I have a L4202DT kubota with a side mounted harmonic balance on a VT1502 Engine.
The previous owner has played around with this balance and I am not sure it has been set up correctly.
The give away was broken bolts and cross threaded bolt holes.
I am in the process of reinstalling this balance, there are factory marks on the gears inside the balance so I am assuming the weights are set ok.
The issue I am facing is the factory marks on the main drive gear do not seem to lineup with anything. I have ordered an Engine workshop manual but I don't think the harmonic balance is covered by the engine manual.
If anybody has an information about this dynamic harmonic balance it would be helpful
