My experiance with Homelite 45 conversion
I just finished taking apart a Homelite Chain saw to convert the thing for my Zirolli 1/7 p47 and I thought I would drop a note to let you know a few of the kinks that I ran into.
First you need to get the clutch assembly off the thing to get it out of the case, do not unbolt the 4 bottom bolts that hold the saw to the case. You need them to stay in util you get the clutch off, if you take them out early the bottom will come loose when you are removing the clutch. Ok, on the clutch take the clutch drum off first, this is a half moon clip that holds it on, no big deal the thing just slides off. Next remove the chain brake strap and take a pare of wire cutter and cut the spring that is in there, it will get in the way. Next take out the spark plug and rotate the engine until the piston is at the bottom. Take some soft rope and push it down into the cylinder until you fill the whole thing up with the rope. Why did you do this? Now when you put a wrench on the clutch assembly the piston will only go up until it hits the rope. Do not try to jam a screw driver into the flywheel you will break of fins. Ok next look at the clutch. You will see and arrow stamped on it with the words off stamped in the metal. You will notice the clutch unscrews counter clockwise not clockwise. I found that a good pair of large vice grips worked the best. I just put it on the floor, put my foot on top of the cylinder head and pulled and it came right off.
Now that you have the clutch off you can take the bottom bolts out of the case disconnect your carb and wires and remove the saw from the case.
The next wrinkle it cutting off the shaft. The 45 has a free spinning worm gear on the rear shaft. The pictures that I have seen on this conversion do not mention this little jem. I first tried a gear puller but to no avail. So what I did is take my handy cutter and cut the shat off almost to the back of this oiler worm gear. I left about a 1/8 piece of it still on. I then took my Dremel tool and split the last 1/8 that was left and was able to pop it off. when you are cutting this thing off you will need to keep it from spinning while you are cutting. I used a pair of forceps to keep it from turning.
The final thing is the riser block that the carb bolts to has lots of extra plastic that was there for the chain saw air filter to bolt to. take your band saw and cut all that crap off. If you don't it will block the throttle linkage.
Hope this helps someone
