My XL 113 lost a piece of reed valve, about 1/4" x 3/4" - I've been fishing around down in the crankcase with every sort of magnet I have, but haven't found it. If it's not in there, where else, as it didn't come out through the carb or into the head. Any ideas?

Personally I would tear it down. My guess is its lodged somewhere in the crankcase. Tearing a saw down takes what, 2hrs maximum, if you leave it you run the risk of an engine failure. You dont leave a particle in there of that size without running the major risk of an engine failure, imo. i guess i like to go by the better safe than sorry idea, as it sits now your repair will be inexpensive (cost of reeds) adn the time to make sure the engine is clear of the reed. but if that part causes engine failure you are looking at a much greater cost. To me id rather lose some time finding out for sure the saw will be ok than potentially having to spend the money (and time) to fix it later. my 2 cents anyways.

Yes, and I knew that too - It's too stinkin' cold today, so i'll be at the bench. Let you know if I found it - Thanks - Well, tore it down, haven't found it yet - Maybe a feeler guage along side the c.s. counter weights? Have to try that later. Question - How much slop in the c.s./rod/piston is normal? Mine seems really, really lose.

side to side play, or radial (perpendicular to the crank)??

If it were me , I would not want to tear it down. I would try everything under the sun to get the reed out. But if that failed I
I definitely tear it down:(
It stinks that something so small can be such a pain in the rear.
Good luck. CSW

Mike, that doesn't sound good. Pretty sure all the XL-1xx series had a ball bearing on the clutch side that's held on the crank by a C clip and bolted over to secure it in the crankcase. If you're getting side to side play, my guess is the bearing's gone. I don't have spec books with me, but from memory I think these should be pretty tight.

mike,
is your crank able to move side to side, or just the rod on the crank? The rod should have some side to side movement and it will be more than you would think, at least thats how my saws have been (hope thats normal ;D) However, if the crank itself moves side to side in the crankcase you have issues that need attention (new bearings/seals etc)

The crankshaft is nice & snug, I had to go to a really fine feeler gauge to slide down beside the counterweights looking for the missing reed part. Never did find it either! I put it all back together, heads back on, etc. At least I know there's nothing in the c.c. The piston & cyl. wall show wear, not scored, but some carbon, etc. I cleaned everything up, we'll see what happens when the new reeds come. I'm probably not the first to think of this, but to hold 30 needle bearings in the rod & cap while you put it back together - A nice layer of grease works ! The cly. fins were really packed with oily sawdust, so thats clean too. At least I know that if see blows someday, it'll need a rod, piston, & cylinder - If it's worth all that. Time will tell.

Good deal Mike. I thought you were saying there was movement in the crank. My misunderstanding. Hopefully the missing reed will simply stay missing and out of any future mischief making.

O.K., here's my last 'tip of the day' If you lose the decomp pin from your XL113, don't spend more than an hour looking for it with a magnet  It's made of stainless, and you may as well use a corn cob as a magnet  |

There are many grades of stainless and depending on what's in it, it may have very low magnetic properties. I took a magnet around the house and workshop and tried it on stainless things and could feel the difference. The most noticeable item for not being magnetic was the stainless steel kitchen sink - the magnet didn't stick. Reed valves are quite thin to start with and that would mean less iron so maybe that also has some bearing. At work, the developer unit in our printers use quite strong magnets and none of the stainless steel screws used in this area will stick to my magnetic tip screwdriver.

Got the new reeds in this saw last night, but too dark to go try it out. This AM, got out on the 'pile' with it - Boy, runs like a Swiss watch! I guess the play in the c.s. bearings is a non issue [for now anyway] There was a lot of carbon on the piston head, even in the ring groove, which I took off & cleaned. I ran a tank + of gas through it, sawing 16" maple logs up, with a 2/3 gone semi-chisel chain. Gotta say I'm glad I tore it apart, got all the trash out of the fins [used to smoke when it got hot] Saved another old saw from the parts pile  |

I've always felt the XL-1xx saws were a nice design. I don't know why Homelite dropped it but every one is worth the effort to keep it running |
