Clean, Lubricate and Adjust
(Extended CLA)

Extended CLA means a: clean, lubricate and adjust for cameras that are not serviceable (not usable for filming) due to extended storage. The extended non-operation and storage of the camera causes the lubricating grease to harden and this prevent the camera's spring motor and winding/speed regulator assemblies from operating correctly.

A normal CLA is the annual maintenance check recommended to be performed every year as specified by the manufacturer, Bolex, S.A. of Switzerland for cameras that are in regular use. Most cameras can be serviced every 2 years or so without affecting the camera's performance. Cameras used in dusty or harsh conditions will typically require more frequent maintenance.

A normal CLA does not require motor removal (disassembly from the case) for extended cleaning. Extended CLA candidates are usually on cameras bought from eBay sellers or from estate auctions or from thrift stores.

The large number of these cameras are in very good to excellent cosmetic condition from extended storage, but unfortunately the extended storage also means the oil and grease is either dried up or has hardened such that the camera will not wind and/or run smoothly.
