Looking for D3B pin and bush part numbers and dimensions

Hi Mike,
here you go from a Caterpillar Undercarriage Conversion Guide, Form No PEGP2806, Rev 04, 1991.
Cheers,
Eddie B.

Thankyou for the scan Eddie, my 1989 Cat undercarriage book shows the D3 NC and 931 NC have a bush outer diameter of 1.85", and that is the size I'd need for my 2 Ton chains, not the later beefed up bushes of 1.97" as shown in your book.
All the best
Mike

you will find that the chart lists many options and the MS090-8 has 1.81 bushes, will these not suit for length then ??????????

How long is the MS090-8 bush Eddie, and pin diameter, I can't see that dimension in the books, or am I really going blind? LOL

My 1989 book list the MS090-8 bush as having a outside diameter of 1.85"

Hi Mike,
sorry, that"s about all I can help you with. If the dimensions vary then that is unfortunate BUT, they must be close--maybe need to call W Adams Technical Service and ask for some further clarification--or only other thing is see if you can order 1 each of the pin and bush and find out the expensive way. Maybe a used track somewhere local you can measure.
Cheers,
Eddie B.

This might be of some use....

Thankyou Pete, it looks like the bush is stepped at both ends, unfortunately that will not work in the 2 Ton track link, they need a straight bush, back to the drawing board.

Hi Team,
be aware that there are stepped and straight bushes--stepped for Salt (Sealed and Lubricated Tracks) and straight for sealed only tracks--also known as squeaky tracks.
Cheers,
