Pumpkn210 Posted March 8, 2010 Report Share Posted March 8, 2010 The Goon has been shaking whye underway. As of a week ago it was Really Bad. Was thinkin that it would be an easy U-Joint swap. Called the part store and the U-Joints were $40, they only had one, and they are Crimp Style? :blink: Gotta take the driveline into a shop and have it converted, cause there aren't any of the correct Crinpers in the area (Called Around) Heard that guys have Glued them in before? Lucily Tyler(78B210GTX) gave me the D-line out of his 78 B210, the D-line that came in the 79 210 parts car had been converted to greesable press in U-joints. My question is, Do all Datsuns have these wierd drivelines in them? Also should I have it (Old Driveline) converted to Press in or them snap ring joints? Had alot of dealings with the snap ring type and like them, but are the press in ones stronger? Thanks Dave Quote Link to comment
MicroMachinery Posted March 8, 2010 Report Share Posted March 8, 2010 From what I remember, the B210 has a funky driveline. I went to find U-Joints for my 521 one time, and the local parts house carried them, but in the process, I was told a story by the guy at the counter that he'd had a customer that ended up junking their vehicle(B210) because the U-Joints had gone bad, and couldn't find replacements within reasonable price. Now, I don't know how motivated that particular customer was to keep his Datsun, but that only led me to believe it wasn't an ordinary, "over the counter" item. All I can say is keep sleuthing. We're a resourceful band, and someone will know how to cure what ails ya. Quote Link to comment
Pumpkn210 Posted March 8, 2010 Author Report Share Posted March 8, 2010 Well Im ok for now with the replacement(stock) one out of Tylers B210GTX project. And he gots a redone press-in one for that(from parts car) The drivelines are the same length for the 210 and B210. Did they change to replaceabe ones in the later 210s and 510s that share my chassis? Should I go to press-in or Snap Ring type for my Pumpkn Car? Dont know the Pros and Cons of these type joints. Looked around and found Drivelines NW in Tacoma for the work. Thanks Dave Quote Link to comment
datzenmike Posted March 8, 2010 Report Share Posted March 8, 2010 Had a '76 new and the driveshaft U-joints are pressed in and the holes staked so they can't be removed. The dealler will sell you a new driveshaft is what I was told. Quote Link to comment
Skib Posted March 8, 2010 Report Share Posted March 8, 2010 Ya the Z drive shafts are like that too Mike, you cant replace the joints you just have to get a new one. Quote Link to comment
MicroMachinery Posted March 8, 2010 Report Share Posted March 8, 2010 Nissan didn't have many bad ideas back then, but that's definitely one of em. Quote Link to comment
Pumpkn210 Posted March 8, 2010 Author Report Share Posted March 8, 2010 Just got back from Drivelines NW! They gotta make a whole new driveline :( $352 :o Dang! Thats almost double what I paid for the car! $140 is just labor. Dang, thats expensive! Gonna hafta pace myself on this one :( Quote Link to comment
motavated Posted March 8, 2010 Report Share Posted March 8, 2010 I heard that the early 620's could not be fixed as well. Luckly the newer ones could. Quote Link to comment
Pumpkn210 Posted March 8, 2010 Author Report Share Posted March 8, 2010 On a lighter note he put me in as "Ratsun Racing" so I get a discount, and any others that go in to get parts under "Ratsun Racing" :D Quote Link to comment
datzenmike Posted March 9, 2010 Report Share Posted March 9, 2010 I heard that the early 620's could not be fixed as well. Luckly the newer ones could. Not according to the part numbers. Ya the Z drive shafts are like that too Mike, you cant replace the joints you just have to get a new one. Skip, I had a '79 Cutlass and the u-joints are installed and plastic injected in to hold them. Good thing is you can still use a hammer to remove them and replace with C clips. Anything to save a buck. Quote Link to comment
motavated Posted March 9, 2010 Report Share Posted March 9, 2010 Not according to the part numbers. I'm going to try and prove that wrong. My master welder told me so... But who knows... Not want to argue its just what I heard. Quote Link to comment
datzenmike Posted March 9, 2010 Report Share Posted March 9, 2010 Fine with me. :lol: That's how things are learned. Take a look at most manuals even the factory ones. Look up the main bearing journal size for L16/18/20B and also the Z20/22/24. 5 bolt crank L16/18 are 2.1631" 6 bolt crank L20B/Z20/22/24 are 2.3599" Yet many manuals show many of the Z and even some years of L20B the same as the 5 bolt crank at 2.1631". Even my Nissan '84 720 FSM has the wrong size listed for the Z24. Quote Link to comment
kdennis Posted March 10, 2010 Report Share Posted March 10, 2010 There is a company that makes replaceable u-joints for the "staked" in style. You drive out the cap file down the remnants of the stake. The replacement U-joint is retained by inside snap ring. Datsun/Nissan used several different sizes of staked u-joints. Measure the diameter of you cap and the distance between the ears of the yoke. Make sure the inside of the yoke ears is cast or machined perpendicular to the u-joint cross(needs to be flat so the snap ring seats against it. Here are the sizes available .791 cap 1.285 stack up .867 cap 1.400 stack up .947 cap 1.641 stack up .972 cap 1.641 stack up I run a driveline shop in New York and $352 sounds outrageous.

yello620 Posted March 11, 2010 Report Share Posted March 11, 2010 So who makes these special u-joints?? Quote Link to comment
HRH Posted March 11, 2010 Report Share Posted March 11, 2010 Watts Wheel and Driveshaft can fix that problem in Spokane. And if they can't, I have a Datsun Guru with a fab shop who can probably do it. Staked joints sucked, but they won't stand up to a lathe! If Spokane can do it, there has to be a company on the West side of WA that does it. Check out hot-rod shops, find out who does their custom drivelines. Usually it's not too much to alter a driveline, can't imagine it would be much to adapt a different yoke, or put in a more common u-joint that's replaceable. Quote Link to comment
kdennis Posted March 11, 2010 Report Share Posted March 11, 2010 The staked u-joint replacements I use are made by Rockford driveline in Illinois. I believe the 210 staked shaft uses the .791 cap. Part number is 430-9. I keep 8 or 10 at a time. Shouldn't cost you more than $20.00. The problem with starting with a staked shaft is the tube they use. Most are 2.55 OD. Not a standard tube. Mazda and toyota do the same thing. There really isnt a need to get crazy custom machining parts to fix this problem. A completley new shaft slip yoke to flange should cost about $250. Sounds like alot, but when you consider there are 7 parts to the shaft plus assembly and balance its pretty reasonable. The easiest way to remove the stakes is to just drive the cap past the stakes. As long as you are hitting the yoke in the right place you won't do any damage. Hit the yoke right at the base of the ear down near the weld. Don't hit the tube!! If your not comfortable hitting the yoke, get a Bi-metal hole saw. Modify the OD so its a hair smaller than the cap, place over the cap and slowly cut out the stakes and then drive the cap out. Obviously the hole saw is used without the centering drill. The key to using the replacement joints is the casting of the yoke. If the inside of the ears are not flat do not use an inside snap ring replacement. The miata and the Honda CRV are good examples. the inside of the yoke is at an angle, the snap ring touches in one small spot and is away from the yoke the rest of the way around. If the ring spins it can allow the cap to start to move out of the ear causing the cross to slop inside the caps and the eventually tear out of the yoke. It sounds like an unlikely scenario, but I have seen it twice. If you have access to a good machine shop almost anything is possible. I am as much of a "make it work" guy as the rest of you, but after 15 years of doing shafts I have seen some terrible things happen when a shaft is cobbled together. Good driveline design and fabrication is money well spent when you really think about what the shaft is doing. Feel free to give me a call at the shop. Happy to help if I can. 1-585-458-1520 Kevin Dennis Quote Link to comment

Had a shop put a chev van yoke and spline on my 620. Takes a chevy U joint now. Had drive shaft problems on a trip to Ontario. The drive shaft place gut was cool. Told me to get one from a wrecking yard and he grafted it on. He came in on a Sat and did it in an hour including me taking it off and putting back on. Quote Link to comment
datsunaholic Posted March 11, 2010 Report Share Posted March 11, 2010 That's why I'm glad my 4X4 has Spicer driveshafts. I have a pile of dead driveshafts in my garage, all with failed (or very close to failing) U-joints. Quote Link to comment
Pumpkn210 Posted March 11, 2010 Author Report Share Posted March 11, 2010 Thanks for all the usefull info! I was wondering if there was a datsun driveline that was the same slip and bolt on yokes, that I could have shortened? Maby a 620 or a 510? Dont know the specifics of these autos, and you guys know your shiz! Quote Link to comment
kdennis Posted March 11, 2010 Report Share Posted March 11, 2010 The 210 and 1200 slip yoke is .800 18 spline the 510 is .995 22 on 24 (2 splines missing). Not sure of the stock lengths, but you would for sure have to come up with a slip yoke that uses the .985 cap 1.734 lock up inside snap ring joint that was .800 18 spline. They are available new through power train for 35 or 40 bucks. I know some 1200's came with a replaceable joint 18 spline slip yoke. The flange should be the same male pilot 2.250 2.750 bolt circle.
