Tailshaft Bolts

[mr_rbman]

Trying to take my diff out and no matter what i do the bolts wont come undone, i've tried putting a ring spanner on the end of the spanner and thats not working and i've also tried hitting the spanner with a hammer but that just resulted in a broken spanner!

any ideas would be much appreciated!

Cheers!

Get yourself some sort of penetrant like CRC etc and douse the bolts and give it time to penetrate the threads and loosen them up a bit.

Now use a socket and breaker bar (if you can get one) and put a long piece of pipe on the end of it to get some extra leverage on them.

Or if you had access to a rattle gun....

[mr_rbman]

got the crc on there, cant get a socket on there and theres not enough room under the car to get a pipe on there.

well i've managed to get 3 of the 4 undone but rounded the last one in the process, i'm a bit screwed now and dunno what to do!

[Simon-S14]

if its rounded then yes you've made life hard for yourself. these bolts are a very high tenstile bolt and if your using a poor quality spanner you will round them, or break your knuckels... or both lol.

the trick is to use a LONG 14mm spanner, of good quality, or a short quality one with another one on the end to add leverage. get a mate to shove a long flat head screw driver through the tailshaft uni joint and pull that opposite to you.

since its rounded... you're now going to have to either cut it off with a grinder using a very thin cutting disk, or weld on a bit of steel to the nut, and then put a breaker bar over the steel to undo it.

yes either way its a pain in the arse.

you ca try using a cold chizel.

use a vice grip on it and make sure u clamp it on hard. Then just give it some taps with the hammer again

My tailshaft-to-diff used Allen bolts.

My tailshaft-to-diff used Allen bolts.

and thats not factory nissan spec... so someone has changed them

[Duncan]

umm no, every tailshaft to diff I've seen in a skyline used allen bolts

[Bl4cK32]

must be a 4wd thing then, as every 2wd ive seen uses bolt/nut setup.

[Duncan]

ahh oki doki I've only looked at gtr

[mr_rbman]

cheers for the suggestions guys, ended up just grinding it off.

The Stagea diff I bought also came with Allen bolts. So could be an AWD thing (mine is GTS4).
