562 XP - Air leak, crank bearing seal...

[CapitaineHaddoc]

Hi guys,

Yesterday my 1st ported 562 had a big issue, I know immediatly it was a massive air leak.
Back from work, I removed the clutch, and that's what I found:



You can't see it on the picture, but the seal spring was partially outside the rubber seal.

I checked which parts I need to fix this, but there's something I don't understand,

As you can see here, the seal is sold separately. If it's true, it's a really good news, because bearings are crazy expensive here (2 bearings + seals + crankcase gasket > $150 in France), and partstree won't ship to France.

And these crankcases are a PITA to split.

So is this real? Could I change the seal only?

PTO bearing is the same as they use on 346, so yes, you can buy seal separate.
You can't buy the bearing without seal, when you purchase the bearing it come with seal installed.

As you can see what model the bearing 525434201 cover:

Partstree is a wonderful site to check up on things

Why do you think that happened to the seal?

Absolutely no idea...

Thank you, so if I remove this broken seal I can just replace it with splitting the case, am I right?

150.00 wow that sucks but I believe tor r is correct.

You dont need to split the case for exchanging seal.
Chain side seal is also very easy to get out, they are not stucked as hard as normal side.
I just use a little screwdriver on that one when I remove it on 346.
You should study the bearing close after your seal is out, something ripped that seal suddently according your story.

Normal price for the whole bearing (chain side) is around 40€ in Norway, gasket sets are like 12€, the other seal 10-15€, bearing flywheel 15€. I may miss by 10€ in total
Also, 25% in taxes.
150€ seems high

That's my worry too. It's like replacing a lean seizure piston, gotta do some forensics before you just replace. Otherwise you'll be doing it again and risk further damage.

I have no idea what would make your seal do that Bill. I'm sure one of the Husky guys here will chime in.

As I mentioned in the 346 bearing thread, I am doing something horribly wrong. (Unless the inner lip of the 346/562 bearing isn't as sharp as that on the 385/390)
What is your secret for getting these seals in?

I ruined 2 seals, and ended up splitting the case to replace the bearing.

i really dont know if there is difference in instal procedure 385 vs 346, I've never had 385.
All i did with the few 346 I have had is to oil them and carefully mount the seal. Did the same with my 133 who have kinda same style bearing.
It's not that I have long nails, 1mm maybe, but use my nails a bit also, I just have lots more controls with my fingers versius screwdriver
What I dont do is to mount the seal and knock it in.
Dont know if this make sense..

Edit more info lol

 

[Tor R]

I just studied 346 PTO bearing, it doesnt have sharp inner lip bearing, it's angled a bit so install is kinda easy.

Is this a 2011 562?

 

[lmbrman]

wow- for $150 I can get a complete crankcase with crank, bearings, seals installed, new from husky

Yeah I didn't realize how good we have it here several people that travel to other countries have told me how ridiculous saws and parts are.

@Tor R

We are lucky to have you as a member here sir. You are always a source of excellent information.

@Genius

35mm film is perfect to help guide the lip over the center of the bearing.

 

[panteliss]

bearing flywheel side 560-562 = 9 euros
bearing clutch side 560-562 = 20 euros ( maybe little more or less i dont remember exactly now )
seal flywheel = 5-6 euros
seal clutch = 5-6 euros

i speak for OEM what is this 150 ??????????? parts for aerospace ?????

 

[tickbitintn]

That seal looks like it was shoved out from the inside by something that shouldn't be there....
I hope I'm wrong and that when you pull the seal off the bearing is fine....
Please take a pic for us and post it.

@Mastermind, thank you so very much for your kind word.
I learn alot from your guys each day.
The way members help each other, how they share tricks and experience amaze me. This forum has become everything I hoped it would be, and I am very proud to be member here

 

[huskihl]

I'm not familiar with a 562, but this lip...is it in the crank? Like a 272, etc? Or is the lip on the inner race? What does the seal ride on?

Prices are just crazy high here. Best example, a husky 288 cylinder kit = €528.83...

The clutch side bearing alone is at €55.
