Husqvarna 162, 2x 266, 268 Frankensaw Project

[briantutt]

A good friend brought me four projects. A Husqvarna 162, 2 each 266 and a 268. At first glance they are very similar but once I got them apart I noticed some distinct differences. Case in point, the pistons. The top two pics are the 266, the third pic is the 162 (notice bottom of piston is way different and bore is smaller), last is the 268 (also has bottom of piston difference from 266). Started this thread to document my project and hopefully get answers to some questions and put info out there as I learn.

The 162 also has a metal gas tank. The anti vibe is slightly different, at least visually. The 162 has the best looking piston and cylinder so I will for sure rebuild that one but one of the 266 is roasted so I could use the plastic tank from that one the 162 I think. Does anyone know? Top ic is the plastic tank from 266, bottom pic is metal tank from 162. I haven't measuerd a bunch of stuff yet but all four saws are very similar in construction.

Do you know the age of each saw - serial numbers?

 

[briantutt]

Yep. All four still have their tags.

The 162 is likely to have a different clutch to the more modern saws, its a coarse thread. Looks like the 268 is a closed port, thats the one I would be rebuilding.

 

[briantutt]

What does closed port mean. The pistons on the 162 and the 268 both have similar piston designs.

The clutch side case is pretty screwed up on the 268 but I think I can use the case half from the roasted 266. I will have to measure some stuff but one of the two looks almost identical.

The 268 piston looks like my open port Gilardoni piston. The closed port piston should be windowed.

The 162 and both 266 have a course clutch thread. 268 is fine pitch. Good call.

Nice!

As they left the factory:

- the 268 is from 1995 week 41, so a "plain" 268 (not xp) with an open port top end

- the top 266SE is from 1983

- next 266SE is from 1984 week 42 - this means that both 266SE supposedly had the smaller carb (15.9 mm venturi vs. 17.5 from some time in 1985)

- the 162SE likely is from before 1982. I don't know any reliable way to "decode" that number plate, however it looks like the crank bell in sight was dated 1979.

Of course you never know what has been changed at some point, with an older used saw....

 

[briantutt]

Thanks SawTroll! These all came from one guy who has passed on. They were his saws on the farm. I think he just ran them till the quit and went and got another one. I don't think they have ever been tinkered with it of course you never know.

I did something similar 2 years ago, built a 266 from a box of parts. Be careful choosing your case halves, some of them have different hole locations for the top cover screws. My 266 top cover only has 2 of the 3 screws line up. I think a 268 top cover would have the opposite screw line up, but not sure. I wish I would have known to check for that, but it never occurred to me.

 

[briantutt]

Plus 1. I will check that in a few minutes. These are the little things I am looking to catch before I deciding what parts can go where. I think I will make a matrix of what is bad on each saw and then carefully look at the donor parts. Then decided how many saws can be made from the 4.

You were right. The 268 case halves both have extra holes between the carb area and the jug. All the other ones do not have this. The other 3 cases also have a small hole under the carb that the 268 case does not have. Last difference is the 268 case is only machined about half way down the clutch side on top. The others go almost the whole length over the bar stud area.

I just put a 162 top end on a 61 white top rancher 2 piece ignition and aftermarket 272 muffler...big thing w a good sized outlet hole toward the front right....It has coarse clutch threads....haven't run it yet but looing forward to it. The 162 is closed port the rancher was open w/smaller ports so could run well...

There is some good video of Spike60 going over differences and similarities of some of these models on you tube that you might find helpful.

Case splitter is in the mail. Now I can move one with this project. I think I will get 2 saws easy reviewing the parts. Maybe 3 if I can make a case half work for the 268.

I was at my dad's cutting today and mentioned I was going to try to press the piston wrist pins out. He told me I should be able to just heat the top of the piston with the torch and the pins will push right out. Does that work?

[David Young]

Yep. Most of the time..... Ha don't need heat

 

[briantutt]

Not sure this is a new idea but now that I have a case splitter I realized it can be used to push the bearings off the crank. Just get the bearing splitter behind the bearing and then use the case splitter to push of the bearing splitter. Much faster than screwing around shimming behind the bearing splitter.
