Hi bazzo,
Being that it's a 17 inch machine you'll have no issues finding a bearing carrier. They are the same as the 14 inch machines and also the later 20 inch machines. The earlier 20 inch 45's have a hard to find larger carrier as they used a larger bearing.
Give Steve Rose at Australian Saws and Blades a call on (08)8349 7677, he's in Pooraka and I'm sure he'll have a few on hand.
Cheers,
BB.
