Does My Engine have a Slipper clutch?

by Russell Hicks in 912 / 914 Technical Questions 11 years ago

How do I tell without dismantling the engine, if my Engine have a Slipper clutch fitted?
Its a 912UL which I know does'nt have them as standard but when reading through the logbook I think I can make out the words "slipper clutch" mentioned in some servicing details, but the hand-writing is hard to make out.

cheers, Russ

Hi Russell

The only way to tell is to lock the crankshaft with the crankshaft locking pin which is like a long M8 grub screw, and then carefully try and turn the propeller forwards or backwards by 30 degrees.

Holding the end of the prop you will need around 6kgs of force to move it. If it moves quite easy, you need a gearbox service, and if it doesn't move you've not got a slipper clutch.

Cheers Mark
