86 Johnson 140 wont tilt/trim down

[boydog40]

my 140 trims and tilts up perfectly but when I hit the down button the motor runs and the tilt cylinder will not pull the engine down until the trim cylinders ahve fully retracted then it will trim all the way down - weird huh?<br />no leaks and fluid is full

Welcome Rett.....know Scarlett by chance???? <br /><br />Sorry partner...couldn't resist....<br /><br />Anyways...that's the way it works....trim cylinders in first and then the tilt cylinder.<br /><br />It's working OK....

believe it or not I married a Scarlett!!!! nahhhh just kidding - thanks for the reply but???<br />Im confused, when I hit the down button the motor just sits there and does not tilt down - then when its time for the trim cylinders to kick in then the motor starts to drop - it should tilt down to the trim cylinders and then trim down - right?

OK rett....think I know what your saying....I hope....<br /><br />When the engine is all the way up, and you hit the down buttom, the trim cylinders go in before the tilt cylinder let's the motor down.....is that right?<br /><br />I was thinking the engine was being supported by a transom saver.....

Re: 86 Johnson 140 wont tilt/trim down

you are correct sir<br />the tilt cylinder is not pulling the motor down, only trim cylinders (when it gets to their turn) will pull it down<br />I am at a loss as to whats wrong b/c it works fine going up - fluid bypass? trim motor only reverses direction in down position right? looking for a repair manual now.

Re: 86 Johnson 140 wont tilt/trim down

In the down mode, the engine drops down due to a lessening of hydraulic pressure in the tilt cylinder and gravity. When the engine drops to where it hits the trim cylinder rods, hydraulic pressure takes over, pulling the engine inwards.<br /><br />Your problem is caused by salt, corrosion, rust, whatever, being accumulated in the steering/tilt tube area. This prevents the engine from dropping via the gravity route, and the engine stays in that position until the trim rams are hydraulically pulled in, then pressure is applied at that point to the tilt cylinder.<br /><br />The cure is to loosen one of the large steering tube nuts about 1/2 turn. Carefully using a 2x2 or 2x4 and a large hammer/mallet, tap the swivel bracket sideways a few times (back and forth sideways). Grease the grease fittings on the front of the transom brackets that surround the steering/tilt tube. That should do it.
