Subject: [FlyRotary] Some things to check was Re: [FlyRotary] Acceptable oil pressure

Apart from a leaky pickup gasket,  or if the bolts were left finger tight (you have to be REAL careless to have this happen)  it is possible to have a fractured oil pickup pipe (rare but it can happen),  I've also seen blokes leave the oil pump bolts loose (again usually finger tight!),  or not stake the oil pump shaft lock washer (just carelessness),  or the Woodruff key wasn't located correctly (Ed's issue! - REAL easy to do - happens to me about every second or third engine).  Sometimes it takes two or three goes to get it in. They are real small & fiddly You must ALWAYS double check - use strong light or a torch to make sure that you can see the key is in the correct place once the sprocket in on on the shaft,  before fitting the nut & lockwasher. 

 

What would the symptom be if this wasn't done right? Don't remember having a problem getting the oil pump reassembled, can't be sure now if all was done correctly.
