Hello Guys, my name is Andy from Germany. Sorry for my bad english but i will try. I want to rebuild my small chainsaw Homelite xl. I dismount and cleaned the motor and today i want to set it together but the question is? When I put the piston and crankshaft into the Zylinder should i adjust some space between the parts or should i press the parts togehter in the way to the crankshaft? Look at th  e picture  |

Welcome Andy,
Can you post the UT for that saw? With that, someone here could post a parts list and be able to look up the service procedures and tolerances.
That said, the XL is not my area really but it looks to me like the "bronze spacers" in your photo are thrust washers. They would control the end play of the crank and should be replaced if the play is too large.
Your English is better than some guys I know, don't worry about it. :{)

ok thanks. :-)
What's the meaning for UT ?
I do some measurements. I put the Crankshaft 1 time foreward and 1 time backward to the aluminium cover and i get 1,7mm space between the thrust washers and the crankshaft.

This is from a manual stored on my phone. I can get a better copy if needed when I get home.  |

Looks like sawnami has what you need.
UT number is unit number that should be on a tag on the saw. Depending on the year of manufacture, it could be with a serial number or other data, all of which can be important when trying to find the right parts list or procedures for an individual saw.
Best of luck.

Sawnami, correct me if I am wrong. It looks like the .015"/,38mm shims go between the thrust washers and the bearings, the bearings and seals get pushed toward the center to take up the end play in the shaft. Then without moving anything, the shims are pulled out and the bottom of the crankcase is installed, clamping the bearings and seals in place. When done the crankshaft should have .030"/,76mm end play. Does that sound right to everyone?

the thrust washer looks a little bit like this. thats why i'm asking. you see it on the first picture
the shims in the scetch look like a *U* but i think for the shaft.
ok the result is the green arrow and on both site's like on the picture.

It looks to me like you have it Andy, the shim looks to me like a "U" that fits over the shaft between the bearing and the thrust washer.
Is the blue arrow pointing to the shoulder on the thrust washer, which really is not as pronounced as in the sketch? In your photograph it looks like the shoulder of the bottom washer is roughly the same OD as the bearing, is that about right?

yes the shoulder on the thrust washer is nearly the same OD like on the bearing.

Just because you sent the S/N, your saw was built on October 14, 1980, early in the morning. 7 is the assembly plant (I don't know how to decode the plant), 0 is 1980, 288th day is Oct 14, 0038 is not too many saws after the start of the day (this is the actual serial number and is often in the many hundreds).
