MCCULLOCH The official McCulloch thread

[edju1958]

Today started out good,I got the chain brake on the PM 10-10,then moved on to putting a baffle in a 10-10A (sounds much better now).Next on the list way putting a new starter handle on the 1-70,then it went downhill from there.I attempted to put the recoil on the 1-75.I got it on OK,but when I pulled on the handle to try to start the saw the handle & rope wouldn't retract.I also noticed that the pawls are all screwed up.I took 2 turns off the spring & it still isn't right.

Well gents, it looks like trips to the attic will be off the menu for a bit.



Ed - the 600 Series saws have an additional boss on the brake cover that prohibits pulling the brake handle into position like the 10 Series. The basic process is similar but the boss on the 600 cover makes the job more difficult, as you say the spring wants to jump off the latch. I took a piece of 1/4" rod and drilled a hole in the end that just fits over the spring, then I can use that as a lever to wind the spring far enough to press the brake handle into position. It makes the job a lot easier. I'd take some photos but all my spare covers are in the attic...

What happened there Mark?I see you with a cane.I thought I was the only guy who used a cane from time to time.
Very clever on the homemade tool for the winding of that little devil spring!

Can't like that post! What happened?

 

[heimannm]

Landed wrong...

Here's the offending boss on the 600 Series clutch cover.



And here is the tool I made to help me get that spring in position.



With the tool I can wind the spring far enough to position the handle past the boss and press the handle into place.

Landed wrong? You know your not supposed to be leaving the ground in a way you have to "land"?

Well I don't feel so all alone now .About a week ago I slipped on a throw rug and collided with an internal brick wall with my old noggin .Then day before last did it again tripping over a power cord plus a big hosta plant while working on my propane line for the new furnace outside ..Good thing I have a head like a buffalo .

Yikes. Be careful Al.

I hope your recovery is speedy.

I think I found out what's wrong with the clutch end of the starter on my 1-75.I pulled the clutch off today because the pawls will lift up a good 1/4 in.from where they seat.It seems whoever the intelligent "person" was who took it off & replaced whatever ended up deletying the rivet sleeves (kinda like a washer), Now I have to figure out how to take the clutch apart to replace what's missing.Dumb asses.

 

[edju1958]

I'm trying to figure out ow the 1-75 clutch comes apart.It looks to me like on the backside there's a "plate" that unscrews & allows one to separate the spider from the shoes.The thing is - which way does the plate unscrew,RH or LH?

Careful Ed, you have your address clearly in your pics.

Don't worry, most of us have mailed terrible projects to Ed already!

That's right,Lol.It doesn't bother me that my address showed up on a pic I posted.If someone wanted to find out where I live all they have to do is Google my name & presto.

That plate does not come off. To replace the spring or shoes you have to stretch the spring out and work the spring out, vise versa to put it back together. It helps to have special tools when it's time to reassemble.

Thanks Tim - much better today than it was yesterday. The immobilizer really helped a lot, stairs and the ladder to the attic will be a challenge for a while.

Us older guys always seem to get some nasty lessons along the way. Take care of yourself and take it easy while you recover.

So I can't replace the rivets then & put in rivet sleeves without those special tools to take the clutch apart?

 

[edju1958]

I'm pretty sure I found the problem with the recoil.I took it all apart again & of course the spring had to hang onto the drum & go flying.No big deal,they're easy to put back in.Anyway,I left the outer cover off & pulled it over.The drum wobbled worse than a smashed up bicycle in a cartoon.I'd say it's time for a new drum (part # 55871).I found one on Feebay for $12 or MO.I'm waiting to hear back from the seller.

 

[heimannm]

Ed - That is a tool that someone made, it was passed on to me. It is possible to disassemble those clutches, but it is not an easy task and normally requires more that two hands. You have to pull the shoes out and at the same time slip the spring in or out of the groove.
