Advice please on boiler fan unit - Ideal Classic SE15

[Doc955]

I'm hoping someone can help me with this:
Is it possible to remove just the blower unit from the boiler without too much hassle? I want to be able to get at the lower bearing in the fan assembly but I need to get at the underside of the blower so I can get the impeller off the motor shaft so I can get the shaft out from the top (if that makes any sense!). I can't see an easy way to do it without removing the entire assembly from the pressure vessel. The 'snail shell' part of the blower is seperate from the rest of the assembly but I can't see how to get just this part off.
The reason being is that I had an incident with the fan motor/impeller bearings drying out over the weekend (started with an 'orrid noise then stopped completely yesterday) After letting it cool I was able to get some lube into the bearings and this seems to have cured things for now, but I think it will recur sooner rather than later. I begrudge paying £90 for an entire fan unit when I know the problem can be solved with 2 bearings that are about £2!!
Many thanks.

Classic SE FF
1. Issolate from electrical supply.
2. Remove the 2 silicon rubber tubes from the fan sensing points.
3. Disconnect the fan leads.
4a. Rear flue. Slacken the M4 screw securing the flue connector to the
fan. Disconnect the connector from the fan and slide into the flue.
4b. Side or top flue. Slacken off two M4 screws securing the flue elbow
and flue connector. Disconnect the flue connector from the elbow
and slide into the flue. Remove the flue elbow.
5. Disconnect the silicon rubber tube from the rear of the collector hood.
6. Slacken the two M5 nuts on the front tie rods, releasing the tie rods
from the combustion chamber.
7. Remove the M5 central fixing screw at the rear of the collector hood
and remove collector hood / fan assembly.
8. Remove the three M4 screws retaining the fan to the collector hood.
9. Fit the new fan and reassemble in reverse order, ensuring the fan
leads and 3 sensing tubes are reconnected.
10. Check the operation of the boiler.

Many thanks. It seems it is as simple as it looks.
