Volvo 270 tilt motor relays

[am_dew]

To make a long story short, I am unable to lower my 270 tilt-only (no trim) outdrive (all I hear is a single click each time I toggle the tilt rocker switch on the dash panel to "down") and I have good reason to believe that the "down" relay is bad.

But I cannot tell in looking at an online parts diagram, exactly which relay is the "down" relay and the old relay has no markings on it. I am pretty sure I have physically identified the down relay by listening for the "click" as being the relay facing the bow and mounted to a bracket on the tilt assembly near the transom.

Does anyone know for sure the OEM part number or after market replacement for the "down" relay for a 270 outdrive?

Thanks!

P.S. In case anyone is wondering, the tilt motor works fine in the "up" direction, so the motor is apparently fine.

[colour=blue]If you can enlist the help of a friend, have them touch the relays as you toggle the buttons. He/she will 'feel' which one is clicking.

Thanks. Through the help of a friend, I have identified the relay I want to replace, however it does not have any markings or anything else which would allow one to cross reference or ID it. I was hoping that maybe someone might know the OEM or after market part number for the DOWN relay specifically.

ive got the whole outdrive with tilt gear for 500 and its all one layer of paint. good shape.

Re: Volvo 270 tilt motor relays

It takes both relays to operate either up or down. All the relays are doing is switching hot and grounds to reverse direction.
You need two relays. See picture for Volvo part numbers and location.

Re: Volvo 270 tilt motor relays

Thanks Don. My relays are not housed in a box like in the pic you posted and instead are mounted to a bracket which is attached to the top of the lift assembly. In any case, I am trying to determine which of the relays in this picture is the one that I suspect is bad...#23 or #24? Again, I have physically identified the bad relay but it has no markings on it to give me a clue as to which relay in this pic it is and I don't really see any other clues in the pic that would help me cross reference the actual part to one in this pic.

Re: Volvo 270 tilt motor relays

In your picture, relay #23 is Volvo PN 241812, #24 is PN 876040

Re: Volvo 270 tilt motor relays

Don, with all due respect, what is your source for these part numbers? The reason I ask is because I came up with #23 Volvo PN 870670 and #24 Volvo PN 1214764 as found on Shortsmarine.com, which is where the picture I posted is from. I know there are often cross references so yours and mine could very well be the same parts. Just wanting to be sure here.

I "mirrored" the picture I posted and found that by looking at it that way, it better matches what I actually see on the boat. If I am correct, #24 is the relay which just clicks. But I'm going to do a little more troubleshooting before I do anything else.

Re: Volvo 270 tilt motor relays

Excellent....thanks again. It took me a while but I was able to cross reference the part numbers you provided as being the same parts I found, by matching them with after market parts. For example, the Arco Marine relay R040 replaces Volvo 876040 and 1214764, as does the Sierra 18-6266 and the MES RL-004. Don't you just love it how Volvo uses different part numbers for essentially the same part when it's just used in different model units? Or are these after market companies just creating "generic" parts that cross reference back to multiple Volvo numbers without paying attention to exact details?

Re: Volvo 270 tilt motor relays

For one thing, I haven't seen one of those style tilt mechanism and relays in about 10 years, but I would bet the aftermarket relays lack all the brackets necessary to mount the relays in the relay box. Volvo has them made onto the relay.

Re: Volvo 270 tilt motor relays

Yep, it looks like you are correct, at least for the Sierra replacement. But as long as it can be mounted in such a way that the wires reach, I would not think it would matter. But you're right, it's always best to use OEM parts if at all possible.

Re: Volvo 270 tilt motor relays

I did some troubleshooting yesterday and found that I had 12V feeding the tilt motor when toggling the tilt switch in both up and down directions. The motor has always worked fine in the up direction so I applied 12V directly to the tilt motor on both "up" and "down" positive terminals and sure enough, it only operated in one direction (up). So, I started calling around looking for a new motor and found a used one at a nearby marine recycling center for about 1/2 the cost of a new one. So I buy it , come home and test it before I installed it and it worked fine in both directions. So, I install it and flip the tilt toggle switch and all I get is clicks in both directions of the tilt switch. The motor worked fine when not installed so I knew something was wrong somewhere in the installation. Before I installed the motor I noticed that if the nuts (#21 in pic above) on the motor face that hold the threaded mounting shafts in place are too tight, then the motor shaft cannot be turned using your fingers, so I made sure that these nuts were tightened up just so that they made contact with the motor body and there was no play in the motor mounting shafts. So, knowing that if the motor's face was too tight against the motor body that the motor shaft would not turn, I thought that perhaps I had tightened the two nuts (#43 in pic above) used to attach the motor to the tilt assembly were too tight, so I loosened them a bit. A test then revealed that the tilt motor did in fact work in both directions and was able to lower and raise the outdrive.

Even though the motor does raise the drive, it sounds like it's strainingg pretty hard to do so, so I am a bit concerned that perhaps that I still have the mounting nuts a little too tight and the motor shaft is straining to turn in the up direction (it sounds fine in the down direction). Does anyone have any good advice on how tightly the motor should be mounted so as to not cause the motor to not work (or be strained) but still tight enough so that the splines on the motor shaft are able to make contact with and rotate their intended targets? A few years ago I had to remove and reinstall the old tilt motor and I don't remember ever having a problem like this where the tilt motor did not turn because the motor was mounted to snugly...I just snugly tighted the #43 nuts and all was fine.
