BGCG
« on: July 11, 2018, 12:48:19 am »
Ok here we go. Long time sand bagger first time on a post of any kind other than fence. I'm about ready to finish up installing a new bevel gearcase gasket and came across what seems to be a stupid simple question but one that has me thinking none the less. First I will explain that the bike is a 2001 in fine shape unlike the owner. I am no stranger to wrenching on bikes, I do all of my own maintenance and repairs. I ride and I ride a lot from tank full to tank full and maybe food stops in between and I am always looking for like minded people to ride with seems easy enough but it ain't.  Ok enough about me here's my question of the day that I assume has been asked more than the amount of letters in the preceding ramblings.....

My Haynes manual calls for me to "21  Apply sealant to the gearcase mating surfaces on the crankcase where to two case halves meet. See  Figure 87"
I can only assume this instruction is in lieu of installing the new metal gasket that I was able to order and pick up from a somewhat local dealer?
Being I am new to forums and posting topics please feel free to point and laugh or send me packing. I do so solemnly swear to keep my future posts to less than a pictures worth of words and get right to the point. For those of you willing to engage I thank you and to all those apposed,  well......

welcome fresh one...

dunno how much you have read prior, but this has just been an issue recently discussed.. I assume you are installing a new metal gasket, behind the output assembly to the engine.. correct?
I never liked the Haynes books, just because it sounded like the folks that make underwear... pun intended, so from the factory manual, I assume you are talking about the 'horizontal' case split area, where they say to apply 'sealant'. when doing this new install, with a new metal gasket, I'd sway mysellf to not picking at that horizontal split line (figuratively, as in "don't pick at it") and coat the new metal gasket with a copperized shellac type sealer, like a "head gasket of olden times" was done.
this comes to mind, as an example...

or, some hairspray, Like the Flo chick uses, either works... but it's really overkill..
whatever you choose, use it sparingly.. as long as that little crack either side of the case split line wasn't compromised, a light , and I mean light, schmeer of any sealant will be fine, and ONLY on the area of the split, either side...
(the metal gasket was a superceded designed part, to replace a paper gasket,  and doesn't call for any sealers... supposidly..   but I have an old can of Indian Head coperized head gasket spray, so I err on the side of double condoms, and double bags, one on my head, and one over her's...... if you get the joke.) :great:

best of luck, and welcome... :great:

Thank you for the perfect answer. Being an owner of a Harley shovel head with a sidewinder big bore kit I have the exact copper goop needed as it's required to keep those stupid heads from developing a leak.
 Thanks again for putting my mind at ease. It's true the Haynes manual is not as detailed as it should be but has served me well (until now) because the bike has served me well and has needed nothing more than regular maintenance until now. Another evening in the garage and I should be back in the breeze!

the metal gasket has a clear coating on it. No additional coating is needed. The reason for a dab of sealant at the case parting line is because sometimes there's a machining mismatch there, and the height offset would allow a seep to develop. Just put a finger dab on the mismatch and install the gasket dry. Good luck, Steve

Thank you Steve. So, do we all feel that changing the water pump oil seal is a MUST? Seems the consensus would be yes but after looking at mine while the water pump is out it is still seated, what looks like properly. I am of the mindset  of it ain't broke don't fix it. The job seems easy enough if it were to fail at a later time but I'm not nearly as smart of a human as my dog thinks I am!

I bet your dog is only buttering you up for pets and food treats and keeps what he thinks about your smarts to itself.....

if it ain't broke.... is always my thought process... let it be.
I've seen brand new seals pop out in a week, and I've seen seals from the factory last 90k miles... without a drip...

When I did mine, the water pump looked good, unlike the bevel drive gasket. I left it alone, hasn’t leaked in 3 years since. If it ain’t broke...

Brooke, my dog read your reply and he couldn't agree more....
