Husqy 350 45mm build help

[David Young]

Aftermarket 346 is the deal of the day here, if you use it get a caber ring and OEM circlips.

What I am about to share is my experience and opionion. I can back it up with pictures.

I bought two no name 365 kits here for rediculously cheap I got what I paid for and they are the worst I have ever seen. To ship them back I am throwing good money after bad. Hyway, Golf, Meteor, tecomec and even some farmer tec (to a lesser extent)are useable products that are fine for the price. I would personally be very weary about no name kits. You will have a 20 dollar paper weight.

I like the sealers like hondabond or motoseal for the bearing cap. They really set up and create a bond that is kind of a pain to remove. I use permatex 518 for the base gasket replacement because it is easier to break, easier to clean and you dont have to wait.

A sealant i know that can be used is available at most auto supply/parts stores. its called VersaChem Type 1 sealant gas and oil resistant and dries rock hard
good for 425+ continuously it is great stuff.

CLEAN the base / plastic case well before installing the bearing cap.... whatever sealant you use HAS GOT TO BE FUEL RESISTANT SPECIFICALLY .... on the Brad Snelling one I just pulled apart he used loctite 515 or 518 for the base gasket delete. it was WELL stuck on there. i would do the exact same thing.... I used 515 at first, then switched to 518. I think i'll go back to 515... 518 is a little thicker.

Both 515 and 518 is recommended to be used on metal to metal joint, none of them are really suitable for 350, and Locktite doesn't recommend them to be used on plastic either, probleby due plastic vibration. Both has maximum tickness layer on 0,01", and even if you somehow could get the layer to be stable on plastic without cracking later, you may face the limited layer tickness in the space between the seal, plastic cage and bearing cup....put in another word, it may never cure....

Picture say more then words, this white sealant Husky used on those 350 build around 0,02", twice the recommended max layer on 515 or 518.....


To check out if 518 get a good grip on plastic I figured out it was best to do a test. Gone let it cure for 24 hours before I pull the bearing cup again, next will be to get activator and do another test.

it sticks

 

[Chainganger]

All I know is from the formal data sheets for 515 and 518, not recommended for plastic.

 

[Tor R]

it sticks

518 has absolutly no adhesive effect on plastic.
I wouldnt trust 518 at all as gasket layer on 350.

I am not 100% sure but I belive Husky use Dow Corning, their is # 503 26 72 01, it's probleby silicone type

 

[Chainganger]

This finding, together with the data sheet warning, not recommended for plastic, is a big deal for those using or thinking of using 515 or 518 for the sealant between the case and bottom of bearing cup!

I did let it cure for close to 36 hours, there was absolutly no adhesive effect to the plastic.
I didnt had any seal inside, who would actually made it far worse since the tickness needed is way outside the specification from Locktite.
I know I will defently not use 515/518 on 350 bearing cup system.

 

[Mattyo]

Interesting. ...thanks for the update. Guess I gotta go find some yams bond going forward

yup, something else then 518 not saying 518 is bad but it has it's limitation....maybe it would had better adhesive effect if I had sanded the plastic a bit but 518 is still way outside it's specification in the crack agains the seal.
If you do a test please post up what you figure out.

 

[Mattyo]

well, at this point I'm not worried about the dozen 350's i've done w/ 515 or 518... but in the future i'll have to pick up some 1194 or something akin.

nice thing about the anaerobic sealer is that if it gets in the crankcase it won't cure, so its not as hazardous to bearings

 

[Tor R]

Anaerobic sealant is a wonderful sealant, but most 1 component chemical (sealant/paint) has very narrow application.
Locktite 518 datasheet say maximum 0.25mm tickness layer, will it cure with 0.5mm tickness?
If it doesnt, preasure test may work same with vacum test, but if it didnt cure totally the no-cured places will be washed out before or later

Speaking about tickness, I've worked as industrial painter for 10 years, I've seen the result of too tick layer paint on boats, everything looked beautiful, after a year it more look like some had shot a crocodille and dragged the skin over the boat, spectaculare effect indeed lol

 

[idiotwithasaw]

So what's the news, what happened with this 350?

 

[ABarrick]

FWIW, Hondabond and Hondabond HT both seem to work well. Handabond is messier to deal with than Dirko but once it sets I think you could take the fasteners out and it would hang in there lol. It adheres very well if the surface is prepped correctly.

 

[Mattyo]

Doing one now with some 1184 threebond for the joint between the riser and case.

 

[idiotwithasaw]

Used 1184 on the last 350/346 build I did, got it at my local outdoor power sports store, saw it hanging there, had to be fate. Lol. I haven't done as many as matr, but I feel like I'm getting pretty proficient with this series of saw.

 

[BGE541]

We all just can't break down and buy Dirko???

 

[BGE541]

Can i reuse the bearings/seals or do i have to replace them. I believe they were installed new oem from the dealer who used the orange stuff. They probabaly dont have much on them.

Soak them in a small glass bottle of mix, tried it on an old set that were stiff and two weeks later they were smooth as a baby's bottom. Also I have a good link to a closed port 45mm p/c if your looking.

Thank you. I will see how this does and will let u know. So far i think its demon possessed. Ha

 

[BGE541]

They can be a pain, I like them but still tell Mike I dislike them lol I just finished one last night and may go back in and do the full 346 intake track, they are a pain.
