Performing the Cummins Marine Idler Pulley Upgrade for the 6BTA 6B 5.9 330B Diamond Series
In this video I describe and perform the Cummins Marine idler pulley upgrade as recommend by Seaboard Marine.
The process is applicable to B series 6BT 6BTA 5.9 and C Series Cummins Marine engines.
Please note I am not a professional marine mechanic.

This video is produced solely to share my experience maintaining my own vessel. It is purely informational and opinions expressed are my own. This video is not intended to replace the advice of a certified marine mechanic. Modify you your vessel at your own risk.
These are to be air tested at 30psi via Cummins
Great Video! My upper hose split. Can I just change to and see if it is just a bad hose?
How often should the aftercooler be cleaned
Good stuff - purchased boat w/cummins QSB 5.9's this fall and will remove and clean, test, etc in the spring. little nervous but looks fairly straight forward. Thanks for the video!
Just finished both aftercoolers and tested per your setup. Works like a charm! TY!
Are you sure its 315 horsepower. My specs say 205 horsepower. Also, how are you going to pay off Pink Floyd when they sue you into the dirt ?
Dude! Props on your instructional video. You gave perfect info, great images of what we needed to see, and used a camera on a stand or tripod. Those are three things that most other UA-cam videos lack. Most hold their phone with one hand and attempt to work with the other. Most give lousy narration. Most leave out the parts we really need to see. Please do more as I’m currently in the market for a used Bayliner 3788 and want to do my own survey and my own maintenance. I’ve worked on gas engines most of my life and believe I’ll pickup the required diesel knowledge that I need pretty quickly. Oh, and how the hell are you getting away with a Pink Floyd song and not snubbed by UA-cam?
GREAT!!! Now let’s see it on the PORT ENGINE. Next to impossible to get at and had to remove a motor mount to access the water pump.
Followed your plan and tested my aftercooler, marine gear cooler and heat exchanger, great job, worked perfectly. Thanks for the video.
How was it that you extended the fuel supply and fuel return lines?? Barbs and clamps??
Not just the cross section area, its the grade 8 which makes it bulletproof.
Did I hear you correctly, did you change the fuel banjo if so what did you use?
Well done.
Just wondering why you don’t test to 30 psi ... given your turbo should be pushing 25 -30 ?
The boost can hit those numbers but remember that on the other side of the aftercooler o-ring is the seawater pumping though which is under some pressure as well (100% determined by how clear or how blocked your coolers are) so the o-ring is subjected only to the delta between the two pressures.
Nice vid. Tks.
Nice video. I have a new-to-me regal 4160 with Cummins 6bta 370. Looking forward to seeing your oil change video!
Sure. I'll put that on the schedule for the early spring.
Nice video, thanks for the shout out. I just did this in our shop yesterday on a 6BTA 370. Nice looking boat too. Enjoy it! We are here if you need anything.
Thanks and thanks for the forum and tips. Looking forward getting my Cummins rigged "Seaboard Style."
What on God's green earth could have been blocking your cooler that bad. I think it was just a bad hose stretching more than the other and you had a bunch of impeller pieces on the bottom side of the aftercooler. Regardless I understand not needing them on a 330 horsepower application as long as you keep enough fuel in the tanks. However I think you should add them to your video during your recommendation of blowing air through the return that they pull their fuel fill cap off the tank so that if using an air compressor they don't split the tank open. In addition to that I don't know why unless somebody put a draw tube on your return as well you would ever hear bubbling through your return unless your tanks were slapped full technically you want all of the return fuel to fall on top of the fuel in the tank quickly dispersing the air bubbles created by agitation of circulating fuel. Rather than injecting all of those bubbles into the bottom of your tank presumably right next to the draw tube.
Matt thanks for your comment. Please watch for a video detailing the cause of restriction.
@@diydieselrepairandmaintena7390 i look forward to it. I just know the suggestion it was the cooler is 99.9% inadequate. The only way to blow the fuel pressure side of the cooler up enough to restrict water would be fuel freezing wich doesnt happen until -30° Celsius. So highly unlikely. Or way to high of fuel pressure ballooning the thing. In any event their isnt enough metal to allow it to happen prior to tearing. Or at minimum blowing up the induction brazed where the fittings are installed... The new seawater pump makes me consider the aftercooler could be chalked full of impellar parts. Old zincs. Corrosion and god knows what else.
@@diydieselrepairandmaintena7390 What was the cause of the restriction? I didn't see or hear it mentioned in your video. Great job on this!
