ironmonkey007 2 Posted June 13, 2025 Hi All, I was at the Tech Day back in Feb with my DR 650 and blown crankshaft bearing. I have decided to attempt a rebuild and am in the process of disassembly. I had wanted to remove the crankshaft ring nut/spanner but it requires a special tool from Suzuki - (09917-23711: Ring nut socket wrench). I wanted to see if anyone in the area had one or had fabricated one and would be willing to help me remove it? If so, I am happy to donate to your Ring nut socket wrench investment fund, lol! FWIW, I don't have the tools to fabricate my own. And I didn't want to cause more damage with a hammer and punch. I'm removing it to be able to replace the bearing. Thanks!

tntmo 1022 Posted June 13, 2025 You should be able to split the cases without removing that, but it will have to come off to replace that bearing. Once the case is out of the way, I would think that almost any sort of spanner wrench would be able to remove it. Something like this? Some of these kind of spanners are available with a square drive to put a torque wrench on them so you could reinstall it and get the proper specification on it. Otherwise we have some pretty good fabricators in this group, you could see if someone could make something for you since you said you are lacking in tools to make it yourself. I think starting with a piece of pipe with the same diameter of the ring and then filing/grinding/milling out the "teeth" would be what I would do. I'm glad to see that you're moving forward with this project and taking on the challenge. 1 Share this post Link to post Share on other sites
DSM8 465 Posted June 13, 2025 I have a version of those wrenches you use with a ratchet; they will be back at the house tomorrow. PM me for details. Share this post Link to post Share on other sites
ironmonkey007 2 Posted June 13, 2025 @tntmo Yeah, I was concerned that once the crankshaft was out of the case it would be difficult to get that ringnut off/on (torque = 80 ft/lbs). So I was trying to be proactive (and follow the manual :)). But I may just move forward with the case splitting and deal with the outcome. I wouldn't be reusing the crankshaft as is, it will get rebuilt or replaced. And thanks! It's been quite an experience so far. I've learned a lot. @DSM8 Once I get the cases split I will assess the situation and may hit you up. Thanks for the offer! 1 Share this post Link to post Share on other sites
tubebender 64 Posted June 14, 2025 I had to make one before for an auto project. The factory tool was $800! Crude, but it worked. If all else fails, let me know and we'll get it sorted. 4 Share this post Link to post Share on other sites
DSM8 465 Posted June 16, 2025 I want to watch! Thought of this solution as well would be easy enough to make but I have the gland nut wrenches which are made for basically the same thing. Yours might be a better solution since mine uses a round peg in a square slot. Share this post Link to post Share on other sites
