nzhaystack 0 Report post Posted February 28, 2011 Hey Guys, Over the last couple days my gearbox has been in the process of been removed, we are 95% there with only 1 bolt still attaching the gearbox to the engine. The Inverse Torx Sockets i used for the bolt were either too big or to small and after many failed attemps the head of the nut has completly worn down beyond recognition. The bolt is slightly above the slave cyl which has been removed for easy access. Still though, i cant get a file, vice grips, or any sort of device into there (apart from a socket). Does anyone has any suggestions on how to remove it? It has a tonne of crc on it and still wont budge, the gearbox is also back in its original place with the help of some jacks, so there is no real strain on it. Any help on this one would be much appreciated Cheers Mitch Quote Share this post Link to post Share on other sites
flake 0 Report post Posted February 28, 2011 use a grinder and cut the bolt head off, dont be shy. had it happen to me when not using the correct torx sockets. but this was with the engine/gearbox out of the car. good luck Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted February 28, 2011 As above Use a grinder (if you can access) otherwise a die grinder or gas to remove the head Quote Share this post Link to post Share on other sites

polley 916 Report post Posted February 28, 2011 If you dont have the room to use a grinder, gas, or die grinder, put some extra bolts in the gearbox and remove the whole engine with the gearbox. It's not that much work. Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2132 Report post Posted February 28, 2011 did suggest this. i think it took me about an hour or so from having the car driveable to engine and gearbox on the floor, including trying to remove it witha forklift lol. could be an option mitch if you have acess to a hoist. As long as your car is gone from my drive at some point lol Quote Share this post Link to post Share on other sites
BM WORLD 1283 Report post Posted February 28, 2011 lift the engine off its mounts and move it forward/side ways etc . should give you enough room to get a grinder in there. Quote Share this post Link to post Share on other sites

Cheers guys, since there is only one bolt holding it in which looks like to be an Inverse Torx - size 13. I will buy a set of sockets and get it out for good. Otherwise i will look at the engine removal option Quote Share this post Link to post Share on other sites
Phatputer 3 Report post Posted March 1, 2011 Powerbuilt do a full set of both torx and invers torx for about $60 - $70 Ended up having to get both while pulling apart and reassembling my e30's Quote Share this post Link to post Share on other sites
tcbaurpower 5 Report post Posted March 5, 2011 How did you go mitch? In the past if a bolt is refusing to move and then gets to rounded for that sized socket I would hammer on a smaller sized socket. Works every time. Note however the hammered socket can be ruined with this process. Quote Share this post Link to post Share on other sites
