In all the banter that has floated around about this saw ... Lee's silence is deafening.

He must be scrambling for the MA GTG

Well, here's a good starting point: "I'm working on my next twenty."

When I was assembling my 6800i, I noticed that the older 120si had that metal oil pump gear. I almost wish I would have pulled it to put on the 6800i so I never have to worry about a bad oil pump worm gear. I decided against it ultimatly but I'm sure you could try using heat to heat both the crank and the worm and them cooling the crank with ice cubs and then pullin it.

I use a small Posi-lock 2 jaw puller. The pump you speak of (nylon gear) also came on latter 116/120si.

It is called an 'eco oiler' it only pumps when the clutch is engaged and spinning since it drives off the splines on the drum.

I have several with the nylon gear and have seen no failures. One good thing about Makita, since they took over many parts are still available.

Haven't checked but I bet you can still get them.

Not really a Sachs Dolmar, but it is a SD design,

Horizontal crank play

I was told to post this over here to see what you guys thought.

A friend of mine wanted me to tune up and go through his saw. In doing so I felt for play in the crank, vertically it was tight but horizontally I could move it back and forth about .036 to .038.

I have never seen this before. Could that saw have spun the crank bearings?
I have not split the cases but the bearings feel good.

Thanks for the help.

We need to know the model of the saw just in case it uses needle bearings, if so they can have a lot more lateral movement than ball bearings.

I sent him over.
It's a Sachs Dolmar 111. He believes it's low use. compression 165 lbs

 

[pioneerguy600]

Some of those smaller SD saws did use needle/roller bearings. Not 100% shure the 111 did but very likely if the crank has that much lateral movement.

IPL for the smaller SD saws,

Hey thanks guys!! Yeah the saw is really low hour, the P/C look perfect and the saw looks new.

So that IPL says its a standard roller bearing, not a needle roller bearing right?

I hate to split the cases just to take a peek? Oh and would you guys know what the parts availability on that saw would be? Just used or is there some new stuff floating around still?

There is actually two different sets of bearings in the IPL`s , both roller and ball bearings are shown and listed. Check page 2 and find # 35 and 36, they are listed as roller bearings.

That description in the IPL is hard for me to make sense of.

So do you think that crank movement is normal or something that needs attention?

Did you actually measure that much runout with a dial indicator?

 

[fossil]

Just curious. Do the radial ring positions set the end play in the crank?

On a ballbearing equipped saw, that`s a yes. On most roller/needlebearing setups there is usually thrust washers used to set/limit the lateral movement.

No I didnt use a dial indicator. I used my calipers to measure the horizontal movement.

Where's the love for the old SDs?

Just checkin' eh?

Here is another old Dolly. Picked up this Mac SP 85 (133 Super) the other day. I have five of these yellow Dolmars now and this one is in really nice condition. The compression is quite extraordinary. Should clean up very nicely.
This is the first SP 85 I have seen in the flesh - they are quite rare around here, though I believe Gmax has one.
