Re-Torque Heads

by Jim agua in 2 Stroke Technical Questions 6 years ago

I was told that there is a requirement to re-torque the cylinder heads. Can someone point me to that documentation?

You will find that in the current 582 Maintenance Manual, see pages 10-2, 11-2.

Re-Torque of the cylinder heads is required only on the air cooled Rotax engines (i.e. 447 and 503). It is not required on the liquid cooled engines.
When re-torqueing on air-cooled engines, re-torque cylinder head nuts one at a time... Do not loosen al at the same time unless you have an alignment
jig installed when re-torqueing..
