The Husky 42/42 special/242/246 thread

[trooney]

I just put a 42 Special together but didnt pull the clutch.

The one to left in post #4 is the last version.

I think Oregon is phasing out 242 clutch drums.
If you have the oil drive with the slots,
the clutch drum you should have is Oregon 40068, Husqvarna's part number is 501.63.66.05.

You can of course go back in time, but I think it's about as hard to find parts then too.
If so, then it's Oregon 29105, you need washer, and the drive was the same one used on 133/234/238/44 and 444, was available in both plastic and bronze.

Hope you had a Merry xmas Tor!

I definitely had that, putting together parts for the projects that will be started soon.

Hope your Christmas break was excellent.

I have the Husqvarna work gear puller. What I don't know is I the worm gear is compatible with the oil pump that is on the saw. Anyone know?

They had three oil pumps, v1, v2, v3, but unfortunately with only one part number.
v1 was non-adjustable, and was used until the middle of the 238 era, mid-1985.
Then came the adjustable, v2, which lasted until 93-94? the worm gear itself was the same as v1.
Then came the last v3, where the spline has taken over for the disc that is between the oil pump and the clutch drum.
v3 has a larger hole for the oil worm gear so that it can be installed without unscrewing the oil pump like you had to on v1 and 42 so that you got to the worm gear.

Could you please post pictures of your problem?

The PO put an incorrect drum on it. The saw won't oil because the drum doesn't engage the gear. I need to find Oregon 40068 that has the ears that engage the slots in the gear

The 242 that I just got has a ks cylinder on it, and it is putting out 200 plus PSI with the base gasket. How common is this? It really rips, and honestly it is harder to start than my 266s

I definately like my 42 Special. It cuts real good and its light. I found me a new limbing saw. I like it better than the 254 I had.

Hi, I'm new to this group, I live in Norway and find it very meaningful to repair chainsaws. Because of this I have an old Husqvarna 42. I believe it is from 1990. I originally thought I could use SKF 6201/C3 bearing on both flywheel and PTO side. I understand from what you write that SKF 6201 does not work on PTO side, I believe the reason is that the oil seal will not fit on the SKF 6201? I have read through this thread, and how I understand it, there is no PTO side bearing obtainable for this chainsaw, is that correct? Regards Harald

Welcome to the forum Harald! It looks like this site has a bearing that should work on the PTO side of the 42.

Thank you! I thought it was tested by others on this thread and that it is leaking air? Or was that a different bearing?

Hi Harald and welcome to OPE.
The crank bearing on the chain side (PTO) has been discontinued by Husqvarna, must be close to 10 years ago.

There are aftermarket bearings to get hold of (I've never used them), Duke is a seller, and the other is Skogsverktyg Sverige (the Swedish ones don't ship across the border, so you're dependent on a Swedish friend to be the middleman).

You can find new slacker 543301, but I can't say how serious these bearing shops are. And they are very expensive, over 100$ + vat & shipping.

I don't know if they have been tested and leak.
What I do know is that someone tried the 6201 that comes with plastic protection, and thought that was enough, and quite logically they leaked like a pig after a short use lol

hank you! I thought it was tested by others on this thread and that it is leaking air? Or was that a different bearing?

That I don't know, if I had a 42 I would give it a try unless you can find a parts saw and can take the existing bearing off of it to use (if it was still good).

At Magnus, someone showed how to convert the original bearing into a different one

I think I may have been the start of that project, it is based on using a bearing with the same inner diameter, but narrower and smaller outer diameter than a 6201 bearing has in terms of dimensions.
The sleeve in which the bearing will be located thus has room for a quality sealing ring.

But all this was before aftermarket crank bearings came along.

My H42 was definitely an anchor, there was a lot of corrosion inside, I cleaned the cylinder, installed a piston from another manufacturer for fun and it still works

 

[Tor R]

An excellent donor saw for the PTO crank bearing is 44/444.
Every now and then new crankcases appear for a symbolic price.

I don't know if 242 crankcases are available, in some online stores it looks like that, but my experience is that their parts list is not completely upgraded.

This is interesting information because I happen to have such a dose

 

[Tor R]

Others that have the same bearing dimensions as we need are the Stihl 020 AVP, maybe the saw was called pro. SKF. It used a retaining ring in the bearing like many other Stihls, but the bearing can be used without the retaining ring.
Then there is a brushcutter that had a bearing that was 13.5mm wide otherwise the same dimensions inside and out. I never had to go that extreme, but it wouldn't have been difficult to deliver it to a machine shop to grind off the 1.5mm.
All of these had the same sealing ring dimensions as the F.A.G 543301.

This is why I thought it is leaking, I see now it is from 2021, and they probably sell a better product now.

Well I finally got around to popping a seal out of the @Duke Thieroff bearing to see if an oem seal will fit. Unfortunately, the oem seal has a smaller o.d. and smaller i.d. than the seal that came with the Duke's bearing, so the oem seal is a no-go in this situation.
