Hello,
I am not sure that piggy-backing onto this thread is best (maybe I should have started a new thread), but I was hoping to understand more about two nice used short shaft drive shafts we have. One appears just as this ebay posting: http://www.ebay.com/itm/USED-JOHNSON-EV … ue&vxp=mtr
If this can be trusted, then obviously the part number is 304933, but in this case I was hoping to understand how the 554314 or the supersession 384961 shafts differ, and does not seem to supersede the 304933 (or vice versa). Our shaft is 27 & 9/16 inches long, .624 inches in diameter, has 14 splines on both ends, and the 1/8 inch diameter hole for the impeller pin is approximately 9 & 3/4 inches center from the pinion end.
The second shaft appears as: http://www.ebay.com/itm/Driveshaft-to-f … Q9&vxp=mtr
Again if this can be trusted, then obviously the part number is 378802. Our shaft is 27 & 9/16 inches long, .624 inches in diameter, has 14 splines on both ends, and the woodruff key slot is approximately 10 inches center from the pinion end. Will this shaft correctly replace the one above if the impeller is also changed (to the style for a woodruff key)? I ask as the center of the woodruff key slot is approximately 1/4 inch closer to the crankshaft end than the pin hole of the first shaft described. Thank You in advance for any correction, confirmation, or additional information that can be provided.
Regards,
Joe
