    Posted: 21 Jun 2018 at 01:24
I recently replaced the seals around the clutch pushrod with O rings on my early V700. After 6 months riding all O rings had migrated out the front of the pushrod near the spigot allowing gearbox oil to migrate as well. I read in Guzziology that the Oring solution is only an option for V700’s with engine numbers greater than 2715. Mines early and is 1505. Will I need to use the cone seals and can anyone explain why? When I fitted the O rings they seemed like a snug fit and the clutch operation was nice.

Hi Griffy, I'm sorry you've had no response to your post. I guess that's because yours is such an early bike that no one is familiar with the problem you describe. My Loops are later models than yours so I'm afraid I don't know the answer. The only advice I would give would be to follow the advice given in Guzziology.
If you do use the cone seals, let us know how you get on.

I'll be parting out a '67 V700 as soon as I have time and will check into this and get back to the group.

I may have worked out the answer. The O ring solution is predicated on a 1mm clearance around the rod. The shaft is 8mm and the clutch push rod has a 6mm diameter. My bike came with a stepped rod and the diameter where it travels through the shaft is 6.5mm which would make the O rings tight. I don’t know if that is the only reason Guzziology state that the O ring solution can’t be applied to early V700’s but it’s certainly a theory. I now have a 6mm rod and will work with that. Any other theories.

You could probably have found some thinner O rings.

Better 5 minutes late in this world than years early in the next.

I've never seen a 4 spd. with a stepped rod, could be something that a previous owner substituted for the original.
