I am looking for information on my engine/reverse gear configuration (D3-150i-G/HS45AE-C). I know that Volvo Penta did not provide my engine equiped with a reverse gear to RT. They apparently were sold seperately to the RT factory or some other enity that assembles the engine/transmission for RT. I have asked both VP and RT for the information needed but have not received a response to date.

What I need is information on the interface between my engine and reverse gear. This interface is either called a damper plate or torsion interface. Looking at the breakout of parts from VP this interface is madeup of 3 elements (see figure): item #3 the Adapter Ring, item #4 the Flexible Coupling and item #45 Plate. My configuration did not have item #45 Plate installed on my engine. I don't know if this was by design or possibly left off by mistake.

If anyone out there has information that would help me determine if that plate is necessary for my configuration I would really appreciate your help



Thanks, Dick
 
Hello,

Please send Tim Bates an email directly. It’s timbates@rangertugs.com. I know he has read the post but wasn’t sure himself. He has been in contact with VP but, that will be the best place to talk about this issue.

Thank you,
 
I am becoming extremely furstrated in finding out engine/transmission configuration for my RT25SC, which should be easy. It seems it is a national top secret. If there are any Volvo Penta dealers or certified mechanics out there that can help, please send me a private message or email at rtclagett@gmail.com. I am willing to pay for your research to get the information I need. I have already done significant study and have narrowed it down to one statement in the installation instructions for the damper plate for my configuration. Seems like no one can get info out of Volvo Penta.

Thanks... Dick
 
Dick, I feel your pain! Getting information from Volvo is almost impossible. When I called for technical service information all they would do is give me dealers names and telephone numbers. I would explain to them I have talked to theses dealers and they do not know the answers to my questions. When the dealers call for information they told me that the phone service technicians at Volvo would ask what parts do you need or read the manual for the information. We will authorize and send tany parts you think you need. I had one dealer tell me you know more about the D3 than my technicians do. We don't work on them! Yet Volvo would send me to this dealer.

In your case look at the serial number group that your engine falls under. You can not always go by the year of the boat to the year of the engine. When a boat manufacture orders engines many times it is in bulk. So a 2013 engine can be in a 2014 boat. There are several serial number groups for the D3. There have been engine coupling changes thru out the years. Match up each component and part# that was removed from your engine, Flywheel, adapter ring, coupling and spacer plate (45). My guess is if your engine serial number group requires the spacer plate to be used and it was not there. Someone forgot to install it. If it is part of the parts drawing assembly I would install it. When I was a service technician I would find items of discrepancy while repairing an engine, transmission, stern drive or lower unit. A quick look at service bulletins, manual and a call to a subject matter expert at the manufacture would be done. A conclusion based on the information found would determine the assembly.In your case if no person or literature would define the assembly and I was the servicing technician on your boat I would install the plate to the assembly. If everything matches up and there is a good fit. Based on the drawings and manual this is the way Volvo designed it. At that point I would speculate that someone may have forgot to install it. Good Luck, it should not be this hard to get information on that new of a product.
 
Brian,

I have provided the serial number for both the engine & reverse gear to those I have requested information on the applicability of plate #45 for my configuration. By the way the plate is actually an added weight not a spacer. That is why I think it may be needed for my configuration. I don't know the time frame but there were many ZF-Hurth reverse gear failures a few years ago, mostly on Cummings diesels using an insufficient damper plate. This may be the fix for Volvo Penta using the ZF45A series reverse gears. This plate would provide additional mass to absorb engine vibration.

I did find the installation instructions for the damper plate. It states in the instructions that this plate is an option. It does not define what the option is for. However these instructions are for my engine/transmission configuration.

My engine/reverse gear is a standard configuration for Volvo Penta D3/reverse gear series. One would think that VP would know what parts makup that configuration and any service bulletins since it was manufactured.

Thanks again for you help.

My local Volvo Penta dealer, 110 miles away, finally received a message from Volvo Penta in Sweden which said: "The Plate is only needed in certian situations. If the engine does not have one now, then don't put one in."

OK. I think I have an answer although somewhat obscure. Being an engineer I would like to understand what "situations" means. However, it looks like that's all I am going to get.

I feel very uncomfortable not knowing what caused my failure at the begining of September and knowing that another 2014 RT25SC, same configuration, had a similar failure this August on the great loop.

I would like to thank everyone that commented on my post, your posts were greatly appreciated.

In my own quest this week for information I found BB Marine to be 100% correct. It has me shy away from Volvo Penta and starting some research into alternatives for my upcoming purchase. I ended up on the Cummins website. A gold mine of information. What a different approach. I know, not an option for us. Just pointing out the utterly different attitude towards information sharing.
 
The more I read up on the parts and servicing associated with the Volvo Penta engines, the more satisfied I am with our Yanmar 4BY2 engine. Oh, the Yanmar is not without its issues but overall I’m glad I have it!
 
Just for clarification I have not had any trouble with the Volvo Penta engine. Every time I have hit the start button it starts and runs perfectly. The physical problem I have is with the ZF-Hurth transmission attached to my D3. Getting information on VP products and there iterface to third party products was my problem. Working through a VP dealer is the only way to get information and sometimes they have problems. Also don't expect a timely response or any background info that may help you understand the response you get.

If you have a VP product find a good dealer, give them some business, so when you need help they know who you are.
