    Power wash bell house and rear end housing of transmission. I try to remove rear end seal for replace to new one, it's hard to get rid of. Using heat gun to heated up, still no luck. It looks like the rubber stick to the metal.

    Looks like your tranny was rebuilt once. The mainshaft nut and counter shaft nut are re-used. That's No No staff. I think you'd better off to find another 71B tranny to think about the cost of replacing broken, cracked gear with syncro rings + bearings. Since you live in SoCal, I think it's easy to find replacement at Junkyard or craigslist.

    Thanks NewZed for your comment. I was afraid of my collar was broken. And if this happens, I'm afraid of to find right part. Also, I want to keep track information where this site mentioned their measurement is wrong. http://www.zparts.com/zptech/articles/trans_swap%20parts/4tobear_specs1.html Also I noticed the bearing for 4 speed and 5 speed is different. I will measure the size again. Thanks!

    Use special tool to remove flywheel As spitz17 recommended, I need to replace crank rear end seal. There is oil leaking. After dropped transmission, I put 2x4 wood to prevent engine tilt. Luckily clutch is same size of the new one that I bought for my previous 240z. Flywheel has some surface rust, I gust I can just scribble off.

    '77 280z FS5W71B Transmission tear down. Compare clutch folk levers and collers between 4 speed and 5 speed. 5 speed is about 37.51mm 4 speed is about 33.28mm 5 speed is about 27.85mm 4 speed is about 24.66mm Gears are really great condition. Need to check Syncro rings wear out size.

    Progress update. I can't find my pipe wrench in my garage, so I bought new one from HFT. 24inch wrench for $12, I feels good deal with heavy metal item! Remove all shocks. I compare the shocks I have. Bilstein F4-P30-0032-MO in Yellow Tokico Blue and original KYB gas shocks front is short and rear is longer. Bilstein F4-P30-0032-MO is shortest. TOKICO TOHZ3016 is almost same length with KYB 361002 without spacer. Bilstein diameter is about 33mm. Tokico Blue and KYB is almost same size 21.28mm. I notice Bilstein Shock has small hole at the bottom of the shock where thehelix112 inserted bar on his Step by Step Coilover conversion thread.

    Just for a reference for wiring of starter. The problem of my transmission is here. Measurement of collar. As this site, state, http://www.zparts.com/zptech/articles/trans_swap%20parts/4tobear_specs1.html the measurement is not accurate. My 4 speed 71B is different size.

    - Remove exhaust - Remove anti-sway bar - Remove front of diff mount - Unbolt propeller shaft bolts - Remove radiator fan - Remove slottle linkage - Drain transmission oil - Remove starter - Unbolt Transmission - Engine bolts Finally, 4 speed transmission dropped last night. I spend too much time not to brake other staff. The problem was clutch withdraw lever spring was bent. That's why I did not get traction. Next steps: - Remove Clutch - Remove flywheel - Replace clankshaft rear seal - Investigate '77 FS5W71B transmission - Install tranny

    Unfortunately, I only got guts of the tranny without bell house. Therefore, can't tell the shape of bellhouse. I might be able to use some gear swapping to "True Z's 71B" from this tranny
  11. tamo3
    Your car looks nice, but can't tell the difference since photobucket.com shows small thumbnail only....
  12. tamo3
    That's going to be great! I can read the detail of the Z in the magazine like this.
  13. tamo3
    Thanks NewZed, Xnke, and Leon for your feedback. I just measure the size last night and find out the unkown transmission is shorter than 71B. NewZed is right! As Xnle mentioned, the syncro ring for 1-2 is bigger than 3-4 as Xnle mentioned.
  14. tamo3
    Thanks Leon for this site. That's really useful information! I didn't know FS5W71B has so many variety of gear ratios.
  15. tamo3
    I realize that if I change main drive gear and counter drive gear with other one, my "unkown" 5th gear seems like useful. If I swap my 5th gear and 5th counter gear to '77 FS5W71B(wider ratio), my Over Drive 5th gear ratio become 0.7515 which is closed to "closer ratio" 5th gear ratio of '81-'83 FS5W71B, which is 0.745. It's good finding. Wider ratio 5th gear is 0.864. I can get better high way millage with this swap. I think my "unkown FS5W71B" 5th gear and counter gear of 5th are interchangeable with wider ratio of FS5W71B. Will try this weekend.

    Getting advice from duragg, I figure out my unkown tranny's gear ratio from the counting teeth of gear. Main drive gear = 21 1st = 33 2nd = 27 3rd = 25 5th = 24 Reverse = 36 Counter drive gear = 32 1st = 14 2nd = 20 3rd = 28 5th = 45 Reverse = 15 Here is the formula of how to calculate gear ratio. Gear ratio = (main driver gear) divided by (counter drive gear) 1st Gear ratio = (1st gear) divided by (1st counter gear) divided by Gear ratio Thus, Gear ratio = 21 / 32 = 0.65625 1st gear ratio = 33 / 14 / 0.65625 = 3.591836735 2nd gear ratio = 27 / 20 / 0.65625 = 2.057142857 3rd gear ratio = 25 / 28 / 0.65625 = 1.360544218 4th gear ratio = main drive gear / counter drive gear / 0.65625 = 1.000 5th gear ratio = 24 / 45 / 0.65625 = 0.812698413 Comparing with close ratio and wide ratio of 71B, my unkown tranny gear ratio is much wider than wider ratio. I think it's not worth to spend more time on this tranny... However, I learned a lot from this tranny and get so much experience and confidence from braking this in a parts. I have '77 FS5W71B tranny. It's wider ratio. But I can install that into Z sooner.

    Found the thread. http://forums.hybridz.org/topic/112772-tranny-gears-wanted-discussion-ratios-gear-swaps/?p=1056030 After calculate gear ratio... 1st = 3.591 2nd = 2.057 3rd = 1.360 4th = 1.000 5th = 0.812 Reverse = 3.657 I'm wondering whether it worth to rebuild this tranny... 1st and 2nd gear is wider than '77 tranny....

    This tranny got from one of member in this forum. He kept bell house for 240SX 71C conversion. I thought this tranny is from 280ZX, but now I'm not sure. I count counter gear teeth. Counter drive gear = 32 1st = 14 2nd = 20 3rd = 28 5th = 45 Reverse = 15 I couldn't find other duragg's thread about the calculation gear ratio from gear teeth. I thought you posted WTB section for 5th gear...
  19. tamo3
    When I count the teeth, Main drive gear = 21 Main 1st = 33 2nd = 27 3rd = 25 5th = 24 Reverse = 36 Counter Gear 5th = 45 Reverse = 15 This does not match with FS5W71B in FSM for '83 280ZX nor '89 240SX FS5W71C. But it match with one of the gear combination listed here. http://mmerlinn.com/catalog/dox_angel/dt_w7b/dtw7b010.htm

    Thanks for your advice! I will make sure to replace Fuel filter before running engine next time! small progress. Finally all the gears are off from the shafts. I need to make sure to memorize the direction of 1st & 2nd gears's syncro. The bearing inside of 1st & 2nd gear syncro has brownish color... rust?? I bought rebuild kit @ ebay looong time ago, before acquired this close ratio tranny. The syncros should be all 4 same thing. but 2 of the looks new, other 2 of them seems like used one....
  21. tamo3
    Thanks duragg for quick reply and advice. I will count the gear tooth and measure the dimmention and check FSM when I get home. Looks like FS5W71B closer ratio CA model is similar to FS5W71C. http://720world.com/forum/topics/how-to-remove-front-case-from?xg_source=activity "Here's my B type from the CA motor: Note that it also has the larger C type forks and thinner 1st/2nd synchro." Compare 71B vs 71C http://zhome.com/ZCMnL/tech/240SX5spd/Transmission2.htm

    I'm currently rebuilding FS5W71B closer ratio transmission. I have several wider ration transmission, and I bought a rebuild kit for wider ratio by mistake. This kit include 4 syncros those are same size. When I pull tranny a parts, I realized that 1st and 2nd gear syncro is different shape. I went to Nissan Dear in San Jose and ask for '82 280ZX syncros and the dear gave me part # 32604-P0100 (RING-BAULK) and he maintained I need 4 of them. Searching web site, http://www.carpartsmanual.com/datsunS30/DatsunZIndex/PowerTrain/TransmissionGears/5Speed/tabid/1708/Default.aspx This site mentioned I need 5 of #45. I'm totally confused. Does anyone know what is the correct parts number for closer ratio FS5W71B syncros for 1st and 2nd gears? Thanks, tamo3

    Just small update. After ring pin is removed, banging mainshaft to remove counter gears. On the mainshaft, there is Over Drive Gear Bushing that prevent me to remove the over drive synchronizer hub and insert retainer. There was a discussion about suitable spark plug. I got B6ES and BPR6ES-11 to compare. For my 280z ’75, B6ES seems to be the good one. Decoding the plug name BPR6ES-11… B: Thread diameter 14mm P: Construction. Projected R: Construction. Register Type 6: Heat rating. Hot (2 – 11) E: Thread Reach 19mm S: Firing End Construction. Standard center diameter 25mm -11: Wide Gap 1.1mm (0.044″) Left B6ES, Right BPR6ES-11 Left BPR6ES-11 with wider gap, right B6ES Left BPR6ES-11 with Register Type tip, right B6ES

    Hi ISPKI, Thank you for your reading my project thread and giving good advice. I was planning to do total clean up for gas tank before put my triple weber. Previous owner filled up gas tank almost full and when I remove old gas, I didn't see any sludge at all. Once tranny is done, I will replace fuel filter and fuel tube before running.
