Jonny they are a dry 3 piece mechanical brake band i just rebuilt a set last summer on the job good news is if you take the top cover and rear covers off and have small hands you can pull them out of the inspection cover. Im sure you took the rear cover off already and made sure the adjusting screw is set correctly and that linkages are working the bands im not looking at a book and its been awhile but i think the adjuster is tighten down light snug and back off 3-4 turns you will want a touch of free play when done. Also there is a slack stud in bottom of brake/steering chamber that has to be adjusted with brakes or removed to get bands out. I relined mine with kit from tractorparts.com around $42 a side if there is fluid in chamber chance is bevil gear seals are out. Also good time to pull out both plugs and wash chambers out with diesel fuel.

As new requests are received , it is necessary to gradually form a response base and post detailed maintenance instructions. This will greatly facilitate those in need of useful advice and answers to their questions.

Hi, Wearion.
Welcome to the forum.

We actually have a technical library section which isn't going very far at the moment due to people not having much spare time to move items and articles there and catalogue them in the respective sections.

www.acmoc.org/bb/forumdisplay.php?9-TECHNICAL-LIBRARY

You wouldn't by some chance be interested in helping to populate this library, would you???????

ANY and ALL capable help gratefully received and appreciated.

Hi all

I am rebuilding the donkey engine on my 3J but unfortunately i do not have a parts manual that covers my serial number, the closet i have is a 3J1 to 3J5000 parts book.
Cutting to the chase, I need the part numbers for:
the two crank shaft bearings
the two crankshaft seals
a pair of head gaskets

Thank you very much in advance

Hi, caterpillarsam.
This part of the forum does not get a lot of traffic. You would do better to re-post this request on the main forum under 'Discussion'. There are some very helpful people there with access to all sorts of answers and literature that I don't have.

Hope this helps.

Consider contacting your local Caterpillar dealer parts department and have the serial number handy. This is what they do every day and have sources for items like this even if they are no longer offered by Caterpillar.

Upon suggestion from Deas, here is a locale to post detailed maintenance procedures. It will be a stuck thread but open for additions.

have you got a owners manual and a serviceman's reference(workshop manual) these books will have the info to nearly all queries. try ebay or a google search to find them.
also ask your question as a topic on the buletin board. you can also search the bb for d4d brake problems or how to adjust d4d brakes

I finally got my D9 home. It started out in Missoula last December and got to Helena 120 miles down the road just as nasty weather hit. So it was unloaded at the local diesel shop/heavy hauler R&R Diesel's yard. The starter bendix blew up right off the bat. I replaced it using tricks I didn't know I had. I started it up and played with it a little bit once in a while and was getting antsy to get it home. When we had a break in the weather so the dirt road to our place was dry enough, R&R had no driver and when they had a driver the road was too wet.  Everything finally came together with enough dry weather to dry the road out. R&R with the BIG rig and 2 helpers in a pickup got it to the subdivision and then took out a section of the trailer to get it to the end of the  narrow winding subdivision asphalt and I had to drive it the rest of the way (half mile) as the the big rig could not navigate the switchback and the road deadends with no place to turn around. My wife Lilian was posted to block the road so neighbors leaving wouldn't get stuck and have to back up and she took these videos unbeknownst to me. I was fearful of tearing up the road but it has a surprisingly light footprint and you can hardly tell where it was except on sharp turns.
