The INNER primary cover has an oil seal where the transmission shaft goes through.
You'll need to tear down the entire primary drive to get the inner cover off.
Some notes:
The engine sprocket nut is 160-180 Ft/Lbs of torque, with RED LocTite!
This is going to take some power to break it loose (think impact wrench)
The central nut holding on the clutch pack is a LEFT HAND thread!

I'd be careful with the heli-coils. Once in they can really be a problem to get back out once they're in place and go through the heat and cool process for awhile

SOURCE: oil leak at inner primary

06 Road king inner primary leak where shift lever comes out, seal was leaking...Under warranty fixed no charge, no further issues!

I have heard of this same leak on the V-twin Harleys due to normal motor vibration "unbalanced" which is normal on the older models the 2008's and newer baggers have a differant mounting system that eliminates the vibration/ jumping/ loping/ which again is a normal Harley engine

I resently replaced my inner primary with a belt since then i still have problems oil leaking from my primary i shut down all my oilers but i still have a large access of oil leakage


Are you sure it's oil and not gear lube?

Sometimes the seal behind the transmission drive sprocket/pulley goes bad. (I had this problem myself)

Next up could be a seal behind the engine crankshaft sprocket/pulley.

Finally if you have an oil line from the oil pump to lube the primary chain (which you no longer have), remove/plug the line.

I have an oil leak on the primary cover on my bike. How hard is it to replace the gasket. I am a small engine mechanic but have never worked on a Harley.


If you can work on small engines, you can work on a Harley. A Harley is just another machine just like anything else out there. It's not rocket science. On your wide glide, simply find the primary oil drain plug on the underside of the primary back by the derby cover and drain the oil. Remove the screws including the ones for the oval inspection cover and the primary cover comes off. Remember to replace the two small gaskets on the two screws in the inspection cover. Once you have the primary cover back on, refill with oil through the derby cover opening. Stand the bike straight up and fill until the oil level is even with the bottom of the outer clutch shell. Do not overfill or your clutch will drag.

Good Luck

The gasket on the right side trans cover on my 1996 883 sporstter is leaking,I want to replace it,but I am not familar with how to do it.


There is no gasket on the right side of the transmission. The only things you have on the right side of the engine is the cam case cover and the front belt pulley for the final drive. Got to this site and try to identify exactly what is leaking and I'll try to help you. http://www.bikebandit.com

Just changed primary gaskets and all seals on this side i have oil dripping never been in gear just started up could it be crank breather problem


Did you change the seals behind the front belt drive pulley? The front pulley is made of cast iron and the final drive gear is made of hardened steel. It's specifically made this way so that the pulley wears instead of the expensive and difficult to replace final drive gear. When the splines in the pulley wear, the pulley loosens up and the tension on the "quad" seal behind the spacer is lost. This allows transmission oil to run down the splines of the final drive gear. Check the oil level in your transmission and see if it's low. When you start the engine or ride the bike, it'll leak a spot about the size of a half dollar. If you wipe that up, it will not leak anymore unless you start the engine or ride the bike. You'll have to pull the front pulley off to check the splines for wear. If they are worn, Harley makes a kit to repair this with.

Now, it could still be the seal in the backside of the primary. A lot of people make the mistake of putting this seal in and assembling the primary with the seal left dry. When the engine starts, the mainshaft starts to turn and the friction burns the lip of the seal up before oil can get to it. The seal is destroyed in the first ten seconds or shorter. When you replace the seal, always put a gasket sealer around the outside of the seal and put some oil or light grease on the lips of the seal before you assemble it.

It's not your crankcase breather as that is at the top of the heads. The two large bolts that hold the air filter backing plate on are hollow and the crankcase breathes through these bolts into the air cleaner.

Oil coming from behind the primary case cover


There are several places that the oil could be coming from. And, it could be either engine oil, primary lube, or transmission lube.

First, check for a leak at the cylinder base on the rear cylinder. I've seen that area leak badly enough to make it look like the primary is leaking.

The primary could be leaking from the seal that mainsaft runs through or the starter jackshaft seal.

The transmission could be leaking from the large final drive gear, or the front belt pulley could have become worn allowing the quad seal behind the pulley spacer to leak.

To repair these leaks is not difficult but you need a few special tools. Especially if your going to remove the front belt pulley. You need a device to hold the pulley while you put the 150 foot pounds of torque on it with the special socket you'll need for the nut. You'll also need a torque wrench that will torque in the reverse direction since the threads are left handed.

If you wish to tackle this job yourself, please repost and I'll give you step by step instructions but I would suggest you purchase a service manual for a job of this size and nature. A picture is sometimes worth a thousand words.

Good Luck

Replace drive belt on polaris sportsman 500 1996 m0del


Usually a simple process. Remove the large oblong shaped cover on the left side of the engine.inside is the primary (small pulley) and secondary(large pulley) drive with the drive belt running in between them.Force the large pulley apart(best done by hand) allowing the belt to drop down to its center and then using the resulting slack to pull the belt over the primary pulley and thus removing it.Rotating the pulley(s) by hand may aid in this process.(think about how a bicycle chain is put back into place after it has fallen off.Same basic principle) Putting the new belt in place Reopen the large drive again(spreading it apart) and place the belt onto it first then over the primary.(again turning it by hand much like the bicycle idea).When all is said and done check the seal on the cover and make sure it is in place(if damaged replace it.This is very important to help keep contaminants and water out of this area.)and replace the cover tightening the bolts from the middle outward towards the ends.This will also help seal it up properly.

06 dyna super glide innerseal leakage & sharft seleter movement ?


I am not completely sure how the shifter shaft on you newer '06 FXD is set up but this it how the mid mounted shifter lever is set up on an older version.

The shifter shaft goes through the inspection cover on the outside of the outer primary cover. If you take the shifter off and then the cover, there is a tube that runs through the primary that the shifter shaft runs through. This tube has O-rings on either end of it. There is a clamp (for lack of a better description) on the inside of the primary that holds this tube in the primary. Take the bolt out of the clamp and the tube will come out. To work with this, you may have to remove the outer primary cover to gain access to the bolt holding the clamp. Replace the O-rings with new ones. If possible, try to find one that is the same size but made of slightly thicker stuff so you get a tighter fit. This may solve you oil leak on the backside of the inner primary if this is the problem.

But, I think I've answered this question before. There are several other things behind the inner primary that can leak. One thing is the mainshaft seal in the backside of the inner primary. Another is any one or more of the seals at the final drive belt front pulley on the transmission. Harley had some major problems at one time with the "quad seal" behind the final drive belt front pulley.

If you still have the leak, notice whether it is near the middle of the primary or nearer the back end of the primary. This will help a lot in attempting to diagnose your problem.

Severe transmission oil leak on a 04 softail. Leaked out on left side


Two places could be leaking. Primary cover leak on either side. Outside gaskets are not very difficult to replace. There is a oil seal on the backside that requires the removal of the inner primary. This is a difficult job for the amateur hobbist mechanic but it can be done. You'll need a lot of tool including a torque wrench that will torque a left hand threaded nut and one that will torque to 150 foot pounds. You'll also need a primary locking bar.

So, as you can see, if it's anything other than an outer primary cover, inspection cover, or derby cover leak, it's probably best to take it to a shop. If you do this, have them pull and inspect the front belt drive pulley while they're in there. Also, replace the transmission main shaft seal (small one) the final drive gear seal (the big one) and the "quad seal" behind the spacer for the pulley (like an o-ring). And replace the oil seal on the backside of the inner primary cover. Good Luck

Oil leak at inner primary


Most inner primary leaks come from the alternator o-ring the best thing to do is put on a new one and put clear silicone on the primary and the engine case.
