shimming engine
Posted: Sun Jul 27, 2014 1:44 pmOK I am confused once again by Sonex instructions. My engine is sagging so I am looking at shimming it.
Aerovee 2.1 manual page 39 states that parts required include - 3/8" ID x 1.25" OD Fender Washer (Qty. 16), ACV-Z01-40.
It also states - "A minimum of two ACV-Z01-40 washers (1/8" thick total, minimum) must be placed against the front bushing.
Being that the Engine Mount Pin is 3/8" diameter, wouldn't the 3/8" washers ride over the pin by minimum 1/8" and compress the bushings?
OK now the Sonex plans call for 1/4" ID x 1" OD x 1/8" Thick Washers.
Again being that the Engine Mount Pin is 3/8" diameter, wouldn't the 1/4" diameter washers contact the pin and compress the bushings only to the end of the pin?
Please tell me what I am missing or the proper install to use.
Thanks!
I plan to be in Oshkosh on Thursday.
