OMC Stringer Trim Pump diagram

[mrlassi1]

Can anyone point me to a diagram or picture series that details how to reassemble the trim pump out of a 1976 OMC 190 (Ford 302) Stringer drive?

My pump motor was bad. I pulled the bad motor but but could not get the replacement motor's shaft to engage the drive gear in the pump. When I broke the pump down two BB sized steel balls, one smaller (than a BB) sized steel ball, and a tiny spring fell out of the pump.

I have the Seloc Manual, but it does not have a diagram of the pump. I've looked back through the iboat threads, but have not found anything.

Your help is appreciated.

Partial success. I was unable to find a diagram so I put it back together placing the two BB sized balls in the valve slots on either side of the drive gear. I placed the spring in the hole at 6 oclock and put the small ball on top of the spring.

After putting it all back in and testing (I fit the motor shaft to the drive gear with a little filing). The unit will raise, but not lower. Guess I put the spring and small ball in the wrong order.

Next I'll try it with the small ball in first and the spring on top.

Do you know the brand of the pump, model number etc...?
