Hello Matt,
Firstly welcome to the club, we do appreciate you becoming a member.
I see you are located in Gosford NSW, a couple of times when I visited Australia years ago I stayed in the Crown Plaza Terrigal. It was an amazing place and not too far from you.
I'm not sure if you are already a member of an ACMOC Chapter, but check out the Chapters page on the website if you havn't already where you will find details of Chapters as well as an interactive map showing locations of members around the world.  
That's a really nice tractor you have there.
Thank you for your offer to scan the manuals you have for inclusion in the library.
I have just checked the library and we are in need of the following:-

The OMI (Operation and Maintenance Instructions) for the 4A bulldozer,
The Lubrication Oils book,

We do have copies of the others although yours may be cleaner copies.

I myself have never seen an original Tractor Operators Log book, and so if you could scan the covers and main pages (no need for all the detailed pages unless you want to). that would be great.

Regarding scanning the documents, if you have access to a suitable scanner that can scan the pages without splitting the spine of the book that would be great, the format we need id pdf. Otherwise it is possible to scan documents using an iPhone or Android phone. I'm not familiar with the latter, but using an iPhone you can open the notes app, create a new note and select the camera icon and scan up to 24 pages as one .pdf file. If you email the scanned copies to  This email address is being protected from spambots. You need JavaScript enabled to view it.  we can then put together the ,pdf files (if more than 24 pages) and add them to the library..

Regarding your tool collection.
I've been collecting Cat tools for several years and discovered that they are very hard to find mainly because they are not marked "Caterpillar" or "Cat", just the part number and tool manufacturer.
The main manufacturers that we see here in the UK are Armstrong, Billings and VLcheck.

I suspect that in your picture only the open ended spanner nearest the hammer is a genuine Cat spanner and should have a part number of 5B7xx 
The long L shaped tool with the universal drive socket on the end is for adjusting the flywheel clutch and could be a 1B6109
The L shaped wrench to the right of the open ended spanners looks like a 9F22 which is used to bleed the diesel fuel system (bleed points on the filter tower and one for each fuel pump located behind the fuel pumps.
But you will know all this as you have the parts book !
