Johnson ADL-10

I stumbled upon this little motor the other day. I believe it was a long shaft originally but somewhere along its life it has been converted to a short shaft.
It hasn’t run for a great many years but apart from that it seems well cared for. Compression (bone dry) is 79.6 (T) and 79.4 (B). I’m hoping the numbers to come up a bit once it is running again. It still has a strong spark although the coils are badly cracked. Both coils still seem original. Other than that it seems complete and just in need of a general service (ignition, impeller, seals and carb).

I’ve torn it apart for painting but I cannot get the shaft in the lower unit to come out (the shock absorber?). Is it just a matter of pulling the gear off, or is this gear fixed to the shaft somehow?

The pinion gear is a snug fit on the shaft so the shaft must be driven out of the pinion using a large punch. If all goes well, the small Woodruff key will stay in the shaft.

Turns out it needed just a very gentle tap to come off.

Those compression readings are normal for this low compression engine…

nice coils… should be a nice runner when all fixed up.

 

on my last 5.5  shock absorber I had a heck of  a time resealing the GC and  getting the drive shaft to turn … the shock absorber was stretched and I simply  knocked it back to 6 inch 11/16

then I had it spot welded shut and installed a  brass dive pin.

been reading lots of old posts  on shock absorber  size…. 6″11/16  seems the magic number … mine meaures  6″ 13/16 .

while initially  working the housing  I recall it falling out  on the  ciment floor  and wonder if it got  messed up then ???   anyhow… pursuing the adventure

GC gears turn fine on their own  but driveshaft turns about 3/4 turn and binds… on its own   . I’ll reinspect the  shock absorber  and  if  6″11/16 is the magic  number I’ll have my neighbour  tack weld it  at 6″11/16.

Thanks crosbyman.
Blasted it today and got the primer on.
Tomorrow it’s time for spraying color.🙂

I’m hoping it’ll be a good runner. It seems well cared for, no broken bolts this time
