Using a standard RS sealed bearing instead of a separate crank seal.

[yorkie_chris]

Rebuilding my 056 super. I can't find the (obsolete) PTO side crank seal.

I'm wondering whether to use a standard sealed bearing instead. Leave the inside open to crank oil and use the bearing seal as a crank seal.

Will it work? Anyone tried it? Or am I just setting myself up for another seize?

A crank seal is designed to provide an airtight seal ..... a sealed bearing will not.

No, that will definitely not work.

Look on Ebay.

Look on Ebay.

They're NLA from stihl.

UK ebay has nothing, US ebay same, german ebay had some (for 45 bloody euros!) a few months back but none now.
If anyone here has better idea I'm all ears, but I did look on ebay...

It is bearing 9523 003 4460 which includes the seal.
The seal alone is 9640 003 2690




A bearing shop here can make them custom sizes, that's what I'm going with I think. I will get a few made as there must be more of these saws around needing bits.

A sealed bearing will not hold pressure or vacuum. Let's search together. I'll help.

 

[yorkie_chris]

No I mean they will make a custom sized lip seal the equivalent of the original one.

diyspareparts.com listed them for sale, I bought some and then they emailed to say they had no stock and could not get it.

 

[yorkie_chris]

I have abandoned the idea of just using the standard sealed bearing. Clearly this was a bad idea!

 

[Mastermind]

After a quick search, I also came up empty. Remember, the 045 uses the same seal.

A custom seal might be a good idea.

What are the dimensions of the seal? They're usually on the seal, and sometimes in the IPL.

 

[yorkie_chris]

Has anyone got an 045 IPL around to check the part numbers?

The seal is DIN3760-BS23,8x33,4x4 9640 003 2690


It appears the 045 used 9639 003 2690.... could anyone with the IPL check dimensions of this? I believe there was a change

 

[yorkie_chris]

Found -045 IPL myself.... it appears this seal is the same. And just the same availability!!

23.8x33.4x4

Saegenspezi has been reproducing parts for the older Stihl saws for quite some time. I've bought some 090 re-pop parts from him with good results.

"Versand nach:Weltweit" That means he ships worldwide.

I just bought a set..

Is that right though? It doesn't look like my seal.
I believe the early type used two-part more like a normal seal, 9523 003 0440 can anyone check the dimensions of this?

You'll need to email the seller, or be the guinea pig & buy a set to see, as you're a hell of a lot closer to Germany than we are.

The 045 & 056 seals interchange, BUT the bearings are very different in width, as one locates on the snap ring in the case, the other has the snap ring mounted on the bearing.

Look at your oil tank vent to tell if it's likely an 045 or 056 series. Is your vent plastic ringed (S045) or the smaller all aluminum (S056) type insert? Also look at the different PTO side bearings in the attached pictures for the protrusion & fill of the PTO side case bore.

Your serial number in the other post you have indicated that it's an early 045 Super with the thinner bearing, but those saws are old and any used part could have been swapped out.

Even the nameplate tags are often wrong on them.

"Contact seller" in German? Nach Anrufen?

Couldn't see it so decided guinea pig was option... bought some... let you know in a few weeks!
