Sump plug

(1/1)

Pops400:
This bike hates me....

Is someone playing a joke on me? Drain plug appears to be 9mm hex. 9mm!!! Every set I have has 8 & 10mm, can't find a 9mm anywhere... Not even in a drain plug kit...

Is this right, or am I right in saying it's wrong and it wouldn't have been a hex way back then?!  >:(

Can't even find a local shop to buy a 9mm from on a Sunday...

petermigreen:
From memory so probably wrong, should be a 14mm head hex bolt.

Have you got a Halfords near you, I think they do a brake caliper tool that's a 9mm Allen. If that's what you're referring to.

3/8" is 9.5mm so probably too big. I'd be tempted to go with the mole wrench if you can get it on, hopefully the thread in the sump is OK.

Sat outside Machine Mart waiting for them to open... That engine is coming out today.  >:(
