case gasket materialcase gasket materiali split the upper and lower case and not sure what kind of gasket material i should use. should i use silicone/RTV or should i use a form-a-gasket compound?
i bought a manual cd and it really doesnt tell me shit. i cant even find the torque settings for any bolts not even the head bolts so i'm a little disappointed with it and i'm going to send it back. any help or sugestions would be apreciated Pete
gasketPete,
There is no gasket material here and most of us have used the Honda bond or Yamaha bond. You can get it at any Honda parts counter or Yamaha. Use it sparingly though. Even the Honda shop manuals don't list the torque values at least that I can find. Do a search here and you should come up with what you need to know. I wrote them down in my shop notes but don't recall what they would be at this time. It's called some-timers you know. Don't throw away the CD, you may find it handy one day. Just my 2 Cents worth,,,,,,,,,,,,,,,RW

Silicone sealers should only be used on window panes and not anywhere near the inside of an engine (IMHO). Even if you put just a thin coat on the surfaces; when you bring them together small droplets can be squeezed out then harden and float around and do nasty things to the free flow of oil to the bearings. I've never used Honda bond so don't know if it's silicone base but I have had good luck with permatex aviation sealant: http://www.permatex.com/products/automo ... lant_a.htm It not only can be used by it self to seal engines ect. but also helps if you have a rubber seal that keeps leaking (like the rear seal on a ford 351 v8 after three new seals and gallons of silicone---this stuff stopped it permanently). Also unlike other form-a-gaskets sealers it doesn't harden up so it's easy to take things apart ---maybe to retrieve that shop rag you left inside the engine:-) Good luck Clarence
Re: case gasket materialOthers have suggested HONDABOND and YAMABOND.
As there are 2 types of this material I suggest ya get "HONDABOND 4" OR "YAMABOND 4" as the type 5 is a sticky material. ..................lm
hondabond sounds greatperfect!
thanks for giving it a name on the cd they just call it "packing" so i'm that closer to reassemlby. now its my pistons i got them out of the cytlinders and i want to put new rings on them. the cylinders themselves are in good shape and there isn't any scaring on the walls. i'm going to hit them with a glaze breaker and if i get decsent clean up i would like to use the same pistons. the dome is stamped 050 and they are also in great shape. does this sound like a good idea?? i'm doing this all on a "i'm so broke i can't be fixed" budget but even with a new set of rings and a clean cylinder hone i think i will still get solid compression without going to the next size up on piston and rings. this is also a spare engine i bought to give me some experience so when i have to get into my good engine i know what i'm doing. plus if it doesnt work right it's my own fault any input is greatly appreciated Pete
pistonsdoes this sound like a good idea??
Pete, From a professionals point of view, he would shutter and bark a resounding HELL NO. From a shade tree mechanic point of view, you would be surprised what you can do to these things and get away with it . At least for a while. Check the gap between the ring and land for excess gap,check the ring end gap at the top and bottom of the cylinder for allowable gap and make sure the bottom of the piston has allowable clearance at the bottom of the cylinder. Then hope to God ya don't get piston slap. If you watch what you are doing closely it will run but I didn't tell you any of this stuff. I would advise you, if you don't have one, get a shop manual at the very least and it will get you through the basics of this engine. Do let us know when you get 'er running'. RW
