Flywheel side looks thicker ,is the bearing the same ?

Flywheel side is completely different.
Takes a bigger bearing and seal.
The pto side is the same on a 064 066 660

Most of the broken ms440 saws i have picked up to rebuild lose the flywheel side bearing for some reason ,the only 066-660 saws i had never failed there though .

Most people don't have a 64/66 with 10 hp and run 404 and use it for production

We are going to need someone to produce a nice forged steel polished balanced crank!

I could name 20 different loggers around my area that production fall that run 066 660 661 and not a one run .404. .404 just isn't built for a saw chassis that size. Everyone runs 3/8 50 gauge.

Got this fella fixed and ready for some stock base line cuts this morning.

Gonna try to get it ported today.
I got a cylinder here that somebody stuck a screwdriver in the exhaust port for a piston stop,gonna raise till it's cleaned up and see how it runs. Might be 96 or higher. The I'll port the cylinder on the saw another way

I thought the bearing was the same... I built an 064 with AM 660 bearings. The seal surface was definitely different, though.

The od is the same but the id is bigger on a 660.

Was gone till after dark but had to try it out quick. Only made 2 cuts with a stock cylinder and mm then switched to the ported cylinder and made 2 cuts but I'll run it in the morning and fine tune things

 

[RI Chevy]

Nice.

Headlight dedication right there....

That cylinder is 99 123 126 82 and maybe 165lb of compression. Only cut 012 from the chamber. It was 104 125 130 79 stock so I didn't want to lower it much.
