Looking for correct part numbers for 044 rebuild

[revving13500]

Hey folks, I've got an 044 from work that needs a top end rebuild. It's an old slant fin so I believe its a 10mm saw. In the parts manual for the 044 they have 2 options for top end parts (im assuming the difference between the 10mm and 12mm models). For the piston and cylinder im seeing and option for 1128 020 1227 and 1128 020 1201. Any insight into which one i need to order would be appreciated.

If it’s a 10 mm saw you’re getting gonna need the 1201 part number. Good luck

I have two 044 chassis' that are slant fin 12mm. So you might need to check if it is actually a 10mm or not

It would be best to first figure out what chassis you have, the pics above in post#6 will help greatly to tell if the crankcase is a 10 mm or 12mm. When it comes down to cylinders it would be best to know if if it has a 10 mm wrist pin , the cylinder from a 12 mm piston pin will fit on the chassis but there is a possibility the ring ends from a 10 mm piston can catch in the exhaust port,only careful layout and measurements can determine for certain. I have a 044 with a 10 m piston running in a 12 mm cylinder ,the ring ends are close to the edge of the exhaust port but I determined it had enough cylinder wall area for the rings to have support even when they wear down to end of service life.Determine what saw you have first and the rest is easy to determine.

Most 044 had the same slant fin cylinder, whether it had a 10 or 12mm pin. Go by the notch/angle in the case by the muffler or by serial number
