shortening dozer tracks

[fbaurley]

Is it possible to shorten the tracks on a dozer, by taking a link out, when you are out of the adjustment range of the adjuster. The dozer is a case 850.

 

[Sled Puller]

As long as it is not to short with the link out. I would think you would have to go to a shop and have them press it out on the track machine.

I have never heard or seen this done,

but I'm not familiar with Case dozers.



The pins, bushings, and sprocket must be almost wore out completely??

is the right side worn about the same as the left if so than probally it's all worn out. but check your front idler's , you sould be able to put your finger between the roller and the adjuster. hope this helps Ray

I don't think you'll have a enough track to do it but won't hurt to try. Make sure you do both sides unless you like running in circles.

Not familiar with Case as our dealer sucks, but with the brands we have we can put in 1/2 links also to shorten. Are you at the end of your adjuster? It makes good sense to purchase a shop manual on machines you own. Then you don't get bad advice and you have the info you need at your fingertips. Most parts and shop manuals can be had for under $100.

Dont know if all track setups are the same but I helped change out a set of tracks once and we heated the track where the pin went through on a link and drove it out with a BIG sledge hammer and a BIG punch held with tongs. I suppose by doing this to the pin right next to it you could remove that link. That is a lot of work.

Usually there is enough track after a link is removed, aslong as your adjuster is at max. Your local CAT dealer will have a press setup you can rent that should do the trick to dissemble, but It is easer to just use a BFH to assemble.



If the Carrier roller(s) Are mounted to the top of the roller frame then you can also put a spacer under them to raise it. That will also tighen the track, Kinda Crude but cheeper than 15000 for new undercarrage.

We drove pins out with a 1" to 1 1/2" bar about 4'-6' long welded

at right angles to a suitable drift pin. The length and any helpful angles in this handle depend on the materials available and the quality of help, if any, available. Strike it with a 16 or prefer-

ably, a 20# sledge. Pace yourself with a 20 pounder and something will move.



Good Luck,

Mel

Been a while since I messed with tracks. I remember this though. Put the pins in the freezer and heat up the links before you drive em' home.

Something that I had to do a couple of times was to rotate the pins. Because they only wear on one side. It is a job to drive them out turn it 180 degrees and drive it in. But that was what the boss was paying to do.

 

[fbaurley]

So if you rotate the pins, will that shorten your actual chain length, or just take the slop out between the sprocket and pin. By the way, what do they mean by grousers , when refering to dozers.

 

[Ray Davis]

when you rotate the pins. you need to change the sprokets or build them up. grosers is the pads that bolts on the rails that give it traction

 

[Sled Puller]

Grousers weld to the pad, that bolts to the rail or link... Sounds like a song.



You guys turned pins by HAND?????:--)

 

[Deezul1]

Grousers are the teeth on the track that bite into the ground

 

[illflem]

Not sure if this is correct but it always got my idea across. Pads or plates are the track part that rides on the ground, grousers or cleats are the part of the pad that sticks out at 90° for more traction. Street pads used on loaders and excavators don't usually have grousers or they aren't as aggressive. Sometimes people call the pads grousers whether they have the traction bar or not.
