Cat d3c sprocket

[Drag racer]

Thanks TC sprockets can remove without moving frame.

Drag Racer,unfortunately a clean plug on the other side is no indication that something isn’t going wrong.All it means,that it hasn’t started to fail today.
With final drives,you can remove both track frames yourself in preparation for your specialist coming and only paying him to do the very skilled work.
By having both finals apart at the same time,it’s very common to swap parts from each final to the other in order to wear both sides out evenly.
Clearly any big gear lumps that have broken up are likely scrap,but you never know your luck.I’ve done a few of these on larger D6/D8 and D9 tractors that I own over the years and from experience I can tell that the side you think is allright is allways in worse shape than you expected.
I will also point out,that as an experienced owner,I’ve allways understood it’s wise to get an experienced fitter to take the job on and not try it yourself.It takes experience to know what parts you can and can’t put back into it.Your Cat dealer will simply scrap everything that doesn’t meet their strict tolerances as is their way.They have no choice.
It’s also a dangerous game to play with the tooling.It’s a baby of a tractor,but the pain will be same as a big one if things start flying.
The key here is finding a good man to do the job.
Good luck

I understand what you are saying,I don't lack mechanical skill,social tooling complicates this job,thanks for responding.

Looking for D5 manuals for another forum member in my pile of Cat documents, I found a number of manuals for your machine, including a complete service manual if you are looking for one. I can look at what other documents I have that apply to your machine as well.

I would take the service manual and parts manual if you have 1 or both.

It appears I have the service manual, SENR3800, parts manual SEBP1775-01 and the O&M manual SEBU6155-02.
We should probably get Nige to verify these are correct for your machine. I am no expert but he certainly is!

The downside of having it repaired by a dealer (if that is who quoted you) is that they will only install new OEM parts if you want the repair to carry a warranty.
Doing it that way would cut out the option to reduce the cost considerably by using aftermarket (or even good second hand) parts.
I suppose a lot depends on how many hours/year the machine gets used.

Nige can you verify if these are the correct manuals for My D3C serial # 5kg01070.
Service manual Senr3800
Parts manual SEBP1775-01 ,thanks in advance for your help.

It appears I have the service manual, SENR3800, parts manual SEBP1775-01 and the O&M manual SEBU6155-02.

All three manuals are correct for a 5KG-prefix D3C. As mentioned on the other thread if the SENR3800 manual is complete it should contain a copy of the O&M SEBU6155.

SEBU6155-02 is in the manual as well as a stand alone copy.

Curious if final drive issues are very common on D3B/931B machines and what are the symptoms? My 931B is running good and the oil is nice clean but just wondering if there are any tell tale signs of final drive issues? Sprockets don't appear to have any side to side play.

Others may have more input mine had no unusual noises ,only reason I found problem was changing oil.
