Servicing a Raymarine ST2000

[DuncanHall]

I have found my autopilot has got worn gearbox. I have obtained a service kit but have no instructions. Has anyone experience of servicing these units. The particular problem I have is how to press on the new small gear on to the motor shaft. It is a tight fit and forcing it on May damage the motor. Preheating may be a solution .

If you got the service kit from Raymarine, try asking them. They're usually most helpful.

What ever you do, don't try to remove the big brass nut from the leadscrew. Many essential ball bearings will fall out.

I think the gear is just a push fit on the motor, but support the motor shaft when you're pressing it on/off.

Why not tell us all?

Thanks all. It's now reassembled. I used a vice and a spacer bar to push fit the small cog on the motor spindle. It was a tight fit but I guess that's the design intent. I added a drop of locktite on the spindle taking care not to fix the bearings. It's all back together and runs much smother.
