God... I just tried with a pair of vice grips to get that thing off for so long! I also tried hammering on a damaged bolt socket... I can not make this thing budge. Anyone have any helpful hints on how to remove this? I have a nice 17mm replacement ready to go but can not get the 12mm off for the life of me!

(I did use the search function)
Thanks!

Use a cheater bar/ hollow pipe to slide over the end of you socket wrench (leverage).

i ended up having to cut the end of the bolt off (destroying the filter housing in the process)

+1 on the hollow pipe over the end of your wretch, leverage is your friend.

I used an angle grinder with a cutting disk to cut a new hex on the end. I was careful to not cut into the housing. When I was done the housing slid off the bolt and the bolt came out rather easily. I had a new 17 mm bolt and filter ready.

It sounds like he has a 12mm pounded on already? just put the socket wrench on and use a cheater it will come off if you have a long enough cheater but it sounds like the bolts will be toast ( get a new one)

I welded a bigger nut on the end of the bolt to get it off, in hindsight cutting ir off and ordering a new one would have been less hassle

good luck

A cheater bar could have avoided this thread

Never ever use a 12 point socket on this bolt! IF you do not have a 6 point, buy one!

It never ceases to amaze me that people tend to overtighten these things in the first place. It doesn't require alot of tightening to squish the o-ring seals to do a good job, and only enough tension on the filter bolt to keep the housing from vibrating loose is all that's needed. The o-rings do the sealing, and once the housing makes contact with the engine block, it's not going to seal any better with more torque on the bolt! Take it easy on the new bolt too.

This is the first time changing the oil since I bought the bike. I had nothing to do with the over tightening. I already stripped the hell out of the bolt... I have a 17mm replacement in hand. Any other crazy tricks - I wish I had access to some power tools!

Sorry about that, I wasn't implying that you overtightened it. I had an 81 or 82 CB650C that I bought brand new, and after I went to do the very first oil change after the dealer had done the 600 mile check, I ended up having to take the bike back to the dealer to have THEM remove the filter bolt. I had to tell them to take it easy too. Even they ended up destroying the bolt to remove it too! Served them right!

FWIW, my Sanglas bike -yamaha xs400 engine- has a similar oil filter setup than the CB750. The Yamaha engine, being 10 years younger, has some cool things like showing the torque for the oil bolt on the oil filter housing.

Can't remember now how much it was, but just let me tell you that my torque wrench -the big one- had a higher torque even in the lowest setting. I had to use the small one -1/2 fitting- to torque the oil bolt. I could have never imagined how little it was. Something like when it is starting to tighten, then "click". If you use a regular spanner, you have to stop tightening real quick. ¿Have you heard about spark plugs tightening by hand and then just 1/4 turn more? This is even less.

So, for next time on my CB750, I will use the same rule. I didn't tighten it much, but definitely more than the XS400 specs.

Ya just gotta love those OEM filter canisters............ NOT!!!!

Quick question before you destroy the front of your motor, which way are you trying to undo the bolt?
It's standard thread so needs to be cranked to the left if you are facing the motor from the forks.
I'd use what we call a stilson here in NZ, you guys probably call it a pipe wrench, the kind that adjust tighter the more pressure you put on it.
+1 On the cheater bar (love your coloqualisms)

eg big fat thick pipe that slides over handle of wrench to give huge amount of tourque.
Worst case scenario, drill into the head of the nut and screw in a self tapper then use the wrench, the screw will give it something to grab on.

I'd second that on my bike. Some PO had used vise grips or sommething to try to turn the bolt. I tried vise grips myself but couldn't get a good grip. I found out what "PO" really means.

Try using Vise-grips with GOOD SHARP teeth..

My first oil change on my 750......

I resorted to power tools in the end.

A little extreme?

I just dremeled the head of and pulled the housing off over then put vise grips on the bolt. No damage to the filter housing. Replaced it with one of the 17mm ones.

Yeah, well thats what people that arent power tool freaks (and have patience) do.

Then you can ride the bike..not wait for parts..

And make sure the vise grips are not flat head, but curved. You can get real good grip with those with the curve in them. If you have to file or grind a couple flat spots on the side of the bolt for the vise grips to bite on.

Well of course, "Down under" to Canada is America Frank, but if you're talking about me, I'd much rather be an Aussie Gnome, than a Canuk Troll, ha ha!
