Force outboard tilt/trim pump

[HarryB]

I have a 1991 Force 120hp (not L) motor. The tilt "leaked" back down from the raised position (no outside leak). So I thought the check valve in the pump may need attention. I separated the pump from the pump motor and removed the 4 bolts exposing the pump. I know now, DON"T TAKE IT APART but I did. Now I need to know if someone has a diagram or can tell me where the: 3 larger check balls, 1 smaller check ball, 1 short spring, 1 longer (quite stiff) spring and 1 very small washer goes.

1) you need to remove adjustment bolt to reassemble. However, bolt cracks very often so must be replace. You need a short stub of threaded SS to replace it with. Measure existing adjustment nut on bolt so that you can duplicate. If you fail to measure then you may have to run out and buy tools you don't really want - such as a 2500psi pressure gauge.

2) the big spring goes in tall post. drop a small pair of super thin washers down hole to help prevent spring end from opening up on adjustment bolt.

3) little spring goes in the lone non-symetric hole in gearplate. little washe goes in bottom of hole. little ball bearing goes on top. use marine axle grease to hold it in place.

the rest of it varies from revision to revision. work over a bin so that none of the little parts spring to their freedom. take or draw pictures to help remeber where stuff went. It still won't work after you finish. your problem was probably in the bottom end.
