Holy crap. 40 bucks a set for aftermarket is steep. I'm used to husky bearings. Someone on here can lead you in the right direction for the aftermarket number or if they are stihl specific and that's a good deal. You should be able to use aftermarket as stihl buys them from some one else too. It's one of those things.... For example... Mercedes motor mounts are made by Lemforder. If you buy them aftermarket from Lemforder and not mercedes, they are the exact same mount with the Benz emblem ground off and cost 75 bucks less. Gotta love it.

Good job so far with the case splitter and cylinder clean up. It's just not worth doing all this and only going half way. :clap:
 
Boy do I feel like an A hole haha. So I broke down and ordered the bearing through the dealer for 42 dollars and it will be here on thurs, after that comes the assembly of the cases which I'm praying will be painless
 
Never meant to make you feel that way. I think your doing great. My first actual rebuild ended with a saw that died from going only half way. Ended up parting it out..lol.

You may have made a great choice and at least you know it will be right. A reliable saw is what your trying to end up with and that's just a small upgrade to get you there.

I have thoroughly enjoyed your write up so far. Keep up the good work!
 
Thanks guys, the eBay seller refunded the money so in reality the oem bearing was only 12 dollars more than what I had paid.

Now when I install the new bearing I will try to heat the case in the oven, my question is since I have the chain brake assy still attached what temp can I heat it to? Don't want to end up melting the Chain brake and have to replace that too.

Also I'm from Morris county

Just take all that off. 2 little clips is basically all that holds it on....

I use a toaster over at 250 ~ 275 degrees. The shop manual specs "appriximately 120C". It also specifies removing any/all rubber parts, levers, etc., which I do.

not far at all ..Im 10 minutes away from Bridgewater Commons.
as pogo said...the brake stuff is easy off, don't risk it and once youve done it you can do all the late model Stihls. take a pic then take the clips off. the spring is the only somewhat tough thing.
 
Thanks guys ill look tonight and see where the clips are and try to get it off
 
Case is together, clutch side bearing didn't go in as smooth as everyone said it would, but it's in. The case however did go together easy, I tightened all the screws as right as I could get them with a screwdriver, put the gasket in dry and tapped the crank on both sides and it Spins great.

What is the best/easiest way to install the seals and what should I know about installing them? I will be installing them tomorrow and will be assembiling as much as I can of the saw tomorrow. Thanks guys


 
I always drive them in "gently" with a socket and extension that matches size of the seal. I often Smear a VERY thin bit of sealant on the outer lip to give it a bit of extra seal but more to help it slide in. Make sure it's glinting in squarely and if it starts getting crooked, tap more on the other side. :). Drive it till it's flush with the case... (Some saws seals get driven till the seat... Others that are stihl guys can tell you if this is one of them.)
 
Great 036 thread here minus the pics until they figure out how to transfer those links to the new system.

As for the seals, the main thing to consider as stated is get em in straight. The sealant on the outside diameter is less significant than lubricating the crank and inner diameter rubber lip to avoid the seal getting hung and flipping outward as it is pressed into position. Lube it well. I do use a sealant on the outer surfaces as well...Dirko in my case.
I also use an appropriately sized washer (larger than the bore) under a socket positioned directly against the seal to help assure a clean and flush press into the bore.
 
Did you get the OEM oil line kit? If so, definitely use the spring and cut the line to the spec. Use a heat gun to give some flexiibiliity to the line for installation over the barb on the pump and to get the thimble into the delivery end.

Looking good. Another thing, tho. You should really use at least a t-handle torx bit to tighten that case. A torque wrench with appropriate extension and torx bit are obviously the optimum way to go. A screwdriver handle torx driver may not provide the torque to keep that case from leaking.
 
You might double check your flywheel side crank seal. I cant hardly tell from the picture, but it looks like the seal is still on the tapered part of the crank stub, instead on up on the shoulder where it needs to be. May just be the pictures, but it'll be easier to check now rather than later. Those seals set kinda deep if I remember right....
 
Double checked and the seal is in all the way it seems. Tried tapping it in more and scan feel its bottomed out, the key way has an off set at the end of it, whaling way should that offset face?

So the oil line was a pain, not as terrible as I have heard it was but definitely a pain. I tried to put it onto the oil pump first then slide it up from the clutch side but the angle was too much and it didn't want to slide in so I had to take it back off and work it up off the oil pump. We're getting there, got the middle on, still waiting on the carb kit from the dealer which will hopefully be here by mid week and still waiting on an answer on which way the offset on the key goes for the flywheel.

Still need to order the upgraded clutch drum which I will order this week.



 
The round part goes into the crank, but the flat part that grabs the flywheel has an offset on it, I don't want to put it in the wrong way and effect the timing of the saw

Also I don't have an IPL so could someone help me with the clutch install, the worm gear goes into the oil pump, it looks like the bushing goes into the worm gear, then there's a washer you can see in the picture, I don't know if this goes on then the clutch goes on or? Thanks guys, I forgot to take a few pictures during the breakdown
