Jacobs Electric Retarder

[imgetnab2]

Greetings All!
I had a mechanic looking at the underside of my 1983 FC today, and
he was checking out the electric retarder. He was familiar with the
Telma brand of retarder and was concerned that there was grease
showing inside the flywheels of the retarder around the driveline
joints. His familiarity with the Telma's was that they had sealed
bearings and therefore, you shouldn't see grease leaking from the
joint.

My retarder is a Jacobs brand, and after looking at it further,
there is a grease fitting that seems to feed the driveline joint.
If that's the case, should I be concerned that there is grease
showing on these joints? I haven't had any troubles with this and
the retarder has worked fabulously to this point. It doesn't seem
to be loose, binding or showing any other signs of bearing wear or
fatigue.

I'd be interested in what others who have these retarders on their
machines have experienced

Thanks as always for the advice!
