Needed to do a few adjustments to the exhaust before installing the transmission. I ran out of time yesterday all that is left is to top up the trans fluid and test drive.

Nice rebuild. anything special about doing that job, special pullers or methods of pulling (heat/cold)? Lash adjustment etc?

Nice progress!

Where did you get the bearing 'kit' for the tranny, and what reference/documentation did you use to pull it apart? I'm thinking of doing the same this winter.

Any idea where the loose balls went? Did they come out when you popped open the case?

Yes you need a good set of pullers and a press helps. Having such a long output on the main shaft you need to use extenders to pull the bearings and gears. The toughest one was the 5th/rev hub assembly it has a press fit collar on the main shaft. The hub itself is splined to the main shaft.
Nissan service info for reassembly mentions to press the main shaft and counter-shaft into the separator plate simultaneously (very tricky as the geartrain needs to be moved from mainshaft-counter-shaft back and fourth as you press only a small amount each time) with this trans the output is 18" long and counter shaft is only 4" so you need to use different length pressing tools or as I was taught by an old school trans guy to leave the separator plate mounted in the vise insert both mainshaft and counter shaft into their support bearings, pull on output/counter-shaft while using a dead blow hammer to tap on the separator plate, again you need to pull each shaft in equal amounts. The nice thing about the design of this trans is you can see everything, unlike say a Borg Warner where the geartrain gets put inside the case, countershaft has to be placed at the bottom of the case mainshaft gets inserted then you need to lift the countershaft in mesh with main shaft while not dropping any of the needle bearings or thrust washers!

I got the kit from a local transmission supply place, helps to have knowledgeable people to obtain the parts as I priced out the bearings separately and would have been twice the cost!
I used All Data as a basic resource I have done a few in my career so wasn't to afraid to tackle. This service does require special pullers and a careful organized fashion so no parts will be put back on in the wrong direction.(very easy to do)

Yes there were those missing parts that did worry me but careful inspection of all the gears/shift components showed no damage. Nice that all those pieces are heavy and fell to the bottom of the case where the magnetic drain plug held them there. I would assume before I got the 240 I got this setup out of, someone at least serviced the trans and removed the big bits! :roll: I guess they put oil back in and hoped for the best! Although this trans was very noisy it still shifted/preformed fine!

Have been putting lots of miles on the car, try to drive it whenever I get a chance... neat to scope out new roads with nice tight corners to work the suspension!

Ya I did see that, I am on another trip, I drove the car up today to Lake Country (Okanagan) even surprised me how well it ran even in 29* heat as we drove through Kelowna.

So I am in the process of getting my speedo working I disassembled the instrument cluster to see if the S-13 speedo will work, in the process I decided to restore the gage lenses. This is ultimately what I would like. As you can see the S-13 gage is larger than the tunnel/housing and some of the increments are covered.
Image
I am using a headlight restoration kit from 3M. The lenses on the right has yet to be prepared, ones on the left have had the first stage of sanding done. The kit has 500, 800, 3000 grit and a polishing compound that you put on a sponge and finally a wax to protect the lense. as the lense was not in too bad shape I decided to start with the 800 grit then used the 3000 and polishing compound and wax
Image
Close up view of lense after the 800... this is a little nerve racking as you are putting scratches in the lense and at this point in the process looks like it is ruined!
Image
Here is a close up of the lense after using the polishing compound.
Image
Now this one has had the final step which was to use the provided wax in the kit.
Image
Here is the completed and assembled gage cluster, it is hard to get a pic of it without the glare of my overhead lights.
