1981 Datsun 510 U Joint Clip


Recommended Posts

Hi Guys,

I have use the search function here but can't get the solution to my problem, I am trying to replace the UJoints on my 1981 510, I have the shaft down and after looking at the joints I notice that they don't have the normal clips, instead there are some kind of star clips on them

I also look inside the ujoint for the clips but nothing,

Can some one tell me if there is a special tool to get the clip off or is this a non serviceable driveshaf as the one in a previous topic?

 

Thanks in advance.

Those are non replaceable joints. They are staked at the factory. A shop that specializes in driveshafts can remove and replace them but it isn't cheap. New grooves will need cutting so the C clips can fit. After this changing them would be easy. What I did on my B-210 was just get a used shaft from a wrecking yard.

Ok,

Thanks Mike that helps a lot, and it saves time too, I think I will go the wrecking yard direction see if I can find one.  I just sold my 1979 210 wagon but the guy took the engine and transmission to put it on his Spitfire so i will ask him to measure the shaft length and width to see if I can use that.

 

Thank you again

ujoint disassembly

1)Mark propeller shaft and journal so that the origional combination can be restored at assembly.

2)remove snap ring with flat blade screwdriver.

3)Lightly tap base of yoke with a hammer, and withdraw bearing race.

hope this helps . Have a good day

Those may be replaceable.  There are replaceable ujoints for "non replaceable" ujoints.  The retention of the cap on the replacement 

is done with an inside snap ring.  You need to measure the cap diameter and the distance inside to inside of the yoke ear

(as if there was no joint in it).  Refer to the link and see if they make a joint that matches your cap and stack up.

The 510 isn't listed by application, but I believe you will find a match.

The "stakes" are just little areas of displaced metal from the yoke.  You can either grind out the stakes (only the tab of the each little square

that lays over the top of the cap) with a small die grinder and remove the ujoint as usual.  I just force the cap right past the stakes, and then go back in with a rat tail file and remove anything that would keep the cap from centering up upon installation of the new joint.

Out side snap rings require a groove.  Inside snap ring joints have the groove on the cap.

The snap ring goes onto the cap on either side and is up against the flat surface on inside

of the ear of the yoke.  All inside snap ring joints are like this.  Old dodge, the standard

chevy/saginaw/3r inside snap ring joint.  If the inside to inside of the ears of the yoke and the

cap diameter are on the chart, they are replaceable.  no special machining required.
