Good morning! Yes, Mouser and digi-key would be the first places to start the search. I will do some research when I get back tonight to see if I can get some better information for you.

Hi Bob, I believe you are talking about the air dryer. Haldex makes them and have a few different models, I know this is asking a lot but- if you have a picture, I can give you the part #. As a man of my word, I owe you a donut... 99 out of 100 times of not building air or 'rapid' air leak will be your governor. Your governor was nearing the end of its service life so consider that "preventative maintenance" and potentially a breakdown on the road, and of course it would happen to be at not so convenient time nor place. 🙂

Howdy, I would it it will a squirt of PB blaster then give it a few mins. Should do the trick. 🙂 One other thing you can do- hit it with a little heat (not much) if you can.

Hi Bob, I sent you a message regarding your issue. Did you get it? If you need anything, msg me and I am glad to help. 🙂

Hi Bob, I would bet a dollar to a donut your air governor gave up the ghost. The unloader fails so you either slowly get to 120 psi or you get nothing. You are at the later... They are cheap and relatively easy to replace, if you still need help- send a msg on here and I can guide you if you would like to replace it yourself. You could be back on road in 1 hr tops once you get it to replace. Two other things I would do prior- disconnect the discharge line from the compressor to check and make sure you are getting pressure. If you put your thumb on the end and can't hold it there because of the pressure- your compressor is good. I would also check the lines to the dryer, to make sure you don't have any leaks. When did you replace your dryer cartridge? I always recommend Sep/Oct of every year, depending on how much use you get. Best of luck sir!

Merry Christmas Monacoers family! Another year is almost in the books, and hopefully, a better one ahead! I just wanted to wish everyone the best and say thank you too all and a big thank you to the moderators for keeping this going!

Hello Steve, I have installed 3 of the Webasto diesel fired heaters, and so far they have been awesome performers. The airtop 2000 ST (they also make them for gas units) are a quick install and require little maintenance. They only issue we ever hear about is after the diesel sits in the fire chamber over the summer and the unit tries to fire 3 times, it will go into "timeout" mode, I believe its called. But that is an easy fix. If you are looking to put it into a large coach, I would recommend going with a 5.5kw or larger, then duct it if you wish, but you won't be happy with ducting a 2000. It has a 3-4" fan which does a heck of a job for a 20' coach, it will roast you out once up to temp and is very quiet. But for a 40'+, not so much. Use the included 4' flexible high temp hose, cut it down to length, duct it to your desired location and enjoy. I would recommend getting and having on hand their tiny, over priced replacement fuel filters because they do clog up, and fast if you get bad fuel. Overall, it is a straight forward install. You may have to tap into your fuel tank if you don't have a spare port to tap off of, It does come with a 24-30" fuel pickup (if memory serves correctly) to make your own pickup, if you so desire. You will have to insert it from the top, we had to drop the fuel tank which was not fun but doable... It draws so little fuel, I was surprised when we did a test with a 1 gal container. It lasted over 14 hrs with temps in the 20's. Yes, their coach was insulated well but still, that is amazing. If you are looking at supplemental heating once the coach is up to temp and it is not below freezing, in my opinion- you should be able to maintain current temp pretty well with very few caveats. If you go with the larger 5.5-6.5kw, you will have no issues. Best of luck, and please let us know what you decide. 🙂

Hey Dean, disregard the ‘7th injector’, we work on Detroit’s as well and they have the 7th injector, that is to spray diesel/ DEF fluid (urea anmonia) into the DPF. Just going off of memory for that repair. I’m getting ready to speak with my diesel tech this morning and will get back with you, I’m hoping we have some value to add to the conversation. 🙂

Mr. Tom, what a surprise. I kind of figured you were bird doggin'. 🙂 I haven't heard from you in forever, and thank you for chiming in. I sure hope I don't have to eat crow on this one, lol. It has been a few yrs since that unit I referenced came in, but that was one of the trickiest ones I had seen. He does have a slew of other issues, but the one that I hate the most is anything to do with DPF systems. Detroit, Cat, Cummins, Mercedes are all different and have their little intricacies. We can only hope he gets it to a good shop.

I agree with you 100%, but this is "post covid times" where techs decide if they want to come in to work, what they will work on, if the DC has parts etc. These are NOT normal times. He replaced the VGT which tells us a few things, but has a lot going on to say the least. Thanks for understanding that he was asking for help, and I put my $.02 in. 🙂 I only have 17 yrs in the diesel repair industry, but my 65 year old diesel tech has been doing this since I was in diapers. I sit back, watch, and learn. Btw Frank, you are a plethora of knowledge, I found you guys back when I bought my coach and had some Monaco specific issues. This group is one of a kind! I miss Tom Cherry, you and a few others posting what seemed to be, daily. I would wake up and see 10 hits on my phone from this site. I truly enjoy the camaraderie on here. 🙂 Well Dean, I hope this at least has given you an Idea of where to go from here. Best of luck, and we will be anxiously waiting for your reply!

Hi Frank, I am relatively new to the group and don't know your background other than you are a legend around these parts, you are always spot on, always have great advice 🙂, and I have the utmost respect for you. I am not disagreeing with your hypothesis, I just didn't explain the whole process in the reply to keep it short. I am guessing they have done that last go around, but I am willing to eat crow on this one... We had one come in with the almost identical issue, HEST light on every time it tried to regen, stage 5, etc. I don't think he would be best served by going back to the same shop, IMHO. Whenever we throw the laptop on, we always do that amongst other things but the forced regeneration is usually the tell tale indicator. That one we had in would show that is was doing a 'passive' regen 5-6 times a day to the point it would start to derate. He brought in in and when we started a 'forced' regen- no dice, it puked. The unit really wasn't regenerating 5-6 times a day, the dummy lights would all come on in the cluster for the customer. So, that's why I say get it into a new shop, let them throw it on the laptop and start the diag process, with a new set of eyes. 🙂 Again, not disagreeing and but willing to bet a dollar to a donut the last shop didn't do their due diligence.

Hi Dean, If I were a betting man, I would say you have one of the possible following issues that I would address with a new shop: 1. Have them drop the DPF, if you haven't had it done in a year or two (never hurts since we have these crazy devices downstream now...) and have them clean/bake it. If you are dumping fuel/DEF ( I believe yours is diesel, but I could be wrong) in the DPF and it isn't burning, you could really be clogged up. 2. Check the sensors- I know, you have already done that. Here is why I say that: Once you bring it to a different shop- they can throw it on the laptop and do a 'forced Regen' and at that point the software does a "self check" and if you have issues, the software and tech "should" catch some of the faults that the previous shop had not and can correct it at that point. 3. It could be a bad "7th" injector (for the DPF), a harness that has gone bad, or a number of things I haven't mentioned. Also, I don't know your area otherwise I could suggest a reputable shop in the midwest but I would say find a class 8 (semi repair shop) that works on Cat, Cummins, Detroit, etc. Make some calls to find out if they have a scan tool/laptop that will work for you. I would call around 2-3 truck repair shops to get Diag quotes and find out what their 2 hr minimum is, etc. It won't be cheap but I can tell you I would probably find a new set of eyes to look at your ongoing problem. Best of luck and plz let us know the outcome!

They are a pretty amazing product in my opinion. Isn’t it nice to reuse a product over and over and know it will continue to do its job? Great quality, Made in the USA. That’s one product I recommend and know it won’t come back to bite me. Have you noticed longer wear life of the tire compared prior to using them? Nick

Hi Bob, I would totally agree that was Murphy at work! 🙂 The OEM relays were really good and 20 yrs ago Tyco was one of the best. We used them all the time with ZERO failures. I bought out the last case from my distributor and have a few hundred left. They have since been gobbled up then subsequently rebranded a few times over. One thing I would caution anyone on would be using the ones off of Amazon that you can’t pronounce. I had to get a few in a hurry away from home with none locally available and decided to get what would be delivered next day- the weight on the ‘el cheapo’s’ were half that of the regular 30/40 amp relays we always had used . I didn’t even use them because in my opinion, I would be expecting failure. With my curiosity getting the better of me, I opened one up ‘just to see’ the quality (or lack there of) and boy was I surprised!The wiper, contacts, and the it was constructed was pretty poor. The rating supposedly was 30/40 amps but I would guess 10 amps were more realistic. 😞 Nick

I don't have any experience with Balance Master, but I can tell you that the Centramatics actively balance and I can also vouch for guys running they on all axles on semi's as well. 1M + miles with no issues, and they seem to get more mileage out of the steers as well as drive axles. Just my $.02 worth. 🙂 In this category-whatever you choose is better than doing nothing at all. Thanks, Nick
