Husqvarna 162, 2x 266, 268 Frankensaw Project

I have also used a heat gun, aim it at one side, then when the part farthest away from the heat is too hot to touch it is ready. If it starts to smoke (assuming it was clean of oil and sawdust to start with, since they will smoke earlier than the paint), then the heat has been on that spot to long and move the gun to the opposite end of the case.

I don't know what temp my little toaster oven gets up to, I just know that I turn the dial to 4 minutes, the timer dings, then it is warm enough. There is no temp control on it. 4 minutes on my toaster oven is just before the case half start to smoke, figured this out through trial and error.

Maybe the smoke is the clue!

So reading through the service manuals I have one of them says to put the piston ring down in the cylinder to check the gap. If it measures over 1 mm it is worn. The 162 is gap of around .88mm but the 266 is over 1 mm for sure. Guess I need a ring for that one.

Brian

Quoting myself, good trick huh?

Need advice. For giggles I put the new ring in the recovered 268 cylinder. There is only about .009 inches if gap between ring ends. This makes me think I should replace the rings in both the 162 jug and the 266 since they measure literally 5x what that new ring does for gap. I have no experience here. The service manuals say 1mm max but that is .039 inches, almost 5x the new ring measurement with the new ring at .009 inches.

So I finally am to the point to mate some of the case halves. I do not have the tool for "pulling" the crank into the bearing/case. Bolts are to short. Is there a way to do it without the tool? Freeze the crank maybe?

New 266 ring has .007 inch gap so wow, they must wear quite a lot. I HAD a new ring for the 162 but I was not paying attention and stuck it on the 266 piston which is 50mm not 48mm and then broke it trying to take it off (stupid mistake).

Ordering a new one now.

There is a lot of good info in this thread. He is involved in a project like this and needed some help with what parts fit what saw.

 

[briantutt]

Solved the square hole round peg grommet problem on the 162 case. Drilled out to .900 now the round grommet I can find fits well.

Problem was I could not find the grommet for the rectangle slot it had.

About ready to mate case halves. The service manual refers to using grease on the gasket between the 2 halves. What kind do you guys use?

Brian

 

[briantutt]

All bearings and cranks are set. I ordered some Hylomar blue to hold and seal the case gaskets just need it to arrive and one more gasket set.

Notice the middle 266 clutch side case. The chain catcher mounting area is an odd ball one. With the rounded top. Finally dug through ipls online and found part number is 501 53 11-01 but cannot find one. [emoji35]

My 162 is dual thin rings, werent they all the same?

 

[briantutt]

apparently not, all four of these were single ring including the 162

 

[briantutt]

Finally received the last gasket set from that large auction site. Seller and shipper in China. Notice bottom right corner....no wonder it took so long to get here.

Cut the heads off some long 5mm screws for guide pins. Holds the gasket in position and avoid an Oops!

 

[briantutt]

A friend helped me face the exhaust port and open the bolt threads from M5 to M6 on the 162 cylinder so I can use the bolts I have. Getting closer.

Brian

 

[briantutt]

Got the 162 ring from the Greek today and the Hylomar, let the case mating begin!

Brian

 

[briantutt]

Gap on the 162 is now .006 with the new ring. Much better!

Brian

 

[briantutt]

Hylomar is on the 268, gasket is in place, that half going in the freezer. Plan to use heat gun to heat bearing on the other side in an hour and hopefully the 2 halves slip right together.

Brian

 

[briantutt]

268 is mated and torqued up. Is it normal for it to feel a little tight and this point? I can turn the crank but it doesn't just free spin. Is this normal?

Everything looks correct.
