Hello to one and all,
Yesterday I got my second Homelite 7-29 parts saw, with the 129cc engine. Now I am onto the task of moving the entire engine including crankcase, cylinder and piston and all the parts that are from the 129cc engine to my first 7-29.
I was wondering, is it possible on this particular saw to remove everything from the crankshaft without taking the entire saw apart?
Thanks in advance!

Not a pro when it comes to that series of saw, but I do beleive that the majority of the saw does need to be dissassembled to get to it, iam sure someone with more experiance on these will chime in with more detailed input, good luck

I stumbled upon a problem. The clutch won't come off the second or first saw. Does anybody know if the nut needs to be turned clockwise or counter-clockwise? I've tried many methods, but the clutch nut won't budge.

UPDATE: The nut came off, but the rest underneath won't. Although I used an impact wrench with short, quick bursts to get it off. The actual clutch has nothing to grab onto with a wrench or anything.

On the 7-29 I believe the clutch assembly slides onto the crank shaft & uses a retaining nut to hold in place, since you removed the nut you should be able to slide the clutch off, some penatrating oil may need to be used or a little heat should loosen it up, i always use breakfree let it soak for a while, then add a little heat then a little more penatrating oil.

Good idea. I've got a heat gun, and some 5-56 penetrating oil. Will put that to use. I'll keep y'all updated.

Well I tried heating it. No go. I think because of the size of the saw's engine it's on there pretty hard. I do have a clutch tool, for Poulan that is. Not for Homelite.

Can you post a pic of the clutch

The heat I set it to was 392 degrees Fahrenheit (exactly 200 degrees Celcius in my case.). Maybe increase the temp?

The clutch is keyed onto the shaft with two keys.
A puller is required using bolts into the threaded holes of the clutch spider.
Suggest a flywheel, steering/wheel, etc, type of puller.

This is all I have at hand right now. EDIT: Didn't know the holes had threads until now... feel kind of stupid I didn't check that first. However are there any bolts on the saw that would fit in there? EDIT2: Seems after a little research, like you said, I need a different tool... didn't realize that until now. Attachments:

Here is the puller I use. 10-32 and 12-24 screws cover most of flywheels/spiders with two holes.

If careful, can one use a hammer and something of metal to pry off? EDIT: If it's required, this is all I could find from my local store's website for hardware tools:

That might work, as 5terrysupersaws stated you need the propper threaded screws To thread into the clutch assembly, a few thick washers should work since that seems to use larger bolts, just make sure you thread the locking nut on the crankshaft even with the top threads so you don't damage it.

Alright. I'll give this a try.

THe flywheel and clutch cover on saw 2 are off (the one with the 7-29 engine) the flywheel was in better shape on saw 1, so I'll put that on saw 2.

It done, and complete. Now, I need to figure out how to get it started... it has spark and everything, but it's what I suspect a Torque Monster... with tons of compression for sure! The starter is quite hard to crank.

Is it hard to pull over with the spark plug removed? If so the cord may be binding in the starter pully & new one will solve that problem, try poring a shot of fuel in the carb to help start it, since its a top tank model it should get fuel instantly, check your H&L setting also to make sure there not closed.
