Dyna 1340 Replacing Secondary Drive Belt

Am replacing the belt drive, mine snapped.

Have got to the point where the primary inner casing needs to come off.

Apart from the tabbed nuts/bolts, do I have to remove the starter motor? Does the Jack shaft attached to the starter come out with it?

I have a Clymer manual, but there is no section on replacing the secondary belt. I have no idea why. Also You Tube has nothing I can see on this video wise

Also do I need to remove the swinging arm, or is the removal of one of the rear shox enough.

thanks

Remove outer primary cover, the drive train, the inner primary, the starter pinion/jackshaft, pull the swingarm pivot bolt and isolator blocks, remove the rear tire and drop the shocks, lower the swingarm out of the way. Put the new belt on and assemble in reverse order.
In your Clymer book look in the section on forks, the swingarm is also called the rear fork.

Also replace all accessable gaskets and seals while the primaries are apart. The last thing you're going to want to do is take it all back apart because of a leak.

I thought I might get away without touching the swinging arm, just needing to unbolt the shock absorber at the bottom mount and swing it out of the way.

Yes, you will need to remove the starter motor mount bolts (in addition to the starter jack shaft).

does the jack shaft have to be separated from the starter motor before the starter motor is extracted from the other side?

Yes, the jackshaft must be unbolted and removed from the primary side.

I just did part of this job as a novice so let me add a couple things. When you take the starter jackshaft, be careful not to get things out of order. Pull the whole thing out in a unit, leaving the gears and spring in place on the long screw. There is a large coupling that rides in a bushing in the inner primary. It will probably stay in place when you pull out the jackshaft. That means when you remove the inner primary there is a chance it will fall out and roll across the garage floor (sound like experience talking?) There is a retaining ring inside this coupling and it is very important not to put the coupling in backwards when you replace it. The jackshaft will not work right if you do.

If you like to watch video's, which I find helpful, here is one where a guy does an inner primary seal. It shows the procedure for getting things apart. It is a strange video and the guy does kind of a hack job but you can see how it's done up to the point of removing the inner primary case.


There is also a series by VTwinOnline for stator repair that shows in detail how to get clutch and compensator off. I found it helpful.

Whoa, I didn't expect that giant picture when I pasted the link for the video. I wouldn't beat the seal in with a hammer like this guy did but you get the point watching it.
