[QUOTE="Tazza, post: 1962, member: 82"] Excellent, thank you. I have worked out a way to get the axle seal in i think, i cut 2 bearing cups in half and used 2 hose clamps to hold them together, it did work to an extent on an old seal when i tested it but i'm sure it wasn't square. I would prefer to use the rite tool for the job. As for the bolts, i got a large ring spanner from a friend and held the bolt inside and i made an adaptor that bolts on to the hub. Here is a piccie of it, i hope it is bobcatapproved. [URL]http://users.tpg.com.au/tazza_/bobcat/120_2099.jpg[/URL] I used this to remove the old bolts and they were no where near 450 ft lbs.
