Some thoughts on what I should look for .
Boat has twin 4.3 Volvo penta 2004 . New long blocks recently installed using old external parts except starter & alternator
Knowing the spring on my belt tensioner on starboard engine was weak .
At times would make noise ( so I thought ) . Belt was new, tight
I was able too pull belt up moving tensioner pulley part by hand .
Over weeks , Noise which sounds like a rattling bearing got louder & louder .
On idle , noise sounded like a bearing noise was noticeable
More throttle noise lessened ,
Eased up on throttle loud
More throttle sound lessened
Picked up a tensioner , replaced and noise is still there Did not throw parts since tensioner was weak but noise is clearly one of the pulleys .
Engine room tight , can not bend all the way down too pin point which pulley sound is coming from
. .
I had some power steering fluid in bilge . I am thinking power steering pump or power steering pump pulley bearing ??
At this point do not want too throw parts on the blind
Power steering is operating fine , smooth and no hard turning , If pump was bad I am thinking would clearly fight me.
IF bearing is bad would still work as it should ?.
What can I look for ?
Remove belt , Hand turn power steering pulley and hopefully hear some noise ?
On my boat power steering pump is connected to steering actuator off starboard engine .
Port engine has a power steering pump with pulley but no hoses ?? Mfg install PS on all engines .
Never checked but when I return too boat will check
I am assuming fluid whole openings are plugged
Pump Has fluid .
THINKING swap ? If the internal pump connected too actuator is NG , Swap , the pump acts now as a pulley like the other and might fix the problem . ??
Run PS off port engine with longer hoses but by the time I MCDYVER I can install another pump
Best way is too test each pulley off crank shaft with a adjustable make shift belt process of elimination
Engines are 4.3 GXI B , what other pumps can I use ?? Can I use a mercruiser ?
Some thoughts and ideas too resolve this issue
THANK YOU AS USUAL
