Bike Model = : GT250R
Hi guys. Today i bought a good, used swingarm to replace my old one. Has anyone removed a Hyosung Swingarm?
What method did you use? Any problems removing it? Need special tools to remove swingarm shaft?
Any tips you can think of, would be great.

Yes done it many times.
1. remove exhaust trust me.
2. Get a Cruiser Floor Lift thing (this life cruiser bikes) , so this lift will sit on your frame bars under the engine and lift the bike.
3. Once lifted, get breaker bars and torque wrenches and service manual because you need the torque numbers for specific bolts when tightening things back
4. Pivot = 17mm both sides.
5. Rear axle = 22mm & 23mm sockets
6. Bottom linkage = Get between 17mm to 27mm sockets because one nut is bigger than the other.
=== Swap swingarm 😉 but i know it sounds simpler than it looks but take your time , the key impotant thing is to get a bike lift to hold the bike in the air safely!!!
This lift also helps do maintenance like fork changes , shock changes , or wheel changes.

Cool, Marcel, i’m glad you’ve done it. I have a scissor lift & a wheel stand – i just did my front forks. Happy to take exhaust off.
-The 17mm PIVOT will a normal socket fit? Or do they have to be really thin walled to fit on the nut?
– Do i need a 17mm socket on both sides of bike? One to loosen nut & one to hold?
– Did you use SOCKETS or RING-SPANNERS for the SHOCK LINKAGES? Not sure if i can get a socket in there?
– I thought i may be able to leave most of the SHOCK connected to the frame. And just undo the linkage & bolts that connect SHOCK to SWINGARM. Is that what you do? Or did you remove the shock from the frame too?

Use 17mm deep sockets for the pivots as it is a deep hole on each side. Yes one to loosen and one to hold.
As for the shock, the shock stays in the frame, the swing arm is just locked by the “Y” bone linkage that’s all.
If you don’t have a chain fitted yet , you can fit sockets on each side of the Y linkage , but be ready to use a strong O-Spanner (don’t use “12 sided” O spanners as they will round off the nuts!)
Also use 6-sided sockets for everything on the bike , 12-sided sockets have always been bad on bikes as some stubborn bolts get rounded off quickly , but a six-sided spanner/socket makes things easier.

Sweet, thank you very much, Marcel. Gad you’ve done it. Was anxious but i looked at it this morning. The LEFT 17mm is the Pivot SHAFT & i can get it with a normal socket. The Pivot NUT on the right does need a DEEP SOCKET. It looks like 18mm but if you say 17mm, i believe you. 😆 My chain is OFF; the old one was rusted, stretched & dangerous – it’s in the bin. The new one is cut & ready to roll. I got a newer rear wheel & new tryes to go on. Found a good swingarm before i put the chain/wheel on. Wasn’t looking, just got lucky. It’s pretty rust free but i cleaned & anti rusted it, at the joins & inside mostly.
I am stoked the shock can stay mounted to the frame – i just put that on there, i don’t want to touch it. I’ll get that bottom bolt out of swingarm/shock by removing the footpegs, to make more room. Is that what you do?
Can you recall what is inside the SWINGARM, between the BEARINGS? This new swingarm has ONLY ONE spacer (about 6 inches long) . But the manual has one small SPACER & one SEAL, (Rear Chushion Rod SEAL). The seal looks like another spacer. Hyosung don’t seem to sell the SEAL & i don’t have it in the new swingarm. Looks important. Any ideas where to get one? I’d rather not use the old one.

8. 09284H32001 SEAL, rear cushion rod

Removing the rear pegs does help yes indeed.
Also the swingarm bearings inside have 2 big spacers left & right with a metal-rubber seal closing both ends. It is OK to use the old caps (rubber metal seals) as all you need is a very good high mileage bike greaase (or high temp bike grease works OK too) , they tend to keep some moisture away. Chain will will spin and keep the left side dripping with a bit of grease escaping the chain, so that left side of the swingarm won’t be as dry to be a concern yet.
