LS XR4140H Regen intervals

[RayfromTX]

I recently bought a 4140h. When I got it home it had 5 hours on the clock. At 25 hours it went into regen which was disappointing but I figured it made sense because on the lot it was started twice a day to move it in and out of the warehouse. It sat on the lot for a couple months so I decided I would just see if it was longer until the next regen.

I start it and warm it for about 5 minutes at 1500 rpm. I operate it in the 2k to 2,400 rpm range. I cool it down in the 1200 rpm range for a few minutes as I put it away. I have been working it hard for several hours at a time. 18 hours later at 43.5 hours it went into it's second regen. For a machine that is estimated and reported here to go about 50 hours between regen cycles this seems off, especially considering how I am using it.

Does anybody have any ideas why this may be occurring or similar experiences? Should I bring this to the dealer's attention? They may say it's not hours that causes it but 70 percent on the canister, which is true buuuuuut, why am I not getting close to the estimate? Is this an indication of something that shouldn't be ignored?

My XR3135 is acting identically. I just haven't had time to work it any yet this year. I am nearing the 50 hour mark and have had 2 Regens. All my hours have been in Fall and Winter. I also hope the Regen interval increases.

I just received my XU6168 yesterday and when the dealer was going over the tractor with me, he said it may regen 2-3 times before the 50hr serv. His explanation was that its better for the tractor to regen 2-3 times in a 50hr period because there's less soot to burn off between regens. A single regen every 50hrs the regen has more soot to burn off and may not get it all thus still continuing to build up over time causing problems for your tractor down the road.

Interesting spin. I guess they are finding a way to explain why it isn't matching the marketing materials. I did the 50 hour service this morning at 45 hours. Exhaust manifold bolts weren't checked yet because I haven't figured out how to do it without removing the turbocharger. I also still need to check the frame mount bolts for proper torque. So far everything I have checked has been way too tight. The oil drain plugs were probably at 100 ftlbs or more. The filters were way too tight. The wheel bolts were far tighter than spec but I haven't loosened them to spec yet. I will before too long. Some of the zerks on the backhoe were unusable at the angle they were tightened to. I loosened them, added grease and retightened but they need to be replaced with something that can stay in place while being greased. Some of the zerks took lots of grease the first time when I got the machine. Beware of greasing the main axle bearings. I blew out a bit of one of the orings. I'm mostly good to go for another 250 hours now except for the perpetual grease game. So far so good. The hydro filters had a good bit of particulate in the fluid that drained out of them. I'm glad I changed them just to ensure the max flow through them. The engine oil was not troubling visually. I won't bother with an analysis.

my xr 4155 had its first regen at 50 hours

You might ask your dealer to reflash the ecm to the most current software.
I’ve got a 68hp engine, but it always regenerates at 50 hours, plus or minus one hour.
I wonder if your engine isn’t broken in yet and it’s burning oil and making soot. Has the oil level changed at all? Does it have a diesel fuel smell to it when you smell the dipstick?
On older diesels, the exhaust can you a lot about what is going on with the engine. These new DPFs catch all of that, so you don’t know if it is running rich caused by a leaking injector, or burning oil from a bad valve seal or worn rings, or maybe has a bad head gasket allowing water into the cylinder. We are stuck relying on the computer to tell us when something is wrong.
I suggest using Rotella T-6 at your 50 hour service and see if that helps at all.

I used Rotella T-6 this morning. I did my 50 hour service at 45 hours because it was a cloudy morning and in Texas in July you take those when you can get them. Oil was clean with no off smell. If it isn't broken in now, it isn't going to break in fast with the synthetic oil. That stuff is the bees knees.

I just had my second reign on my XR4140 cab tractor right at 89 hours.

 

[lostcreekranch]

My XR4155HC did it’s first regen at exactly 50.0 hours. Haven’t had second one yet, I’m just passing 58 hours.

 

[Drewmon]

Mine was at 49.3 hours. XR4140HC

 

[Maxify55]

It's been 5 yrs on mine and I barely notice that it's even occurring.

You'll be the same way.

Enjoy!! They're great tractors!!

My third region happened at 29 hours after the second. The Tractor is now at 76 hours after 8 weeks. Loving the tractor so far.

I had a weird thing happen around 21/22hrs. Started getting a weird burning smell, maybe like burning paint but not quite. I noticed one of the regen lights (the one with the thermometer) was on and believed I had just experienced a regen. I'm still not sure if I did or not. After the light went away, so did the bad smell. I came here to the forum and discussed it a bit; found out that a regen involves two lights on at the same time. Yesterday around 30hrs I noticed another burning smell not quite like the first. I was waiting for it to do regen but it didn't, just kept stinking. So I did a forced regen. I did it out of curiosity. Not sure if that's bad for it or not. But the smell is gone now.

According to my manual page 3-55 (XR4100) you should only have the dog regeneration indicator on in most conditions-if you have more than one on or the dpf regen is blinking the tractor is telling you something about your DOC and DPF

 

[lostcreekranch]

The first light comes on to indicate the DPF is being heated up. When the second light comes on the regen. cycle has started. When the cycle is over, both lights go out.

Not according to the XR4100 series op manual pages 3-55 through 3-57. According to the manual the only time two indications (one of which is the regen active indication) are on is when you have a soot rate over 150%-in which case the engine error warning indicator will also light and power will be reduced.

That being said it wouldn’t surprise me if the manual was not correct

I’ve only had a single regen. cycle on my XR4155HC at 50.0 hours and didn’t really pay much attention.

The description, in my previous post, was how the regen. worked on my XR4046HC and I “assumed” was same on the XR4155HC.

My apologies. I suspect the manual is correct.

How old is your LS and What is the P/N and date code on the back cover of your manual?
I have:
2017 XR4140, purchased new 06/2018
manual P/N : 52116804-03
manual Date: 20150000

My manual makes ZERO reference to the DPF temp lamp. Only the regen and regen inhibit lamp. And for a 150% soot condition it says the DPF lamp will flash fast.

The original manual for my tractor was lost by the dealer before I purchased the tractor; this one I have was ordered by the dealer two months ago, directly from LS, and then forwarded to me. To me, this means it should be the most recent REV of the manual. But the date on it is 2015. I knew it must be dated information (not showing all the lamps, plus other issues) but I assumed it just hadn't been updated by LS since 2015. Now the things you're quoting from your manual don't match what's in my manual, and I wonder if you've got a more recent copy than I do.

The only indication I have to the function of the DPF temp lamp is the sticker on the fender, which ironically suggests the opposite of the sequence quoted below:

Re: LS XR4140H Regen intervals

The first light comes on to indicate the DPF is being heated up. When the second light comes on the regen. cycle has started. When the cycle is over, both lights go out.

According to the sticker, Regen lamp comes on when it needs to regen, temp lamp comes on later when it's up to temp to perform its intended regen, and then it regens.

I can't confirm the sequence suggested in my manual, or the one in GSVette's manual, or the one on the sticker, OR Gustafson's observations. So far (only 30hrs) my only experience with auto regen was when the DPF temp lamp alone came on and I'm still not sure if regen occurred.

It would be nice if the documentation provided by LS was clear, consistent, and accurate.



EDIT: Personal observation... when I forced regen, both lamps were on for the duration. Not sure if this has any relevance to the auto regen sequence.

I think I was composing my reply while you posted yours, so I didn't see it until now.

Whose manual are you confirming? My manual doesn't match his (or the sticker)
