Ck20HST cold starting procedure

[jabelding]

I have one in my ck35 I got sick of the acid spilling out of the cheap piece of crap the dealer put in my tractor. I had to completely repaint the battery area on a 1year old tractor with 80 hours. Love the optima red tops it will last you twice as long and you probably wont need a battery tender on it they have a much lower sitting discharge rate.

If that were true that they last twice as long I would have one. But I seriously doubt they would do any better for me at nearly double the price.
I got 11 years from my original tractor acid battery. (never leaked), Never had a tender on it
The current acid battery in my pickup is 11 years old and still going strong.

... Will crank and tend to run down battery before starting. If I let it sit for 20 minutes after trying to start it and recharging battery I can get it to fire up.....

I guess the words "will crank" threw me.. The temperature of the compressed air (in the prechamber) is what ignites the atomized Diesel fuel. If the engine does not crank fast enough too much air escapes past the piston rings and too much heat is lost to the cold metal prechamber. Cold makes both problems worse, not to mention colder intake air to start with. Also, misadjusted valves can make cold starts harder (or impossible). On other Diesels I've worked with, the valves are the "tightest" when cold and get looser when hot. Multiple glow cycles (before cranking) are the easiest way to warm the prechamber.
