The plate behind the impulse weights may need to be removed & reinstalled 180 Deg to convert the mag to upside down operation. Also need to check that the rotation is correct for your tractor.
Johncat07,
At the magnetos the same? Some of the D6's (early) had horizontal mounting and other (late) had the mounting at a slight angle. See pics. I don't think you can just rotate the impulse. You would be changing when the impluse winds ups and releases in relation to the points on the breaker plate. Becuase as you move the body of the mag, you rotate the breaker plate and points in relation to the cam on the shaft. :confused2: If you have a D6 8U you are probably looking for a Bosch MJK mag. There is an Eismann that looks like it would work , but the impluse only works if the mounting bolts are horizontal. This one is for the erlier D6's like a 5R.![]()
I can only relate to the AB mag but I suspect the Eisemann is similar.
The impulse couplings are not the same for the early and late D6 and only a few parts are interchangeable and none are adjustable.
The impulse event start is based on gravity so the arrester plate slot has to be on the bottom. To obtain this on the slant version the housing (spring), Hub and arrester plate are different.
My list of Eisemann applications and AB interchanges doesn't show an Eisemann application for the late D6, just the RC-2H for the early units.
the magneto mounts at a slight angle.both magnetos spin in the same direction. both have opening in arrestor plate at bottom. both magnetos are bosch mjk the one fitted is 412360B-410 and the replacement is 4/2306C-410. the little slide weight seems too lose it just falls out. if you place the magneto in any other position it will spin without the problem, but you hear the slide weight scraping around inside of arrestor plate.
Will the coil and condenser from the new mag fit in the original one? If it's the same make and type of magneto that may be the easiest way to go.
Those are the correct mags for the later D6. Have you had the unit apart to check for damage of the hub, weights and cam?

(new mag second pic from right, old fourth pic from right)
removed couplings off both magnetos, weights and plate all facing with letter C up. and the letter A down. however on replacement mag the plate was loose from coupling, so i placed in back where it should be same problem. i noticed on old mag the arrester plate has a gouge where the weight catches on replacement. ( as per photos ) i then flipped weights and plate in replacement mag so the letter A was facing up. seems to work, still heat the small end of the weights scraping but when fitted and running i imagine the weight would slide towards the larger/heavier end eliminating the scraping.![]()
