Okay everyone going to try to get clutches and cam chain replaced tomorrow. One thing I'm afraid I may have over looked is Gaskets. I of course have the side cover gasket but thats it. What all has to come off and what other gaskets will I need? Also is there some sort of gasket for the exhaust? I was going to try and take it off and paint it and patch a hole in the muffler.

Timing chain tensioner gasket and there is an exhaust gasket. You can just use Hondabond on the valve/head cover gasket as that's what's on it from the factory.

 

[Fourtrax]

does the exhaust HAVE to come off to change the timing chain? If so I'm missing those two gaskets. I may have to put this off another week.

Helmut, do you happen to have the actual HONDA part number for the exhaust gasket and tensioner gasket? the number bike bandit gave me doesn't come up at the local Honda dealer and I guess she's not smart enough to look them up her self without the number. :icon_ cry:

 

[Helmut]

No, you can change the timing chain without removing the exhaust, no need to remove it.

Try these part numbers.

Exhaust gasket = 18291-MN4-920 (replaces 18291-236-000)

Tensioner gasket = 12194-HC5-740 (replaces 12194-HA0-000)

Thanks! But unfortunately the only place half way close to me doesn't stock the tensioner gasket.. but did have the exhaust gasket. So I guess I'm screwed for this weekend. Unless you think there is a chance the old gasket can be re-used at least until I can get a new one.

 

[Helmut]

If you can get the old gasket off without it tearing, just put some Hondabond on it and it should be fine. Even if the old gasket does tear, you can completely remove it and use Hondabond without the gasket. Just let the Hondabond dry until it is just a little bit sticky and bolt the tensioner on. It will hold good until you can get another gasket. Really, you probably wouldn't even have to get another gasket, but it would be best. That Hondabond is good stuff, but I still like to use the gaskets if there was one originally there.

 

[Fourtrax]

Well I don't have any hondabond but I have some good RTV gasket maker that will probably work. And yeah If It does leak and I need to get a gasket later and change it no big deal.


I think I have some Permatex stuff and then some stuff in a can like spray cheese only its black and probably taste alot worse.

Yeah, it should work. If it's RTV sealant, just use a real thin layer because it can squeeze out on the inside of the engine and if it breaks off, it can stop your oil pump up. I learned that the hard way and I wasn't even using excessive amounts like you see some people use. Now, I won't use anything but Hondabond. Hondabond doesn't dry rubbery like RTV sealant, it stays pliable. I like Hondabond so good that I even use it on automobile gaskets. I haven't used RTV sealant on anything in years.

Got it! Thanks for your help, and wish me luck! I'll check back in when we are done, or maybe before if we get hung up. :icon_cool:

Good luck, if you need any help, just ask.

when you get ready to remove your top end..try to tie a peice of wire on your new chain..drop your new chain down from the top..have a long enough wire to reach all the way down the cylinder to the crank ..place the chain on the crank timming gear..then wrap your wire around the frame at the top..this will save you a head ache from droping the chain back down inside the lower engine case..been there..done that !..as for your chain tensioner..most gaskets stay on them when you remove them..if yours don't..just like helmut said..put a very light coat of sealant on it..it should not leak..if it does..here's a ******* trick..take a piece of ceral box ( captain crunch works great )..lmao..trace out a gasket..it should work..has for me a few times...for your ex gasket..it has a ceramic gasket in it where they join..most of these can be reused..the head ex gasket..can be reused too...but..your ex does not have to be removed just to take the right side cover off to replace your timming chain.

Thanks Shadetree! Actually I did remember to order the gasket when I got the rest of the stuff... must have been thinking pretty good that day! LOL Anyway the old gasket stayed on and fully intact SOOO I just left it on and put a dab of sealant on it and saved the new gasket in case it leaks. So far it does not leak. I didn't mess with the exhaust yet we ran out of time, but when I do get ready too I'll probably just order the new gasket to be safe. I want to remove the whole exhaust and clean and paint the pipe with some left over header paint I have for my car and hopefully have my uncle patch a hole in my muffler with some sheet metal. Any how, we got new clutches and timing chain all installed and back together and WOW what a difference it made. Look at my "side cover help" thread for that story. Heavy duty springs and NEW clutch plates make a WORLD of difference.
