1996 Electra Glide Primary Cover Oil Leak

I just noticed that I have a new oil leak that has started on the bottom side of the primary cover. Bike was rode last week and set for a week and there were no leaks then. I rode the bike today for only a couple miles and within a minute it started to drip after parking it. I'm wondering if retorquing the bolts would be a good starting point to stop the leak. Also does anyone know the torque spec on the bolts as well.

SOURCE: have devolped a small leak on 2005 road king.

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

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: There is an oil leak around the bolts that hold in

Hello,

The oil you are seeing may very well be from the bike sitting. I have worked on many bikes that have had similar problems. The oil bypasses the rings and gets forced out the top of the cylinder. Once the bike has been used for a couple of days, sometimes a few days longer, the rings expand sealing the cylinder and thus no more oil. It would be a good idea to examine the cylinder bolts too to make sure that the oil is not leaking from the cylinder head.

When a bike, or any motorized vehicle or tool, sits for an extended period of time, parts that are supposed to be lubricated by the motor running will dry out or shrink. This can cause a decrease in engine life and costly repairs. Always try to start your bike, even if you don't ride it, and let it run through the warm up procedure everyday.

Even if the oil leak stops on your bike, you should still have the exhaust leak fixed. Grab the exhaust pipe, when cool :o), and see if you can feel any slack by pulling on it. I would spray a penetrating oil on the bolts, let it sit overnight, and then try to tighten, or replace, them yourself.

Regards,

Oz

SOURCE: Small gas leak on 2005 Honda VTX1300R

I would suspect and look for any cracked or damaged rubber or other flexible type gas line/s from or to the tank, and where they connect to. That would be the 1st most probable location of leaks. Then the tank or carburetor/injectors.

Small plug on primary cover leaking oil 09 dyna super glide


Not likely too much oil cause of the leak but too much would cause clutch release/dragging problems.

Describe this plug more. Is it a rubber plug that maybe filled a mid shifter shaft hole that is not being used as the bike has forward controls??? I would be surprised to find a 2009 DYNA that ever was fitted for mid controls but stranger things have happened that me not being aware of something. ANYWAY describe the situation more. What do you call the front face of the primary. To me that would be the front of the cover towards the front of the bike but I am thinking you are referring to the cover as you look at it from the side???? The mechanic may have no idea why it is leaking now but he or she should have and idea why it is leaking.

PLEASE POST a comment advising what you find out and/or more information etc. if you do not find out and need more assistance.

Where are the filler holes for ****** & primary located on a 2005 Elec. Glide Standard


The "filler hole" for the primary is the derby cover. Remove the derby cover, stand the bike straight up and pour the oil in until the level is at the bottom of the outer clutch shell. The "filler hole" for the transmission is on the right side chrome cover where the clutch cable goes in. There should be a large plug that takes a hex key or Allen wrench to remove the plug. The oil level should be between the lines with the bike standing straight up.

Good Luck

Harley said i have a wet clutch added oil they recommended through derby cover now oil comming out of breather tube??? don't want to ruin anything shut it off and started searching on line ...only got...


Your 04 Electra Glide does indeed have a wet clutch. Your primary case holds between 36 - 42 ounces of oil. Stand the bike straight up. Remove the derby cover from the primary cover. The oil level should be just up to the bottom edge of the outer clutch shell, the shiny aluminum ring. Do not over fill as the clutch will drag and you will not be able to get the transmission into neutral with the engine running. Now you said that you have oil coming out of the breather tube. What breather tube? The transmission has a breather tube but that's the only one. Your engine's crankcase breathers are located in the heads and exhausts the crankcase pressure into the air filter. This is required by the EPA. After a while, oil mist will build up in the air cleaner cover and begin to drip out. You have to clean this out from time to time. Your transmission holds 20-24 ounces of oil and you fill it through the chrome end cap on the transmission on the right hand side of the bike. There is a plug that takes a large hex key or Allen wrench to remove. It has a dipstick on it. With the bike standing straight up, the oil level should be between the two lines.

Good Luck

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

How do i check the primary oil in my 2005 harley davidson electra glide. i changed the oil and added 32oz of oil as directed by the owners manual but i cannot see the oil in the clutch inspection cover....


if you put 32 oz of primary oil in the primary case then you have enough oil in there already. Never put more then 1 full quart or you will have leak issues. The way I do it is to have the bike upright and level and look through the primary inspection cover and as long as the chain is in the oil a little bit then your fine.

Wondering does the primary chain get


The primary on all late model bikes (1985 and later) are known as "wet primaries" because they have their own lube in them. The newer bikes like yours came with H-D's Syn3 20W50 oil in the primary.

To change the oil, stand the bike up as straight as safely possible. Remove the derby cover. You'll see the clutch assembly. Notice the outer clutch drum is made of aluminum. Inside that is a black disc. This is the clutch diaphragm spring.

To drain the primary, remove the drain plug at the rear of the primary on the bottom. Replace the drain plug and refill the primary with oil until it's just to the bottom of this diaphragm spring. Usually 38-44 ounces. Do not overfill as too much oil will make your clutch drag.

Replaced clutch, oil, cables...1998 electra glide classic..bike is hard to get into neutral once it is warmed up..


Make sure you do not overfill the primary. when putting the oil in the primary, have the bikes standing as straight up as possible. Add oil only until it comes to the bottom of the clutch spring. If you put too much oil in the primary, the oil will get in between the plates when the clutch is released and act like the oil in a automatic transmission torque converter. It will continue to drive just enough so that you cannot find neutral with the engine running.

Otherwise, you must make sure all clutch adjustments are correct. Loosen clutch cable all the way. Adjust clutch release adjuster behind derby cover, all the way in and back off one half to one complete turn, readjust cable for 1/8" freeplay.

How do I change all my fluids on a FLHTC 2005


There are three areas that you have to service, engine oil, primary oil, and transmission.

To change the engine oil, underneath the transmission, you'll find two drain plugs. The drain plug nearest the left side of the engine is the the engine oil drain. Warm the engine a bit and drain the oil. Change the oil filter. This is a messy job so put something down to catch the oil as it runs out of the filter. Replace drain plug and refill with oil.

The plug nearest the center of the transmission is the transmission drain. Remove the plug to drain the transmission. Once drained replace the plug and refill the transmission through the transmission fill hole in the chrome cover on the right side of the transmission.

To change the primary oil, underneath the primary outer cover very near the rear of this cover is a small drain plug. It takes a Torx wrench to get the plug out. Remove the plug to drain the oil from the primary. Remove the derby cover over the clutch. Refill with oil through the derby cover hole.

Your bike probably came with H-D Syn3 oil. You can replace the oil with this or any other oil as long as it carries a rating for use in a diesel engine. Here, it must have an API code of "C", example "SJ/CG4". Four quarts of engine oil, Add three quarts of oil and check. Fill to proper level with the fourth. Your dipstick is marked with a "Full Cold" and "Full Hot" mark. Fill to "Full Cold" mark and check again after warming up the engine.

Use Syn3 in the primary or 30 weight oil, 40-44 ounces. With the bike standing nearly straight up, the fluid level should be to the bottom of the clutch spring, large black disc in the center of the clutch. It's a diaphragm type spring.


Use Syn3 in the transmission, 20-24 fluid ounces. Check with the dip stick again with the bike standing straight up.
