QuestionQUESTION: Hey Ron,
The old flywheel has three blades on the outside edges, and the other one off the 450 dose not. Is this going to be a problem?
Can the car run without it (reference sensor). Or will the car run with the 450 flywheel sense it is different.
Thank You Lerrie
ANSWER: later models I believe took the signal from the transmission. Earlier sensors are different. and pick up from front of engine
What year is the flywheel you are wanting to use
If you need to find TDC for timing ect,I would think you would need the sensor. I think however it will run without it , if you are lucky enough to get everything timed correctly
Again < i have never done this, so I am venturing my best guess on all of this

QUESTION: It's me Ron the other car was a 1985 BENZ 450. I was looking for the mark on the old flywheel, it was a dot and the torque converter had three small dots do all three have to be lined up together?
Answerwe may be talking about different things - the mark you are seeing on the old flywheel may be the witness mark , or the mark to be lined up to the crank, for balance .
Some flywheels were balanced to the engine others balanced to zero. these marks are usually very faint and hard to find
one of my cyber friends had this to say about another similar issue, perhaps this will help ( or confuse :) )
All of the engines that come in the 123 chassis AFIK will be neutrally balanced on the crank and the fw IF the crank can be balanced without the flywheel. HOWEVER, if the crank cannot be balanced by itself, the flywheel will be added to it and the assembly will be neutrally balanced.
There is no way to know what your situation is except to take the flywheel that came from the crank that you will be using and check it for balance. If it is neutrally balanced you just put on a flywheel that is neutrally balanced and you are golden.
If your crank's fw is NOT neutrally balanced, the fw you plan to mate to it must be match balanced to it. If you do not have any marks then you have twelve possible placements....eleven will be wrong.
trying to match a balanced flywheel to a different engine may be a pointless task,give it your best guess, i also think the torque converter does not come into the balance equation, it is after all filed with fluid and self balances
