V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

[longstand]

I have been searching for this topic but they have answer for there problem..

but my is a little bit different..

I been trying to lower my outdrive and raise up
all it does it click click .

so i have remove the motor from the Socket and test it.. the motor Spin, it seems to be working very good..

but when i put it back into the housing. it does the same thing.. iam no expert but if the motor is not good it will not spin in any direction at all.

but when i try to lower the outdrive or raise it i could keep clicking . and few minutes and a few hundred click later it will be down..

i have remove the Tilt Machinism and clean all the old oil and replace with new OIL...

Also i have a twin engine. so the other Trim is doing the same thing.. its weird.. how can both Trim have the exact problem.. it was just working .. well it was barelly working. and when i did some maitainace on the engine it did this??

Ayuh,... Not to many OMC stringer Techs around...
Actually,... Not alota DIYers doin' old Stringers either...

I know Nothing about 'em,..
But,...
I'd say the motor is Beat, or it's load is locked up....

You might try marineenginesdotcom in the OMC forum,...
Chief Allen hangs out there,... Maybe He can Help,... Tell 'em I sent ya...

title says trim, but text talking about tilt.

Need to clarify which system you are working on if you want accurate search results and replies.

Spinning an electric motor with no load on it is NOT a valid test. A motor that is completely beat to death will still spin 1000's of rpm with no load.

While it's out, take it to an electric motor place (vacuum repair guys are familiar) and get it cleaned up, or google about electric motors and you'll learn how simple brush replacement and filing commutator bars clean is.

Grease the trunnion bearings on your outdrive.

Sorry Howard for the misunderstanding.. i am thinking that tilt is same as the trim...

well i have rebuilt a few of this motor before. i will just open it up and clean it up and i will see how is the brush ...l.

it was just weird that both of them was kinda working before i started missing around with the engine. and after a few weeks it dint want to work...

.. While i your here howard .. i know this is not in this topic but..

just to clarify this about this distributor. for my boat.. i have put the engine on TDC where #1 is up.. i remember you saying that i should put the dist properly or i will have problem.. WELL iam going to put it back tomorrow.

From my understanding and what i have read on the manual. the Rooter should be pointing and touching toward the #1 Spark PLUG wire on the Distributor cap? and then set the Timing with the timing GUN..

Ayuh,... That's Correct...

As the dist. drops in, the rotor will turn,... Start it ahead of where you want it to end up.....

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

Holy Molly..

I have Remove the Motor for the Trim/Tilt

IT was so greasy and dirty the contact was black. everything was black and greasy.. i clean it up perfectly and air dry everything.. well

From what i remember. Should there be some kind of magnetic field or something where it should been a little difficult to put the Armature back into the Field Coil??

I put the armature back Field Coil. but did not fell any resistance at all. NOTHING. it just set there.. i try the motor and it Spin really good. but when i put everything back. the Out-drive still will not move. Just click click.. I know its not the Solenoid.

. i think the motor is bad.. because i remember when i put the armature back on any kind of this motor there should be some kind of resistant . but NOTHING


Also. can it be TIlt CLutch problem or any CLutch plate.. ?? its really weird...
i have remove the Tilt CLutch cover and clean it up with Brake part cleaner and remove all that crap out. then i let it stay dry overnight so the sealer will dry up before i put some oil.. the next morning i put oil. and i tested it it will not work any more.... i have two of them tilt cluch cuz i have two engine.. its just weird that both of them dont work any more. all it does is click....

also i have just order 1 Titl Clutch from ebay.. iam going to see if that make any different before i buy another one... just incase if this motor is not the problem..

do you guys think if i let the tilt clutch stay dry it will not work any more or create some kind of a problem. remember the tilt clutch plate is very close together maybe it got stock>>> i let the oil set there for about 2 days now . and still the same problem..

Also the hammer-blow coupling. i made sure it had some play. so the motor could get a change to spin a little before it crab all that heavy load of my outdrive...

Also i follow this instruction..
http://mail.google.com/mail/#inbox/124473b6ac020b21
But did not put greese . u just added oil and let it set for few hours or days
weirdddd

. . . Idea idea... THis boat is costing more money than i expected

.. just making sure again.hehe

you said to make sure to start it ahead of #1 spark plug..

i assume when i set the distribute back into the engine it will move back touching the #1 Spark plug??. I'm correct

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

The distributor install is more complex than that. I suggest you follow my previous advice on this subject and use the Mercruiser MR185 manual.

I recommend two 0308799 gaskets under the tilt clutch cover instead of the factory one gasket, greasing the tilt trunnions, and filing both sides of all terminals on the high current side of the tilt circuit shiny. also file the nut shiny.

I also recommend you read up on the trim system and the tilt system before you go out in this boat.

Your referencing the trim motor as tilt/trim is going to cost you many thousands of dollars.

In other words, don't drive the boat with the drive in anything but the down position.

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

thats weird..

dont understand LOL..

There is a hydraulic pump on the base of the engine. that raise the engine up and down. what is it called. TRIM?? what its purpose and is this the one that needs to be lower at all time while the engine is running??

The motor that raise the outdrive up or down. is that the TRIM? and is that the one that needs to be all the way down so there will be no damage to any parts

Update:::

I clean up the Motor that raise the outdrive up/down.. put it back. still doing the same thing.. i need to assist the outdrive going up. going down is no problem. but going up is..

iam going to buy 1 motor just to see if this will fix the problem. if it do fix it i replace the other too..

it just amaze me that after cleaning the TILT mechanism it just dint work anymore.. i clean the terminal.. everything. i even put a direct positive to the motor wire and still the same..

Battery fully charged?

 

[longstand]

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

yes. Fully Fully. charged. i even charge it overnight.... but maybe the battery is not good. i will try to use the positive Battery charger directly to the motor wire and lets see what happen.. iam going to use the Highest setting. the engine start.. thats about 150AMP. is that to high...

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

I just install a fresh new TILT/TRIM Motor for the outdrive to move up or down..

same Sh!t.. argggggggg.. i check all the wiring. i check all the fuse. and while i was looking for blow fuse i found 1 blow fuse but that dont solve my problem

.. i have fully charge the battery. I even brush the battery terminal SHINY and even the ground from the battery to the engine. SHINNY> i grind and grind until i could see my self.

and yes i made sure i have a gastket on the motor, i only put one..

both of my motor for the tilt/trim dont work. it just click click. it will work if i assist it togo up......

if i assist it to go up which mean the Clutch still good. Rigth.. just a little help going up not much force . which mean the clutch for the TILT/TRIM. is Ok.

Please HELP.. I cant FIgure this out..

also. JUST TO make sure. i use a jumper cable from the positive side of the battery and connect it to the motor wire.. one wire i think is great and the other is red.. . ofcouse i did not touch both wire with the positive. just to clarify this.. but still CLick CLick...argg

Expert anyone.. before i push this boat of my drive way.. LOL JOKING

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

If you can find a parts diagram it would be helpful. There are several thin nylon washers in the TILT system (what raises and lowers the drive for trailer/water operation) ALL of these little things are important and part of the overall system. Yes the drive needs to be all the way down to avoid damage to the ball gears. I would take the 3 small bolts out of the end of the top of the tilt clutch housing (drive down or supported) and check this. There is a roll pin that can get loose and jam the shaft or break and cause the worm gear not to spin. There is a nylon washer that goes under the hammerblow, if it is not there you will have much trouble getting the tilt motor to operate properly.

Yes this is a poorly designed system, but it needs to be correctly assembled to operate properly.

The hydraulic system that raises and lowers the front engine mounts is the TRIM system. Trim down (in) to start and for sharp turns, trim up (out) to raise the bow and get more speed. Usually up (out) until the boat starts to porpoise then down a little until it stops.

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

Cr2k i have notice we have the same engine.. iam rigth.?

and i will put alot of greese .. i heard. its good to drill a hole and install and greese fittings so iam able to grees it?? what do you suggest??. i think its a good idea. plus the water cant go in because of the little tiny hole and its pack with greese..


also. seens we have the seem Engine. what do you think about my outdrive impeller pump. read above.... tell me what you think.. did i broke it or damage it... it was just few spin..

Re: V6 3.8L OMC Trim Motor is Good but Will NOt GO UP or DOwn

I have remove the 3 small bolts out of the end of the top of the tilt clutch. but i am not able to remove any more. see this picture..

also i have upload some picture of the whoe TIlt System..

here is the weird one..

Now my TRIM will not go up or down. it also click just like the TILT motor..
But my other Engine. the TRIM work. But the TILT just CLick..

i have check the fuse under the Dashboard. and replace what ever fuse that needs to be replace.. Also i have check the battery. its has 13.8 VOLTS. batter fully charge.

i even remove the Sterdrive Tilt-Gear. so there is no pressure Spur Gear..

All i hear is CLick CLick..


Assist Solenoid. what is that for. maybe thats bad. LOL because from what it sound like. it assist the other solenoid..
