Ive been working on replacing my clutch and today I was hoping to remove the last bell housing bolt which is the one thats very hard to get to on the top under a wiring harness . I made the mistake of trying to use a cheap pos Chinese box end wrench and rounded off the bolt a bit . I did some research and found out about rounded bolt removal sockets however most of these are crap chinese junk . I dont want to make it worse so Im looking for suggestions on either a socket set thats good or an alternate method . Any advise is GREATLY appreciated

doing this on jack stands sucks . doing this at 66 with about 2ft of free ground space really really sucks

Try a 3/8's 6 point socket, long extension, long handle ratchet and a swivel. It's not the easiest bolt to get but thats how I deal with it.

 

Appreciate the advice but the problem is the bolt is partially rounded . Seems like all the special bolt removing socket sets skip 15mm for some reason. Bought a special tight fitting set at auto zone . I'll report back tomorrow if they work

 

Also, make sure you hit it with penetrating oil. It can make a huge difference with 24 hour exposure. Also consider trying heat with the SAE recommendation. Pound it on and use a good socket wrench with a breaker bar. Also consider removing everything out of the way. It makes it way easier to remove the bolt.

 

They have hammer on stripped bolt removers . I've had to use them. They bite into the threads to remove it but you will need a new bolt afterwards as it will only remove not out back on due to how the threads are cut

I know that this is a couple of months old but something else to try. If that was the last bolt, put a couple of other easier to access bolts back in and tighten them, not fully torqued but snug. That'll help alleviate any side loading on the stuck fastener and possibly help loosen it.

 

"Sometimes" if the head is rounded off enough, a 6 point SAE socket with go on with a hammer wack or 2. Worked for me in the past. And a big +1 on penetrating oil and patience. BP Blaster is my favorite.
