I reread what I posted, HMMMMM it could be confusing that I just swapped the FW`s w/o getting them balanced.

OK, I had the FW`s balanced at a machine shop that has the balancer that spins the FW`s to compare the two. Then if the new FW is off, holes are drilled to match the weight of the original etc... if they are natural balanced, no problem, but having two FW`s that are natural probably not common, who knows? I have done this two times, once with a 240D FW and once with a 300D 617 FW.

The machine this is done on, is used in a Hot Rod Shop that does a lot of high end big $$$ cars.

I also have a pile of FSM`s. in the Service manual Engine 617.95 Turbo Diesel, it states. section 03-440

The engine is fully balanced, that is, the complete
engine has been balanced on a balancing machine.

Since in the event of repairs this type of balancing
cannot be preformed, while on the other hand the
balanced condition of the engine should be main-
tained as much as possible, a new flywheel must be
brought to the same balancing condition as the
removed flywheel.

Static balancing of flywheel

1. place old and new flywheel one above the other
in such a manner that all the bores are in alignment
and both coupling surfaces are facing in one direction.

2, Insert balancing mandrel and screw-on new fly-
wheel offset by accurately 180 deg in relation to old
flywheel.

3. Permit balancing mandrel with both flywheels to
swing on rotating device to stop.

4. If an unbalance is found, drill as many holes on
heavy side on new flywheel as required until the fly-
wheels will come to a rest in any position without
swinging.

Attention!
The hole circle dia., the drill dia. and the max. drilling
depth must be maintained.

Yes, that is what I was referring to....
the rather low tech FSM method..
your machine shop probably has equipment that is ten generations advanced from the directions in the manual ... which allows a good auto shop to get pretty close...

It`s old technology that works, and has worked of alooooong time nothing new
Like a bubble level for balancing a tire, worked for a long time before they
got sophisticated with spin balancing the tires. it is bit more precise.

I don't follow your reasoning Greg. First you say that people need to look in the FSM =>

Then you say the FSM is not so good after all

I agree with Charlie =>

It is old school technology - but don't forget that static balancing is the first step to ensure a dynamic balanced system.


I agree, however, that a decent machine shop should be able to balance it better but I understand that many shops will only bother with the next noticeable harmonic - not everyone does a Tirpitz propeller job!

Don't leave that there - I'll take it to bits!

Where did I say that ?
I said people needed to consult it .
I said people can get lucky.... if there are 12 possible ways to install the flywheel... you have a one in 12 chance of getting it pretty close
I said that Charlie's machine shop may be equipped with machines and knowledge which allows them to do a good job.

and if you look at your post ... you do the same thing.... people ought to use all the knowledge and resources they can given how much trouble it is to take it apart to redo or fix....

It only requires a mandrel and Patience. It does not require electricity, a lathe, a computer or advanced training ..... therefor it is low tech.

Round and round and round we go
