@Woodwackr does that saw have a full or half wrap? If it has a plastic tank make sure the front isnt melted through from the exhaust

Yes, wrap handle, chain brake that looks iffy. Let me find the link…

A bit of MMWS6100 action today.

 

[RCBS]

Can anyone confirm part number for Makita clutch tool for 7900? I'm seeing #944-500-570? Dropping a part order and figured it'd be nice to have one.

That seems to be the correct part number.
You are on the right track.

I made my own, I am considering to sell a couple to recoup expenses.


You can cut up a socket and make Your own tool.

Can You tell the man what size socket fits?
I can't seem to recall on top of my head.
Been a while since I last tinkered with clutches on any of my saws.

17 or 19mm?

Edit:
A 19mm socket can be made into a 7900 clutch tool.

 

[Powerstroke Cowboy]

Yup, same. 19mm or 3/4 inch socket if memory servers me correctly. Cut ever other flat off and you've got a socket tool.

There You have it, 19mm socket.

I started similar to that, though not socket type but rather solid steel milled, then went manic and made a much more beefy heavy duty tool.


You'd snap multiple crankshafts before managing to destroy my clutch tool.

I had initially put in for # 944-500-590 and they came back telling me # was invalid. I located this PDF that shows shop tools and found that -570 looks to be correct. Waiting to hear back from order dept.

I googled it and multiple web shops list the 944-500-570 as clutch tool.
Pricey that thing though.

The tool you made is a thing of beauty!

Thank You!

I guess I will have to manufacture one. Was literally told to 'try SawAgain' by Makita tecnical support. He even provided a link. Was trying to score one at dealer cost. Ah well. Still have $200 of parts inbound. Rubber, filters and misc for my saws and other stuff. They still have 20" loops of LGX too so I got a couple.

Wilhelm...if you could only have 3 spare parts for a 7900, which 3 would they be? (most prone to failure/breakage)

 

[heimannm]

clutch, brake handle, muffler

Oil pump drive
Complete clutch set
AV spring set

The above always seems to be compromised on used saw purchases.
I have multiples of these stashed!

Exactly why I asked you. I got some backup AV. Need to get clutch and drive parts next order. Thank you.

 

[RCBS]

clutch, brake handle, muffler

A flag is on my list. Got an extra hollowed out muff already.

 

[RCBS]

Wilhelm and Heimannm, the clutch...do I need to get an xrtra shoe also, or just the guts? (139 or 139 +189)

Get the clutch 139 and a drum 189.

I go with the logic that the clutch is a set and should be replaced as such.

I have been told that the drum hub is prone to separation from the drum, although I never had that happen myself.

Get a couple spare E-clips 146, they randomly open black holes and vanish in them!

 

[Wilhelm]

Those clutch parts were dirt cheap not too long ago.
Same with the AV mount sets.

Not anymore...
