Can any of you guys with 28's and Volvos coupled to Hurth HS63A or ZF63A gear boxes comment on whether or not you notice noises associated with shifting into gear?
I just had my stbd gear box replaced under warranty at 300 hrs because (a) it was making a clattering noise when first shifted into fwd and (b) I found a small amt of metal shavings in my oil filter. Problem is that after 4 weeks in the yard and a lot of $$$ I had to chip in above what extended protection would cover, I hear the very same noise with the new gear box. stbd side makes the noise going into fwd and port side makes the noise going into reverse. Other directions are silky smooth on both sides. Noise is only noticeable when maneuvering around close quarters, ie - moving slowly so engines are quiet and shifting a lot. No performance issues noted.
