Sold Stihl 066/660 Cylinder for hybrid

[Speciosa]

Hey guys how goes it? Im looking for a 660 oem cylinder for my 064. Plan is to end up with a ported 064 hybrid. Just need a cylinder to start with. Love the saw just always want a little more power to pull a 404 chain. First post so please forgive any faux pas.

I thought 660 and 064 had different bolt pattern on base? I could be wrong, dont do much w stihls.

 

[Speciosa]

Huh, first ive heard of that so im not sure. Do you know if the 660 and 066 have the same pattern?

 

[cus_deluxe]

I believe so, but again im not 100% on the 064 bein different. May be some overlap from 064/066/660

 

[Speciosa]

So just did a little more reading and the only thing that needs to be changed is the 5mm to 6mm cylinder bolts. So unless im mistaken the 066/660 have the same pattern.

 

[cus_deluxe]

Nice, thats pretty minor.

 

[Speciosa]

Yeah i think so, that'll be the easy part. The hard part is finding an old cylinder .

The hardest part is getting everything centered

How do you mean? Like drilling and tapping the holes?

Just centering the jug, since the 066 bolt holes are a little offset compared to 064. I’ve never done the Mod myself, but maybe it’s easier than I think.

You read this thread?

I read chainsaw jim's thread about it and breifly looked at the one you posted. I didnt realise the cylinder holes needed to be slotted i thought before only the gasket needed slotting. Reading comprehension really was never my strong suit. But i'm not afraid of a little hand work to get it finished.

I was born and raised on Prince of Wales, But have moved and been living in Wasilla for the last 8 years or so and currently Hawaii. Just listed the house and moving to the Coeur D’ Alene area tho

Thought you might have been down there cutting timber with the ol’ 064

Idaho is a cool state, i lived down there in riggins for 8 years before moving up to Alaska. I miss it from time to time but i sure appreciate the great white north.

I was cutting timber, just not around south east. I picked it up to have a big saw in the truck when i was working with a crew clearing right of ways for the power company around Tonsina. Only needed it a couple times but was sure glad to have it.

In the middle of one now. The prior builder retained the M5 bolts and there was no slotting of the jug base I found.

One note, the case needed to be relieved for the 54mm tunnels to clear the sides.

 

[Speciosa]

Right on, glad im not the only who likes a good hybrid. So how much material did you have to remove? And what piston and cylinder did you use?
