Yanmar 186d cold start

[Neat 1500]

I run ATF im my powershift and it performs beautifully, but I don't get those cold temps you guys do...

Another thing that will help a cold weather start is leave a trickle charger on it overnight. The battery will be warmer and it will put out a lot more amperage.

Thanks for all the info! Going out again this morning for another start and will see how long it takes.

My hour meter/ tach did not work when I bought it. Everything is connected all fuses are good. Anyone one had this problem?

The tach is all mechanical - a cable from the front of the engine revolves within a sheath. In the instrument the hourmeter is geared, while a magnet revolves within a cup that has the rpm pointer attached. (or at least that's how a Lucas tach was that I disassembled off an old British motorcycle.) The Yanmar tach is a sealed unit, opening it is similar to using a canopener on a tin can, so only an instrument repair tech could re-seal it for you if you opened it up. And there is so little space under the dashboard that its difficult to detach the upper end of the drive cable from the back of the tach, or detach the tach from the dashboard. If it were me I would ignore this for now, or at least not go beyond verifying that the upper end of the cable revolves when the engine is running.

But I repaired a screechy, jumpy tach on the first YM186D, the one I sold recently. I took the instrument out, turned it face down, and squirted a little lock fluid (graphite in solvent) in around the fitting that is driven by the cable. In five years the problem never returned. I assume something was causing the needle's cup to drag on the magnet.

She started right up this first crank. It was 29 degrees out. Just give me one good snow storm so I can plow once and it melt the next day.

There is a ton of useful information in the old posts here. Well worth some reading time. I seem to recall someone saying they switched to amsoil and it cures the transmission hydraulic winter slowness. I don't remember which oil they used but it is back there some place.

Lots of info I have been reading. It took mine 10 mins. The hitch and left and right of plow work almost right away. The up and down of the plow takes the longest

If you ever want to add a block heater, this is the one I put in my 187d. It was about as difficult as changing a light bulb to install, although some have reported difficulty getting the frost plug to turn.
