Nissan 720 Transmission removal

[Pigwarrior]

Hi sorry if this has already been asked couldn't find it anywhere else on the forum, I have a 4x4 84 nissan 720 4x4 and it looks like a pain to drop the transmission out. I have to remove the engine and tranny so I was wondering if anyone knows if its possible to just pull them both out of the top with an engine crane. Thanks

 

Also any info out there on tranny rebuilds/reconditioning and parts/seals around? I haven't seen much out there online, IK I could just replace it but would be nice to try and rebuild it.

I've dropped the transmission on my 85 4x4 a few times and it is a pain, but it's doable. Yanking the motor and tranny together is definitely the preferred method. There's a good write up in the old Dime Quarterly with step by step instructions on rebuilding - check out Vol. 11 Issues 2 and 3 here: https://drive.google.com/drive/folders/1vg5gUButsNeoYHv737nzCO32lgiMwh_a. There's also series of videos on Youtube showing the complete disassembly and reassembly of a 71B that helped during my first rebuild. First video is here, and you can find the rest on that page - <https://www.youtube.com/watch?v=eTdf7ncLy0A>.

 

Almost all the rebuild kits will be for the FS5W71C but yours should be a FS5W71B, the only real difference being the smaller 56 mm front counter-shaft bearing on the 71B. All the synchros and other bearings should be the same but someone else will correct me if I'm wrong

Thanks glad to know its possible to pull from top those videos seem really helpful cheers

Just checked and looks like I used this rebuild kit for my 85 - https://transpartswarehouse.com/bk133ws-nissan-truck-trans-fs5w71c-2wd-5-sp-transmission-rebuild-kit-84-6-86.html. Once you pull the transmission, measure to see if you have the 56 mm or 62 mm countershaft bearing. This kit comes with a 62 mm so you'd need to source the 56 separately if needed

Is there a problem with the transmission so that you’re wanting to rebuild it?

On a D21...you have to remove all 3 shafts, in the front, remove the cross-members and abunch of other stuff to remove the engine.  I assume that it'd be way easier to pull your trans.
