Stihl MS194t Problems...

[lone wolf]

Ah, so the saws are just the newer models of the previous ones? It seems to me that the differences are mainly the engine size (cc, piston etc...).

The intake manifold that was on the saw, as well as the body points to it being a MS192T, however it has a ms194t side cover on it and I can't manage to decipher the serial number. To me it looks like 3897x0x6x. x is what i can't decipher...

IDK hard to tell from where I am. The side cove certainly could have been switched.

I discovered the 193,4 muffler won't work on a 192.

I looked up the pan. Not available separately in the US even though it is shown with a part number. Your number looks correct for 193/4.
So the question is, do you really have a 194? Or is the pan correct.
Time for pictures!

This is interesting. If i indeed have a MS192T, then I purchased a MS194t gasket from my local stihl dealer, thinking that this was a 194. I came home, discovered that the pan doesn't fit however the exhaust gasket is the same. It fits the screw holes and covers the same area.

Will get some pictures and post them later today!

My pan is on the right side, with the cracked corner. The left side pan is the one I got for free from my local stihl dealer (also second hand, but no cracks)

Key differences:
Different distance between screw holes
Holes for screws are "sunk" into the metal for the one on the left
One on the left has dividers/fins on the inside, the one on the right does not!
Rounded corners vs "indented" corners

Part numbers:
Left pan: 1137 021 2503 (Fits 192/194)
Right pan: 1137 021 2500 (Fits 194)

I have 2 192s in a box waiting for reassembly. Both motors have the 2500
These are definitely 192s

I think so... It's just odd that it has a 194t cover on the side. It has the black tab and everything. They must be cross compatible or something. The intake boot and engine point to it being a 192t, however I can't verify because I can't read the serial number...

Pic of the muffler? That will tell.

That's a 192 muffler.
The fatter one is for 193,94

 

[Bludenz]

Ah awesome - thanks for your help. Do you know if the 192t/194t side covers (flywheel side) are interchangeable? From my google searches they look very similar - same amount of holes and shape, same screw positions etc... however the 194t has a black tab - the 192t cover does not.

My saw is currently wearing the 194t side cover as that's what it came with, has the black tab, the 194t badge, etc...

Check for a number. 609A is 193,4
601 is 192.
As for the motor base, Stihl numbers change up, not down for newer versions. So, a 2500 is for an earlier saw than a 2503.

Where would this number be?

 

[singinwoodwackr]

They should, if, you use the 192 muffler. A 193 muffler won't allow the side cover to fit.
I just went through this discovery
Ordered the wrong muffler

192

193 above

 

[Bludenz]

My muffler reads 1137 /01C - so 192 muffler, right?

Correct, and, a newer version then my 'B'
