R33 Gearbox Oil Change

[Roffy92]

hey,

so as the topic states i have rounded the filler plug on my gearbox whilst trying to get the lil bastard out.

just wondering if anyone has any ideas as to what i do now?

i read on an old DIY that you can refill the oil through a hole or something near the gear shifter inside the car?

iv had a look and cant see any obvious way of doing this, if anyone has done this successfully where am i ment to be pouring the oil?

thanks for any help...

hey i just changed my gearbox oil yesterday. tried to take out the gearstick but couldn't. then had to refill at the bottom. does anyone have a step by step tutorial on how to remove gearstick? i heard you need a right angled long plier to remove the stick?

ahh, so you take the shifter right out do you?,

theres a step by step how to in the DIY forums under installing a short shifter or something like that

ill give it a crack, hopefully my drain plug doesn't round aswell..

on that note my 1/2" drive breaker bar doesn't seem to fit snug in these plugs, any ideas on how to prevent it from rounding them?

Remove the two circlips and it will come off. 1/2 inch works for me, they shouldnt be that tight that it rounds it, just be careful when doing it and if you feel it slip stop.

alright got the shifter out no worries, then got back under to remove the dump plug and..... no bingo!

i'm using a 40cm breaker bar WITH half of my garage jack handel on the end giving me a total of around 1.2m worth of breaking power, iv sprayed the crap out of it with Lanox inox

and still just feels like its bending the plug about to round it!!!

any ideas what to do?

I've got them out a few times by using a hammer & cold chisel. Bite into the side of the plug with the chisel and rotate it using a series of blows to break it loose.

Not ideal, but works..get a replacement plug first.

Heat it up a little with a propane torch just make sure u clear all the wiring. That will definately losen it up dont even have to get it really hot.

take it to local mechanic. pay $5 - $10. ask them to impact wrench it off. easiest way. your killing yourself.

This seems a common problem with skylines, why are so many of the plugs "welded" on to the point a breaker bar just rounds them?

[boostn0199]

Because theve prob never been opened before.

Hmm maybe, mine definitely looked to have some sort of loctite on it :S

[Roffy92]

the only issue with taking it to a mehchanic is once they get it out they will have to refill it so i cant get it home.

dont wanna know what they will charge me for a few hours labour and use of their shop.. :S

waiting on a new plug now so i can try the chisel... if that still doesnt work for some reason then ill have to take it to a mechanic haha

I had the same problem with my motorbike's sump plug, I tried everything but managed to get it using vice grips + hammer.. had part was getting those vice grips on super tight.

In trying everything, if the vice grips didn't work I was willing to sacrifice a ring spanner by welding it to the sump plug

Did mine yesterday and was tight but with a standard braker it got undone, was not worried about rounding it at all, there was alot of some form of sealant on the plug for sure, as it's only a shallow 1/2 inch plug just make sure the bar is in good and proper and let the guns do the rest of the work
