Dolphin motor repair

by DM

Dolphin's motors are very expensive, so is a rebuilt as far as you can find them.

However most of the time the motors can be repaired. The spi seals leak after a while and some water get into the bearings that rust.

It can be that bad that the propeller cannot be moved.

Most of the time the rest of the motor is in good shape. You just have to change the spi seals and the bearing and it works

I would add that this operation needs to be done every 2 years. I was operating the robot each week since 3 years in salted water when trouble started with very short operation time (around 1 minute)
replacing the seals solved the problem,but there is heavy corrosion on the shafts!
