[FONT=&quot]I have a Volvo Penta SX outdrive from the OMC transition era (1998). I removed the drive and found the U-Joint bellows with a lot of gear oil inside. I've ordered a upper housing seal kit and a new crush spacer. I know I have to re-set pinion bearing rolling torque after replacing the input shaft seal. The factory service manual says to replace the bolt holding the pinion gear to the shaft. The OMC bolt is no longer offered. The Volvo Penta diagrams now show a complete replacement of engine shaft, u-joints, and input shaft as a combined assembly. Also, the old bolt design is no longer offered from V-P. Some comments about the old pinion gear bolt not working well.

1st question(s) . . . Should I re-use the old pinion gear bolt, using Loctite and cleaner/primer? Will the updated V-P bolt from the new input shaft assembly work? Or, am I better off swallowing the $$ and purchasing a new input shaft assembly from V-P?

I know that Bombardier is not maintaining these outdrive designs with revised parts. I will have to rely on V-P for this support as more and more OMC parts become impossible to get. My drive model # is 3868883. My transom assembly model # is 368413. My engine model # is 502BPBYC.

2nd question . . . What are the correct "cross-reference" model numbers for equivalent V-P assemblies? I assume the engine will cross over to V-P 5.0GLPBYC. The V-P drive and transom model numbers are ambiguous and I could use some help. Ratio is 1.60, single prop.

Thanks in advance.

Are you planning on replacing the U-joints at all? If so then that service bulletin seems to be more about making sure you use the new longer bolt in the new U-joint assembly which has more to do with the newer brand of U-joints as they offered GKN and Rockwell brands. More info about these two style U-joints can be found within this search of the two U-joint brands...http://forums.iboats.com/search?q=GK...Rockwell%22%7D

Being you have a 1998 drive and if still original, you should have the Rockwell type joint "assembly". If so then you'd be fine to order and install a new original shorter bolt Volvo part number 3852309 which looks to be available right here at iboats + a few other marine online stores too should it be needed. http://www.iboats.com/Screw/dm/cart_...view_id.290578 Or http://www.ebay.co.uk/sch/i.html?_fr...52309&_sacat=0

The longer bolt is Volvo part number 3860364 which is for the GKN joints. http://www.iboats.com/Boat-Parts-Acc...5568?q=3860364

looks like you've already read Volvo Bulletin P-44-1-5. http://www.marysvillemarine.com/serv...o/P-44-1-5.pdf
But if you re-read the note it talks about the new longer bolt 3860364 needs to be installed in the new style U-joint assembly.

It's strongly recommended by Volvo's service personnel that you replace the bolt and crush sleeve as both items become worn during installation.

Here would be the GKN parts should your drive have been changed over at some point, http://www.volvopentastore.com/Beari...view_id.782030
And here is the Rockwell joint parts for comparison, http://www.volvopentastore.com/Beari...view_id.782028

For engine parts, just use your number 502BPBYC, either in the iboats link below or search the number online, Find the part number you're in need of and search that part number either here at iboats store, online and in EBay for best overall results. http://www.iboats.com/502BPBYC/dm/view_id.1530449

Searching/inputting your engine and drive numbers you posted above, Your engine number added the AQ at the end for 502BPBYC (AQ). Not much info from it though, just two book manuals was all. http://www.volvopenta.com/volvopenta...on_search.aspx
