    Cat 963 vs 973 vs 983, Which to Purchase?

    Lots of wisdom expressed my friends. I envy being able to drive the hydostat's with the counter rotating tracks, its the costs and potential costs that have kept me away. Generally my use is just on my place with lots of room anyway. If you thought "gee maybe the D7 would have been better" maybe...

    With a 8.5 pitch I would expect a factory ROPS.

    Track pad bolts

    I saw a demo of a heavy thick walled 6 point impact socket working better than a lighter weight socket. When we poped off some of the 977 pads 1" impact, 3/4" hose plumed straight into the end of the tank, no oil, no heat, no problem. Good tip on giving the penitrating oil lots of time to...

    977 Loader Question

    The bucket looks pretty good but I don't think it fits a newer machine. Selling parts could be slow. If..... you could get it working with just a little investment you could scrap it latter and get most of your money back. These old Gals can eat your time and "your pay check" pretty easy...

    977 Loader Question

    I wouldn't put time and money into a lever steer, especially a big one. It's getting harder to get parts and the big machines eat up more money. The pluss would be Cat parts are better supported than most any other make.

    Mounting bolts on bottom rollers

    Keep in mind that grinding and sanding discs change the whole surface. Big high spots will push back on the grinder and you may not remove all of it. On a fairly big flat surface a sharp file layed flat on it with no handle that is pushed accross it won't bite into it if there is no high spots...

    Mounting bolts on bottom rollers

    Flat file both mating surfaces. If there is a high spot when you bolt down, your holding the tightest on that high spot. When things start pounding it can flatten out that ding on the surface and the mounting bracket may work loose.

    3306 CAT 977 Block Corroded/Engine Rebuild

    I used a good metal repair epoxy in old cast iron pumps with good results. Mega metal, got it from the Exergon welding rep. Sandblasting then cleaning spotless with isopropyl alcohol/acetone would be a good idea. Start the aplication of the epoxy by rubbing it forcefully into the surface by hand...

    Cat 977 Mayday (Blueox/Nige-help please!)

    I sent contact info. With us being so far apart exchanges may not be practical. The machine runs so you can warm it up somewhat and test it somewhat but not fully under load. It had other issues so I took its tracks for use on another machine.

    Cat 977 Mayday (Blueox/Nige-help please!)

    I have a machine with a good trans. ser.#11K12?? I pulled the tracks off last fall. Interesteded in a road trip to get it? Or I could buy your's... I'm short of time but possibly open to adding to the fleet ... I want the 977's to flourish... A 977 can't compete with rear engine counter...

    the largest crawler loaders in comparison caterpillar 983, komatsu D155S strengths defects character

    I have a 1959 IH TD15 Drott skid shovel with a single joystick. It seemed odd at how smooth and efficient it worked next to the 2 stick/2 pedal steering, manual transmission, and over center main clutch lever.

    What else? 977L head gasket replacement

    I called a radiator shop near me and they want the radiator in one piece. So its they look and they deside which is best. They are indeed in the business. Flushing in place is looking like a better idea, but I want to do it, and forget it. Then again if they say new core after trying we get...

    What else? 977L head gasket replacement

    Finally got back to it. Tec showed how once heated up, throttling up would push the radiator to overflowing, throttle down and it's OK. His opinion "we need to rod out the radiator, it's too plugged to do the job". The oil and trans. coolers will also be cleaned out. I see cores are $2500 and...

    tctractors Thanks for pointing out what you've picked up on the job! The time of well frozen ground may be done except for the north sloping area. So Tall tracks 977L’s best time will be next winter. I think 6”x1”tallx½” cleats on the front of triple grousers maybe a good enough ice biter for...

    Picture records are soooo.... good to have in the record. So well said Chris! "A picture is worth a thousand words". Now we are down to the operator.

    Delmer, you have an excellent course of action that doesn't cost any money. Nige, I love the way you dig up the spec's! I'm exhausted... they're picking up the skidder. Shucks....

    Thanks!! Nick and oarwhat Seems new technology has been added to old school experience!!! You've stayed busy! Never heard of sneak a peek hooking up to a big screen that they don't own and want to sell to you. "Proprietary" lol!!!. I guess these worms can be directed to turn corners too. The...

    Thanks to both of you!!! Got off the skidder for the night! All the manuals are in hand Nige! Boy if the answer is not the head I would be overjoyed!!! I'm thinking the Tech has a boom so the hood and nose comes off easily. We can do some testing (before that the Nick temp gun tests by me!)...

    Thanks fest! Just got off the skidder, this logger is doing me a BBBBig... favor! I'm not a motor man much less a diesel guy but is there compression tests for diesels? Should I replace pc cups even if they don't leak or is it best to leave well enough alone? Could open a can of worms, but doing...
