These unusual items are the old and new OHC
timing chain tensioners. The original black one at the top had sat in
this engine for some 30 plus years, with little use.
|
They are renowned for failing if the
engine is not used, simply because they dry out from lack of
oil lubrication. |
With
the engine out of the frame it was a simple job to remove the rocker
cover and replace the upgraded tensioner which Alan bought from the helpful men
at
Benelli-Bauer
in Germany. |
