I found a potentially useful FS5W71 rebuilding guide by Derek Garnier that may be of help to me and others: https://drive.google.com/drive/u/0/folders/0ByCvxnHNk90SYzc4N2E1MWEtMzg0MC00YTE4LTkxZGQtM2RjODA5ODA1YjU1?ddrp=1&hl=en&fbclid=IwAR3SqJySd00J_p1bT2-8yPS_4cSaUGl7jBQ-JcNuYgjk3l0QSo7Rb7gA2D4 Part 1: Volume 11, Issue 2 Part 2: Volume 11, Issue 3 Many of the photographs referenced in the above two articles are missing due to space limitations. A complete set of photographs are located here: https://datsun510.com/downloads/ look under FS5W71.zip I'm hopefully picking up a 4-speed on Sunday to part out for rebuilding one of the 5 speeds I have. A local maker space at Case Western University is milling me a right-hand thread, M27x1.0 stake nut. Let's see if I can get this working again by Spring thaw.

I think these hubcaps are aftermarket from National Wheel Covers manufactured by NAMSCO in Bellwood, Illinois although NAMSCO I thought only made reproduction hubcap for domestic cars. Thanks for the rabbit hole.

If I hadn't already purchase a pair of '76 seats for my 260z I'd of likely gone with Miata seats and mounted speakers in them: https://did-it-myself.com/diy-miata-headrest-speakers/

I'm not sure how accurate this is since it should be checked but here's what I've found in regards to parts that match up part numbers between 4 Speed-F4W71B (from Sept. 1971) and 5 Speed-F571B (from August 1976). This suggests that those 4-speed transmissions may be of use if they can be found in good condition. CrossReference 4 and 5 speed.pdf

ZedHead... I'll keep checking the local classified listings as well as attempt to contact the person I purchased the 5-speed from to see what he has laying around. Maybe I'll get lucky. In the mean time, I'm getting a lot of practice taking these things apart.

ZedHead... Are you suggesting that I find a usable 4 speed and use it to rebuild the worn out 5 speed? Or should I just go with a 4 speed in my 260z? Jeff

If you look at my Jan 4th posting, the teeth on my original transmission were sharper, but several of them were snapped off. I looked at that Transmissionpartsdistributors site; however the part is labeled as being for the C version of the transmission. I'm not sure how that differs from the FS5W71B transmission.

I like that DYI rotisserie. Your design or did you find plans for it?

I never heard of these. I'm not sure if I like it, but it is part of Z history. https://forums.hybridz.org/topic/53266-the-primadonna-z-story-56k/

Soaking it with parts cleaner didn't work, A bearing puller/splitter didn't work, Heat didn't work... A 4-inch vice and two pipe wrenches with all my weight on one of them did the trick. The shafts started moving independently and eventually I was able to pull them apart. Zkars, you were absolutely right about the needle bearings. I snapped the tips of two teeth (one shown in the top left of the photograph). I'm assuming I can live with it. If not, I could see if I can find someone to weld some metal onto it. Thanks guys!

I had tried using the bearing splitter/puller clamped just behind the gear marked with the black arrow. It didn't move and I was concerned about damaging the teeth on the gear so I stopped. And yes, the front part appears to be seized to the rest of the shaft. I might try soaking it in degreaser for a while to see if it's just seized due to grit.

Well that 1st transmission was practice and I'm on to my 2nd unit I purchased hoping it was in better shape. I found a few issues but none that the rebuilding kit shouldn't take care of. My question now is how to get this gear cluster apart. On my first transmission, the shaft split into two sections between the black and orange arrow, this one will not budge. From what I can see in the diagram, there should be a snap ring between these two components so until I pull them apart, I'm not going to get any further. Any pointers on how to split it here without doing any damage?

My fuel pressure was close to 5psi at the 4-screw SU's. My mechanic told me to just adjust the pressure regulator screw. I have an aftermarket regulator so I don't know if the original one also works that way. This was a good idea for how to mount an extinguisher. https://www.amazon.com/Bracketeer-Extinguisher-Bracket-Universal-Vehicles/dp/B015G3QXMY I ended up just making my own based on this design for the passenger seat. I've had a couple of wire melt downs when I first purchased the 260z. Sorry about the mess, my Z is a work in progress.

I ended up purchasing a CHANNELLOCK 929 because it has a lock on it. My old Craftsman won't hold the rings open far or secure enough, OEM #25014 won't hold the interchangeable tips securely, and the OEM #25356 interchangeable tip holder broke off. The 929's are 3-4 times expensive so I have my fingers crossed.

Some of the apprehension is gone since I've mostly torn my first one down so I know what to expect. I just picked up an inexpensive parts washer (Performance Tool W54043 ) because this one has lots of dried oil on it. I have to find a GOOD pair of snap ring pliers. Maybe a pair that locks would work.

Well that transmission had an issue. I couldn't get the shaft to spin by hand let alone a drill. I decided to buy it anyway after the seller agreed to accept $200 for it figuring once I tear it down, I can figure out what the problem is and hopefully fix it. The seller insisted that it was working fine when he pulled it out of the donner car last month. He also will switch it out with another one he has if this one doesn't work. Unfortunately, I cannot pull the tail piece off more than an inch or so and for now the front section is stuck to the adaptor plate. UPDATE: I GOT THE TAIL OFF! UPDATE 2: I GOT THE FRONT OFF The main shaft bearings are a little loose so I'll get to use the rebuilding kit.

Thanks for the pointers. I like the idea of using a drill to spin the transmission. That and checking for metal flake in the fluid seems like a good plan.

If you've been following my thread on a FS5W71B with a slipping 3rd/4th, I've disassembled and found numerous worn parts that cannot be replaced. To quote zKars "Holy crap, those teeth are in bad shape. ..You are out of luck as to finding a replacement. Time to look for a new transmission I think. " I found a used transmission on Facebook/market 3 hours away: https://www.facebook.com/marketplace/item/428839345022192/?referralSurface=messenger_lightspeed_banner&referralCode=messenger_banner Is there anything I can do to check it out before I pay for it?

referring to the above photographs, the 3/4th fork pad thicknesses (top, center, bottom) are 4.11, 5.09, and 4.00mm. The center pad has a slight stepped appearance on one side. The 1/2 for pad thicknesses (top, center, bottom) are 4.55, 4.33, and 4.98mm I'm measuring the pad thickness as shown in the photograph.

The fork was tight on the shaft (roll pin intact). I've attached closeups of the 1/2 fork (marked "T") and 3/4 fork (marked "C") with measurements. I'm not sure if there is any path forward if the 3/4 fork needs to be replaced because it appears to be NLA. The measurements are widths. I'll send the thickness shortly. An additional question... The rebuilding kit only came with one set of needle bearings but the transmission has several of them. Should I purchase additional needle bearings and replace them all?

OK, I'm good with the nut issue and I just about have the whole thing taken apart. I could use an opinion on the condition of the 3rd/4th fork condition.

I might just do that. $60 for a nut seems a bit steep. If I still had access to the maker space machine shop I'd try and make some but they're closed until further notice due to C-19. I actually found some M27X1.5 staking nuts but nothing M27X1.0.

Can anyone suggest a source for main and counter shaft staked nuts, with RIGHT HAND threading? I must have one of the earlier FS5W71B's. If they are NLA, can I substitute something else?

https://www.yeggi.com/q/240z/ Good source for printer files. I've printed the plastic clip for retaining the chrome bezel on the door pull of Datsun 260Z and 280Z, 1974-78 and part of a cold air intake.

I've got several parts on my '74 thanks to my son's printer.
