Message: <blockquote data-quote="Tazza" data-source="post: 13406" data-attributes="member: 82">Ok, some of you know i'm working on a 751 that got a little burnt... ok, a lot burnt. I finally got a bit of time to pull it down a bit. The engine was pulled a few months back that i got running, the pump i have cleaned and flat plated the swash plates so its good to go.I did have a few problems with water that was in the chaincase...<img src="http://users.tpg.com.au/tazza_/751/152_5296.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />I LOVE my 4 in 1, handy for just about every job, especially lifting.<img src="http://users.tpg.com.au/tazza_/751/152_5299.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Removing axle hub, this was a LOT harder than i thought it would be. Thats 1 x 12 tonne and 2 x 2 tonne hydraulics jacks! When i put pressure on the axle hub it needed a good bash with a copper hammer to come loose. That one actually flung off and landed square on top of my foot!!!!<img src="http://users.tpg.com.au/tazza_/751/153_5302.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Axle hub off<img src="http://users.tpg.com.au/tazza_/751/153_5304.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Cracking the bolts inside that hold the sprockets to the axles. The bolts were VERY loose on this machine, should have needed every bit of leverage that pipe had.<img src="http://users.tpg.com.au/tazza_/751/153_5305.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Pressing out the axle. This is needed to pull the inner bearing off the axle. Some may pull the outer bearing and seal out too. Put the axle hub back on but leave it loose so it can be easily removed later.<img src="http://users.tpg.com.au/tazza_/751/153_5309.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Axles are all out.<img src="http://users.tpg.com.au/tazza_/751/153_5313.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Rust on motor carriers. I was worried that the rust got to the bearings, none was there but there was a lot of grit in the axle tubes and the carrier. There was wear on the bearing cups, so they really did need replacing. There was no end play but marks were on the bearing face.<img src="http://users.tpg.com.au/tazza_/751/153_5317.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Pressing out the shaft of the carrier. I don't have a press but i managed to get them out with a hydraulic puller.<img src="http://users.tpg.com.au/tazza_/751/153_5319.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Here is what the hydraulic motor looks like. Most other machines have the same setup, the motors may be a different brand but are essentially the same. This motor was pulled down due to carbon enetering the system. Good thing i opened it as the backup rings inside were broken. Pictures to follow when i get a seal kit and re-assemble it.<img src="http://users.tpg.com.au/tazza_/751/153_5322.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></blockquote>
