McCulloch Chain Saws

[heimannm]

I cleaned up and put this PM650 together last week. 150 PSI compression and runs nicely once I plugged the high speed governor.



It was about as dirty inside as any saw I have opened up.



I like to give them a thorough cleaning and inspection if I am going to put them up for sale.



When pressure testing the crankcase the PTO side seal and crankcase joint were leaking so let's go all the way. Since the thin rings are scarce and compression was over 150 PSI I just cleaned everything up a bit and put it back together. Always a good idea to replace the oil pick up line when you have them down this far.



Dirko HT has become my favorite sealer.

Mike Acres site has them listed at gear reduction drive but they are indeed direct. Mike also reports it is a model airplane engine. 1.4 In3 or 22 cc.

Wow mark. Cleaned up great! I hope it makes friends in the museum. I know its in the right place.

I have converted 3 large frame saws to .375. All where the tapered crankshaft variety. Two of them I used an Oregon drum. When I did the third I couldn't find an Oregon drum but Lil Red Barn sells a drum that worked just fine.

This. Did this with my super 250 and the Lil Red Barn clutch setup, and put a TsuMura lightweight 24" bar on (had to file the stud slot a little bit as it was meant for a smaller mount (D176 but TsuMura typically lists them as "Echo").

Dirko HT has become my favorite sealer.

May I ask why?

 

[heimannm]

Mostly because Dirko HT is easier to clean up than Threebond. Especially so if you have to take things apart again...

Thanks, I was wondering.

I may have won the award for nastiest saw ever today. Surprisingly the jug didn't look terrible... look to bad....

 

[vinnywv]

Wow. I think you win! Thats a mess.

The PM650 all back together in running order. I swapped the clutch cover/brake assembly since the saw was missing several pieces as it came to me. I like the flag style brake handle better anyway. I still need to find a plug for the flywheel cover where the wrap around brake handle pivot would go.

Buried in a manure pile Max?

Some would claim that is where all of the 600 Series should be but I don't have any trouble selling them.

It was a mess! The things a guy will do for a coil and flywheel lol. Believe it or not, I only broke one bolt in taking it down. And I got that one out.

Last June I swapped out the wrap around set up on my 1st version 610 for a later NOS flag style,looked in my bolt cans,found a short machine bolt with matching threads to fill the hole from that shoulder bolt.Am keeping my late 70's 650 all original for the time being,even though I prefer the flag style for obvious reasons.

Some how I missed that aircraft engine powered LH saw discussion until now (cleaned up nice and very unique).

For a while thought this could be fun (except for the long snout on the output shaft and $$$)...

Kevin,so sorry to hear of the loss of your dad.I especially remember the video you posted a couple yrs.ago where you & your dad were taking down a tree & he was explaining to you how to do it properly.Your wife didn't know that & was doing the filming & was getting quite impatient.At least he got to pass on invaluable knowledge to his son.
Glad to hear you finally got that Super 250 running right.As for the grey sand-like substance in the fuel filter,I'd have to say it's fine magnesium particles from the fuel tank.This might be attributed to the additives that are being put in our gasolines today.

Let me add fellas that found a gray substance repetitively in a saw carb and it turned out to be an old piece of fuel I hadn't seen stuck in the tank. When I finally found it and dug it out, it turned to paste in my fingers. The same gray I had found in the inlet screen. No more issues after removing it. Edju is likely right but just thought I'd mention this in case.
Also quite sorry to hear of your loss friend. Lost my dad a while back and it is tough for sure!

 

[heimannm]

Matt - I thought about hanging a bar on the BP-399T but that would be a much larger LH saw.

Dirko HT has become my favorite sealer.

May I ask why?

It is an exceptional high-temp (HT) silicon-based sealer for a variety of surface types that never hardens. It has a very friendly working time. It can often be applied to only one mating surface and needs no setup time prior to assembly. It can be put into use immediately upon application/assembly in most instances including short blocks and cylinder gasket deletes. An application can even ocassionally be reused under certain circumstances where disassembly/reassembly is required. It is fuel/oil resistant. Has an almost indefinite shelf life by simply applying a glob of Vaseline in the cap for storage -- (which works for many types of sealants, btw). I'm going on a couple years with my current 90g tube.

It became known as a Stihl product (which it isn't) due to their extensive use of it and reference/recommendation in many of their products -- particularly for their clamshell engines. The brand wars crowd seems to turn their noses up at it for that reason alone, even though it's actually made by Elring, another German company, and has been used in the Euro auto industry for decades. It was also thought to be excessively pricey as a Stihl product -- which everything is from them -- though it retails for about the same price as the other popular choices.

My favorite sealer as well. Highly recommended.

Good bit of learning there.

No time for stihl except their chain. Love that chain
