blowing smoke

[bubbu55]

My 08 ck35 is starting a little hard and blowing out more smoke than usual at start-up. It's just at start-up and then everything is fine, while I'm working with it I shut it off do do some work and it starts up fine with no smoke, just like normal. Symptoms must point to something and I'm sure I'm at the right place to get answers. Thanks guys.

Glow plugs not working as well as they use to. Or maybe one has gone bad.

My best guess is that the glow plugs are bad. Probably just one since it still starts somewhat normal.

You can test them with a simple multi-meter. There are loads of videos and guides out there on how to check the glow plugs.

What color is the smoke?

^^^ Important troubleshooting tip.

Yep, that was my first question as I clicked on the thread.

Check for power getting to the glow plugs

As Vince says, check the glow plugs. After that I'd be thinking injectors: not seating fully, dribbling fuel (residual pressure after shutting down and fuel pools up a bit); it's less an issue when starting warm because the excess fuel will ignite pretty fast.

SO many say the glow plugs but the glow plugs do not work when the engine is warm. If the OP only shuts the tractor down for a short period of time, the glow plugs will not work.

Yes and this is what the OP said.

Sorry guys, been out of town and just got back. The smoke is blue, I assume it's the glow plugs. How many are there on a 08 ck35 hst? If more than one, should I go ahead and change them out while I'm there? Thanks again.

I'd just ohm out what you have: tip to ground; 0.4-ish ohms? Not common to have them all crap out on you; usually just one goes bad. Another thing, and why checking them first is a good idea, is that the wire harness could have an issue: I have no idea what things are like on the ck35, or on my NX for that matter! (I do know for my B7800- it uses just a metal bar, which is kind of hard to go bad). My cars, VW TDIs, will see a bad glow plug from time to time and or a wire harness gets old and brittle (only ever changed one of these). Having a spare GP or two on hand isn't a bad idea.

My B7800 is a 2006 (or 2004?), with 1,850 hrs, and it still has the original GPs.

Well, you say that the colour of the smoke is blue? Usually that means engine oil in the smoke. Unburnt diesel fuel and the colour would be more white. Restricted air filter or a high load on the engine would cause black smoke. How long has it been since an oil/filter service? Are you using correct engine oil, ie a diesel oil with a CD or CF or higher rating? Is the oil level reading high? Dutchy
