redsquarebob 27 #1 Posted August 22, 2014 i need to no how to get it out so i can put a new one in it Share this post Link to post Share on other sites
Racinbob 11,247 #2 Posted August 22, 2014 I've had good success picking at them with an awl. Be careful not to gouge things up. Once you get it off make sure there aren't any nicks or burrs on the shaft and press the new one in with a large washer and short piece of pipe or a deep socket.

rmaynard 15,628 #3 Posted August 22, 2014 It goes without saying that first you have to remove the pulley. Then I always use a spring puller that looks similar to a dental pick. It goes in between the shaft and the rubber. Then a slight twist will hook it in the back side of the seal body. Pull it out, make sure the shaft is smooth around the woodruff key cutout, clean and lube the shaft with oil or grease and slide the new seal on. Tap it in carefully so that it is flush with the case. Share this post Link to post Share on other sites
redsquarebob 27 #4 Posted August 22, 2014 do you know what the seal number is on a 702. and does look like metal ring? Share this post Link to post Share on other sites
rmaynard 15,628 #5 Posted August 22, 2014 Some look like a metal ring, other are black plastic. The part number is in your parts manual. I don't have it at my fingertips because I am not at my desk. Share this post Link to post Share on other sites
redsquarebob 27 #6 Posted August 22, 2014 is the seal availiable at napa? Share this post Link to post Share on other sites
Lagersolut 682 #7 Posted August 22, 2014 In addition to lubricating the shaft I put a piece of electric tape over the key way, also like putting a few drops of 3 in one oil on the new seal . Share this post Link to post Share on other sites
doc724 925 #8 Posted August 22, 2014 Make sure you understand the root cause of the failure before just putting a new one in. It could be that the old one just was worn out. Or it could be that the needle bearing is starting to fail and wobble a bit. Push on the input shaft (up and down, front to back) there should be no movement if the bearing is still good. If there is any movement, your new seal will start to leak in a few months time. P.S. if the shaft is 3/4 diameter, the NAPA P/N is 7410, about $7 also but it is rubber molded to metal, not plastic like the Toro ones Share this post Link to post Share on other sites
doc724 925 #9 Posted August 22, 2014 Oops, I just looked at the bearing and seal cross reference. (first file at the beginning of this forum). The input seal is different than the brake shaft seal. Use the SKF seal number in the reference. NAPA uses the same exact number Share this post Link to post Share on other sites
redsquarebob 27 #10 Posted August 22, 2014 the shaft only pushes in and out is that a problem. i only got a little metal ring out is that the whole seal Share this post Link to post Share on other sites
rmaynard 15,628 #11 Posted August 22, 2014 In and out is okay. The little metal ring should have had a rubber seal attached to it. If it didn't, that's a good reason for a leak. The new seal, available from NAPA is part #NOS7410 My local NAPA sells them for about $5.00 Share this post Link to post Share on other sites
doc724 925 #12 Posted August 24, 2014 Sheesh, only $5.00, up here in MA they are $7.10 (of course that includes tax) Share this post Link to post Share on other sites
