If no kit available, which parts should I include if I were to buy separately?
Referencing the picture above, I’m thinking #’s 11, 12 (*), 15, 16, 32, 44, 45, 46 and 53.
* if needed
Does that look complete?
And what engine to reference? I had to buy TN-28 Ignition parts. Can I source these for the model 5D10G or the TN-28 or other?
Use the part numbers from the 5D10 parts list posted above. Many of them will be superseded by current numbers, but hopefully your dealer will know that.
BTW, 99.9% of the gearcase parts are identical between the 5D10 and TN-xx and have the same part numbers.
If the end of the clutch cable is not frayed, you can pull the lower unit down to make it easier to access the water pump and the clutch cable should easily push back up through the hole.
