5225 starting symptom

[CAB/AIR5225]

Maybe this is normal...maybe not. I have an 06' 5225 cab/air 5 cyl. On a cold start, be it 20 degrees or 60 degrees, at first crank, it starts at once, sputtering, and smoking for about 5 seconds...then cleans out and purrs like a kitten. My other 3 cyl 5203 NEVER smoked or sputtered on startup. The 5225 has about 295 hours on it and I have had it about 200 of those hours. It stays in the shop, out of the elements, just did the 300 hour service, still does it. whatchathink....normal or not?

Intake heater or glow plug faulty ?

 

[CAB/AIR5225]

I have no idea....one in every 10 cold starts, the white smoke wont go away, until you stop it,,,then restart. gone. Other than that, it runs great, has never stalled, I use conditioner at every fillup. Our diesel here is only 500 ppm sulpher, so I use Service Plus.

If it had 2000 hrs on it I would suspect leaking injector when shut off. Under 300 hrs I don't know, I would not think you would have a bad one already. I would ask the service mgr the next time you are at the dealer what he thinks.


My shot in the dark guess: injector or injectors are bad

That's pretty much how my 5225 starts too. I figured it was normal. Mine only has about 60 hours, so I really don't think anything is wrong.

 

[CAB/AIR5225]

Husky....I am going to post a short video of a cold start at 1/4 throttle tonight, and we can see if we have the same problem and/or normal start up condition.

 

[81husky]

Mine has never done the white smoke that you describe, but it usually blubbers a bit with black smoke and then clears out. Takes 3-4 seconds at most. When it's below 30 degrees, I try to plug it in for an hour or so, and that helps. Running the glow plugs for 10-15 seconds makes a difference too. I'll check out your video.

 

[CAB/AIR5225]

Well..... I went to record a video. I am sure I set the throttle a little more than I normaly do. The ambient temp was about 60 degrees. It smoked for a short 2 or 3 seconds, cleaned out and purred. Not what I have been seeing. Maybe I just need to set the throttle up a bit more. I used to start it at idle. I am going to try a few more cold starts at 1/3rd throttle and see how the new few starts turn out. I will let you know. Maybe setting the throttle at 1/3before starting helps to blow out whatever fuel is setting in the intake/combustion chamber. We will see. Husky..try the higher throttle setting and let me know how yours reacts. thanks.

2. Push hand throttle (A) forward from idle position (approximately 1/3 of full throttle).

OMRE260579: 5225 owners manual;; starting section

Owners manual makes great fireside reading. Sorry couldn't resist!!

 

[81husky]

C'mon, you only read the manual as a last resort. I jack the throttle up a little, but I can't say I've ever gone a third of the way when I start my tractor. It always starts just fine albiet with a little smoke. I'm 300 miles from my tractor right now, but I'll try a little more throttle next time.

 

[mfreund]

I went out tonight and fired mine up with a little more throttle and it seemed to help. I never saw it b-4.

My 5325 starts the same way-it has the 5 Cyl also. . Will also try a little more throttle.

 

[CAB/AIR5225]

Yep...it has surley helped with 1/3 throttle. It just seemed like a high cold start rpm to me. What do I know...I didn't build the thing!
