I bolted my engine back up tonight and the FSM said it should turn easily and smoothly, it felt rough and kinda hard to turn, but i have not bolten on teh flywheel yet so the E-shaft isnt in the right spot yet, but i am wondering how hard it should be to turn.

 

Not that hard, there is obviously some resistance, but you should be able to either grab the flywheel and front pulley and spin it by hand easily or stick a wrench on the front bolt and spin it with one hand, but it will offer up some resistance, minimal though.


Here, watch this video and Rob spins the motor with a wrench on the front bolt....should give you a general idea of how easy it should turn......in the vid its at the 2:30min mark

Actually, just watch the entire video, it's shows how to check the end play.

Sideo,

Do you have the spark plugs installed? If you do, the motor will be harder to turn as it's trying to build up compression. The motor in Rob's video most likely does not have the plugs in and is very easy to turn.

BTW, Rob's video is much clearer on how to set the end play than Rotary Aviation's video.

 

ok thanks guys, the spark plugs are out, but it is definately harder to turn than in that video. im going to bolt on the flywheel andthrust washers bearing and plate after work and see if it gets any easier.

if not, what could i have done wront putting the engine together.
