The ported 359 arrived last night.

Husqvarna 550 MKII. They have updated the crank bearings once again. Was awhile back this year. Just getting around to updating in places. So look for the SB.

MKII still having failures.

15hrs on that MKII.

Working on getting the serial number where they started putting the updated bearing in at factory.

That was quick. = New 550 MKII saws from this have HQW bearings at 20231711671

Bearings made in Germany

That's really disappointing to hear. Any word on the 562s, as well?

I'll have to check the serial on my 550xpg. Still unfueled, so maybe I'll send it down the road.

I still blame 50:1.

Run good FD oil and at least 40:1. Folks running at least that I dont hear or read about issues.

Yea, that's what everyone says. Some suggest even going higher oil at 32:1 for the x-torques and 5-series.

I switched to 40:1 after my 562 ate it's bearings in 2023. It was a hard use saw that was mostly bucking firewood, but always kept clean with chains/bar in good order and only made it to 600 hours or a little more.

Quick touch and some fine tuning. 20" 3/8

Next will be the 24" 3/8 ripping to see.

I haven't exceeded 20" with my stock 359 yet. Seems to be a good fit, though I'm tempted to go down to 18" in the future. I know a lot of people run 24" on them stock.
