1987 418-8 Kohler M18 Magnum

[Brian Mummert 5]

Hi everyone. Just brought home a 418-8 (original owner recently past). Needs some obvious maintenance (sitting for a year, but turned over). The fuel line needs replaced . When replacing, has anyone put a fuel filter on the line.  And if so, where did you put it? I have  a 416-8 K Series and put one on which was easy.   Also, after reading other threads, what oil to put in transmission/gear box?.  Do not operate in winter.  Thanks in advance for thoughts.  Brian M.

That definitely should already have a fuel filter. We don't run any twin cylinders here but have had them around.  The fuel filter was located near the fuel pump close to the battery tray.  

 

Transmission fluid is pretty much any 80W to 90W base with up to 140. These transmissions are tough. Doesn't matter what brand. We use cheap wally world gear oil.

Thanks for your input.  Much appreciated.  Brian M.

A Kohler Magnum Twin with an eight speed is one very strong machine. Since you don't know much about the previous owner's maintenance changing all the fluids and fuel line is a good idea. The fuel pump is located on the top of the engine and if you have to crank it over for a prolonged period to have it start you may want to consider an electric fuel pump located lower than the tank, did wonders for my 418.

@Brian Mummert We are going to need some pictures of your 418!! There’s a few of us here that are big fans of that model, be it the 8-Speed, the A or C. I have an 8-Speed and C.

I will try and get a photo up.  Long way to go for it to look like C-Series Don's tractors.  . Does anyone have a good place to get parts for the M18 Magnum engine? I.e. parts for fuel pump or carburetor if I need to rebuild them?

For rebuilding a carburetor I only use original Kohler parts.

I've been buying from billsplaceshop.com  for a lot of my OE parts. Good luck so far. Prices are phenomenal.

 

As far as parts go, we have several absolutely top shelf sources. There's nothing you can't get for these old tractors.

Did wonders for the KT 19 in my C 195 when I did this.

OEM carburetor parts for the Walbro  are available.        https://www.walbro.com/parts-services/

The needled and seat on a Kohler kit are not compatible with the Walbro. The one on the left is a Kohler, the one on the right is Walbro. If your needle and seat are good you could use the much less expensive Kohler kit.
