Thanks @muc. Per your longer reply, I'm not too worried about U joints or a gimbal bearing in a dry DS bellows. VP recommends changing this @ four years. I'm getting due, but have to fab up an adapter for my chain hoist to pull the drive. ....long swim platform complications. Alpha II was all...
Makes sense. My local shop rate is $150/hr. Likely $300 for the R&R. OEM assembly $700+.
I've replaced Alpha II Unis several times. Hydraulic press, plates and two different size sockets should work on a VP drive shaft. New crush sleeve and cap screw are peanuts.
Sierra and GLM have substitute...
I'm a long way from needing major repairs on my VP drive, but I've been checking the manual, special tools etc so I'm ready.
Volvo Penta Shop and my drive manual both say the U joints aren't replaceable. I'm having a hard time swallowing this.
Is it true?
Is there a VP p/n for these Unis? ...or...
A few years ago I bought a prop with a RubX and was using a 1/2" drive ratchet with the drive in gear to set the hub. I was surprised when I turned the prop shaft in either F or R. The plate clutch was slipping. I know my 250 hp 4.3 produces well over 300 ft/lb torque and I didn't come close to...
My pal is replacing the points on one of his Cruisers 350 cu in SBC engines with a hall effect replacement. He's asked me to help him time the engine.
If I can get him to get the engine s/n before then I will. Otherwise we will check the current timing one each engine an hope this is correct...
Thanks again @muc.
I wasn't farting off your details. I've followed you since I joined the forum eight yrs ago. I have tremendous respect for your knowledge and diagnostic skills. I was on a tight timeline trying to get good data between weather, feedback intervals and retests before I handed it...
I had a break through today. New battery a few days ago. After changing the three port plugs and the #2 plug, which was also dark varnished like #1 (I threw in the towel trying to get the boots off #4 and #6 in very limited space, but hoped they looked as good as #3 and #5)
The boat jumped out...
Thanks for the get back @muc .
Update, I followed your advice and installed a new cranking battery. Significant improvement. Cleared codes and reran .rec files. No alarms, MIL lamp or codes when finished. Very little engine vibration.
No change in performance. ...low power.
I changed the port...
Latest .rec files attached. I cleared and verified all codes were gone.
I couldn't find the pick on Diacom to clear misfire data. I Googled it for Diacom and found a member on a different fourm who said to go the 'Tests' tab and select clear misfire data. It wasn't there, just various system...
