Engine Bearings

[Timbo267]

Hi,

I am currently in the process of rebuilding my 172 engine. I have pulled the big end and main bearings. I checked the bearings for part numbers etc to ensure I ordered correct replacements. However, they seem to be stamped with part numbers I am unable to find online. The ones listed on RPD and other suppliers do not match. They also have colours listed on them (not sure if they mean anything). Any one able to help me here? Pics below

Big end bearing - 7700110502 (NOIR)
Main Bearing - 7700108709 (ROUGE)

Pure Motorsport stock standard spec big end and main bearings. For a few quid more you could upgrade to ACL too.

The colours will relate to bearing grade and will set the running clearances.
