Allis 170 With A Perkins Diesel ( Hard Starting)

KCTractors · Mar 10, 2020

Just purchased a AC 170 with a diesel engine. When it starts, it runs good.
Temperature been in the forty's and this tractor just does not want to start without plugging the block heater in. Plug it in for a half hour and she will start right now.
I have Case 530 CK diesel and it will start right away in the mid twenty's with no help. I started my Ford 6000 diesel today after sitting since October and it fired right up also.
My questions is, are the Perkins 236 engines cold blooded?

It mostly depends on the injectors, injection pump. timing and fuel. Of course you need to have it cranking over fast enough too. Sometimes battery cables need
replaced or connections cleaned up. Compression, valves & rings, can't be sloppy either.

Well, when you're talking a tractor that is 50 yrs old it could be a lot of things. I know them when they were new. They almost needed TWO BATTERIES, but there was no room for that under the hood. You need a 1000 CCA battery, big fat and clean battery cables and a healthy starter. Switching to a 10W-30 motor oil instead of 15W-40 or straight 30 wt helps a lot too. They have to SPIN FAST to start good.

I realize it's not the same, but I have 2 Kubota tractors (B7100 and F2000). Both have glow plugs and both around 2000 hrs. At
40*, neither will start without the glow plugs but the 7100 requires at least 60 secs. while the 2000 will start after 30 secs.
At 90* the 2000 will start without the plugs. The 7100 still requires 30 secs. I bought both tractors used 20+ years ago.
neither uses oil and both seem to have the same power now as they did when I got them. If the battery is good and it wants heat,
give it heat.

Is air filter ok ?
Also could problem be caused by modern low
sulphur fuel?

I have owned a AC175 with a perkins 2.48 since 1981..bought it new. It's been a cold blooded beast since it was new. Anything below 40 degrees and it now struggles a bit. ..It now has 4500+ hours on the meter..but since it's a mechanical hour meter I would have to guess that it probably has at least 7000 hours on it..considering it has been a chore tractor for a number of years now.. lots of low RPM work. However, I've always plugged it in for 15-45 minutes if the temp has been below 35 overnight... Saves a lot of wear and tear on the starter.

I have a new air-cleaner coming. The one in there looks like it should be replaced.

Can only say this, my dad had a 175 with the perkins engine, and it used some oil, but it would start in cold weather before my
185 would, but the 185 had the heater so just plug it in for a few hours and it was good to go. That ole 175 always seemed to
start unless it got down to about 25 or below then it needed some help.

Can't speak for the 236,but the 354s are all over the board. I've got two of them. The one is in an Oliver 1850 but is originally out of a White combine. That thing starts in the teens with only a little help from the manifold heater. The original engine in that tractor was bad in cold weather. I have another one in a White 2-105 and that one's as bad as the original from the 1850.

I have found with hard starting diesels that if you put in a new air filter they become even harder to start, a dirty filter gives a bit richer fuel to air mix ratio. My first Perkins 248
used oil when I bought it, it would start immediately into freezing temperatures. Once it was overhauled it became like the way you describe yours. It really doesn't matter when
you know the engine is essentially in good shape. It's just the convenience factor to have easier starts when the temperatures dip.

I found that if I crank the engine for 5 seconds before turning the fuel on it starts much easier. That takes a good battery!

If it starts that easy plugging it in why not just plug it in and don't worry about it?Makes it easier on the starter and engine anyway.
