Not even a month ago I had a primary case gasket fail. I replaced it and today (maybe 2 weeks later) It failed again! Now I can handle a little drip every once in a while but what I can't handle is a lot of case fluid coating the left side of my tire and brake effectivly making both useless! If this causes me to ever lowside it will be the end of my relationship with Buell (which sucks cause I love my Buell...when it's running right and not trying to kill me). I almost feel like welding the damn thing shut so I don't have to worry about it (yes I know how stupid that sounds). Thanks for letting me vent. I'm gonna go take my bike apart so I can fix in first thing in the morning and still go on my ride tomarow. -Barge | ||

Kano.... when you take the primary cover off... use a soft abrassive to slean the mating surfaces...like a socuring pad or something...and use it LIGHTLY... Then, use some HTV...enough, so that when you torque it back down, you have to use a rag to wipe the excess off.... Ride it, let it cool, torque again..and see what you come up with.... Its not impossible that your cover is slightly warped either, though, not likely... Chase | ||

Something's not right. Did you use the updated coated steel gasket? I torque everything down to factory specs and never have a problem with the primary. Check the basics, and please let us know how it works out. (Message edited by djkaplan on June 17, 2006) | ||

I'm gonna try to get the Steel gasket first thing in the morning and as far as torque gose...don't really have a torque anything so i just go till they stop moving (I know...it's pathetic). | ||

beg - borrow - get a torque wrench. Not something you will use everyday, yet something everyone should have in the tool box. Being as since it is fathers day.....never know what sears will have on sale. | ||

lightly snug all the bolts down and then incrementally tighten the bolts in some kind of cross pattern. if you suspect a warped outer primary, remove clutch cable and put the primary gasket side down on a large piece of glass and ck for flatness. blue yamabond works pretty good. good luck, tim | ||

I cant tell if your kidding or not? How can you bitch when you dont even follow procedure? do you even know the order for torquing the bolts? Torque specs are there for a reason if you dont torque the bolts in proper order and ft.lbs you can not only cause leaks but warp and wreck things. use the money you save by not taking it to a dealer and buy a friggin torque wrench | ||

service manual states the buttoning up procedure for the primary cover. bolts should be tightened in a cross pattern. you should then start the bike and go for a short ride and re-toruque the bolts. once again in a cross pattern. Sears sells an inch-pound torque wrench for $45 US, it's a good investment. I am assuming that you know you must remove ALL of the old gasket before installing a new one. | ||

Patrick, where are you finding that in the manual? I've seen other people talk about it before, but my manual just says "Install primary cover and gasket onto left crankcase half using mounting screws. Tighten screws to 100-120 in-lbs." I doesn't mention a cross pattern or a retorque. I'm looking under the "Primary Cover" heading in section 6.2. It's page 6-5 of the 2002 M2 manual. | ||

START YOUR PATTERN FROM THE INSIDE middle of the primary. Harley expects you to use some commen sence and know alittle about how tourqe spreads through a primary or something. Another thing they expect you to do is follow thier procedures. Also keep in mind that alot of primary gaskets esp for shovel head and the big twin have that plastic bead on them that alot of people think it somekind of sealer. actually its there to help spread the tourqe and let the primary "move" when its being installed.

do you even know the order for torquing the bolts? There is no order for torquing primary bolts in the manual,maybe you mixed that with the cam cover bolts.And there is no retorquing procedure anyway! Even so,a cross pattern is common. But there is definitely a given torque. No one should blame his bike for his own ignorance.No one should work on his bike without knowledge and proper tools.

I do know that using a torque wrench is important and i do know that you should install and tighten the bolts in a cross pattern. What I also know is that the service manual that i ordered a week ago hasn't gotten here. Sanchez: If those numbers are correct then I thank you for your knowledge and i'll check with the dealership while i'm there just to make sure I have the right numbers. I'm not retarded when it comes to working on an engine just new to buell (or any harley product) and poorly equiped (at least at this time). Just got a call and have to go get a gasket. -Barge | ||

Don't get discouraged Man, leaks do suck and fixing a recently fixed issue is worse but it's all part of the "joy" of wrenching your own ride. Just follow everyones suggestions (especially the cleaning of gasket mating surfaces and torque procedure/ value) and you will be fine. Good luck  | ||

Just had to go dig out the books.... '99 and earlier is 80-110 inch lbs '00 and later is 100-120 inch lbs Go figure. Wasn't trying to bust ya on the torque wrench. Just a thoughtful reminder that all home mechs should have one. Or two or three of them. | ||

using a cross pattern, and tightening incrimentally allows it to seat evenly. if you go in a circle, you may get the right torque readings, but, have a high spot, that wont seal.. The Case itself, doesnt even use a gasket. No, there is NO SPECIFIC order for the primary cover liek there is on the cam cover.. But, heads are the same way...think of a small block chevy, each bolt/stud has a specific order, but, the intake, or the oil pan, dont, just start from the most inside, and work out, adn around, in a cross pattern. If you cant swing a torque wrench, Auto Zone, adnusually O'Reilly's will "loan" them out, you pay a deposit on the tool. For something like this, it doesn thave to be perfect reading, JUST CONSISTENT. And come on guys, no need to tear him up, not everyone was brought up working on bikes/cars.. Its cool, we'll learn him ;D Chase | ||

"...'00 and later is 100-120 inch lbs..." I always have a running fear that I am going to accidentally set my foot pound wrench (instead of the inch pound one) and spin the tops off the fasteners. Luck so far but I'm sure it's been done   | ||
| Kano832003 |
Almost just did that...on my way to advance auto parts for an inch pound torque wrench... -Barge | ||
| Buellben |
has anyone mentioned checking the case breather? if the hose is pinched or obstructed in any way that will cause the primary to leak. | ||
| Patrickh |
Sanchez, Sorry if my post was misleading, I was just trying to indicate that a service manual should always be used. There is no specific order stated for tightening the bolts in my 99-00 Cyclone service manual, but like any other situation where 2 metal parts are mated to form an oil-tight seal, a cross pattern should be used...sorry | ||
| Seth |
Kano, ...Assuming all went well with your primary gasket replacement... Were you able to set the primary drive chain tension properly? (...not busting balls, just looking out...) | ||
| Kano832003 |
I actually think i have it a little too tight. as i said before, i still don't have my manual, but i just tightend it untill it quit moving and then backed it out about two whole turns. i started riding it and noticed a slight whining sound coming from the primary. guessing that's a little too tight. have to work the next two days so i'll probley loosen it up some more on wendsday. | ||
| Bomber |
K -- that is definately too tight by a lot! back her down accordin to the book (the data is repeated many many times in the KV) take a deep breathe, work slowly, and all will be well | ||

Kano: If you are going that tight with a 3/8" drive wrench then you may have buggered the aluminum threads in the engine case. While you're at the store get a thread restorer kit (Grainger sells a nice unit online from Proto) to refresh the threads in the case. I highly recommend having this in your tool box. I have NEVER had any oil leak from my Buell. I ALWAYS use the right torque wrench (I own 4 of them). If anyone is going to play mechanic you better get ready to pay for the right tools -- and that includes the manuals. If you wonder why you have to pay $50 / hour for a mechanic it's partly because you're renting his tools... | ||

This might be a little late, but you can "rent/borrow" most all tools from Auto Zone including torque renches... Just an idea for those of us that don't want to go out and buy every tool in the world  |
