Modified the propeller for O-320!
Yesterday the new studs along with a reamer and a jig, arrived from Whirlwind. The 200 RV is actually an O-360 propeller and to be able to fit the 200RV to an O-320, the hub flange must be modified. (I did not know that!) The lugs on the crank are smaller but longer than on an O-360.
I had to remove the studs, which went quicker than I expected because there was no loctite on them?! Than I had to ream out 4 of the holes to allow the crank lugs to go into the propeller flange deep enough. After installing the new (smaller) studs and special collar-washers the propeller was ready to go on. Everything fits nicely and the whole job took me about 3 hours. (plus another 2 hours driving around trying to find the right size tap handle).
I am glad that Whirlwind solved the problem this way, because sending the propeller back would have been even more hassle.
Jeremy, from Whirlwind, promised me that all other O-320 propellers, from the group buy, would be modified in the factory and get the right studs on from the start.
For those with an O-360, this is what the crank flange looks like on an O-320.
This is the jig with the reamer in position. They did a real good job on this, everything fitted perfectly.
This is what the holes look like after reaming them out.
Job done, and ..........
........... finally, the propeller on the plane!
I can get on with my cowl now. I hope this has helped other builders, that will not have to do this mod anymore.
Kind regards, Tonny.
