oil pan gasket...hylomar?
pulled my oil pan and ran it through the parts cleaner to wash out any metal debris from when my bottom end went out and was reading manual on oil pan installation. the manual mentioned using hylomar on the flanges. is this a necessary sealant with the metal gasket? the oil pan is super clean and the mating flange on the transmission housing is also clean. the engine is out of the bike right now so it's super easy to line up the pan and gasket. i was wondering if the use of hylomar was to help keep the oil pan in position if installing from the rear like you would when the engine is in the bike.

I've never had that repair but if the shop manual says to use it I would. Not a big deal and better to be on the safe side.

i couldn't find hylomar anywhere but did find an equivalent product at pep boys, permatex super high tack gasket sealent #80060. cheaper than hylomar too.
|
it is just to help keep it aligned during install. any similar product will be fine if not used in excess!

Yamma bond is excellent too!

HD Service Manuals mention Hylomar occasionally but don't specify which Hylomar (they make several products). I found Hylomar Blue online for about $10/oz (quite expensive). I also found an equivalent Permatex product #85420 for about half price. It even says "Compare to Hylomar Blue" on the package:
https://www.autozone.com/sealants-gl...ant/166684_0_0 The Permatex #80060 (mentioned by "grasscat" above) is a bit less expensive than the #85420 and will probably work ok. All 3 cure (let all cure a bit before putting stuff together),are fuel and oil resistance and provide sealant properties in both low and high temperature applications. Halomar Blue and #85420 are rated for a bit higher temp applications than #80060. Of course HD recommends the highest priced product. |
I wouldn't use anything, Gasket will work just fine. If it's a newer viton covered aluminum one, it's definitely not needed. Those are excellent gaskets.

This is relabeled hylomar (polyester-urethane based-never sets ups, stays tacky). Same color, just a little easier to apply, can get at Orielly, advance, autozone, etc. Use brake cleaner to clean up or remove. YD
