Looking at rebuilding a 562xp and thinking about leaving the crank stuffers out. Wondering if I need any spacers to replace stuffers or not.

562/560xp without stuffers will become 555....non xp 
Transfer covers are different on the 562/560 as well.562/560xp without stuffers will become 555....non xp
I understand that it will be closer to a 555 than a Xp designated saw. Just looking for longevity from it. Thinking that the stuffers are nice but take away from the nylon caged bearings getting lubed as good as they should so they don’t fail..

Mix 32:1 or 40:1 instead.......?
Why would I mix fuel different… all saws I have are recommended for 50:1 mix and 2 of the saws are late 70’s early 80’s era saws and never had a bearing failure

This +.....
Your 70s&80s era saws are not of X-torq, 2-Mix design...
Here Mix (fuel + oil) flows differently through the lower part (bearings) of the engine....

Less mix flow (Husqvarna says -30% less) means less oil for bearings...
Not of X-Torq design…your right..they are not over engineered to make the most power with out long lasting performance….that’s why they have more hours than a normal x-torq saw …they were designed for longevity…from what I see is that once I removed the stuffers from crank there was more than double surface area for fuel/oil mix to lubricate bearings along with the fact of not holding all the extra heat to the bearings without proper cooling
But the x-torq comment doesn’t mean much to me…being that the x-torq saws were built a while before the 562,550,etc. saws were even thought about with less bearing failures. One because they had metal bearing cages and two because there was no crank stuffers to hold heat, hamper bearing lubrication along with a slightly loose stuffer can cause undo crank vibration that could hamper bearing life..
The husky 5 series saws have some bearing issues. The nylon cages break. I’ll have to look up the service bulletin again but they have a new part number for crank bearings.
Every place I searched for bearings and part numbers all led me back to nylon caged bearings
They’re all nylon cage. I think they may have had a bad run of bearings. I’ve been meaning to talk to someone at Husqvarna about it, not sure I’ll get a straight answer but it’s worth a shot.

I think you answered your own question. You want to remove the stuffers to get more oil to the bearings, but you don't want to just add more oil instead ?
