4-6-0 1189 loco

[Richard2017]

Greetings from down under
I am looking for the diagram of a 4-6-0 LNER B1 1189 'Sir William Gray' loco
I runs intermittent and I suspect dirt in the motor compartment but I am hesitant to lossen screws and open the case
Anyone can direct me to the engine diagrams so I can'see' what I am doing?
