Clerget 9J

the Clerget is not a very good design . look how the cam box works . And the master rod system and so on .

I think you may be right Bletchley, the firms in the UK involved with the manufacture of the Clerget engines were rather 'agricultural' and this may well have effected the quality and the part that broke first. It is interesting to see the condition of the Clerget 9J in Lincolnshire, there is a crack in the aluminium of the cylinders. It would be interesting to discover if this is due to poor quality or rough handling.

The Bentley engines were manufactured by engineering firms with more experience of internal combustion engineering.

I have found a Gwynnes brochure on the 9J, waiting for the copy!

All the best,

It is a Gwynne built engine. Complete with data plate. It is locked away in storage at the moment. The next time I access it I will give details.

You may be correct Udo,

My 160 Gnome seems to be a much more stout and simple design compared to the Clerget. Look at the rocker arm bosses for example:
