Learned something today. **** open a set of cases and realized the case screws were a coarse thread vs. almost every other one I have that were a fine thread. Must be an early version....but the point is I can no longer assume 346 cases & case screws are all created equal....

( Still getting used to the look of that crank when "center" is set by the bearings and pto case side....leaves more distance on the flywheel side by quite a lot... but that's how they have to be! )

Hello Weimedog! Good to hear from you. Are you talking about the main case bolts or cylinder bolts? I remember that I learned from one of your videos that somewhere in mid to late 2000 they could be either one, at least on the plastic cased versions of 340-350, and the Jonnys 2145, 2150. Any more I just keep the bolts with the case I tore down. What year 346 are you working on?

With the plastic cased 340-350 that's true. I guess I didn't expect it on the metal cased 346xp's. AND you really have a mix of the two threads through out the cases...coarse on things like the oil pump, fine on the cylinder screws, bucking spikes and the 6 case screws. Coarse on the ignition coil and the rest of the plastic parts....

Building 3 346xp cased saws.... really didn't look at the tags, they were all from a box of parts. I've had to separate out the parts to piece together the saw in "mock up" so I can catalogue what I need to complete these projects...

Good to know as I have 2 346's of 2011 & 12 waiting to be rebuilt. The 353's of that period may be affected as well. Sure don't need any cross-threading going on.

Just want to commend you on all your videos. I have sure enjoyed watching and learning from all of them. Like you, I'm a tinkerer, and love to wrench on this series of saws. Keep them coming as I really enjoy them sir. You have a wonderful Thanksgiving

I never been through this series like some of the others. So this is good info to know.

Most of mine were easy fixes just needing a topend etc. Never inside the crankcase yet.

Thanks for sharing.

IPLs tells me that the part number for the case changed by 2003 week 5, as did the number for the bolts - so that may be when that change occurred?

Must be... and to the commonality of parts between the 350 series........(Wish I had videoed some of this!!)

You can adapt the top end...did a couple of those. Top end from air filter through to muffler.
Tank/handle and handle bar. Anti vibration stuff. Throttle & linkage
Bucking spike
Pull Start & clutch side cover.
Chain brake parts inside the cover & spring stop on the cases.
Ignition
Multi Function Switch
muffler & related hardware

Some things you can't
Obviously all things related to the cases & hardware
Crank Shaft is different on the PTO side
Clutch
Chain Brake Handle/lever and mounting hardware...
Top cover

Chainsaw Repair
