, scrubbing, etc I’ve managed to order all the various gaskets and things I need. I did discover that the exhaust was held onto the side of the mower by rust, gunk and sheer bloody mindedness.

Can someone please tell me the size of the old needed to bolt the exhaust back onto the mower?

Do you have the exhaust clamp?

Honestly, any bolt that will fit.

I know I undo the one on my edger with a 3/8 socket. Really anything

Edit, by clamp I mean https://www.outdoorking-forum.com.au/forum/ubbthreads.php/topics/47908/victa-rotomo-specifications.html

Hi Tyler. No I mean the bolt that holds the metal exhaust vent to the side of the engine.

Ok, just to clarify, I had a closer look at the photo and I see yours has the 'ducted' muffler (since its a special). There is also the more common 'bun' muffler which I was referring to.

Unfortunately, I have no idea what bolt for ducted muffler

Hi Scott and Tyler

I think it is a 5 /16 Whitworth bolt 18 tpi (5/16 BSW )





Cheers
