0mc 800 outdrive tilt gear adjustment

[Willemdb]

Hi
I have a 800 omc outdrive and the tilt dousnt work because the gear and half moon gear our binding. I'm wondering if there is a way to adjust them closer together or if I would just need a new set of gears
thanks

Welcome aboard.

If those gears aren't meshing properly, I would check the connection of the drive to the trunions, and the quadrant gear being properly mounted to the drive. If those are both fine, and the quadrant gear is straight - then I would suspect something is wrong with the clutch pack.

Are you sure that the tilt motor is getting enough current to operate?

I mean the tilt quadrant and the quadrant gear seem to bind. There seems to be to moch space between the tilt quadrant and the quadrant gear so I was wondering if the tilt quadrant could be adjusted Dow so it meshes properly with the quadrant gear. The clutch is good because I just took it apart and cleaned it.

How much current should it get

Here ar some pictures so you can see what I mean

I guess my point is that the quadrant gear is a pretty stout piece of metal, that's bolted (with some not-so-sissy bolts) to another rather stout piece of metal. Assuming they're bolted together properly, then there's no reason the teeth of the clutch gear shouldn't meet the teeth of the quadrant gear.

If the drive isn't seated on the trunions properly, it's possible there's enough off-kilter to separate those teeth a little. I've done that once in the past.

If the drive is seated properly, then you wind up with a few options: the metal of the upper gear case is messed up. The metal of the quadrant gear is messed up. The clutch gear is messed up. Or some combination of the three.

To me those photos suggest something isn't situated correctly, or something is bent/messed up.

I think I'll have to try get a new tilt quadrant and gear. The teath on the tilt quadrant do seem a bit chewed of but it still seems strange that they don't mesh properly

Hi, you said you had the clutch out to clean it how did the seals look? I was thinking if the seals are toast then maybe that would cause the clutch gear to get pretty sloppy. Just my 2 cents, 10 cents American. Cheers

I dont think you have a quadrant gear or pinion gear issue.

I think you have a gear box casting issue

looking at this picture, it looks like your clutch housing broke at one point in the boats life and someone welded it back together

Where the quadrant gear is mounted on the upper gear case does it look like that area is cracked or has been welded ?
Can the small gear be moved up and down as if the housing is worn where the shaft comes through?

I bought the boat last fall so I don't know if it has been welded before.

I wonder if its missing the round metal pieces in the trunnions ? sorry for the terminology , I am sure Kenny knows the right name . But when you take the trunnions off , there is a flat metal piece with holes (basically a liner) I wonder if one side is missing , throwing off the alignment ?

that looks to be bad , I am assuming this would chew threw the ball gears and break something fairly quickly.

Edit , found a pic . These things

That is a good point Redrig, you just never know what has been left off the last time someone fooled with it.

Thos are in there because I had the hole outdrive off but the problem was there already before I took the outdrive off

get more light under the drive and re-take the picture in post #11 with lots of light to eliminate any shadows. if that is a weld bead. you need a new gear box
