While on that subject, my '02 Road Glide book calls for the stepped chain jamming block. What are the cons of using that? Been using it since the first tear down....

This is an excellent time to switch over to a locking bar.  You can make one for free and others for different models so you can fix bikes for your friends.   :hyst:  Seriously though, think about the stress you put on the mainshaft when that chain starts climbing up on the step block and you have a 3" bar trying to crack a shaft nut loose.  How about the pins in that short stretch of chain under the block that does the work?  There is huge mechanical advantage at work causing deflection and bearing strain.  Now put a lock bar between the engine drive and clutch basket and you share the load between both shafts.  I think you can see the advantages.  :wink:

Is it possible to use a locking bar on the -94 to -99 Softail and Dyna primaries?

I made my own one back in 88 for my softy 86, so as long you have a bar with the right length yes!

Yeah, I figured. Been using it all along. Like it better than the bar but OK, I'll make one....  P.S. Already have all the other lengths. I need one a bit longer for the '02...NOPE, don't want to fix anyone else's bikes...LOL!

This may help some I do remember a thread or 2 where the softail length and others were discussed.  Maybe member rbabos? It might show up on a search.

I remember Max doing a load analysis comparison on this.
The locking bar is the way to go.
the last time I worked on the Evo I used two step blocks to spread the load. Next time i will make a bar.

Here you go: https://harleytechtalk.com/htt/index.php/topic,54582.msg575358.html#msg575358

The stepped block can be used for the 5-speed. For the 6-speed the locking bar is mandatory!

Maybe it is easier to use a locking bar on 94-99 Softail and Dyna primaries if using 2001 and up chain tensioner?

If you mean the auto tensioner introduced 2006/2007 you are right! The wedge method puts plenty of load on the tensioner. The manual tensioner has to be lowered completely before using the wedge.

 No, I mean the 2001 L-shaped tensioner as opposed to the 65-00 square O tensioner.

I seem to remember that my selfmade monstrosity of a locking bar, didn't work on the 94-00 Softail and Dyna primaries.
