McCulloch Chain Saws

[Maintenance supervisor]

Sorry, really not trying to write a shop manual. If it would be easier to pm you my phone number I might be able to explain it better verbally.

I don't really understand how a bearing separator kit would help with this. But i also have never used one.

I a, gonna be honest i don't know what your talking about here. This is my first time going this deep into any saw so im new to all this.

I just reread your post! When you say you can't remove the "outer" bearing you mean the part holding the seal! Well simply put it doesn't come off its part of the ball bearing pack, one is needles one is ball. The seal must be pried from it.

Yes this is a lot closer to what i needed to know, so how do you pry them out? and how do you get them back?

This is an actual tiny seal puller , I personally like it ,the end is hooked to get inside the seal and then pop it out with the pivot.
Seal I just pulled
You can make a screw driver flat head with a hook or try a pick. Just dont ***** up the aluminium saw housing.

I think i may have actaully got the wrong crank seal for the needle bearing. If its true that you can't dissamble it then there is no way i could get the seal i have it as it is to ridgid.

I use a large deep well socket to set the new seal in place, it must be deep enough to clear the shaft and the same size as the outer circumference of the seal.
I use my vise on the needle bearing on by putting the cup and bearing in the vise together and slowly closing the vise ,making sure it goes in squarely.
Fyi everyone fudges a seal or 3 so always have an extra one on hand the first couple of times and a tiny jeweler's hammer sometimes helps tapping them around the edges to seat them squarely.

Here is the seal i got for the needle bearing https://randysengine.repair/product...5-555-570-690-60?_pos=13&_sid=bcba1924c&_ss=r

Here is the one i needed for the ball bearing so i got the wrong seal fro that one https://randysengine.repair/product...c-6-10-7-10-10-10?_pos=9&_sid=e1d5795a8&_ss=r

its all starting to make sense, and it seems due to me getting the wrong parts.

That looks right? I usually go with skf 6119 .
But rigidity shouldn't be a problem diameter would be.

The one i pulled out was a bit smaller and way for flexiable i was able to pry it out with a screw driver. But because of how ridgid the one i have is i can't push it in .

Whatever that metal ring is it don't look like it belongs in there. You don't have to remove the bearing and its cage but that ring looks like someone left and old seal in there?

 

[Maintenance supervisor]

You might only pulled the rubber out of the seal.

 

[FreakinCoolUsername]

Yep that was it. I thought it was an outer race, so i left it i didn't know the rubber would separate.

Now i really would like to do the ball bearing seal any suggestions for how to go about that, obviously step one get the right seal.

Would like to thank @serdie for this perfect Super 250 cover. I will not be painting anything on this saw and one more go at the chain and I'll think it will be dialed in.

 

[Gumneck]

With serdie's kind gesture, I need to pay it fwd. I haven't touched these Macs and not sure I plan to except maybe the Super 10 even though its in worst shape than the others. But if someone needs a part for shipping cost only just PM me.

Thanks bunches and bunches.

What torque settings are others using for 10-32 rod bolts?

On the ring left from the seal. I use a punch from the opposite side and knock it out of that aluminum piece. Removing the larger seal. I use a flat screwdriver and pry it out from the center. Bend the crap out of it. Youre not saving it so no big deal. Ive used the drywall screw method successfully also. That tool pictured is badass! I like that.
