I've worked around 100's of mechanics in my life. Some were naturally mechanically inclined and talented. Others, not so much. Andrew demonstrates extreme mechanical aptitude and creative problem solving to accomplish the task at hand. To accomplish that repair in those conditions by himself was highly impressive. Well done!

I have to say it again. One of the things that I admire about Andrew is his persistence!

[@valuedhumanoid6574]

Nice. Those quick grips are magic. From hooking up the hoses on the skid steer to pulling together treads.

[@BruceBoschek]

I'm pretty sure I could have done that repair, given enough time, in a nice, warm shop, with a crane, some repair manuals, lots of good, hot tea and the whole machine cleaned spotlessly before I began. Doing that repair in the wild, parts frozen to the ground and no special tools is the sign of a highly developed human being with endless perseverance and patience. Hats off to another amazing video and the man who not only knows how to use a pipe wrench, but who knows how to edit videos to make them impossible to stop watching. Thanks.

And working in the cold just made the job 3 times tougher with frozen mud plugging all the bolt holes. Hat's off for your perseverance on doing this job on your own!!!!!

SAY WHAT.. I WAS an M60a1 tanker. I was stationed in Ft. Riley, KS.. Were you..? We were out "in the field".. maybe 4 miles away from the barracks doing mock war games. The dozer dug a big hole for us to hide in.. and when we backed out.. one side spun and the other dug in.. SNAPPING the studs that held the rear sprocket on.. So.. With the weight of the track too.. they winched us back a couple of feet to get access to work on it.. Off came the end connectors first.. We had to stand around you mechanics repaired it. 19E gunner\loader I loved drifting them in the motor pool in winter..

Pro tip...next time remove the paint from the sprocket flange. Sprocket segment bolts come loose sometimes even when torqued properly. That layer of paint can break away and the bolts will loosen up. Or it will be fine 🙂

[@toke7560]

Also split the track with the bolts halfway down the sprocket.

Best of luck with the rest of this ambitious project,

[@willielee8218]

Andrew these sprockets are on a tapered spline and when removing them its best to leave the Nut on enough threads so that when they Pop the dont fly of an cause injury, however your doing a great job, Also you should remove all the paint from any face to face parts as they may probably chatter and become loose causing damage to both the sprocket and the segments

[@rushd45]

One of the things that I really like about Andrew's videos is the lack of explaining every step. He knows how to fix things and doesn't need to make sure we hear how he's going to do it. We watch him and it's almost as if we are doing it with him. He sort of makes me feel like I'm part of his team... If there is a problem, he goes about fixing it, the problem is solved and 'that's fixed, let's move on to the next job'.

[@peterhaan9068]

I had forgotten about those O-ring seals that Cat likes to use. In the late 70s I helped with field repair for a Cat dealer. Changing tracks were a pain but relatively easy. Changing sprockets and final drives not so easy. Cat had a puller and installation tools that you could rent that usually came with a hydraulic hand pump and jack similar to a porta-power. As I remember the hand pumps were pretty problematic. I left that world behind in 1980 and never looked back. Cheers Terry

Andrew your ambition to tackle the problems at hand brings out your creative ingenuity.

[@Trydntru]

As you watch Andrew's videos a lot don't realize how much harder it is to run a D4 than say anything over a D7. It has a short track that can create a roller-coaster effect. The operator feels the front of the dozer going down so he pulls up on the blade. Front of the dozer starts goin up so he pushes the blade down, and on and on. A D8 has a long enough track that it absorbs the bumps and gullies. You don't see that kid ever roller-coaster! He's a good operator!.

[@ecleveland1]

Yeah, bigger dozers are much easier to operate than the smaller ones. The longer the tracks make it easier to keep a smooth grade. I used to build fire lines and the longer tracks also have the benefit of not getting stuck as easy. Smaller track dozers can sink in spring heads before you know it. I went to cross a two-foot-wide wash out that was about four feet deep and as soon as my rear sprocket went over the gap the rear of the dozer sank down and I was stuck. It took four other dozers from a D5 to a John Deere 750 to get that little Komatsu D32 out.

[@luvbigiron]

Andrew, I had to laugh when you installed that seal. That is a toric type seal sometimes referred to a metal to metal seal invented by Caterpillar way back. Instructions on installing that seal was to not touch the finely honed metal sealing surfaces with your fingers. The metal part seals the rotating components and the o-ring keeps the preload on the seal face and seals oil in. Will be interesting to see if it leaks. At Cat we had specs for torquing bolts. The specification was preceeded by the number 1 and the letter E . 1E279 was the torque spec. It covered all grades and sizes of bolts. I guess your spec. was 1Eexcavator. That is a Cat part number on the sprocket....an old number from way back. I own a Cat D3C hystat machine from around 2000. Much easier to service the final drive (planetary) and sprocket. That pressed on sprocket is a beast to work on as you showed in your very nice video. Keep up to awesome content. You are one hard working dude. Haven't see how you broke your foot. Stay safe man.

Thank you.

I chuckled also, mechanical seal should have been replaced. Also all bolts and nuts should have been locktited and torqued. But great repair out in the field with limited resources. If it was me I would revisit my repair in the coming weeks to ensure all was good.

To respectfully ad to or correct your answer. Those are mechanical end face seals. Or as we say in Germany gleitringdichtung. It most certainly was not invented by caterpillar but by George j Cooke for use in compressors, but probably became widespread by Ingersoll Rand in pump operations. Touching with your hand won't cause any problems as long as your hands are clean. The facing surfaces are patterned to allow a tiny amount of oil to travel between to cool and lubricate the facing surface so if dirt gets in it destroys the face. There are many different alloys used for different operations but they are due o the complicated alloys all expensive. The main concern is the pressure load on those kind of seals asto much load means they heat up and burn out to quick and can even act as a break so that a hydro motorbike be exposed to extrem load. I have even seen some big old pumps that drive themselves stuck in a matter of minutes dueto excess pressure load during service. Hopefully that didn't come out too know it allI just thought I should share experience. Keep up the good work guys.

@@Teredifa interesting info. Good news here, that one I installed is not leaking

[@luvbigiron]

@@Teredifa Interesting. You are correct. It appears Cooke was given credit for inventing the face seal concept for high speed rotating machinery, pumps mainly. The evolution of the face seal and improvements seemed to focus on the high speed application of the face seal for which there were many contributors. Caterpillar's contribution was refining the geometry and metallurgy strictly for slow speed power transmission like track type tractor final drives. Assembly instructions at the factory was to not touch the finely hones metal surfaces and to wipe them with a type of paper at assembly. Early versions of the slow speed face seal had good life but only if you could keep debris out of the interface.

You would have thought a new seal would have come with the sprocket. I’d probably be sleeping in the shop if I bought the old one. Very cool video as always. Keep them coming.
