Conservation/ Maintenance History

On arrival a check revealed that the air start equipment is missing along with main bearing ring oilers and cylinder quill feeds.

Notes from Tyne & Wear reveal that the engine had been converted to start from a Crossley 2hp petrol engine using countershaft and clutch.


The engine had been fitted with a replacement liner but the work was incomplete. The liner required removal and a missing front seal fitting. Drillings for the quills were required and new quills fabricated.

New piston rings were fitted

A new pump plunger was fabricated

Sideshaft bent probably as a result of improper slinging at some point, now straightened and checked.

The big-end was also found to be damaged with distortion in both halves.
