Re: Volvo Penta 3.0 L GSM-C engine replacement
Wizard, I think that you'll see that there is NO debate once you learn which drive system we're talking about.
My comment regarding engine removal without pulling the drive, is for the main suspension fork/pivot tube geometry AQ series engine/drives.
Your drive is a Gimbal System drive. Apples/Oranges.
With the AQ series, engine alignment is pre-determined via the engineering.
IOW, the F/C, the PDS and the Engine can't help but align when connected to each other.
However, we do one initial alignment between the F/C and Transom Shield duing intial or original engine AND flywheel cover installation ONLY.
After that, and when/if the F/C is not removed, a simple engine pull AND engine re-installation (while leaving the F/C in place), is very common.
(this may require attention to the front engine mounts in that they are not left to be mixed up from side to side, or left loose to allow a height change)
When the mounts themselves are un-touched (stringer lag bolts removed), the engine block castings are machined closely enough, that this is seldom an issue.
Now... if someone suggested that a Gimbal system drive engine can be pulled without removing the drive..... they are correct, but with several caveats.
One caveat would be if you have space to slide the engine forward enough to allow the drive shaft to disengage from the drive coupler.
Another caveat would be that you fully understand that this is for engine removal ONLY.
When going back in, the drive MUST be removed in order to perform the drive coupler alignment procedure.
I would take Bill's advice, and go through the entire engine drive coupler alignment procedure.
You DO NOT want to loose a coupler due to a silly misalignment boo boo.
