Crank Seal Measurements and Equivalents
« on: February 13, 2014, 05:31:39 pm »
Anybody here have measurements for the Echo 10021302830 crank seal (also 10021303930) as used on the CS302S, CS452EVL, and many other older Echos? 

How about an SKF/CR/National/etc part # for it?  It looks to still be available from Echo parts sources at the moment, but a generic equivalent would be good to keep in mind as a plan-B.

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

If you knew which bearing fit these then we could come up with a CR seal
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
