More cranking power for the MF10 DIESEL, group 51 battery swap
Posted December 04, 2011 - 12:36 AM
The mowing and sweeping got finished right before Thanksgiving, so the tractor finally had down time. I barely was able to rework the new tower to make the Group 51 optima yellow top fit, the tray had to move up exactly 3/4" to miss the starter solenoid. The terminals are close to the hood so it got a rubber insulator on the bottom of the hood by the battery just in case. I also gave it 4 Gauge automotive battery cables. There were a few other engineering issues I chose to address while it was apart since it is essentially a prototype going through R&D.
It is really, really packed under the hood now. Its as tight as a new FWD cadillac under that hood. I'll have to post up some pics later. Hopefully, the jumper cables will see less use this winter.

The Optimas (AGM type) battery is designed for high amp output, starting current, you should have no trouble with that battery.
The best part was the $60 price tag, a honda mechanic friend of mine had 2 of them, I should have bought both.
Tonight I drove it outside for the first test start and let it set for 2-3 hours while I did some maintnence on one of the cars. It started up with a 35 degree block temperature on the second crank with only the charge air heater. It did run along with the starter for a few seconds but being a one lung diesel its probably a miracle it starts at all cold. This was without the help of ether, or engine block / fuel tank heaters. Lots of heavy white smoke but it started without a jump. For a direct injected diesel with 33 degrees of base timing thats pretty darn good. Timing specs like that are for high RPM diesel competition engines!
Starting this thing cold reminds me alot of starting an old John Deere 820 Diesel in below freezing temps, it sounds alot like one too.

I agree with you on the sound. My LT-1 sounds very much like an old R John Deere when idling. Just can't help but smile when I listen to it. I don't know if yours has the oil injection port for cold starting or not but after 2 years I used mine for the first time the other day and it did help with the cold starting. Sure smoked up the building though.
The Lister Petter AC1 does have the oil port. The government manual I have it says to fill it on start up at 55 degrees, and at 32 give it two shots. I assume it is for the valve train, but it doesn't really say. I haven't really used it unless its 32 or less, I will start doing it at 55 from now on. If course now I can actually crank it over at a decent speed without a jump start. Before the air heater pulled the LG battery down enough that it cranked slow
Here are those pics, it's pretty tight under there.

I had to label some of my fuel tanks also. I could just see someone trying to help and refueling with gasoline.
