I’ll try this before going for the chop - thanks Bozzer 👍

Don't know if it's already been suggested (haven't read the thread properly ), but 2.5" preload? Tight?

Have you checked that it's not something daft like a 26mm piston seal shoehorned into a 25mm comp' tube?

It was bought as a 25mm seal but mistakes do happen so I’ll measure it when it is stripped in the morning just to be sure.

Thanks,

Ooooh! I'm pretty sure its a 25mm seal, but a pic from the top would lay that one at rest.

I’ll check in the morning Nick. To be honest I’ve had that much fun stripping and reassembling this 77 for my friend I’m dreading it being finished so it would be no bother.

I’ve even posted a wtb for a 97k now. I can have my own to play with then 😎

Thanks,

Darren

Ps, what’s the difference to look at between 25mm and 26mm seals?

Thanks,

As my cohort from sunny Saltburn might say - Thanks folks, I'm here all week.

If you know, you know. I can tell from 100 feet, but thats why I'm a demi-god in these matters.

looking at the back of the seal the hole for attaching to the piston boss is the same on both but the 26 mm has wider "land" around it
