Hi guys - New to the forum, but been lurking and getting help from this site for quite some time. So first off, thank you to this community for posting so much helpful info for folks like me.
I have rebuilt a couple saws now, and have acquired a SXL-925 for very cheap. As expected, the piston was burnt up badly and there was very low compression. But hey, it was 20 bucks so I figured it would be some cheap thrills for the tinkering bench. Anyways, a few years have passed and I am finally cracking into it... literally... I tried to get cute and use a couple of screw drivers as a fulcrum to unstick and spin off the clutch. Like an idiot I have cracked the 6-shoe clutch body itself.
Delving deeper into the saw, that is just one more thing I can add to the list of replacement parts that will be needed. Which brings me to my next question - does anyone on this forum have an old SXL-925 of old parts for one? Or know the best place to purchase? Some are available on Leon's website, but others I am having trouble locating (my newly broken clutch being one of them!)
One saw came and went in my area before I could snag it, but wondering if there is a better way to get parts. Seems they are not a super common saw, at least in my neck of the woods.
Cylinder had transfer from the piston, but I was able to clean it up and am pleased with the result. Given that jugs are probably one of the harder parts to get, I thought this rebuilt might still have some potential.
Thank you for your continued help guys!
Jake

Probably going to be mining Ebay for a number of parts. The Chainsaw lady here on this site is a great source to tap into. Seems to be a lot of 5 leg clutch spiders from not using a proper removal/installation tool. Be prepared to bring a couple C-notes to your rebuild party. Best of luck with your project. You have come to the RIGHT place for help.

Welcome to HoH! What parts (other than the clutch spider) are you in need of that you're having difficulty getting?Leon & Joyce are our 2 go -to parts suppliers.If they don't have what you need you'll be directed to go to eBay,which I advise against,unless you like paying way more than the part is worth.I almost always use eBay as a last resort.I have 2 other parts suppliers that might possibly have what you need,but I always suggest you try Leon & Joyce first.

Thanks to you both for the advice and quick relies. Looking at the manual, it appears the spider clutch is a PN:65723-2.
I was also wondering if I can use one of the replacement pistons I have been seeing online in my saw... Reason I hesitate is the burnt up piston is a thin ring. The ones I am seeing (from lil red barn, etc) all seem to be thick ring. Not sure if these are interchangeable or not. I think Homelite produced 925's with both at various points in time, and also had some saws with slightly less power (82cc vs 77cc I think?)
I have a couple photos of the piston that came out of the saw, but not sure how to post them...

There we go. Figured it out.

I think the exhaust port shape differed between the 2 size engines. I believe the larger one use the 2 thinner rings to avoid getting hung up on the exhaust port edges. Someone here will have the definitive answer. Try matching what you have.

The thin ring piston was used with the oval port exhaust. You can use the thick ring piston with the oval port design. The thin ring is not recommended for the bridged exhaust due to the possibility of ring clipping. Also thin ring piston is 82cc. 69644 cyl. by Clasec, on Flickr

Got it. That was my fear. I made a big list of parts needed at one point, but have since lost it... Will need to go back through the saw and probably wince a bunch of times again to re-compile the list of casualties. Thanks again for the help.

Thanks for the info Clasec! Sounds like either piston type will do in my cylinder, if I am understanding you correctly. If I were to get a thick ring piston, would it stay an 82cc saw or drop to a 77cc? I cant imagine the piston style changing the overall displacement, but there is much I dont know. Thank you

Ring style will not change the cc,s The 77cc piston is 2 inch and the 82cc is 2 1/16.

Got it, thank you for the clarification on that.

Welcome to House of Homelite Jake ! Looks like carbon scoring damage caused by ingesting carbon flakes , some of which are still stuck to the piston crown . Overheating was also an issue on these . Please post the UT and Serial numbers from the ID tag if it still on the saw . Thanks !

Hi 5terrysupersaws - I would agree. As I understand it, the overheating issue is the reason decent cylinders are fairly hard to come by for these.
The aluminum from the piston has been scored to the point where it is pressed around the ouside of the rings in some spots, completely retaining them tight to the cylinder and rendering them useless. Someone must have really overheated this one. Luckily, I was able to get the cylinder to a point where it can be salvaged (I hope).
I just went and checked. Unfortunately I don't see a UT or S/N in any of the usual spots on this saw. Let me know if any specific pictures would help. It is fairly disassembled at the moment.
Thanks!

Thick ring pistons for the VI-955, XL-923-924 .. etc, will fit and can be used as replacements in oval exhaust port Super XL-925 cylinders . Leon has both thin-ring and thick-ring NOS pistons in stock . Also has clutch spiders, but I'm not sure if part number suffix makes a difference on the spiders , Without an ID tag it's difficult to establish an exact model and build date . Pictures of the starter and drive-case covers may help somewhat .

Holy cats! That thin ring piston is 100 bucks on Leon's website. I guess I was warned at the beginning of the thread, but that is a bummer. I have sourced things from him before and know his pricing to be extremely fair, so not disputing that one bit. Just a bummer that they are so rare. I will probably look at one of the thick ring options instead. Those seem to be a little cheaper for whatever reason. Would have been nice to keep it as it was, but that is a little steep for my tinkering budget!
I will take a couple photos of the saw and upload shortly. Thanks so much for your help on this.

Here is a photo of some of the components:

Looks like you might just want to use this saw as a parts saw & look for another 925.To replace all those parts is going to cost a mini fortune.

Sorry, I have all the parts for the saw in a bucket. This is just a photo of some of them to hopefully help 5terrysupersaws date it. It looks to me that it might might be a frankenstein to some extent, different parts have slightly different orange/red tints to the paint.
