I can not get it out, Its a 15mm bolt and it is not budging at all. I have split a socket, and my ring spanners just tend to round the bolt head. Im in the process of heating it with a propane torch, then getting my vice grips around them but Im wondering if its going to work.
Has anyone else had this problem, how did you fix it. Can I heat the transmission case??? Its got me totally stumped, Ive never had this much trouble with a bolt.

it's actually a 16mm bolt. i always use a single hex socket and a breaker bar at work. works a treat

You need to hit the head of the plug. As mention before, it was a 16mm hex. They do not need to be done up so tight, they don't hold the auto to the engine block.

I think you were upside down and turned the bolt clockwise and tightening it even further.
 yep, a tap on the bolt and a nice long pipe for leverage.

Nah, I cant get it out, Ive tried and tried, its now beyond my scope, someone is probably gonna have to weld a nut to it or something. Heating it doesnt do anying (with propane anyway) the case must conduct the heat instantly. Maybe I could try rapid cooling?
I think it might be rounded too much anyway now. I was definatly turning it anticlockwise, should I bother trying to do it myself or just get a mechanic to fix this f**k up. Might be time to give in.

I have had to cold-chiesel them out before.....but that was on a hoist.

Well I don't think heating the plug will do much, materials expand when heated, and since it's mounted in cast aluminium, good luck heating all of that. What sort of socket did you split? Get a single hex impact socket on to it, you should be able to hammer it on. |

I cracked a 5/8 hex socket on it, which fit better than the 16mm, never had a bolt so tight it breaks a socket!
Im thinking about getting a can of that instant freeze stuff on the bolt with the transmission hot. Dont know if Im just wasting time and money though. Should I wait for the transmission to fully cool then try??? cjh wrote: I have had to cold-chiesel them out before.....but that was on a hoist. How did you chiesel it out? Just hit into the side of the washer?

Should I wait for the transmission to fully cool then try??? I wouldn't hold my breath with the instant freeze. Tried a single hex impact socket (black oxide finish, not chrome) yet? The strength difference between them and normal socket is huge. |

The bolt head is too rounded now for that, might have to try the chisel. I have never taken one out before, its my understanding there is an O ring underneath the flange? If I cut a majority of the flange off should that release some tension?

i had the same problem on my diff plug in my hilux. tried everything to get it out and i eventually got the welder out and welded some 12mm roundbar to the head of the bolt and used the roundbar to get leverage, combined with the heat on the bolt it came out with ease, once the bolt was cracked i cut the roundbar back with the grinder and unscrewed it.
i used a little inverter stick welder with 2.5 stainless rods(welds easier) hope this helps, |
