Thank you Ricardo!
You are very welcome!
I will try to answer your Qs.
(1) yes I was referring to the top gear box of the transmission,
The very upper unit is the "transmission"!
I did this first so that I could check the
Bearing Crosses and inspect the tail area of the Flywheel cover.
(2) exactly the reason I purchases new PDS bearings and seals, even though I would bet the current ones are fine, I installed them myself when I put the new engine in, from what I can tell, I did it correctly, I haven't removed th PDS yet, but the shaft turns smoothly with only the grease resistance, seals appear clean. There is no back and forth play in the bearings, and no side to side play.. they are 60 hrs old.
That sounds good!
(3) the new parts that I have ordered are.. new
Bearing Crosses. (Moog) new seal behind the x bearings.
Please explain seal behind the x bearings!
New PDS bearings, seals and snaprings. Drive line bellows. I'm going to replace everything once again. The Bearing Crosses and gear box seal was replaced by the shop. They appear and feel new, the bellows are dry.
(4) as for tolerances checked by the shop, I do not know, the receipt only says ( new Universal joints and seal installed,new shift mechanism shaft seal, new O rings, tolerances checked drive resealed and pressure checked. (This was done about a year ago and the cost was at $932.00 (not that that means anything)
Ricardo, I am leaning to believe this may well be an issue with the bearing box... although it does only make the noise while turning, in either direction, straight forward it is silent.
As I've said....... I do not believe that the BB is causing this.
Let's look at it from a gear set's prospective.
If you were a well designed hypoid gear set, and if you were first-in-line for a several hundred horse power reduction, and if bearings were questionable and if your tolerances were Out-Of-Whack enough to cause an audible noise....... how long would you last under these conditions before you "self destructed" ?????
Another possibility:
As the drive articulates (Port or Stbd turn) a side-load force is created that will push the Main Suspension Fork more firmly against the Transom Shield.
This alone will cause a change to the way in which normal and acceptable vibrations will transmit themselves through the stern drive components!
There are a couple other things that I should point out, when shifting into gear, forward or reverse, at idle, there is a clunk noise, are volvos a silent shift?
The cone clutch engagement itself will be very silent.
However, when the propeller begins to pull AFT-wards, the thrust wants to raise the drive UP.
If your latch hook points are not crisp and clean......... that is likely causing the "clunk" that you hear.
As I mentioned, this is my first Volvo drive, Mercruiser Alpha 1 has an inherent shift do to the gear cut and needs a shift interup switch to allow the gears to disingage..
That is correct...... and it is a silly feature but it is necessary for a Dog Clutch system!
Volvo does not...correct?
Correct!
The shift shoe groove in the sliding sleeve is cut eccentrically.
This eccentric cut causes a mild hammering affect as the shoe attempts to disengage the sliding sleeve from either gear cup.
i have checked the reverse outdrive lock, it works fine, my idle is at between 600 and 610 on digital tack. It's a carbureted engine. There is also a left hand prop installed, originally it was a right hand but I installed the left as it was brand new ( I followed the instructions under the cover to do their)
Could this clunk while shifting noise be the exsesive vertical shaft play?
My I assume that you are referring to the transmission's vertical shaft?
If so, I would have to say NO!
Also seeing I'm going to be tearing this thing down, I would like to buy one of your replacement split ring keepers..how do I go about getting one?
You would shoot me a PM with your info!
would gladly love to have you do a complete once over on my sterndrive!! But the shipping would be the killer.
so it looks like I will become to know my Volvo Penta personally well.. not a bad thing, just another project along with the many I allready have.
this is me (
www.boreallodge.com) it'll explain my location difficulties.
very appreciative of everyone's advice here! My wife and I only have short windows to be able to enjoy getting out on a boat, it's best that it works the way it is suppose to!
