Lock it

[jamie2548]

Hey all.

You been such alot of help lately I thought I would ask some more info.

One question is . What brand "Locktite" is the best? I have used locktite on vehicle engines that doesnt want to let go when pulling motors back apart.

The other is . What sealant is the best for the clutch cover on the wifes monster. It has no gasket so I was wanting to know what brand would be the best to make a good seal?


cheers.

 I use loctite 222 ,basically because that's what i had,  reading the tech sheet though looks ideal for aluminium and low strenght, not to strip out the aluminium on removal, though, i wouldn't use locktite on any of the engine crank case.

Ducati  recomend Three bond sealant which is a silicone based,i think Ducati sell it, have seen it on ebay and a bike shops, MCAS, Though i don't think there is anything special about, just a different American name for something  we can get  here,

I use permatex ultra grey RTV silicon gasket maker, can get it at autobahn, Repco, and most auto shops.
Used on all my case covers on the bike and car and 4wd, no problem

Loctite comes in colours - different colours have different strength. Purple is lowest strength, followed by blue, followed by red. Red needs heat for disassembly.

In addition to the Permatex sealant mentioned by Rob, there's also Yamabond, Hondabond etc, which is all the same stuff.

If you want the best advice on how to sort oil leaks, talk to a BSA owner

Any chance you learned ones could provide the rest of us with some idea of when to use loctite (ie. is there somewhere you shouldn't use it) and what flavour you should use for different applications?

Yep, or basically ANYTHING British!!  They invented the "total loss" oiling system! In one end and out the other! (Generally NOT through the combustion chambers!!  )

BSA = Bits Stuck Anywhere!!

But mostly Bastard Stopped Again!!

Thankyou very much. Much appreciated. Oh and Dragon

I generally don't use loctite. For most of the stainless M6 cap screws threading into aluminium (stator cover, clutch cover, etc etc) I just put a little dab of grease on the threads to prevent galling.

If it's a screw or nut that's likely to get hot (valve inspection covers, headers, calipers, etc), then I'll substitute copper anti-seize for the grease.

I used blue loctite on the rotor bolts, after cursing the bastard in the factory who used red loctite there. I plan on using a dab of blue loctite on my cam pulley nuts when I get around to reassembling my heads.

The only place I know people use the red stuff is crankshaft nuts and clutch basket nut.

Fanks Suzy.

Of course I have absolutely no idea what those parts are you are talking about.

Brad black would probably be the best man for that info.

Loctite can be identified buy a white power residue and or a coloured  plastic looking stuff left on the thread of the bolt after removal.
So if it was on the bolt on removal put loctite back on it when you put it back together.

Though from my limited experience with Ducati.
Ducati use loctite on the brake rotor retaining bolts,and rear sprocket nuts (DSS)the low strength 222 purple is ok for that application.
Loctite is used through out the engine, gearbox assembly, 271 red loctite would be more suitable there.
Or as per the workshop manual

*Use loctite only on steel or stainless steel, if used on aluminum it would have the possibility to strip out the aluminum thread on removal.
ie the crank/engine cases don't use locktite, i use anti seize here and ather numerous threads.

*Note Ducati use a lot of stainless steel thread inserts in aluminum, ie the rims were the brake rotor mount. then loctite can be used.

If in doubt don't use  loctite just carry a good set of tools/ allen keys to tighten every thing up as it rattles off.  

And What Suzy said,beat me to the post

Yep it was the rattling off thing that I am concerned with ... I just wanted to know which things are safe to glue down.

Thanks

If you go for a ride on bevel drive and nothing falls off you haven't ridden far enough.

if you have a manual on the torque settings page it will tell you where you use what grade of loctite and also where to apply grease to a thread. I only loctite where the manual says and on anything that doesn't use it i use a small amount of copper anti seize, this practice alone saves wellnuts from tearing up saving a small fortune over time.

It's funny, the factory manual is virtually useless for the home mechanic, it's either way too technical and discusses special tools or it's overly simplistic with dodgy translations. I rely on the exploded parts diagrams for reassembly most of the time.

I bought a new clutch cover gasket last week for just over $10.

Much better than any goop you might use.

the only "goop" i use is the ducati threebond, as used in place of most paper gaskets these days
