    Thumb for Cat 311B

    I am considering putting a thumb on my machine but obviously the dealer is too expensive. Since I posses all manner of plasma cutter and welder and a millwright friend, I decided to venture out and make my own. So far I have gone to the hydraulic supplier in the area and they have done custom...

    I want to make the excavator my career.

    :thumbsup Had to get mine unloaded by the guy who brought it because I didn't know what I was doing... Still don't :(

    Sprocket not Working?

    I am trying to figure out how that worked when it was half that bad. That track must be so tight you can play a tune on it.

    Cat 311B sproket/final drive removal

    Today I was finally getting around to rebuilding the final drive and it was a great success that was a near disaster. I had the step by step for the SISweb and I came to the place after the duo-cone seals were on to place the housing on the motor and the step said "install (or place?) housing"...

    Idler removal Cat 311B

    Do you have the labels for each part? Something there doesn't look quite right.

    Idler removal Cat 311B

    Have my track off and I noticed the idler is quite loose. If I am not mistaken there is a bushing that goes on between the axle and the wheel itself? I have the idler out in a position I can see the bin that goes through but I don't want to do anything stupid. My first thought was to punch it...

    Cat 311B sproket/final drive removal

    Out of curiosity, how much does a machine like that cost? I think each scoop would do a home foundation ;)

    Cat 311B sproket/final drive removal

    I know exactly what you are saying, if I were an operator I would not be interested in that machine at all. Luckily I am just a lowly small time developer that realized that buying an excavator is cheaper than paying to get driveways and digging/back filling foundations ... by a long shot. All...

    Cat 311B sproket/final drive removal

    Yeah I have a question, why is Cat so ridiculous? They have everything locked up in random sizes that only they make... went to the bearing place I go when i am rebuilding anything and they couldn't match a single bearing and the place I get gears from said they can't match the gears...

    Cat 311B sproket/final drive removal

    Just to set tell how everything made out, I let the penetrating fluid do it's thing over night and then I came on to the sprocket with a BFH and off it came after about a dozen hits. Then I got rummaging around the final drive bolts and found 2 forcing bolt holes that were filled flush with...

    Cat 311B sproket/final drive removal

    I went at the sprocket with a 10lbs hammer and it didn't seem to "shock" it at all. I don't recall seeing any extra threaded holes and I did try to use my bucket to turn the sprocket off the holes to be able to use the sprocket bolts as forcing bolts. I have also doused the whole mess in...

    Cat 311B sproket/final drive removal

    Definitely all removed. The cover removed itself, that is how I know it is broke. The casing broke and the outside gears got a bit chewed up. Trying to get it off to rebuild but here I am.

    Cat 311B sproket/final drive removal

    Today I was trying to remove the sprocket off my machine so that I could then get a lighter final drive out. After I was unsuccessful at getting the sprocket off I tried going after the final drive and then worrying about the sprocket later. I ended up giving up after getting all the bolts...

    Cat 311B Final Drive

    8GR is the answer but in any event thank you for the response. That makes my part search a bit more interesting. Any idea where to look for a replacement for that final drive? I have been looking around and have found some but I am just curious if you know from experience where to look? Perhaps...

    Cat 311B Final Drive

    I recently purchased a Cat 311B knowing full well that it had a broken final drive. The ouside part of the casing had a big hole in it but the price was right based on some prices I had to replace it so I bought the machine. The problem i am having now is that I am getting conflicting...
