 Topic: 185 Hard starting
Posted: 14 Mar 2017 at 11:57pm |
|
I bought a 185 last fall and used it all fall on an auger. It was pretty hard starting when it got colder even plugged in I had to use ether on it. This winter I rebuilt the engine in it because it had blowby and slobbered oil. Had the head magnafluxed and planed. The pump and injectors were supposed to have been rebuilt before I got it and it does have a diesel shops tag on the pump. It still doesn't like to start. This is my only 301 but I've never had a 426 this cold blooded. Once it starts it puffs white smoke for a long time before it comes out of it. I'm thinking about adding a intake heater and unhooking the ether. Any suggestions?

I have a 185, and yes mine is hard to start cold, but I plug in the block heater and it starts right off, hardly have to let it crank. But if you try to cold start it, either and a lot of cranking may get it started.

Might want to check the block heater. Sounds like it is still cold.

That could be true, I had to replace mine about 5 years ago, the cord shorted out. The Agco store still had replacement block heater when I bought mine.

I put a new block heater and cord on it from Agco when I bought it. I haven't plugged it in yet since I rebuilt it, but being in the 60's here lately is when I tried starting it. My 7060 started up no ether. Does the intake heater make a lot of difference? A guy told me the other day his 190xt is their best starting tractor when using it.

Old valves were re-ground and re-used, Yes?? So, that means the old cylinder head seats were re-ground as well?? This will lower the cranking compression a bit....grinding valves and seats on a hard starting engine can add to the problem. New valves and new seats machined to the minimum valve recession spec is best. Retarding pump timing a couple degrees will help. Lowering injector pressures from 3450 to 2900 will help too.

Ran into this a few years ago, guy had a 185 complained how hard starting, tried everything you did, still hard to start, white smoke etc. The problem with that one was he had a John Deere mechanic take the pump off for rebuilding etc, he timed it like a John Deere at top dead center, once I changed the timing to where Allis Chalmers wanted it, it started like a champ .

Yes I did have the old valves touched up when they checked the head. Cylinder #1 ate a compression ring, but the valve and seat didn't look too bad he said. The previous owner fed it ether as there were 5 empty cans in the cab, but I really hate using that stuff. I never thought about the timing being off since they had the pump off getting rebuilt.

185 should start pretty easy in the cold especially when using a block heater. I thinking the injector timing is off.
Our 180 and 185 are the easiest cold start tractors of them all. If it under 15° we plug in. Other than that we use the glow plugs.

I just bought a 200 diesel last year.
It does not like cold weather. I put on
a tank heater replacement from previous
owner. I plug in heater for 20 to 30 minutes
and it starts right away. I do not like to use
ether.
