All six nuts should be tightened all the way against the plate. Now, if the clutch continues to slip, the fiber discs could be worn to the point to where the Sleeves on the studs are too long. You can either get shorter sleeves or you can purchase new fiber disc. Make sure the clutch is adjusted properly. The Ironheads have a very touchy clutch adjustment. Most of the time, they don't want to release all the way.

Lower the primary chain adjuster under the primary but loosening the locknut and turning the adjuster screw downwards. Take the large nut that holds the foot peg on off. Take all the bolts out around the primary. Take the round inspection cover off at the clutch and remove the spring and lock nut out.

Acting like the clutch is slipping in 4th gear when I open it up, like cruising at 2000rpm then get on it

If the clutch is actiing like it's slipping, then it probably is. You need to adjust the clutch to see if that will help. To do this, first loosen the locknut on the cable adjuster at the front of the primary cover. Turn the cable adjuster inwards far enough to get a good bit of slack in the cable. Remove the round plug at the rear of the primary where the clutch is. Remove the spring and the lock nut from the adjuster. Inside, you'll see an adjuster screw. Turn the screw inwards until you feel the resistance of the clutch and then continue two more turns. Then, go back to the clutch cable adjuster and turn it outwards just until you have take out all the freeplay. Back at the clutch adjuster screw out until it's once again free, turn it inwards until you feel the resistance, then back it out about 1/4 turn. Lock the locknut down. You should have about 1/16th inch of freetravel in the clutch cable at the lever. If this does not cure the slipping problem, you may need to put new clutch fiber discs in the clutch assembly.

Good Luck

I have a 1979 the primaryharley sportster I removed cover to replace the gasket now I have no clutch when i put itto gatrher is there a secret to putting primary case on

When you took the primary cover off, you had to turn a screw back by the clutch to get the cover off. Now, you have to readjust that mechanism. This is the clutch release mechanism. First, up towards the front of the primary cover, there is a long threaded cable adjuster threaded into the cover. Loosen the lock nut and turn the adjuster barrel inward a good bit, at least a half inch or so. Now, take the round plug out at the back of the primary cover and remove the locking nut. This is not actually a nut but looks like one with no threads in it. Now, turn the screw counterclockwise until it stops. Then turn it back about a quarter turn. Put the lock nut back in and the round cap. Go back to the cable adjuster at the front of the cover and turn it out until you have about an 1/8" of freeplay in the cable. Tighten the locknut. If you still don't have a clutch, you have something wrong in the primary cover.

Good Luck

I am reassembling the clutch cable, is there an online manuel for this job or bike

I'm afraid there is no online manual available. Harley is very protective of their copyrighted material.

If you've already gotten the outer primary off the bike and the old cable out. Insert the primary end of the cable into the primary cover and screw the adjuster with the lock nut on it all the way into the outer primary. Reconnect the cable to the release mechanism with the link.

Replace the outer primary but starting the screw for the clutch release into the nut in the release mechanism. Turn the screw counterclockwise while you put the cover back on. Do not forget the gasket. Once you get the cover in position, replace all the bolts in the cover an tighten them. Adjust the primary chain by removing the top plug and checking the slack with your finger. Adjust the primary chain adjuster on the underside of the primary until you 1/2" to 5/8" up and down play in the chain. Finish the assembly of anything at the primary, shifter, foot pegs, etc. Refill the primary with one quart of oil.

Connect the cable at the clutch lever. Back down at the clutch release mechanism, make sure you have the screw turned all the way counterclockwise until it stops. Then turn the screw back 1/4 turn. Adjust the cable adjuster at the front of the primary cover out until you have about 1/8 inch of freeplay at the lever. Lock the lock nut and replace the cover over the clutch release mechanism.

If you need a drawing, contact me directly at I'll send you one directly.

Disconnect the battery, Remove the rear exhaust pipe and disconnect the large battery cable running to the starter.

Drain the primary and loosen the primary chain at the adjuster beneath the outer primary cover. Take the plug at the clutch adjuster out and remove the spring and lock nut. The turn the adjuster inward. Remove all the bolt from the outer primary and continue to turn the clutch adjuster inwards until the outer primary comes off. There are two large bolts just above the clutch assembly that hold the starter in position. One bolt is longer than the other so remember which goes where.

All i want to know is on the timing chain does the tenchiner go on top or bottom

How is the setup? You have a bar that is attached to the primary and the tensioner rides up and down in some notches? If so, that is the old setup in the big twins as well, the tensioner went up against the chain at the bottom run of chain and pushed up. Hope this helps.

Clutch cable broke at handle lever on 1979 harley davidson sporst

To change the clutch cable on you '79 Sporty, you'll have to take the outer primary cover off. To do this, you'll have to drain the oil from the primary, take the left side foot peg off, and loosen the primary chain adjuster on the bottom side of the primary. Loosen the locknut and use an allen wrench or hex key to screw the adjuster bolt downward.

If you need to know anything else, drop me a line at

Then, remove the large "plug" towards the rear of the cover. Inside, you'll see something that looks like a nut but with no threads in it held in by a small spring. This the the lock nut, remove it. Below it is what looks like another nut with a slotted adjuster bolt sticking out. Remover the bolts from around the primary cover and break it loose from the engine. While turning the adjuster screw at the rear of the cover inward, remove the cover.

The cable connects to the cluch release mechanism. By turning the "link" downwards, you can disconnect it from the mechanism. Notice which way the "link" in attached to the release mechanism. Take the "link" off the end of the clutch cable.

Break the lock nut loose at the threaded cable adjuster on the outside of the case and screw the adjuster all the way out of the primary cover. Disconnect the cable at the handlebar lever and your cable is out.

Reinstall the new cable in the reverse order. When replacing the outer primary cover, make sure you use a new gasket on the cover as well as on the foot peg boss. The "foot peg boss gasket" is very important. You'll see an aluminum boss with a threaded rod sticking out of it that holds your left foot peg on. There is a round gasket that goes over this threaded rod and seals against the boss. If you leave this off, your bike will leak oil around this threaded rod when your foot peg goes on. Make sure you specifically ask for the "foot peg boss gasket" when you buy the new primary gasket. It's just a round gasket a bit larger than a quarter.

As you put the primary cover back on, there is a spring on the primary chain adjuster. Part of the spring is in the primary cover and the other part is in the engine. You'll see how it goes in. There is a large stud in that area that the outer primary cover slides up on. Adjust the tension on the primary chain by removing the "plug" at the top of the primary cover. You want 3/4" to 7/8" up and down play in the chain with the engine cold.

On the adjuster, as you're installing the outer cover, turn the ajuster screw back into the clutch release mechanism by turning the screw backwards. Once you have the outer primary cover completely installed, you must adjust the release mechanism. Adjust the screw inwards until you feel a resistance, then back the screw off about a 1/4 to 1/2 turn, insert the "lock nut" and spring, and install the "plug". Then, using the cable adjuster on the outside of the cover, adjust the cable. Add oil.

Having problems with the belt drive getting the cover off the clutch cover side

I'm confuse a bit but I'll try to help. You say you're having problems with the belt drive and getting the clutch cover side off.

The heading on this post says you have a '93 XLH Sporty. The final drive belt is on the opposite side of clutch on a Sporty. You didn't mention what type of problem you were having with the final drive belt so I'll try to help you with getting the clutch cover off.

To get the primary cover off your Sporty, you've got to take the nut off the clutch adjuster rod. There should be two round access covers on your primary cover. The one in the middle top is for checking the tension on the primary chain and adding oil. The one at the rear in the middle of the large round place in the cover is the one you need to remove. Under the cover, there will be a spring and a lockplate. The lockplate will look kind of like a nut but won't have any threads in it. Remove this lockplate. Now, you'll see a nut with a screw in it. Turn this screw clockwise until you can remove the nut.

Now, you'll have to loosen the primary chain adjuster. First drain the oil. Underneath the cover, you'll see a threaded stud with a locknut on it. Loosen the locknut and using an allen wrench, turn the screw out loosening the primary chain.

Now, remove the screws from around the primary cover. There are 13 in all. They are different lengths so make sure you keep up with which goes where. Once you get them all out, you should be able to remove the cover.

How much work is it to take off the cover on a 1980 ironhead sportster 1000 cc side where the shifter is

Not too much, if you are a fair mechanic. You probably should get a service manual tho. Basically, you remove the foot pegs and anything in the way, remove shifter, clutch cable. Drain the trans oil, then pull the cover. A couple parts may fall out, that's why I suggested a service manual.
