Dealing With Dirko...?

[SteveSr]

Hello,

Does anyone have any good suggestions for applying a thin, round bead of this stuff to seal clamshell cases?

My last experience I recall wasn't very fulfilling. I ended up with as much on me and tools as on the machine!

Anybody ever try loading this stuff into a hypodermic syringe sans needle?

Thanks,
Steve

I don't know if it will fit but Oreillys sells the pointy tips for Permatex tubes.

I'm not sure how different it is from Yamabond, but I just use q-tips to apply a thin coat to both surfaces I'm sealing on the Husky clamshells.

I use 1194? or 1197 cant remember but I use a paint by number brush. I just open the tube and dip the brush right into the tube works very well.

Sounds like an interesting idea! Use a small disposable brush. I would think it would have to be pretty stiff because Dirko is pretty viscous! Where do you buy yours? Got any web links?

At work, we use syringes to apply a bead of sealant. They're available at farm supply stores without any kind of license or paperwork.

Sometimes I use a popsical stick to spread it thin the scrape the excess with the other end works good imo

I usually use a carb tuning screwdriver.

and that's why his saws are always in tune...

I use the longer included nozzle while cutting the tip to as small of an opening as possible. The black heartish shaped twisty thing is a must and it is still difficult to dispense. I wish Dirko came in a smaller single use tube.

I usually use a coating, not a bead. One surface is all that's necessary if you apply enough. Glob into the groove (on the Stihls) using the Andyshine approach and then smooth it with my finger. Using the long dispenser will waste everything left in it. Just poke a small hole in the end of the tube and apply from there. Wipe clean afterward and tighten the cap. Hardly any waste and only a very small plug to remove the next time you need it. Should be able to find a tube for around $8.00. Lots of folks think it's a Stihl product and don't use it just for that reason. It's not. Made by Elring and widely used in Europe. Great working time. Stays rubbery. Easy to remove. Can be applied to only one surface and is usable immediately upon assembly. My sealant of choice for years.

I've never perfected the use of Dirko, like said it's about the messiest stuff on the planet. Whenever possible I use Motoseal, works just as good on the Stihl crankcase pan and way less messy. I use a screwdriver to smear it around..

 

[Jeff Lary]

I have never used or seen Dirko so I don't know if my way would work probably not. As for where I by my brushes I get them at Walmart craft / kids paint section about 10 or 15 in a package.

Dirko is what Stihl uses when they put their saws together, or so I've read...

Plus one on motoseal. I put on a rubber glove and dab it on with my finger.

Here is what I ended up with... I found an old nozzle from a silicone caulk tube and it happened to also fit the Dirko tube. I also use the dispensing "key" this time and it made dispensing much more consistent as one hand could work the key and the other position the nozzle. I do think I will try to find some small paint brushes to smooth out the bead junctions. A deck screw in the used nozzle makes it a breeze to remove the Dirko plug for the next use.

Note to self... RESIST any urge to clean up the squeeze out BEFORE it completely cures!

I've never had a problem to seal a clamshell engine.I was using Dirko HT for years,good stuff,never had a single issue.I tried the motoseal,it holds really good but i dind't like it because it was to liquid,few months back i came across the threebond 1215( i bought it to seal my KTM rocker cover).Really expensive stuff(i paid 35$ for 250gr tube) but is beyond everything i've seen.It withstands gas too easy and it is a little stiff when you apply it which i like a lot.I put a glove on(those thin gloves for medical exam) and aplly the stuff with my finger,nothing more easy than that.

 

[PogoInTheWoods]

Threebond 1184 is what many folks use as well. Very good stuff. But again, a sloppy sealant to apply, imho. I just don't see Dirko as a messy sealant. Quite the opposite, actually. Will need to check out the Threebond 1215, too. Thanks for the tip.

I use motoseal less than 7.00 a tube sometimes.
I use a q-tip to evenly spread it on surfaces.
I've never had a failure with dirko honda
Yamabond treebond etc.
It's all good stuff
I just prefer motoseal

I have some red high temperature gasket maker made by Permatex I think, I may try it on my next clamshell. It's not quite as fibrous as Dirko but may work...I'll have to check and see if it is fuel resistant..
