Here are the Cat Publication references for 92E1760.
Parts - XMBP9774 ($115)
Maintenance - SEBU6550 ($28). This only covers basic maintenance tasks. It is NOT a service/repair manual.
Both the above can be downloaded from the Cat Publications web site, or you might be lucky and find used paper copies somewhere for sale online. The prices in brackets above are for a download.

You can find them used on Ebay too.

I agree but believe it or not but I looked and couldn't find either one up for sale right now.
One place I did find the O&M was scribd.com but you would have to sign up for a 30-day free trial in order to be able to download the document.

I've bought several off this company for various machines . You may need your serial number as the transmissions change about 5100 up

Old Magnet might have access to that info. If he doesn’t pitch in then try sending him a PM.
Cat says they are equivalent machines.
I think the 92Es all came with the same transmissions.

The 92E were the same as the 94N. Started out with the old D333C engine and old transmission, then changed later on.

94N books won't work for 92E machines, Bluox doesn't know what he's talking about.
Buy the correct Parts Catalog for your precise S/N, that way you are guaranteed to get all the correct parts information.
There are a vast number of engineering changes over the life of the D7F tractors, and many engineering changes were also dependent on where the tractor was built.
The early D7F transmission has an arrangement number of 9S5250 - this is a physically large transmission, carried over from the D7E. This transmission is a low-speed, high-torque transmission, and it's not a particularly reliable transmission.
The 9S5250 was fitted to tractors 92E0001 to 92E1751 and 94N0001 to 94N5659. This transmission had many modifications over its life to try and improve its reliability, so engineering (and therefore parts) changes happened to it regularly.
At 92E1752 and 94N5660, the transmission system was extensively altered to accommodate the 2P3670 transmission arrangement. This is the much physically smaller transmission from the then-current D6C.
Despite being a physically smaller transmission, this 2P3670 transmission is a much better design transmission, and it runs at a higher speed and lower torque than the earlier 9S5250 transmission arrangement.
The increased operational speed of the 2P3670 transmission comes about because the transfer gears on the rear of the transmission were altered in size to allow the 2P3670 transmission to run at higher speed.
I owned 2 x new D6C's from 1965 and 3 x new D7F's from 1971. I put around 15,000 to 18,000 hrs on all of them. I've forgotten 10 times more than I know about them today, this is the joys of old age.
The early D7F was full of problems, they were gradually improved by Cat, and the later model transmission was the main reason for a major increase in reliability.
The later model D7F (from about late 1972) also gained a big (factory) counterweight under the radiator, this made a big difference in tractor balance for pushing up slopes.

Thanks Oz dozer. I guess I'll just have to keep looking and hopefully one will pop up one day.
Here's what I know for sure.
I have never seen a 93E machine.
I have worked on a bunch of 94N machines.
92E Japan built but it doesn't show up in cat performance book so may be only for Japan market.
That would mean Cat books would be printed in Japanese.
Cat says 92E and 94N are equivalent machines that means the same.
My D7F service book is for 91E 92E 93N 94N .
Looking in T&A transmission book 92E-UP 94N1-94N5659 first book.
94N-5660 UP second book both published 1973.
So my guess would be any 94N parts book below 5660 would work for early transmission and above 5660 would work for later transmission.

The 92E was sold in the Southern Hemisphere, English-speaking nations, such as Australia and NZ, and the 92E parts catalog is readily available in English. I owned 2 x 92E series D7F's and 1 x 94N D7F.
There are three substantial changes to the D7F transmission design and engineering just between 94N5192 and 94N5660, so Bluox is still talking out his ass.
One of the engineering changes was the fitment of a transmission modulating valve, which the early transmissions did not have.
The modulation valve drops the transmission clutch pressure momentarily between gear changes to take the transmission shock out of full throttle gear changes.
Get the parts catalog for your exact S/No, unless you want a world of frustration with wrong parts ordering.

My exact predicament Ozdozer I have a D7F 92E 0657 needs a turbo 94N 0657 turbocharger replacement part no is 9S 8997 will this fit the 92E 0657 would be great if someone could confirm this either way for me as I will have to import one so have to get it right

Good thread. We had a Japanese sourced 950 73J series and the wiring was completely different than the American built 31K series. That’s all I have to offer.

Wayne.D7 - I'm sorry, I don't have a parts catalogue for the early D7F, I only have the parts catalogue for 92E1752-up, which was the changeover point where the 3306 engine gained a separate S/No and Engine arrangement number. Have you tried contacting the turbocharger seller to see if the 9S8997 turbocharger is correct fit for your machine?
There were a number of turbocharger part number changes that I can see, between the first D7F and the D7G, but I'm not sure now, what those engineering changes involved.
DB2 - That's right, the Japanese Cats were built by Shin-Caterpillar-Mitsubishi, a joint venture deal between the main Cat dealer in Japan, Shin Caterpillar, and the Mitsubishi company, and Caterpillar USA.
As a result, all the electrics on Japanese machines are Mitsubishi. They were copies of Delco-Remy equipment, but not necessarily the same. However, the largest proportion of the components, such as starter and alternator could be interchanged with Delco-Remy products. The wiring could certainly be different to the U.S.-built Cats.

The only thing I can suggest is to look at the link I posted for a Parts Manual reference XMBP9774 further up the thread. That is for machines with S/N up to 92E1751 which would include yours.
If you go to the Cat Publications web site you could buy a copy. Not an ideal solution but it would remove all doubt as to the correct P/N for your turbo.
If that is a paper manual what is the reference number on the front cover.?

Nige, the reference number is not on the front cover, the parts catalogue has "Form UMX04015" on the back cover, and the publication is a revision, and it was printed in Japan on 4/75.
This catalogue states on the front cover, it contains no engine information, and the reader is referred to the index, where it says....
"This tractor is equipped with a 3306 engine. For engine parts information use the parts book for 3306 engine, S/No 44V1-up. The S/No on the engine block provides specific engine identity".
