automatic flywheels - oel_brenner - 12-26-2009
so on my W126 project, the 3.5L engine came out
(1990 350 SDL)
and had what I expected for a flywheel:

but the 3.0L donor engine that came out of a
(1987 300 SDL)
had this one:
![[Image: IMG_0566.sized.jpg]](http://www.coastalboatsales.com/jfraley/gallery/albums/The-W126-LWB-project/IMG_0566.sized.jpg)
weighted.. not like a manual car, but certainly more mass then the other one..
which do I use ?
does it matter ?
pros cons either way ?
anyone else seen this weighted one ?
I am a bit of a 126 noob.. never seen this on a 124

Interesting. How do the torque converters compare in mass?
The heavier one will give a bit more off the line torque but the lighter one will allow the engine to accelerate faster.

well from outward appearance they look identical
part number on the 3.5L converter:
(this trans has been re-built / replaced very recently)
124 250 0302 0690
part number on the 3.0L converter (87 126):
126 250 2302 2287
just for reference.. part number off converter that came out of my 87 124
126 250 2302 4586

yeah, I figured that.. the heavier one I think will be good for the wife's
daily driver, probably more "drive-able" around town and whatnot..
RE: automatic flywheels - oel_brenner - 12-27-2009
test fit the convertor that was already in the car against this heavier flywheel and everything seemed to fit fine, so I wound up using the heavier flywheel that came on the 3.0L.
engine is in, bolted up.. and most of the major stuff hooked up.
I will finish up tomorrow and take her for a test drive..
stay tuned.
