Thank you for yet another great informative video! Your timing is serendipitous, I was just looking into doing this myself and what type of oil to use!!! ❤
After viewing the first video I saw, just based on your critical thinking, my guess was you were an engineer by education. You make these buses easy to understand. Much appreciate your time to make these videos!@@TedsGarage
Great overview. I used a similar thought process on my coach's rear diff. I replaced my fluid the first time at around 55k when we first bought the coach, then around 80k and now when it has >140k, also with synthetic 75W-90 GL-5 gear oil. I use the same gear oil in my tag and steer axle wet hubs as well. Also just replaced all of the air springs on mine a couple of years ago as I was starting to see some deterioration at the bulges. I have always gone through a similar process as you are with coaches and vehicles, zeroing them out before I commence using them, then regular preventive maintenance during ownership. I'm curious how many miles are on your Detroit Series 60 and if you are planning on running an overhead on it? I recently ran the overhead on my Cummins ISL @ just over 140k and Cummins recommend adjustments @ 150k miles. If memory serves the Detroit manual states first valve adjustment @ 60k miles but I've heard many don't do them until around 100k or so. Just curious as I'd like to see your video on running the overhead if you are planning on it. Thanks Mike
Mike, I definitely do plan on running the overhead on my Series 60. It’s got about 104k miles on it and to my knowledge it’s never been done. Based on the Series 60 groups I’m on it definitely should be done and I’ll probably see an improvement in performance and economy. It’s on the list, but after some more preventative maintenance and repairs. I’ll definitely make a video when I do it.
@@TedsGarage looking forward to it. Mine were all a few thou on the tight side @ 140k + miles. Not terrible and still within the specified range, but tighter than the setpoint and was worth doing it. The Jacobs compression brake was pretty much spot on though. Thanks for the quick response. Mike
Not sure if you saw my video on my 3126, but I did find several on the tight side. From what I’ve read the Series 60 does generally wear enough to warrant the adjustment. Mine doesn’t have Jakes, though - I have a transmission retarder, which I’ll do a video about at some point as well. I was a bit unhappy about it not having Jakes, but the easier overhead is nice and I find the transmission retarder to be a good device.
Thanks for the video! I have a 04 Monaco Signature with a series 60 (14L) and I'll be changing my diff fluid this spring while following your recommendation. I'll also be changing my tag axle hub fluid too. I already changed all my filters and my fluids over to synthetic, other than my diff and transmission. I also modified my exhaust system on my motorhome, installed a K&N air filter replacement. (38-2002S), and my EGR system. (theuglyfix) I was curious, what's your thoughts on tuner devices for our series 60? I am also always thinking of ways to improve efficiency, and one I have been thinking of was a tuner. I am not really going for crazy power gains (want to prevent excessive EGTs), instead MPG gains. You mentioned driving your coach in cold weather (10F or more) (possibility for salt conditions), have you looked into undercoating? I recommend fluid film or wool wax. I don't recommend anything that cures or dries hard. Also, take a look at a product called saltsgone, to rinse your coach off after driving in salty conditions.
From what I've found so far on the Series 60 most truckers with this engine get it tuned by a professional rather than buying a tuner. I did this on the 3126B on my previous RV, and that's the route I'm planning on going for this as well. You definitely want to make sure who you use is reputable. I'm mostly interested in fuel economy improvements like you, but I also have a few other things I want to do to improve drivability, a few things that will be out of the box. Look for a future video on that - I'm not sure when exactly I'll do it, but most likely sometime later this year. Also, I'm assuming you have either an Allison 4000 or B500 - I'm working on an upcoming video on changing the fluid on it. I did the change already a month or so ago, I just have to finish the editing on the video. Look for that coming up soon! Good tip on the K&N filter! I'll have to check the measurements and see if that would work for my Prevost.
@@TedsGarageThank you! I’ll keep an eye out for videos. Check out PDI performance (big boss tuner), they tune very well and have tuners and additional parts available for our series 60. If I remember correctly Newell uses PDI as well for tuning customers coaches if requested in the build.
@@TedsGaragealso this could be a monaco thing, but if you have a plastic coolant level sensor, replace it ASAP with a metal sensor. If you have coolant in the terminal housing its already bad. It leaks down the wire harness making its way to the ECU eventually destroying it. part: 23520380
@@Austin2276 I'm familiar with PDI, I'll look at the tuner for the Series 60. Just a quick glance makes it look a lot more expensive than a custom tune. I've also got a few out of the box ideas I want to do (aimed at improving drivability in the mountains among other things). But, I'll investigate more. I considered their manifold and turbo on my 3126B, I'm looking at maybe putting a Full Tilt manifold on the Series 60.
Yes. Enjoy watching and never to old to learn new stuff. 😂 Keep them coming
Great to see all these videos on the Prevost.
Glad you like them!
The engineer in me really enjoyed this video! Those differentials sure make my Dana 44 diff look tiny :D
You clearly should put a Meritor axle in your Ranger! 😁
I enjoy your over-thinking LOL, always feel like i learned something new
That’s the goal!
Thank you for yet another great informative video! Your timing is serendipitous, I was just looking into doing this myself and what type of oil to use!!! ❤
Glad this is both helpful and timely!
Thanks again great video.
Thanks for the video.
Thanks for watching!
excellent informative video, thank you! what type of engineer are you? much appreciate your videos

@@TedsGarage yes, you will like the retarder. Just have to pay a little closer attention to transmission temps but generally not an issue.
