I've actually never used the toolkit for this - so far I've always done it in my garage where I've got more and better tools available. But I thought the adjuster and the locknut were different sizes specifically for this purpose. So one spanner (the 10mm?) works on the adjuster while the other (the 12mm?) works on the locknut. Then again, I could be totally mistaken.except you need one to hold the adjuster while you use another to tighten the locknut....
The two ring spanners are both for the rear axle. One side is 24mm, one side is 22mm. My 2015 DL650 is the same way. Just like how the lowering link rods have 14mm on one end and 17mm on the other. Theoretically so you dont need duplicate wrenches to loosen and tighten? One of each will do it. The sick irony is, both of those ends are on the same wrench in the kit so you cant back it with a second tool. Doh. My tools look pretty much like yours btw. Just checked.I have no idea what I would use the 22mm ring spanner.
Actually the '02 DL1000 is different. The axle sits in the adjustment block on the left, and doesn't need a spanner or anything. It's just the nut that you need to undo (right hand side, 24mm). But I see the DL650 has a different chain slack adjustment mechanism. It could well be that Suzuki wanted one toolkit that works for all bikes, hence the 22mm.The two ring spanners are both for the rear axle. One side is 24mm, one side is 22mm. My 2015 DL650 is the same way.
I know and it makes a great addition to the toolkit but it's a bit costly if you've got nothing else to order from them anymore, and need to pay for international P&P... I got one of those multi-adapters from AliExpress instead. (11.99US $ |Universal Aluminum Hex Axle Tool 4 in 1 Motorcycle Front wheel 17mm 19mm 22mm 24mm Allen Wrench Tool Adapter|tool tool|tool in 1tools 1/4 - AliExpress) Disadvantage is that it sticks out quite a bit so it's hard to put proper torque on it. And in the garage I have the appropriate hex socket that fits my 1/2" breaker bar. BGS 5184-H19 | bitinzet | 12,5 mm (1/2") | binnenzeskant 19 mm: Amazon.nlAdventure tech sells hex nobs for front axle use. Changes a fat allen to something you can use a hex wrench on. I'm planning on getting one when I get serious about making an upgraded tool set for my bike.
