McCulloch Chain Saws

[Brian Thacker]

I started out running an orange (262XP) saw until the chain adjustment screw decided to take a hike. I switched to a Pro 10-10 and ran 3 tanks out of it. Then finished up some small stuff with a Power Mac 6. Very good day. A lot of wood moved today. The kids were good.

Back a page to Poge's question...I was able to get mine out with a sharp pick starting under one end. I didn't have to worry about the piston or the clips because they were not going to be reused.

If anyone needs a NOS 70 cc piston and cylinder I have one in the trading post. I'll gladly cut a deal if one of the regulars from this thread wants to buy it.

You have my interest but I have been buying a lot of old car parts and have exhausted my saw funds.

Well check back as your fund rebuilds itself as it's still for sale.

I just was given a McCulloch 3-25. It is the single button version. It is missing the air filter cover and the shroud around the spark plug as far as I can tell. It has a 25" engraved McCulloch bar. Is anyone in need of any parts?

maybe interested in bar. pics if it's goin away?

McCulloch bar pics. It's a pretty cool bar. I would actually like to keep it as a keepsake, but another part of me say it should be on a 3-25 where it belongs. If you don't have a 3-25, please don't ask me to sell it to you. If anyone is going to hang this on a wall, it will be me lol. Notice the logo is upside-down when you spin the bar around to the opposite side.

This bar had a .500" chain on it, and the groove measures .063 - .065 in various spots, and the bar is straight.

I pick up a Pro Mac 10-10. The chain brake spring is doing nothing. I did find one old thread but the pics are gone due to the hack. Sorry, I'm sure there is another post somewhere on how to reassemble the chain brake but could not find. What puts the tension on the spring? I'm assuming the top left end of the spring goes in the catch but have no idea about the strait end. If it is tensioned on the handle pin this is going to be fun.....
I do not know the saw - Here's what I have just in case something is broke or incorrect.

Mark, I'll give it a shot. First, grasp how it works. The flat prong of the spring fits against the handle and the bent prong fits in the trigger of the chain brake. Second, have all parts in reach. Next take it as shown in your picture, position the bent prong in the trigger. With the handle at 3:00 place the "pin" under the spring. With an outward tilt rotate the handle upward until the pin is across from the brake band. Slide the pin through the band. Install washer and screw. Then pray the spring remains on the trigger. Note the spring will center itself once you slide the pin over the band.

PS. I see that the spring is already properly in place on the trigger.

A couple of pics may help as well.

Inner spring leg, behind brake band



Outer spring leg

Thanks guys. I was eventually able to get it completely in place with the bent up part of the spring tuck on top of the trigger against the stud for the brake spring. Grabbed a thin wall 1/4 socket put it over the bent up part of the spring an maneuvered it in place.

Latest estate sale find. Quick clean up after I got the chain brake functional.

Tim, your pictures seem to be of a different model and with a better designed trigger but same principles. Now that I am home here are some shots for Mark with his type of trigger. Ron

Mark, very nice find. I have one of those apart right now. Really nice saws. Brian

I'll have to look a the others to see if I have anything different. Regardless, pretty good brake systems compared to the early stuff the other manufacturers had

You pics are great! Maybe someone else will be able to use for their chain brake project.

This is Ron's one pic turned upright showing where the spring is tensioned underneath.
