    Need to replace an oil seal on a Jacobsen Greens King reel motor and as luck would have it the last long allen screw ended up being rounded and now looking for any trade secrets on how to get it extracted. So if anybody else has been just as lucky as me what was your trick. Thanks

    Can you take a tap from a tap/die set, litly smack it with a hammer and turn at the same time? Never tried, just an idea.

    Snap on has an extractor set that will have one that will fit perfectly into the head, just a slight bit larger and gently tap it in. Use a socket and turn it out. Hitting a tap is dangerous as they are very brittle. While hard for cutting through still, if you ever broke one off then you know what I mean, you're not drilling it out. They are brittle and shatter easily. I've seen small pieces imbedded into people's arms before.

    Mac, Matco, Sunnex all have them too for reasonable prices. Right tools for the job, priceless!!

    Regards,

    Not sure which model motor you're working with. That said, the older four bolt style must be disassembled to replace the seal. Newer motors need not be disassembled to replace the seal, just remove the snap ring and washer, pop out the seal and replace.

    When I saw the topic I was sure that you would be asking about Par Aide ballwashers. Kenneth Ingram, UMD

    Don't know if this would work in this situation, but you can weld a nut to the top of it by welding the inside of the nut, then use a wrench to unscrew. The heat from the welding will also help loosen it.

    Sometimes you can also get a torx bit and hammer it into the rounded out allen head and it will grab. remember to get new bolts when you get the seal.

    Sometimes depending on how much the part is worth it is better to just take it to the machine shop before you ruin it. They have never failed me yet with the most difficult removals.

    I've done it this wAy too . I'd heat up the area a little with propane to expand the aluminium .if the threads are exposed you can soak it with penetrating fluid . Heat and soak a few times before trying the above . If their is a hydraulic shop near by they usually have a machine shop .

    Brandon: If it is the newer style with a snap-ring, we just tap the seal with an ALL, then drill two screws into it. Easy to remove and install. After we installed a new one it held up for a week then started leaking again. Possible the shaft is just to worn. Thats what happens when your mowers have north of 3500 hrs on it!!

    Thanks for all the advice and assistance. What I ended up doing was taking my Dremel tool and grounded down the bolt head with some of there small grinders. Then had a smaller depth to drill. Started With a smaller drill and moved up in size and eventually what was left of bolt head came out with last drill bit. Then I separated the motor and unscrewed the remaining bolt section. May of taken a little longer but I was happy with the end result.
