My serial number for my outdrive is 3102129444 and my motor is 4100135372.
My flywheel housing is red and has a grease zirc.
If your flywheel cover is red and has the grease fitting, someone has likely replaced it.
I'm wanting to replace my pds bearing(s), seals, snap rings, etc... Looking at a diagram, they also show a bushing on the Engine side of the shaft. Is this a good thing to replace at this time as well?
If (key word "if"), you have a double bearing PDS, this will NOT apply!
However, if (key word "if") you do have a single bearing PDS w/ a pilot nose, that bushing does NOT undergo any rotational contact with the PDS pilot nose.
They both spin 1:1 at all times.
It is a pilot nose-to-crankshaft centering device ONLY.
Here is the OEM 430B flywheel cover and PDS.
Volvo Penta Exploded view / schematic Flywheel Cover, Primary Shaft and Clamp. Ring Kit, Drive SP-C, DP-C 430B, 431B, 432A, 434A - MarinePartsEurope.com
Note that this one is a single bearing PDS with a pilot nose, and w/o a flywheel cover grease fitting.
It also requires the pilot nose crankshaft installed centering bushing.
This PDS will come out AFT without engine removal.
Again, if your flywheel cover is red and has the grease fitting, someone may have replaced it.
If red, and if it has the grease fitting at 12:00 O'clock, will likely be a double bearing PDS and with no pilot nose or pilot nose crankshaft centering bushing.
If so, this means that the engine needs to be removed in order to access the FWD PDS bearing/seal.
I'm also wanting to replace the U-joints
(bearing crosses) and associated seals at the transmission as well as the o rings for the dipstick and drain for the outdrive.
Good call!
The bearing cross p/n will be determined by the fashion in which the trunnion bearing caps are held in place..... i.e., internally or externally clipped.
Lastly, I'm thinking it would be a good idea to replace the bellows.
Universal Drive Shaft bellows???? Absolutely!
Exhaust bellows..... unlikely!
I'm finding that part numbers are all over the map for these items. Any help with parts store cross reference numbers and/or kits would be appreciated.
Pictures will help determine which components you have.
So, my questions are:
1) Do I have the 2 bearing set up and if so, do I need to pull the Engine? If so, any suggestions or tricks you could pass on?
See above!
2) I'm reading that to replace the U joints
(bearing crosses) , there is no need to remove the entire outdrive, rather just the upper gear box. I have the OEM FSM, but am a little fuzzy on the bearing run off procedure... Any help here would be appreciated as well.
Again, pictures will be very helpful, and will allow me to tell you whether or not you have a Pre-A transmission or a A transmission.
