Title: Internally Balanced Crankshaft?
Post by: 1.6Lmarine on April 30, 2026, 04:53:52 am

Good Morning,

Just a quick question today.

Is the crankshaft on a 1.6L TDI ME from a 1987 Jetta internally balanced?

Thanks so much!

Craig

I am not sure what that means.
 It is balanced.

In 1987, VW Jetta was not offered with any TDI engines, only IDI. However, it seems that you may be asking if, for a Jetta TD engine, an EXTERNAL (weighted & indicated as to position) damper or flywheel is needed to achieve a balanced reciprocating assembly (as is common on many Detroit-built domestics). AFAIK... No. They are all supposed to have the INTERNAL components balanced together. OTOH a $erious performance assembly, especially one intended for high rpm service, could include any damper/pulley, as well as the flywheel & clutch assembly in the balancing process.
