I have a '93 Heritage Softail Classic and am currently in tear down to replace the inner primary bearing. Clutch, chain, comp, stator/rotor and starter jackshaft are all out.

My manual says to remove the starter next which first requires you to remove the starter jackshaft assembly. With that removed, it appears the primary is clear. Is there some reason I am not seeing that the starter needs to come off other than the manual say to do it?

Anybody have any reccomendations on "to do's" while the primary is off? 51,000 on the bike, 7,000 on a factory rebuilt motor.

 

You need to at least remove the starter bolts on the backside of the inner primary.

 

Yep thats all. Can just leave it in there.

 

Are you thinking of changing your primary ratio while your in there?

 

Please expand on changing the ratio. I bought an older bike as I love to wrench. This is my first Harley though and any advice is very welcome.

 

Depends if your happy with your bikes power on the bottom end. Changing your primary ratio will make your bikes get up and go come on faster but on the top end the rpm's will be higher. Some bikes are sluggish on the bottom end and people will change the ratio to get the power faster. A cam will do this for you too. Post a question in the evo section as I am not familiar with exact details on primary ratio. You can also achieve this with a drive sprocket change.

Copy that. When I bought the bike, I changed the cam and worked the carb. Had Vance and Hines pipes already. Increased my power dramatically. Am pretty happy. Just want the noise from the primary to stop.While I am in there I am in there, am gonna replace the comp and clutch hub bearing.

 

Another thing to look into is the Hyden M6 primary chain adjuster. http://www.vabiker.net/2008/11/insta...ain-tensioner/

Finished the primary. Talked to a local Indy and explained the symptoms. He said it was most likely not the inner primary but the compensator or clutch hub bearing. Pulled the clutch apart and the bearing is fine. Put a new comp in, buttoned it up and the rattling noise is gone. Finally. It shifts smooth, is responsive and I can actually hear the rest of the bike. Of course I can hear an exhaust leak in the front now. Gonna pull the pipes on Monday and put new exhaust seals. Luckily I have some. I think the bike is where I want it to be now. Since I bought it 2 years ago, put in an EV27 cam, adjustable pushrods, timken bearing, new primary chain, m6 adjuster, bigger jets in the carb and drilled out the vacuum port on the slide, brakes, a seat, tires and a lot of sweat. Now to enjoy the riding part..... Thanks for the help guys.....

 

I have a question. When putting the jackshaft back together how far do i push the gear piece back in. I have a bit of tesion from the spring and how tight should the bolt be.
