grazapin Posted October 20, 2015 Report Share Posted October 20, 2015 It's time to replace the clutch in my little flyer (4 speed manual) but I'm a little unclear which clutch parts to use. I initially brought it to my mechanic (before I realized I don't have enough available cash to pay a mechanic at the moment) and he said he had some difficulty finding parts and was unsure if the parts he finally found were the right parts. So I checked RockAuto and saw that there is some variation in the clutch kits that they say work on a '75 B210. Can anyone give me some guidance or relate some first hand experience? I guess it doesn't help that I'm not familiar with what some of the clutch specs actually mean. This is where I was looking: https://www.rockauto.com/catalog/x,carcode,1210790,parttype,1993 Here are some examples from the RockAuto page that are throwing me off: 7-1/4; Disc mm 184; Disc in 7-1/4; Splines Dia 13/16; Splines 18 7-1/8; Disc mm 180; Disc in 7-1/8; Splines Dia 1; Splines 18 Disc Size (in) 7 1/8 x 13/16 x 24 Quote Link to comment

datzenmike Posted November 1, 2015 Report Share Posted November 1, 2015 180mm diameter clutch disc Nissan part #............ 30100-H5200 .... about $50 180mm diameter pressure plate Nissan part #..... 30210-N1600 .... 360Kg clamping force. about $100 These are old old prices but OEM from NAPA are close to half these amounts Definitely replace the release bearing (good ones are $15-$20) and because it's so cheap ($5) the pilot bushing. If the transmission oil has not been changed in the last 5 yr./30K miles do it now also. GL-4 90 weight. If there is wetness around the transmission tail a new rear seal is also around $5. This is not a technical or difficult job to do yourself in 4-5 hours. 1 Quote Link to comment

I guess it doesn't help that I'm not familiar with what some of the clutch specs actually mean. http://datsun1200.com/modules/mediawiki/index.php?title=Clutch All of the clutches for the 4spds are the same (b110, b210, 210). 180mm clutch 18 tooth spline, 13/16 shaft. FYI: The clutches for the 5spd can differ but only for the 63a (dogleg) which uses the 24 tooth spline (same as L series). Change out the pilot bushing and throwout bearing while you have the clutch apart. Check the flywheel for glazing or cracking, if it looks good clean it up and maybe very lightly scuff it. If it looks burnt or otherwise warped pull it and have it machined (~50$). The flywheel bolts are reusable. Use Loctite and a torque wrench when putting them back in. I would suggest buying a whole clutch kit as it will (almost always) come with the pilot bushing, throwout bearing, clutch disk, pressure plate, and alignment tool. Quote Link to comment
grazapin Posted November 3, 2015 Author Report Share Posted November 3, 2015 Excellent, thanks for the feedback datzenmike and Dguy210. For clutch kits/parts, are there any brands to avoid? Edit: I think I'll go with this PowerTorque kit since I can get it at my local O'reilly in a day. http://www.oreillyauto.com/site/c/detail/PTQ5/KF53701.oap?ck=Search_kf537-01_-1_-1&keyword=kf537-01 Quote Link to comment
grazapin Posted November 4, 2015 Author Report Share Posted November 4, 2015 Interested too, any updates? Also, what did the mechanic quote you? Mechanic said $870 for worst case scenario which includes $540 labor, $220 clutch kit and $95 flywheel resurfacing. Labor cost is what it is, but that clutch kit seems excessive. The one I bought was $71. Quote Link to comment

grazapin Posted November 9, 2015 Author Report Share Posted November 9, 2015 I got the clutch in and now it's time to replace some of the worn out minor parts I came across in the process. The inner shifter boot (the rubber accordian part that screws to the transmission tunnel inside the car) is torn, and the shifter has always been a bit sloppy like maybe 40 years ago there were plastic bushings at the shifter linkage that have long since disintegrated. Does anyone know of a source for either of these? Quote Link to comment
grazapin Posted November 11, 2015 Author Report Share Posted November 11, 2015 Just in case anyone else needs this info, this is what I found for shifter bushings and boot. This has some good info: http://datsun1200.com/modules/mediawiki/index.php?title=Transmission_Gear_Control If I'd searched around here at Ratsun a bit more I would've probably found the part number for the shifter bushings: 32855-H1010. I was able to have a local Nissan dealer get some for me, but they're kinda spendy since they are only sold in a 5-pack. They charged me $4 each, which is stupid for a tiny piece of plastic, but I won't have to spend time customizing something else to work. If anyone needs some let me know since I'll have 3 extras. The shifter boot is part number 75963-H5000 and is apparently no longer available to dealers. I found this on Ebay for $22.09 shipped: http://www.ebay.com/itm/DATSUN-720-UTE-PICKUP-B210-120Y-COVER-SHIFT-KNOB-BOOT-LEVER-OUTER-/161882039013?hash=item25b0ebe2e5:m:mVYDrpdoaJmlWJlOyC8AxtQ&vxp=mtr It ships from Bangkok so I won't get it for 2-4 weeks. I'll try to report back on whether it's worth buying once I get it installed. Quote Link to comment
datzenmike Posted November 12, 2015 Report Share Posted November 12, 2015 '75 4 speed B210 was an F4W60 or 60 series transmission. It uses the same shifter bushings as the 56 and 63 series and is also the same as the 71B. For one of my 71B shifters I simply got the Dodge van brass door hinge kit. About $7 They are just a hair too large for the pin or the transmission shifter so... One lengthwise cut with a hacksaw and perfect fit. Some have simply crushed in with a vice but the pin hole then needs to be filed out larger. You will likely have to flat file the sides in order to get the shifter down between the shift ears on the transmission. 1 Quote Link to comment
grazapin Posted November 12, 2015 Author Report Share Posted November 12, 2015 datzenmike, Thanks, I saw your original thread with the brass bushings but I don't think it had the photo of the hacksaw cut. If I weren't in the middle of doing clutch, brakes and tie rod ends I might have gone that route, but since the plastic bushing were available I went with them in order to save myself some time. Major upside of doing it your way is you can be sure those bushings aren't going to disintegrate and disappear over time like the plastic bushings. Quote Link to comment
5280Datsun Posted November 13, 2015 Report Share Posted November 13, 2015 So, I verified the part number of the exedy with rock auto, amazon and exedy's site, my mechanic just called and said it wont fit! His english isn't so good, so thats about all I got from him. Any idea why he'd say that? So, here is my issue from my thread. Hoping to jack this thread for more attention.... The diameter of the inside of splines on my clutch disk is larger than what came in the car and will not fit on the trans shaft! I checked the model number on the disk itself and it's NSD030U, clutch kit 06018 from exedy. I am at a loss, I know that there is a 5speed disk that's different this is what is listed. It's got 24 tooth, I assume I need the 18 tooth. UGH!!! Quote Link to comment
5280Datsun Posted November 13, 2015 Report Share Posted November 13, 2015 Ok. I've calmed down a bit... Found a shop to rebuild the old OEM pressure plate and disk, a bit more, but it will be done tomorrow. That way I won't have to wait on shipping and can return the other one to the potential idiots at Exedy/Amazon that shipped and stamp the wrong part (TBD?)! Anyway, they do all sorts of specialty clutches, they had some 66 Ferrari in there rebuilding the whole clutch too since the guy couldn't find one for 2 months! Best part is they are down the street!! Theclutchplace.com Quote Link to comment
datzenmike Posted November 13, 2015 Report Share Posted November 13, 2015 24 spline are 71B and because a dogleg 5 speed will fit any clutch used on any 71B 4 or 5 speed, the Dogleg disc must also be 24 spline. Quote Link to comment
