looking for complete horizontal head for 600SS---yep the wood ruff key has worn and i have play on the pulley and cam--this happened earlier in the year to the vertical head---i have temporarily fixed/bodged with a spot of weld and tab washers and locking bolts and loctite--- and also devised a decent locking tab system on the pulley nut for the vertical head to avoid this happening again---i check these pulley nuts regualarly, like weekly!!-noticed a drop in power (ok ok what there is of it

)yesterday and some slight vibration guess this was the cause of that--any help very much appreciated
