KTM 690 Cam Chain Tensioner O Ring

Hi all,
Looking for a little help. After recently installing a Rally Raid manual cam chain tensioner I have realised the O ring that creates a seal between the tensioner and the head is missing.

So I have 2 questions:
1. is it nessicary now I don't need to send pressure to the hydrolic tensioner, &
2. how the hell do I get the new o ring in place?

The Rally Raid install instructions said the o ring MUST still be in place or the engine will suffer catastrophic failure...... I just did a 1200km ride without it and all seems well....

Cheers,

Welcome to the forum.

I wonder if the o-ring acts as a spacer to offset the
tensioner the right distance from the head.
