Jacob Posted October 10, 2019 Report Share Posted October 10, 2019 Thanks for the video and picture. That was extremely helpful. Do know where I could get the metal arms that come off the motor, or a set that would fit the Datsun? Arms that hold the wipers that then connect to themselves then attach to the motor. 1 Quote Link to comment

What is wrong with your wiper assembly/transmission? Is it froze up? Is it broke? 1 Quote Link to comment
Jacob Posted October 10, 2019 Report Share Posted October 10, 2019 (edited) No but it really rusted. Looks like the windshield seal has been leaking onto these arms or the seals on the windshield wipers are pretty cracked. Tried taking the driver side assembly out, and see if I could repair the broken bolt that runs up through and connects to the windshield wiper. But now I think I shorted something in the switch or put it back in wrong, because now when I turn on the wiper switch it blows the fuse. reasons for doing this: diver side wiper fell off. Took the end of the bolt with it when it snapped off. Now trying to fix it. Edited October 10, 2019 by Jacob 1 Quote Link to comment
wayno Posted October 10, 2019 Report Share Posted October 10, 2019 Where in Washington are you? Are you saying when the wiper arm fell off it broke the 1/4" post off with it that holds teeth thing on that hold the wiper arms on? When you tried removing the wiper post did you remove the dash? 1 Quote Link to comment

The actual wiper blade arm fell off on the outside of the truck. It’s the teeth thing that fits into the wiper blade arm. I tried JB weld but it didn’t hold. when I tried to remove it I didn’t remove the dash. I’m thinking that I should have. 1 Quote Link to comment
datzenmike Posted October 12, 2019 Report Share Posted October 12, 2019 It's called a pivot. Has a tapered spline that mates to the arm spline. Rotates back and forth. There is an A and a B pivot but they look identical and the only difference I can see to the driver's side (B) has a single linkage to it while the A has one from the motor and shares the one that connects A and B. FWIW the driver's side pivot part number is 26371-14802 but I doubt this will help just get another assembly complete. Be sure to disassemble and use lithium grease on all rubbing parts. I did this on my 710 and the wipers are slightly faster now. 1 Quote Link to comment
wayno Posted October 12, 2019 Report Share Posted October 12, 2019 I don't think you will be able to just change out a pivot post, you will need the whole thing/transmission assembly like Dmike suggested. 1 Quote Link to comment
Charlie69 Posted October 12, 2019 Report Share Posted October 12, 2019 So is the arm bad or the linkage? Quote Link to comment
wayno Posted October 12, 2019 Report Share Posted October 12, 2019 Just now, Charlie69 said: So is the arm bad or the linkage? Charlie, what I think happened is the end of the pivot that holds the arm on broke off. 1 Quote Link to comment
Jacob Posted October 12, 2019 Report Share Posted October 12, 2019 (edited) It’s the part that sticks out to the outside of the windshield that pivots and the windshield wiper connects to. That piece broke and the whole windshield wiper fell on to the hood of the truck. do you guys know where I could get a whole assembly, or a OEM assembly that might fit? have a 1970 521 Edited October 12, 2019 by Jacob 1 Quote Link to comment
thisismatt Posted October 12, 2019 Report Share Posted October 12, 2019 Used from another 521 is your only option, short of finding a NOS one on ebay/etc. They weren't crossed with any other Datsuns. 1 Quote Link to comment

banzai510(hainz) Posted October 12, 2019 Report Share Posted October 12, 2019 yes Ted One needs to lock the wiper arm down correctly otherwise it wont turn. slips but we might be past that now. there are lots of junk 521 out there in somebodys yard. Its always take it all or then it all goes to the dump. just the way it is. 1 Quote Link to comment
wayno Posted October 13, 2019 Report Share Posted October 13, 2019 I emailed/messaged Ted a few weeks ago about something else and have heard nothing yet. I sold my last wiper assembly a couple weeks ago, I have a RHD one but it is different. 1 Quote Link to comment

DanielC Posted November 9, 2019 Report Share Posted November 9, 2019 There are two seal used in the rear axle of a 521. I am trying to use National Oil seal 1973, for the brake plate, or outer grease seal. The inner seal I am using is a National Oil Seal 223542 for the inner, or oil seal. This seal is in the axle housing. 1 Quote Link to comment
