I’ve spent a lot of time looking for long 6 point box end offset wrenches. Does anyone have a set that can tell me the brand?

I rounded off a 17mm differential filler screw, located where shallow and stubby sockets can’t be used, with a Snap-On 12 point box wrench. Tried a 17mm Craftsman line wrench and it just ruined the wrench. Argh.

I think Gear Wrench makes a 6 point combination wrench available at home depot.
Or you may want to look at Facom PG.76 Socket Spanners Amazon.com

Whoops my mistake the Facom PG.75 is 6 point on both ends.

Thanks for the info.

I’m guessing this fill screw is torqued to 80 ft lbs or more, not sure a ratcheting wrench would hold up.

The Facom are cool but, in this case, too tall.

The fill screw is half way hidden behind the rear subframe. There’s less than 1/2” clearance to slide a wrench in to engage the head. Stupid design. I wish I had one of those inductive bolt heaters to try breaking it loose. I may end removing the diff just to get the fill screw off. Ugh.

sounds like a 17mm Allen wrench used on Air Cooled VW may do the trick. If the plug is that tight you’ll need a cheater pipe and a car lift, although you maybe able to pull it off with Jack Stands. You may consider removing the panhard rod for work space if it is in the way. I hope this is of some help.

Not sure if something like this might help, but I’ve used them with a socket and a ratcheting wrench in similar situations where a conventional ratchet wouldn’t fit. You could use a 6-pt socket and a regular non-offset wrench. Maybe you could grind down the socket etc if necessary for extra clearance?

Best of luck!

The fill hole is plugged by a flange bolt like this, not an allen screw.

Unfortunately there is not enough clearance above the bolt head for a socket, even a stubby socket. It has to be a wrench that can slip in the gap between the bolt head and the rear subframe above it. Hopefully the bolt threads are short enough to get it out. Should be, it’s just a plug.

I found a set of Capri brand 6 point box end wrenches on Amazon that should be here by 10 pm tomorrow. Can’t wait to try them.

The bolt is so tight I’m worried that the wrench will break, or the bolt head will be destroyed or the aluminum differential cover will bust open.

A 6" pipe wrench and cheater pipe will get it, if there is enough of the head left to get a bite on.

Great idea. I’ve tried big crescent wrenches and large Knipex pliers, neither of which can get a bite on the bolt head due to cast aluminum fins surrounding the bolt head. A small pipe wrench may have enough clearance. If all else fails I’ll grind down some fins and make clearance for beefier tools. I may even grind the interfering subframe to give me clearance for a 6 point impact socket.

You may have to resort to a fire wrench to loosen it.

Mac used to make 6 point box wrenches. I have one in 12mm.

If you get a wrench that fits tight, hold it securely and tap the end with a hammer. Not too hard, and go in both directions to work it back and forth. Once it moves spray more PB Blaster on it...I say 'more' because I know you already sprayed some on, right?

 

[okieopel]

maybe a HAZET 2760 or Capri Oil Drain Wrench would do the trick. Ya ya, that's the ticket.

 

[kwschumm]

Thanks guys. Yes, I used lots of PB blaster and tried to tighten it first. I also tried using a MAP torch which didn’t help. Also a blunt bit in an air chisel to try to break the bond.

I was going to take it in anyway to have the coolant changed (it’s very hard to recycle coolant around here). As an AAA member they put it on a flatbed and took it and me to the shop for free. I brought lots of donuts to share. They changed the coolant and had a long six point box wrench to break the bolt and filled the diff oil with the oil I brought. Total damage, $110. Nice guys!

I did find six point offset box wrenches at both Snap-On and Mac tools. Around $750/set or $45 a wrench. Donuts are cheaper.

Thanks for all the ideas! Much appreciated.

When does my donut arrive?....

OK Mr Schumm... So you're not working on an Opel... sounds more like a BMW...? I have a set of Craftsman Metric 6-point box wrenches. Brand new in the box- I keep them in my racecar trailer, just so I don't need them..! Not sure how long "long" is, but if you need the part numbers, I can get you that... Let me know...! Ernie

 

[kwschumm]

Hi Ernie, It’s a Subaru Baja. By long I’d say at least a foot. I didn’t see any six pointers on the Craftsman site but I could have missed them. I’d like to have a set so I won’t need them too!
