 [attachment=70310]IMG_1342.jpeg[/attachment]Hello all.

Following on from my 'Why two track gauges....' post, here's the origin of my query.
This unit was purchased new in 1952 and delivered to a property near Dunedoo (Dunny-doo) in central west NSW (New South Wales), Australia. It remained there until I bought it in December 2022 from the original owners son. Fortunately it came with the maintenance log, some tools and parts, and a variety of other manuals which I'd be happy to scan and post should they be useful to others. The engine was rebuilt in 1969 and last recorded maintenance was done in 1991 at 4868 hours. It's now showing 5010 hours. It's summer here and typically 28-35 degrees C (82-95F) and the pony runs fine within 3 or 4 pulls, and the main running cleanly so overall I'm really happy with it. No doubt there's work ahead but it's my first dozer and I'll be keeping it original.

Hi Moobi,
The tractor looks in excellent condition and a great acquisition, the bonus is getting the tools and hand books , that's half the challenge. Enjoy the the new toy.

Regards

Ps does the log book have a form number on it usually on the back of the book.

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  [email protected]  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 !

WOW!!! That has to be the best kept D4 I have seen from "down under", as most are very well used up and thrashed! And to have the tools, manuals, etc. too! I really like the service records, reminds me of a KW truck I once owned, as the owner and driver kept meticulous records from day one to the very end; it was like reading a comic book for us as they would make comments about the economy or quirky items.
Glad we finally got to see some photos of your new gem, and glad that you are a new member! Keep on sharing please! JM

Very nice original 6U! I noticed it still has the factory trip-rope clip on the side of the seat, just above the square patent tag - those are usually long-gone. It's currently pivoted froward, but you can see the witness marks where it used to rub further back. When pulling an implement that was operated by a trip-clutch, you would put a loop in the end of the trip-rope and secure it under that clip on the side of the seat; if the implement should happen to come disconnected from the tractor (like a plow striking a rock and releasing the trip-hitch) then the rope would harmlessly come out from under that spring clip and stay with the implement should the tractor continue on a ways before stopping. Much nicer than having the rope actually tied to something on the tractor, or worse yet looped around the operator's hand lol

to have a full set of book is very nice. yours is of similar vintage to our 6u. the L shape bleeder spanner apparently are rare as hens teeth so dont lone it to any one. i do have the service manual for the engine itself. but win some lose some. and heres a tip get rain flaps for the exhuasts particularly the pilot engine or it will rust out and dust the main. and a good idea to make a couple of wedges to support the pilot's flywheel when its not running as it can walk through the bearings well a old cane farmer and bush engineer told me both of those things and cecil would know sadly he's no longer with us.

"i reject your reality and substitute my own" - adam savage. i suspect my final words maybe "well shit, that didnt work"

instead of perfection some times we just have to accept practicality

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
