Removing the motor from a raymarine constant running pump

[Whitelighter]

The motor on my steering pump sounds like it needs some attention.
Since a new unit is over £2k I though I'd bring the motor back with me for a rebuild.

It looks like it may just unbolt and slide out - does anyone know if this is possible and are there any gotchas with the process.

Not sure if it's the same type of motor - but I split the motor from the pump on my Type 0.5 autopilot pump. All as easy as it looked, and went back together perfectly.

Looks like this

It looks like I should unbolt and slide out I guess

If you can get it to Hamble happy to have a look at it for you. Should be simple enough inside. The two way pumps are very simple.

Mine's different - but why not try it? (What's the worst that can happen? )

Thanks Trevor. Do you reckon pull the whole pump or just the motor? I reckon it's the motor that is noisy

Whitelighter,

Are you saying that that small thing you have put a picture up, cost 2K? if so wow what a rip off, I think I will stick to my small sports cruiser with no autohelm :nonchalance:

Sadly yes, that is what I'm saying. Ok, well a newer raymarine version but if it want to replace it that's the cost

I would suggest bringing the whole thing. I would expect the hydraulic end will be similar to a Vetus manual helm pump internally. I had a good search yesterday, but could find anything showing them opened up.

I would expect the main shaft will be a single piece right through the motor, so if it is a mechanical issue e.g a bearing then it is probably simpler to strip the thing in one place.

What does it do? Sorry for my ignorance, I'm just amazed at at the cost for what looks like a fairly small part. Is it full of electronics?

It's the most expensive autopilot pump. Most cost about £300-600. I don't know the advantage of the constant running pumps but I assume there is one.

It receives the command from the course computer and operates the rudders. I think it pretty basic

Ouch, I take it your boat (azimuth I think?) Won't take a different type. Let's hope you can get it fixed

Here is a manual, may hep??

Boat is a Ferretti. It may take a different type but it might involve some serious re-plumbing.

I'm hopeful Trevor might be able to reasurerect it

What's special about it is that it has a massive capacity, probably because the boat it is attached to is not a featherweight.
The equivalent part on FP can cope with a peak flow rate of 1L/min.
That beast can push almost 5L/min, with about 10x the ram capacity.

Fixing large broken machines is my day job. He who dares ...

Let me know when you can get it here. My workshop needs a tidy before I open a hydraulic pump.

What is the voltage ?

Pump is off in its entirety and in my luggage. It's a 12v pump.
Can drop it down to you in a week or so I think. Can you pm me your number?
