Canon BG-E2N battery grip stuck on 50D body, how I got it off and fixed....

Recently while using a BG-E2N battery grip on a 50D I had a problem removing it, the wheel would turn but the grip would not budge....
It would seem that over time I had been over tightening the dial lock and had manage to strip the plastic gears from it.
I did a search on the net and found it to be a common problem with canon grips, although information on getting the grip off was not so common.....

The following is break down of how I got it off and repaired for minimal costs.

From what information I could find on the net it would seem that making a hole in the locking wheel was the best/ least destructive way of getting the grip off.
I used a miniature pair of wire cutters and made a small hole in the wheel which exposed the metal gears inside the grip.





At first I tried to use a small screw driver to turn the gears within the grip but could not get the gearing to turn, a closer look revealed that some of the plastic gears teeth had gotten stuck within the metal gears.
Once I had cleaned out the gears with a needle I was able to turn the gears and remove the grip easily with a small screw driver.





Now that the grip was off I could relax.... a little, I still needed to see the what was damaged and if it could be repaired.
The first thing that needed to be removed was a cover plate at the top of the grip which was held on by 5 short screws and 4 long screws.



Once the cover plate was removed the Dial assembly was exposed (part # CY1-4313-000)



There are 8 screws holding dial assembly to the grip, 5 which screw into brass and 3 of which have slightly thicker threads as they screw into plastic.





With the dial assembly unscrewed I was able to access the plastic wheel by removing a small plate that held it in place.



In the ideal world I would have been able to purchase just the plastic dial but Canon only sale the whole dial assembly.....
Searched the net and the only place I could find that sold the part was www.uscamera.com/index.htm
Ordered the part (# CY1-4313-000) for $36.13 USD which converted to £22.64 GBP. It was delivered within 2 weeks, great service from USCamera.com!







I was planning on removing the dial from the new assembly and fitting it to the old assembly to save time, but I noticed that when I had used a screwdriver to remove the grip I had made some small but noticeable scratches on the original gearing that might damage the new dial.
I decided to fit the whole new assembly just in case, which unfortunately meant that I would have un-solder/ re-solder the power cables that pass through a hole in the dial assembly. There is also a small ribbon cable that passed through it but could be unplugged.



Had to be very careful when using the soldering iron on the power cables as the was little play with the cables and there was a ribbon cable close by.......

Once the soldering was done it was just a case of reassembling the grip and attaching it to my camera for testing, although I didn’t tighten the dial too much this time....


The Canon grip is a well made piece of kit it just a shame that the silly plastic dial lets it down....

If I had to do it again I would make sure I used some tape over the end of the screw driver or used a wooden matchstick to turn the gears, this would have prevented the damage to the gears and would have save the cable soldering, oh well you live and learn......

Well done. several people have resorted to sawing through between base of camera and grip! Your method is excellent and good to know.

I just recently had this happen to mine. Very nice tutorial and thanks for the link on replacement part. You just saved me a piece of equipment.

Terrible design flaw - why they don't make the thumbscrew out of metal I'll never know. It would probably add only a few pence to the cost.

I always wondered what you guys were learning in shop class while I was in band practice. Now I know, and it is a hell of a lot more useful than knowing how to play the trombone or march a sousaphone around the field at half time.

I wonder if you can not order a custom dial wheel made from metal? Not to canon but to another shop like the hardware shops.

There's probably a good reason why not every part of a camera or accessory is made of military grade metal. Some pieces are designed to break under stress, to save other parts from breaking. It's like the crumple zone of a car protecting you (inside or outside a car)

For instance a flash foot is made of plastic to prevent the flash from ripping the hotshoe off the camera when you bump into something. The plastic gears in the grip are there to prevent the tripod mount of the camera body from being torn out.

Dear Knucklehead says:

Victor - the problem here is that the screw that holds the grip to the camera is metal and the part that you use to tighten the screw is plastic. What purpose in making the operable part weaker than the part it is designed to hold against?

This sounds like a problem that Canon knows about but doesn't want to fix (perhaps they made a run of a billion of these things without proper testing and rather than just doing a silent upgrade and swapping parts out they'd have to scrap the entire production run).

Would you rather have a plastic screw holding the body and grip together?

Love the details you put in the descriptions. Especially color coding the screws.

Best thing for Canon would have been a metal gearwheel with Plastic/Rubber outer surface, so you can easily grip it. That way if you are trying to over-tight the outer surface can turn freely. In worst case you can just cut away the outer surface (like a gasket) and takeout the stuck grip.

victor - why not just make the whole thing metal?

Salt Photography says:

Victor - valid points made, however in this case, if the plastic component was made to give way to protect the camera body, then what if you connected the camera directly to a tripod with no grip? If the threading inside the camera was so weak (given many base plates for tripods are 'military grade metal' anyway), then the camera would become damaged anyway. Surely, if a 'give' part needed to be employed here, it would be in the camera, not in the grip. No, I think Canon are being cheap... for those based in London, Sendean cameras offer a repair service on this. Not cheap at £139 (plus VAT), but one of the benefits is that they replace the wheel in the process with a proper metal one to prevent it ever happening again. I have no idea where they source this from though if you were to make the fix yourselves...

I'm sure with both gears being metal even more over tightening would occur, and possibly strip the smaller gears teeth off, making removal even more difficult.

There is just no excuse for this. Plenty of items are made that need to be tightened down, over and over again, without being stripped....and are a lot cheaper than this grip.

strobane says:

Thanks a lot. I used the method to get my BG-E4 of my 5D. Unfortunately the metal gear got damaged during the process, because it was tightened VERY hard. I had to use a screwdriver, and a small hammer, to get it of.
But, at least I got it of, and can probably get a second hand replacement cheap.

Thanks again!

In reply to 'Salt Photography' above: At that price you may as well get a new one - I have 'Hahnel' grips on both of my DSLR's and have never had a problem. :o)

@Luxescene says:

he just told you his theory on why both parts aren't metal. You need something outside of the camera itself to be the weak link if something breaks. better to replace a $50 grip assembly because the plastic dial broke than a $600 camera because the metal mount housing broke.

mark_flower_photography says:

Thank you so much for this post. I followed your instructions to the letter and fixed it with no damage to the body or grip except the part that was going to be replaced anyway!!

Saved me a ton of time and stress. No i'll have to do my other one with the new metal cogs before that one goes!

Thanks again.

Thanks for posting this in detail. It took a little over 5 minutes to get the grip off by following your instructions. I used a drill to break into the plastic dial and taped everything off to make sure I didn't add any scratches.

I found this ebay item: item.ebay.com/330758288246/
It seems to be a metal gear screwed to a plastic dail.
Anyone seen/used/tried this?

This happened to my 5D MkII battery grip, would these instructions work for the BG-E6 as well? I think that all the Canon battery grips are alike but I am not sure.

Thanks for the information. I will never buy that battery grip. Still dont understand why plastic wheel? It is not Chinese toy, common Canon if one can spend 100$ for a grip he does not mind paying extra 0.5-1$ for a small metal wheel. We don't expect 'Golden Wheel'.

Hey, Gutje, bought the plastic with metal gear wheel you're talking about. It surely fits the BG-E2N. My grip has been reborn!
