Alingment W/extension boxes??
 

I've seen several threads,that every so often you should check the alingment.Is this still needed if you have extension boxes?????I have 12" Stellings,that I think are set on the bottom hole.If need to,what are the procedures.
Thanks

The stellings still uses the original merc transom assembly with a center bearing replacing the coupler. Becase of this, the alignment is still the same as the normal alignment proceedure. Get the merc alignment tool and jiggle the bearing/transom assembly around until the tool slides in-out with 2 fingers. Most people should check this every other year.

Because the IMCO system reuses the stock coupler, the alignment point is further forward, thus requiring a special alignment tool. Otherwise the procedure is the same.

Now if you have multiple engines, there is also an alignment to control the amount of toe between the drives. I believe that the correct setting is to have the drives equally pointed in 1/8". Somebody please confirm that number.

Cord,
I've seen the center bearing that you referred to,when I removed the inspection cover to grease the unit.The bearing looks similar to a pilow block set-up,Is this what I need to move around to aling it??? Or do I still need to raise or lower the motor????
Thanks

No, the motor does not move. The adjustment is split between the bearing that you spoke of and the gimble assembly. The holes for the gimble are oversize and allow some movement-that's assuming it didn't get glued on. Try to adjust the bearing first, then go to the gimble if you can't get it.

I had the "pleasure" :mad: of replacing a
drive shaft on a stellings assembly, due to a
failed (engine side) u-joint, updated shaft
assemblies were installed.
as i recall, there were shims that went
between the housing (extension box) and
the carrier bearing mount .
after changing out the drive shafts, i
installed the carrier and the shims in the
original location, left the carrier bolts/nut loose
enough to allow some movement, slid in the
alignment tool, snugged down the fasteners,
rechecked alignment, it was ok, tightened down
the fasteners, recheck, ok.
if the fastener remain tight, i doubt there will
be any alignment problems.
what you DO want to do is keep the u-joints
and carrier bearing properly lubricated.
the engine side u-joint grease fittings are real
fun to get to:rolleyes: i havent figured out yet if
these can be lubed without removing the shafts,
i'll let you know this spring.
hope this helps:)

Those "shims" are custom ground for every application. Do not ever loose track of where the shim goes! I did and had to send the entire assembly back to Stellings for realignment!

Stellings forgot to shim one of the bearing carriers in one of my extension boxes they sent me. So one of my gimble bearings were going away on me. This may sound kinda funny, but you have to make sure the gimble bearing is fully greese with a zerts gun first before you can feel the damaged bearing. Simply feeling/spinning it with your fingers won't let you feel how bad it is until you make sure it's fully greesed otherwise the bearing will seem like it's actually okay when it's actually LYING to you.
