Engine interchange ?
 

CLK430 M113
Is the basic engine from 1999 to 2002 the same? I would think a few bolt on things maybe different, has anyone done a swap from the older to the newer? Just curious.

I also have a problem when putting my top down on my 2006 CLK350. The operation all goes smoothly until the last step when the bow flippers (top storage compartment cover) come down to lock, at that time the flippers do not seem to want to go down in place until they snap down in place. I think these flippers should nest in place but they seem to either bind somewhere or there is not room for them to go down. Any comments would be appreciated since it is almost top down season. By the way when i put the top back up they bow cover flippers do not seem to bind anywhere and they nest in place fine.

Benzfan2018.....your post may not find other replies, because it's posted in the wrong forum (your 2006 clk is a A209 model and this is the A208 thread), as well as being a mistitled thread.

That said..........

The flaps, are part of an assembly (e.g. includes the flap, a bracket and a mechanical cable).

The flap is attached to one end of the bracket, with the other end attaching to the soft top cover. The bracket is made of sheet metal and has a spring loaded hinge. Additionally, one end of the cable is attached to the end of the flap and the other end is anchored inside the compartment storage area.

When the soft top compartment cover opens (e.g. to 90 degrees vertical), upon either opening or closing the roof, the cable becomes taut, which folds the flaps downward, about 90 degrees. After the rear bow completes it's movement, the compartment cover lowers, unloading the cable/spring tension and the flap returns to it's normal position. The purpose of the flaps folding, is avoid a potential collision between the normally extended flaps, when raising or lowering rear bow. It's a very simple system, none of the components are ever under high stress, which explains why no prior flap problem posts were found.

My suggestion would be to check that the brackets have not become bent, because if so, the cable may not fully release the tension to unload the spring hinges and/or spring end stops have moved, keeping the flaps from aligning with the adjacent panels.

And really what in the world does a convertible top problem have to do with swapping an ENGINE? Reading and comprehension problem?
