Hopefully this is an easy question. I fitted my flywheel last night and this morning I noticed I'd managed to fit it without aligning the dowel hole to the crank. I've googled this a little this morning and struggled to find a definitive answer to whether it's a problem or not.. Is it important to have this hole lined up?
As I understand it from googling, the hole is for an alignment dowel, and possibly might have been used on corvettes that have a matched flywheel (with weights added to balance?) however on the camaro/firebird applications this isn't the case.
So by that logic the flywheel
orientation isn't important? I wanted to get some opinions before I go ahead and bolt the clutch to the back of it tomorrow. The flywheel bolts are torqued up and loctited in, so I would prefer to leave them that way if it's not an issue. Picture below
IDK id you motor is "neutral" balanced but if it is and the FW is also neutral balanced...it does not mater the mounting orientation
If however it is a rear external balanced motor...than yeah FW orientation matters
Hi, thanks for the quick reply. It's just a standard LS1, no additional balancing completed.
I'd guess normal Camaro LS1s are internally balanced and the flywheels are neutral? Is that right?
