Dear all,
Could one of you share the steps / procedure to replace the 2 belts of the Leece and Neville alternator (SM2K comfort pack/Yanmar 4JH3 HTE).
This would be of great help!
Thanks in advance!

There are 2 bolts on the lower side (bottom) to loosen to remove the belts.

There is one bolt on top:

When all 3 are loose, swing the Leece Neville Alternator to starboard enough to remove the belts.

Place the new belts on the pulleys

Use a tool like this to tighten the belts so that there is no more than 15mm movement when you press in the middle of the belts

When the belts are tightened to the correct tension, tighten the bolts

In addition to Bill’s comments , you should also buy the belts as a matched pair.

They are available in that configuration.
The belts will then be equally tight.
