Volvo TAMD 74P obsolescence, maintainability
This topic has 1 reply, has 2 voices, and was last updated by
5 months ago November 21, 2023 at 6:35 am Iām looking to downsize from my 58ā Viking with 1200 hp manās. Looking at a 42 post with 480hp TAMDs and wondering how bad the Volvos will be to maintain.Ā <br /><br /> I previously had a 38 Bert with Cummins 480ceās and loved how easy it was to get parts and advice here on this forum. Stepped up to the 58ā viking which is an awesome boat but Iāve needed to hire out a lot of the work and itās really just too much boat for us right now…

1 ReplyNovember 22, 2023 at 8:10 pm If long term parts availability and reasonable service cost are part of what you are seeking, look for a vessel with Cummins engines built from the early 90’s on.. The 5.9 B or 8.3L C’s are the engines of choice… In the best of times, getting anything for a Volvo marine engine has always been a challenge,Ā at least here in S. Calif.Last Post by:

Engine Data on 480CE J1939 bus?

November 15, 2017 at 10:06 am This came up briefly in another discussion but I thought it made sense to make the topic it’s own thread. Does anyone know if, on the 480CE, the engine data (such fuel burn, loading, RPM, etc) is sent over J1939 bus as well as the J1708 bus? The “C8.3 Marine Electronic Control System Troubleshooting and Repair Manual” shows a pin-out for the 9-pin diagnostic connector that shows both J1708 and J1939 high and low conductors. B…

1 year ago September 30, 2022 at 8:25 am I’ve got ZFBW165 mated to 1200 hp man’s.Ā The port oil cooler has been leaking.

6cta oil leak – options?
This topic has 10 replies, has 6 voices, and was last updated by
3 years ago October 13, 2020 at 4:01 am My port engine has slowly leaked oil as long as I’ve had it. Generally had to add a quart a couple of times a season (every 50 hours or so). Just did ~400 nm in 3 days and it suddenly has gotten dramatically worse – now need to add a quart every ~8 hours and the leak is pretty visible. I may have more than one leak…but this seems to be the main/worst one. How sensitive are the oil pan bolts to over tightening? Can I grab a la…

Old onan Genset Alternator failure – what are my options?
This topic has 3 replies, has 2 voices, and was last updated by
3 years ago September 26, 2020 at 8:11 am The alternator on my 1989 vintage 8kw Onan genset failed, and broke the alternator bracket. Or possibly vice versa. When I turn the alternator, it doesnāt turn smoothly – itās ālumpyā feeling, which I assume means bad bearings.

3 years ago September 11, 2020 at 10:59 am I had new aftercoolers installed about 2.5 years ago, so its time for them to come off for their first service. They were ordered from here, so they should have been greased up properly, etc., and not to bad to service (fingers crossed), so I’m planning on doing as much as possible myself.

September 20, 2020 at 4:57 am I only saw the spray cans – so I just alternated between spraying them down, rinsing them off, drying them out, and repeating. It was very time consuming. Soaking may have been a better bet. The guy who runs one of the diesel shops here at my marina told me next time to just drop the cores off and heād put them in his cleaning tank for me. Iāll probably take him up on that next time. I donāt feel like I got them as clean as I wanted to.

How Do Diesel ECM's Typically Calculate Fuel Burn and Engine Load
This topic has 9 replies, has 6 voices, and was last updated by
3 years ago
October 16, 2018 at 9:52 am Wondering if anyone knows, for marine diesel engines with ECMs, what the typical approach is for calculating fuel burn and engine load as reported by the ECM? I had assumed the fuel flow was monitored directly and that was reported by the ECM, and compared to the RPM and perhaps other factors to calculate engine load. Over the weekend, a cummins tech told me that typical “recreational” class marine diesels do NOT measure fuel consump…

4 years ago March 28, 2020 at 5:23 pm I’m not getting any raw water flow through my late 80s vintage 8.5kw genset and am out of troubleshooting ideas. Hoping for some suggestions.

It ran for about 10 minutes then the fault breaker tripped. Once I figured out what was going on, I …

confused about oil for 480ce 6CTA
This topic has 4 replies, has 3 voices, and was last updated by
5 years ago November 4, 2018 at 2:13 pm I’m getting ready to do my first oil change and I’m confused about the engine oil specs. The manual calls for ces20071 or ces20076 oil, or CG-4 or CH-4.
