I think I have found the mystery saws identification. The oil pump is on the right side of handle above the muffler. That was only on the XL-800. The 903,923,925, the oil pump is on the left side of the handle cover and pushes down. Am I correct? chainsawlady Now that I have read all the threads and checked more the grips are not on XL800. Had to be some changes on the handle. I think the 800 had white on the starter cover if I remember correctly.chainsawlady Hi Joyce, I believe the the Super XL-910 and Super XL-902 (points ignition) were both Terry saws. Like the Super XL-922, Terry stuck with the air box model manual oiler. A friend in BC has a Super XL-902 with the side oiler . They share the same IPL and I didn't dig through it to see what differences there were. There was also a later version XL 910AO with the electronic Phelon CD ignition. |

Now that we've concluded the idenification of the saw,has anyone got a drivecase cover,or some call it a clutch cover? Part # 63009-2,air filter-part#63341 I have one that fits, not the same part number, but it came on a XL903 that I found the original part for. It has been redrilled to fit, the extra hole could easily be filled. I thnk its for later model 900 series saws. I'd take 10.00 for it plus 5.00 shipping. Let me know if you don't want it, I'll put it on eBay.

Hi Oologahan,
Yeah I'll take that clutch cover.Would you happen to have an air filter as well?All of theser parts are very difficult to find.My email address is:edju1958@yahoo.com.Send me your name & address there & we'll do the transcaction through emails.
Ed

Ed I looked at your pic of the decompression valve,the saw in question is an XL-903 with a SXL-902 throttle handle/air box assembly.Also the piston looks scored, hence the low compression.The Xl-903 was an 82 cc saw with a 2 1/16 " piston, the rings are part # 55537.

That's funny,I don't have a pic up for the cylinder of the SXL-902 or SXL -903.The piston scoring is of the 540 that I put up pics of. |

I looked at the pic on your flicker account,just clicked on the pics at the beginning of this thread.

After further extensive review of pictures,IPL's,colors,etc...my best guess is it's all Super XL-902 except the piston and cylinder which maybe an Xl-903..they shared the same crank and connecting rod but not bore size.

I get what happened here,they married two saws together.It's a money saving idea that some companies dd back in the day.Instead of retooling & investing more time & money,they used what they had left over from another model.It makes sense now.So which rings do I need,still the ones you said earlier?So I have a bigger cc saw than I originally thought.Cool! More cc.'s means longer bar.LOL

Someone probably replaced the cylinder because the original was toast and not available..then patched it together with a cylinder from another model (I'm assuming XL-903 because of the decompression valve).To be sure you need to measure the bore, # 55537 rings for the 2-1/16" (2.0625") bore.

I don't have a micrometer,so do I take it somewhere to get measured properly?After all,I must be precise in the measurement & 1/16 in.is very close to be measuring with just a ruler.

For precise measuring a digital vernier caliper(with depth rod) can be used to measure the bore without disassembly,sweepleader outlines the procedure in the SXL-902 Compression thread.

If you take the muffler off and use a depth gage, like the tail end of a vernier, dial, or digital caliper, you can measure the bore. With the piston down, blocking the exhaust port, measure from some surface on the outside, next to the port, to the piston. It will be something like 0.200 inches (made up number). Move the piston down out of the port and measure from the same place to the far side of the cylinder. It will be something like 2.200 inches (another made up number, both of which are sort of what I find on my XL-500). Subtract the first from the second and you have the bore, (2.000 in this case.) Nothing to it. houseofhomelite.proboards.com/thread/6510/sxl-902-compressionA cheap plastic caliper from a hardware store will get you within 1/16 of an inch, you will be able to tell one bore from the other. |

I found a halfway decent digital caliper/micrometer on Ebay for under $20,but I've got to wait a bit to buy it.I just bought some parts from Joyce so I gotta make sure she gets paid first.

This is all making perfect sense to me now.As you saw on the pic,the valve stem was bent over on the decomp.valve.I believe this was done purposely to make it"inoperable"because the SXL-902 engine that was in the saw originally had no decomp.valve,& there was no way to install the decomp.valve rod to something that wasn't there in the first place (I hope you can understand that).I'll see if I can get someone to mic the cylinder for me rather than wait around to get my own caliper.I'm kinda racing against time here because I'm most likely having surgery next month on my SI joint,& that will lay me up for about 6 weeks.I don't know if I'll get this saw operational in time for cutting in April. |

In the mean time can you take a picture of the rings through the exhaust port and upload to flickr

I looked at pics of the rings,they're stuck in the grooves from melted aluminium off the piston due to overheating (clogged cooling fins) carbon buildup in the exhaust port and there's probably some aluminum transfer onto the cylinder wall...you maybe able to salvage the piston with some micro polishing/groove cleaning ,but I don't see an new one available(A-63781-A)..
