Caterpillar D6H undercarriage

[truecountry]

Well I have a new project that is replacing the undercarriage on a d6h and pivot bearing maybe shafts its leaning bad towards top frame ...
Any pointers or things I need to know ...It will be my first undercarriage changing new rollers, caps, idlers, sprockets and tracks all caterpillar general duty
I see blade has to come off and cap hoses for angle ..

I see after I remove blade then block up machine and cut tracks off and un bolt sprockets that gives me room to remove undercarriage with a excavator..
I want to turn undercarriage up side down and spray all bolts in kroil ...
