Power TILT TRIM Electric Motor Differences – by Joe Reeves
The 3 wire unit incorporates a solenoid for the up mode, and direct wiring for the down mode. The 3 wire motor has a "Black", "Blue", and a "Greenish wire. Bombardment negative (-) connects to the black wire… Battery positive (+) connects to either the "Blue" or the "Light-green" wire to have the motor run in 1 direction or the other.
The 2 wire (One "Greenish" wire, One "Blue" wire) unit incorporates a complex relay setup for both the up and down mode. Via the relay system, the battery negative (-) connects to one of the motor wires, the bombardment positive (+) connects to the other motor'southward remaining wire causing the motor to run in one direction. The wires being reversed via the relay system causes the motor to run in the reverse direction.
The 2 different type electric motors cannot be interchanged "UNLESS" their associated wiring arrangement (relay/solenoid setup) is interchanged with them.
POWER TILT TRIM Electric Motors 1976 – 1992
Three (3 ) Wire Power TILT TRIM Electric Motor:
This PTT electric motor existed between 1976 thru 1981.
The original OMC function number is 387277 and supersedes up thru the numbers of 582048, 582155, and finally to its nowadays role number of 584107. It appears to be unavailable at Bombardier merely information technology might be available at Sierra under Sierra's office number of 18-6761.
Two (ii) Wire POWER TILT TRIM Electric Motor:
This Ability TILT TRIM electrical motor existed between 1982 thru at to the lowest degree 1992.
This final engagement (1992) being mentioned due to the fact that I retired in 1991 and my books simply get upwardly to 1992.
The original part number is 391264 and supersedes upward thru the numbers of 393988, 394176, 434795, with its last number being listed as 985237. This electric motor appears to all the same be available. Information technology may also exist constitute at Sierra nether Sierra'southward part number of eighteen-6759.
Yep, either electric motor is expensive but prices are not listed here as they seem to change virtually every 6 months or so.
Power TILT TRIM Won't Driblet Engine Until Trim Rams Retract:
From the extreme upwards position downward to the trim rams, the engine drops via gravity. The PTT is but releasing the hydraulic pressure between those two points.
The usual cause of this type problem is that the tilt/steering tube is so tight due to corrosion (whatever) that it is belongings the engine in the up position until the trim rams are pulled in…. then hydraulic pressure takes result.
The cure is to loosen one of the large tilt/steering nuts one/2 plow, then with a two×iv and a large hammer force the swivel subclass sideways slightly. Forcefulness grease into the grease fittings on the forepart of the swivel bracket. That should do it.
Power TILT TRIM Temporary "Downwards" Lockup
A problem that takes identify in diverse POWER TILT TRIM units is that a boater will trim the engine all the way up, so endeavor to trim it down, only to hear the PTT electric motor running and aught happening… the motor is non moving downward. The same trouble may take place when lowering the engine to its total extent then immediately trying to heighten it only not ever. And then, after waiting a short time, the boater finds that the PTT unit is performance properly once again.
This is usually due to one of the two "brawl bearing" type cheque valves sticking within the oil pump (which is located under the electrical motor). At to the lowest degree this is what I've constitute to be the case in every instance I've encountered this problem…. and it is commonly the "ball" check valve pertaining to the "up" manner.
The problem is acquired (keeping it simple) by the oil pressure jamming the "ball" into the aluminum which effectively blocks the reverse flow, then somewhen the pressure equalizes and the ball loosens its grip, the reverse pressure level allows the oil to flow past the "ball" and the unit functions once again. Many boaters, aware of the cause, merely live with the problem Withal, the cure has always been to replace the oil pump.
POWER TILT TRIM Hydraulic Lockup
If the engine has been trailered without having both of the trim rams pulled in, or trailered without even having the engine existence supported by the trailering support, it is possible for the PTT to run into a hydraulic lock upwardly. The slight up and down motion, when trailering allows over 1700 psi of oil pressure to build up on the wrong side of the oil pump. Since the oil pump cannot exceed that 1700 psi, the unit is effectively hydraulically locked into position (the elec motor runs and does nothing).
The proper method for trailering is to have the engine in a full tilt position and resting on the trailering support bracket, and so have both trim rams pulled in to a bespeak where the engine makes a jerking motion. At this point, immediately accept your finger off of the PTT trim switch. At present, speedily and sharply, tap the PTT up push button. This removes the vast majority of downward hydraulic pressure simply at the aforementioned time, the engine is solidly locked into position and cannot rock up and down.
*The Cure*
Take the engine in the upward position and supported then that it cannot fall. Expect straight at the PTT associates…. yous will see what looks like a large slotted screw on the port (left) side of the PTT assembly, merely which is in fact a bank check valve. Remove that valve and what y'all find inside which is a shuttle valve, and a spring on each finish of that shuttle valve.
After you've removed those items, look straight inside of that sleeping accommodation. You'll exist looking at the reverse side of another cheque valve. Look at the hole in the backside of the valve you removed. You will need a punch that will fit inside of that hole.
At present, place the punch inside of the pigsty in that check valve that is still in the unit of measurement, and tap it rather sharply with a hammer. It volition take quite a rap but the idea is to unseat the valve to release the hydraulic pressure. Spotter your eyes equally when you practise release the pressure, it volition take a tendency to spray out somewhat.
After releasing the force per unit area, reassemble the shuttle valve, springs, and outer bank check valve. Make full the oil reservoir with PTT fluid, having the engine in the extreme total tilt position. That'south it.
Power TILT TRIM Oil Pump Air Lock
When the PTT unit of measurement is as information technology should exist, the electric motor runs, the manual release valve is closed, the unit is full of lubricant, and nothing works, the usual problem is an air lock nether the oil pump Continue with the following.
Engine in full tilt position. Remove reservoir fill plug spiral. Insert a air nozzle up confronting the reservoir fill up hole with rags (or something) packed around information technology to obtain a tight fit. Apply simply a slight amount of pressurized air (10 psi recommended) to the reservoir. This will forcefulness the oil under the oil pump to remove the air lock. Exercise Not go crazy with the air force per unit area (fifteen psi tops!).
Editor's note: Delight be sure to bank check your engine parts diagrams or our application guides to ostend the correct parts for your motor.
