Rotax has amended details of the 912/914 series engines which are currently affected by a Magnetic Plug Service Bulletin.
“In short,” says Rotax, “the camshaft and lifters on affected engines could have a higher than normal wear issue due to a finishing problem on a limited batch of lifter mating surfaces. To verify if an engine is affected the engine overhaul/repair history and serial number must be checked against the SB and for those found in the affected range a detailed inspection of the engine magnetic plug performed to verify if in fact a higher wear rate then normal is taking place.”
To help owners diagnose problems and check compliance to this SB, there is a special video on the <a href=’http://www.Rotax-Owner.com ‘ target=’_blank’>www.Rotax-Owner.com</a> website has a special video with expanded instructions.
In updating the SB, the Alert status has been removed and the engine serial number list for affected engines has been reduced to a more defined range. The amended SB now also requires a detailed magnetic plug inspection at each mandatory oil change in accordance to the current engine maintenance schedule/checklist (found in the Line Maintenance Manual) for all affected engines. Again, details are on the <a href=’http://www.Rotax-Owner.com ‘ target=’_blank’>www.Rotax-Owner.com</a> website.
