Once you do it, you will have so much confidence......
Now anybody know how to put a swing arm back on?
Did my T-Bird's one recently when changing the chain & sprocks (chain was continuous).
The T-Bird's one I would say is particularly tricky. Reason being all the different parts of the frame (and the swing arm itself of course) which the spindle has to pass through. There was a shim on the rhs too which can easily pop out just as you're lining the darned thing up!
The most difficult bit was the central spacer!! It's nigh impossible to reach on the T-Bird and needs to be perfectly lined up to get the spindle through.
OK, make sure you've got some nice molybdenum grease (that's the blue stuff), clean everything up good and grease all your swinging arm bearings etc. I used some to "stick" the rhs shim in place whilst re-assembling.
Measure the diameter of the spindle. It'll probably be 20mm or thereabouts. Pop down to Homebase or wherever and get a length of dowling the same diameter (I actually went for 2mm less diameter, reason being that I needed to make a drift out of it to remove the spindle in the first place using a 3lb lump hammer; I increased the diameter of the dowling by wrapping it in parcel tape to prevent it splitting whilst I was beating ten bells out of it). Wood makes for a pretty safe drift when used against metal.
Lay something on the ground under the rear of the bike to rest the swingarm on, to prevent it getting scratches/dirt etc. from the ground (I used an old sheet).
Have a few "baggage ties" to hand. Not sure what they are called properly - they're nylon straps with a "croccodile clip" at one end that you can use to e.g. fasten down stuff to your luggage rack (sold at e.g. camping shops).
I used 2x ties to hold the rear part of the swingarm up in the air (attached to the upper part of the rear sub-frame), i.e. to take the weight and help align the swingarm (keeps it off the ground too). Line the swingarm up with the holes in the frame (this will likely be a very tight fit and drive you a bit mad). If the spindle needs to go in from the lhs of the bike (like the TBird), use the dowling to position the rhs first (i.e. insert it as a "spindle" from that side). That'll hold the rhs while you fit the spindle in from the left. Grease the spindle, and insert, you may need to gently drift it in, use a piece of the dowling for this purpose. (If I remember correctly, I used the dowling to locate and hold the central spacer too).
On the TBird, I hit a problem at this point as although everything looked lined up, the spindle was catching the frame slightly as it came out the lhs of the spindle (it wouldn't pass), so I used a further two baggage ties around the spindle-end of the swingarm and the frame above to crank the swingarm up the fraction required.
Continue drifting through, the spindle will displace the dowling until it passes all the way through. Carefully check the movement of the swingarm. Torque-tighten the spindle end-nut and carefully check the movement of the swingarm again.
Re-connect the rear shock linkage, brake torque lever (if fitted - it'll almost certainly need a new torque nut if displaced), rear wheel, adjust chain, chain guard etc. and go!
(Aside: Oh, very important point - make sure that the chain is passing correctly over the swing arm before starting to line it up and adding the spindle etc!)
HTH!
