About a year ago, I purchased 2 051s from the bay that cost about $120 each shipped. I didn't really care if the saws were in bad shape, what I wanted was an inexpensive pro saw to learn on. I've been involved in other projects so this is the first chance I've had to look at them. One of them had my curiosity up, so I was really itching to look at it. See for yourself.
An early model 051, right? Well have a look at this...
If you look carefully, you will see a manual oiler there. Now, I'm wondering if this is an 075 in disguise. So I go for a closer look.
The stud come up all the way to the top of the head, so 075, but the good news ends there. Many of the bolts around the saw are stripped (does anyone know the size of these socket head cap screws, m series but I don't know what size or pitch) I hope to be able to oversize tap them or re drill and tap. So now will have a look through the exhaust port. First at the piston and rings.
I've worked on some homeowner saws before, and now I know what you guys mean by the ease and simplicity of a professional saw. I have never worked on a saw that was intended to have a long life, so I really don't know what I'm looking at here. These rings look really worn, right? Here is a picture of the cylinder (people who use cellphones to take photos of saws ought to be shot). Hope you are able to make something out of this bad pic.
I'm sure you can't make anything of that, however the cylinder is shiny and smooth and scratch free in all the places that I'm able to see through the port. I'm able to grab the starter cup and turn the crank through multiple revolutions without much resistance. The slower I turn through the compression cycle, the easier it is to turn and I can hear the air squeezing out, so I know I basically have no compression without even pulling out the gauge. So my question at this point is, am I looking at a new cylinder or the whole P&C kit?
