Change out all primary drive seals and gaskets on '06 Road King
Looking for tips when changing out all primary seals and gaskets on '06 Road King Custom. Had an '90 Softail Custom with jack shaft leak. Removed the primary case and change all seals/gaskets without the expensive HD tools that are recomended. Used impact to tighten engine sproket and jamed a soft, plastic handle screw driver in the drive to keep it from turning under torque. The soft plastic screw driver did not score or damage anything. I plan on doing the same with the '06. The primary is very similar to the '90 so I'm figuring it should work. Any helpful tips or suggestions I need to watch for with the '06 is appreciated. Thanx.
Re: Change out all primary drive seals and gaskets on '06...
Sounds good if using a impact u dont need to put any thing in the primary chain the motors compresion will be enough presure, make shure to put the seals in the right way, depending on manufacture some seem to be backward.

this is a pretty big job, the whole primary needs to come off, clutches, compensating sprocket, and inner primary. you need to unbolt the swingarm, remove the left side isolator, unbolt left shock, carefull sneak the belt between the trans housing and swingarm. If you wanna tackle this yourself. your are gonna need a manual, there are alot of specs to follow. you really need to look closely at the 3 transmission seals, any wetness, i would change them, i usually change them all anyway. you need to change the inner primary seal and starter shaft seal while you're in there.
to change the final drive belt on your Road King, you must pull the entire primary off. The outer primary cover, the clutch and primary chain, the inner primary, and the starter must come off. Then, you have to remove the rear wheel, remove the shocks, and pull the swing arm out as well. It's a major job.
All old harleys leaked oil, so its no big deal. First try tightening all bolts to primary cover, they should be allen head, so you will need a allen wrench of correct size. To change gasket you will first need to remove floorboard to primary bolts, then all the allen bolts. Put a pan under to catch oil. scrape old gasket off and install new gasket with a small bit of rtv to hold it in place. Put everything back together.
Base gaskets leaks, rocker box gasket leaks.
Final drive belt wear
Final drive belt sprocket wear
Loose/worn steering head bearings
Check spokes if wheels have them
Check under seat for damage to frame/surrounding area from leaky battery
Check all turn signals/horn/brake lights, high/low beam, tires
Test drive bike
Check VIN for modification
Check VIN with local police to make sure not stolen
Make sure title is clear and transferable
Spray it off at the car wash to remove all the oil , then spray Right Guard (Yes, that Right Guard) on the area of the leak. It will show up, but you may not be able to see exactly where. There are a couple spots where it can leak. The jackshaft oil seal, as you said, transmission output shaft (clutch shaft) on the trans itself, the inner primary seal where the trans shaft runs thru, the engine sprocket shaft oil seal, inner primary O-ring, the bolts that hold the inner primary to the engine/trans, the primary chaincase gasket and the drain plug. Hopefully when you get it apart, you will see which seal is leaking. If not, replace them all. Still want to fix the leak? LOL
No real problem to solve. Just looking for tips or critical points to watch out for while working on the Road King as compared to the same project I did with my Softail. Just trying to save $500+ in unnecessary tools.
