I finally got all the blades disassembled – two of these were relatively straight forward and with the instructions from various sources (thanks Eric and Alexandre) the hardest bit – getting the thrust bearing race on the blades off – was eventually straight forward and the blade races on two of the blades just dropped out. The third blade was a different story - interestingly the one that I on reflection have never been able to push grease in through the side grease point. It was a complete nightmare and needed some extreme measures to get the bearing race out (eventually in pieces) – it turns out that it was the race that should be in the hub not the blade and therefore being and exact fit to the channel in the blade was blocking the grease from getting in (hence my confusion on initial inspection) and had seized in place. Getting this out was not without some damage to the blade but I think it will survive – This prop is 10 years old and I don’t believe has ever been serviced so the bearing races must have been put in upside down at manufacture.
Anyway I think the statement in the assembly instructions;
“4. Now fit the thrust bearing (#9), into the blade and hub. Note that the races are of different inside diameters. IMPORTANT...Fit the largest inside diameter race into the blade. If not fitted correctly you will restrict the grease flow into the propeller. Place the captured balls & race into the hub.” - is VERY important.
