matwood Posted September 26, 2010 Report Share Posted September 26, 2010 I've got this transmission that I am wanting to use for my L20B build but the tail piece is kinda bent up and I'm wondering if it's salvageable. I think it is a FS5W71C but cannot seem to source an overhaul kit for it, only it's brother the FS5W71B. Please advise as to whether or not it is salvageable and whether or not it is indeed a FS5W71C. Where to get parts would also be helpful! :) Quote Link to comment

matwood Posted September 26, 2010 Author Report Share Posted September 26, 2010 as soon as they are done uploading :D my internet is freakin slow.... Quote Link to comment
datsunaholic Posted September 26, 2010 Report Share Posted September 26, 2010 Not a C. That's a common early FS5W71B, 77-79ish. Quote Link to comment
matwood Posted September 26, 2010 Author Report Share Posted September 26, 2010 Not a C. That's a common early FS5W71B, 77-79ish. Well with that said... do you have any advice in getting the tail piece back straight? :/.. findinig parts for the B seems doable. Quote Link to comment
datzenmike Posted September 26, 2010 Report Share Posted September 26, 2010 The bent part is just a dust cover. Hammer into shape..... ...so the outer part of the drive shaft slips between it and the tranny case.... or is it over top? 32135 28600 is the part number from Nissan for the dust cover, about $8. Hammer the old one out and drive the new in. Quote Link to comment
matwood Posted September 26, 2010 Author Report Share Posted September 26, 2010 i dont have a driveshaft so im not sure... haha. that is coming up soon on my list of parts needed.... Quote Link to comment
datzenmike Posted September 27, 2010 Report Share Posted September 27, 2010 For 510? The stock one or any other will need shortening. Be sure to replace that seal in the tranny end. It's only $6 and easy to replace, not so easy in the car, and leaks are a pain. Quote Link to comment
matwood Posted September 27, 2010 Author Report Share Posted September 27, 2010 yeah, for a 510. I have a buddy that shortens drivelines for people on the regular but I don't have a driveline for him to shorten yet.. not ANY 510s here in new mexico hardly... what all should i relace in this tranny in order to get it functioning its best... will just bearings and seals do?

datsunaholic Posted September 27, 2010 Report Share Posted September 27, 2010 Yeah, just bend it back out. I've done it with a screwdriver... THEN replace the rear seal. Don't want to bugger up the new one. Quote Link to comment
matwood Posted September 27, 2010 Author Report Share Posted September 27, 2010 So should I just replace seals and run it till it dies? Or should I give it a healthy rebuild before mating it to my FRESH L20B? Hmm... Quote Link to comment
datzenmike Posted September 27, 2010 Report Share Posted September 27, 2010 Up to you depending on skill level or wallet. Definitely change the obvious rear seal. Install empty and fill with about 2 quarts of GL-4 (NOT GL-5!!!) and change evert 30,000 miles. Never tow, climb steep hills or pass in over drive it will last forever. Quote Link to comment
matwood Posted September 27, 2010 Author Report Share Posted September 27, 2010 My skill level is better than average, I would say. And my wallet isn't really a limiting factor as well, just gotta save a bit if it's toooo much. Would a full blown overhaul give me "my money and time's worth"? Or would it just be something that I should do once it does fail (if ever)? Maybe just the Input/output shaft bearings? I have time, as I'm still saving for wheels and rear coilovers. The only thing that concerns me, really, is the fact that I don't know the history on this tranny at all... Quote Link to comment
matwood Posted September 27, 2010 Author Report Share Posted September 27, 2010 I don't want to create another thread just for a simple question so...... Is this a 510 Oil pan? I neeeeeeed one and this one is for sale! :) Quote Link to comment
Braden Posted September 27, 2010 Report Share Posted September 27, 2010 wow!!! thats right on top of the list of parts or things not to sandblast!!!! dude i would honestly take every single peice of that thing apart and clean it!!! i would be scared to run any of the bearings anymore, yeah sand blasting is easy but dang dude 3 hours with a toothbrush or 5 minutes of sand and 10 hours of rebuild? Quote Link to comment
matwood Posted September 27, 2010 Author Report Share Posted September 27, 2010 so it's probably gonna need a rebuild? lol.... like i said, I am not opposed to rebuilding this thing anywway. Everythinng else power train related is getting a full rebuild down to Stainless hardware.... I have just never messed with a transmission until now... hence me asking questions. BTW, toothbrush didnt come close to cleaning the shit.... anyway.... Quote Link to comment
datzenmike Posted September 27, 2010 Report Share Posted September 27, 2010 Is this a 510 Oil pan? I neeeeeeed one and this one is for sale! :)[/font] Looks like it would be from a truck with the front so shallow. Quote Link to comment
matwood Posted September 27, 2010 Author Report Share Posted September 27, 2010 so this would not work with the steering rack and crossmember of a 510, correct? Do you have a picture of a stock 510 oilpan, mike? Quote Link to comment
datzenmike Posted September 28, 2010 Report Share Posted September 28, 2010 No but the steering is at the back of the motor so the pan bulge will be more to the front and thinner to the back for clearance. Quote Link to comment
Charlie69 Posted September 29, 2010 Report Share Posted September 29, 2010 Matwood, as long as any opening on the transmission was taped off with duct tape before blasting the you should have no problems. That oil pan is definitely a truck oil pan. Contact Fun5ten on the DesertDatsuns Forum (AZ Datsun forum) he probably has one he would sell you cheap. Tell him I referred you. http://desertdatsuns.freeforums.org/index.php Quote Link to comment
