Let me start by saying how awesome this site is. The people that come here and post are so full of information, and that is great. I never had a desire to own as many saws as I do. Now I want more. I have already purchased two since becoming a member, and I am watching a third one.
That being said, I am ready to tackle my first rebuild. I looked around and found what I believed to be a good starting point. I purchased a 372xp off the bay almost two weeks ago and it arrived today. At first glance everything appeared to be in good shape on the outside. The saw does not appear to have had all that much use. The seller stated that the saw made a clunking sound when turned over. When it arrived I pulled the cord, and sure enough there was the clunk. So I had to investigate further. I stated taking things apart. Once I had the muffler off I took a look inside. The piston appeared gouged, but the rings were in place. So I took I down as far as my tools would let me.
Once the jug was off I took some time inspecting it. It appeared to be in great shape. There are a few minor marks in it but nothing that I can catch a fingernail on and it feels very smooth. The piston is shot. I guess I am just not sure how the piston looks like it does, and the jug is not much worse. Pretty quick I figured out what the cause of the clunk was. The piston rod is loose on the crank. There is way too much play. It is like a bearing came out. I do not see in parts to anything in the case though, so this struck me a little odd. If I am not mistaken the crank is one pressed together piece so I guess not it is trash.
Other than that minor little detail , everything else appears to be in great shape. I guess it means that I am going to have to split the case and put a new crank in it. It is a shame though, because there is no play in the crank and the bearings appear to be in great shape.
If someone can tell me what would cause this it would help quite a bit.
I would like to keep my little thread here going for a while to show the progression of my first build. I have already taken quite a few pictures, so over the course of tonight I plan to get them all up on here.
Thanks for all the help in advance, and I can not wait to see where this goes. I may just have to send it out for some porting .
