Bar Plates or guides.

[KenJax Tree]

Implying that I don't maintain my saw and that I do have access to air? I clean my saw everytime it is used, unfortunately I don't have an air compressor or easy access to one so I spend alot of time with brushes, picks and a rag, removing gunk from all the crevices on the saw. That plate stops most if not all the debris from collecting in the chain tensioner area, just saying.

Thats not what im implying at all im just saying i dont have plates on any of my saws and never had a problem. Air is the way to go even a little 12v will do the job.

Typical inside bar plate. Outside is usually mirror image without oiler slot at top.

Outside one is most often missing/lost in the leaves, snow or carelessness.

I see that that one has been run at least once while installed backwards.

In some instances, the bar plates are referred to as spacers or spacer plates.

In other cases, separate spacer plates are used in conjunction with the bar plates in order to center the bar further away from both the crankcase & from the clutch cover. This is important when a chain is used that cuts a much wider-than-normal kerf, & could potentially do some serious damage to the saw itself. Clear as mud?

Actually upside down.

It was on my C5 when I got him. Used as an outer. All kinds of goofy.

Like I posted, outers are most often missing.

keeping the steel of the bar from eating into the magnesium case, guiding the chain from the point of where it leaves the bar to the sprocket, and providing the case some small measure of protection if the chain jumps off of the bar.

The purpose of that is it stops the oil from coming on thru the hole and not going down the rail

the bar plate seems to offer some protection from chips and oil gunking up around the chain tensione
