Yes that PN is flagged here as NLA.


Just the vendor listed as to size, they not always right or using a different way of measuring the seal.

Thanks

If you look at the seal, somewhere you will find info on what type of seal you have. If no luck, do a google maps search for "bearing" and those shops can either find the part # or else find a seal that fits your tiller. They can find one that fits with just the shaft size and the outer diameter.

outer rubber on seal ruined so no numbers and trying to get exact OD was difficult due to shaft still in and getting calipers in there..Guy at vendor concurred with me on the 1.42 or 1.4387 size.thanks
