Replacing drive chain on gearbox sprocket on assembled engine

I was a bit on my toes after removing the drive chain completely while doing a major brake overhaul on my T140D.
Now the chain is back on the bike. If I had luck or not I don't know, but I didn't find it difficult to do.

With the chaincase and left sidecover removed:
  • Stuck a small bit of wood under the rear wheel so it wouldn't rotate
  • Smeared some grease on 15-20cm of the feed end of the chain
  • Laid the chain over the rear sprocket so I could feed it a few links at a time towards the front sprocket
  • With my fingers (I don't have piano fingers!) I reached in and fed the chain slowly onto front sprocket, while giving slack over the rear sprocket.
  • The chain would "glue" itself to the front sprocket, so I could see it coming around to the underside
  • Used a bit of string (see post #3) to catch the chain and move it further
  • Put the connecting link on after having both ends resting on the rear sprocket

I may have had a bit of luck, and in my basement it was only 8 to 10 centigrades, so the chain wasn't too loose.

Helge.
