Transmission case removal

Hi,
Wondering how to get the metal transmission case off?
(Case that protects drive belt, variator etc)
Tried moving the nuts but there not shoving at all, any suggestions?

 

... I've got alot of good metric tools, the nuts are extremely tight wont move at all, I know exactly what to do after getting the case off, just wondering if anyone had any tips such as abit of WD40, or a special way to remove it instead of sarcasm, as it doesn't help at all.

 

heat gun/impact wrench and wd40 if theyre really stiff mate.

 

Cheers mate, yeah there tight, wouldn't be surprised if someone wielded the things in really not budging at all

 

might be loctited in

get a breaker bar and twat it with a hammer, might wanna put a bit of a rubber glove in the socket so it dont round the bolt

 

i had similar problems whatever you do dont get fucked off with it and try prying the cases of will cost ya make sure ur using the right socket and try not to round them

 

it's corrosion mate, the steel bolt reacts with the alloy cases and seizes in the threadds solid.

get a heat gun and get the case as hot as you can, then using a good 8mm socket or 5mm allen key (depending on what kind of bolts you have) try unwinding them, the trick is not to use excessive force as they do shear off quite easily, then its a case of drilling and tapping the remains out. a good soaking in WD40 for 24 hours will help too.

 

Cheers wobbly mate, yeah ive used about half a can of the WD40 and managed to get out two, rest aren't coming out - i'll try the heat way tomorrow unless it rains

 

Lol use a single hex socket aswell that way it ensures you ahve a good tight hold, multi hex are good but not for tight things they have a tendancy to round. Same with spanners.

 

yeah a 6 sided is a MUST the 12's are crap and eat the head of the bolt.

well thought of.

 

Heatguns are abit to heavy though, probably use a hairdryer and I don't mean it weight, I don't want a load of black marks and dripping paint over my casing lol

EDIT: and yeah there the 8mm bolts

 

i always use a heat gun, get the metal quite hot and it burns the corrosion out of the threads. shouldn't get dripping piant unless your transmission case is painted.

 

alright then, as they break glass and burn wood easily

 

just thought, some have a plastic case on the outside, that may melt.

 

Nah, it's nice and sturdy metal - Would hate for it to be plastic lol

 

Just don't snap all the bolts off in there! try with wd40 and leave it and then try again could also try with a small blow touch

 

i've had this with a few, got one at the moment, its not an old motor, original bolts, just corroded in. i know that most arent going to survive, just means using good molies and wd40/heat when they do break off. or at worst drilling and helicoiling.

 

angle grind the nuts heads and then drill dem out.
