Time to replace drive washer?

[Henderson,Eric]

The drive washer should be tested for being true. I have had bad vibration from worn/crushed drive washers. I clamp the engine mounting lug in a vice and put a spinner plate and prop on the drive washer. Try the prop in 5 or 6 different positions to see if it is still true.

I find a small piece of thin leather is even more effective and lasts forever.

Ihncheol, just CA a piece of heavy paper to the backplate of the spinner, and re-assemble.
It will work, even after the knurling is damaged.
It's a great use for those wasted paper tags that come on a baggie of Kwik-Links.

Hi, All,
My 140L scratched brand new Tru Turn 2.5" back plate from last prop loose
(it wasn't running lean, but it did anyway).  The backplate got rough
circles on the back with small chips.
Since the engine was acquired used, I have no idea how find a right time to
replace it. It still has some grooves left, but not sharp.
When do you replace drive washer?

Thanks,

Ihncheol
