Re: Max28 and cold Weather, Dealer report.
I sent dealer an e-mail regarding troubleshooting my Max28.
He cal em this morning.
In my past reviews of my mew Max28 in this forum, I remarked that for a new motor, it always smoked and stumbled more on start-up than my 32 year old tractor.
I mentioned to the dealer that waiting a few minutes to restart often did the trick to get it started and expressed my doubts that it was a glow plug issue or GP relay, cranking speed issue, or due to thick lubricants.
Service manager personally reinspected fuel starting solenoid, verifying it was set to spec, still no start.
He then opened it up another 1/4 turn, and it started in 17 F weather.
He is going out this morning after it warms up a bit and fiddle some more with it.
He said backing it out too much will cause motor the stumble and stall. He will find that point and then adjust by observation where the motor runs best.
So I hope the issue was the engine was not getting fuel.
I plan on bringing it home Saturday.
I appreciate the efforts by the dealer, as I bought the tractor in NY state as no Max28s locally were still available and the Max 26 was near $2000 more, so it is not like I gave the local dealer any business.
I think I need to buy a few filters.
PS the Mitsubishi motor comes with an electric fuel pump to help with priming and gravity fuel delivery.
Many other fuel injection pumps have a mechanical primer built in.
