Reply To: Caille Neptune gear case disassembly

[PM T2]

For lower units like yours, I recommend getting a tool made that will do the job. I machine a piece of brass that threads into the nose of the gear housing, then I drill & tap that piece all the way thru to accept a 1/2″ bolt. This gives you a removal tool that pushes on the front end of the propshaft without beating on it. You use the bolt to push the prop shaft out the back, since its a lot less distance for the shaft to travel instead of coming out the front. It might help to grind a slight point on the 1/2″ bolt to keep it centred on the end of the shaft.

Some Cailles do have the water pump eccentric as a separate piece from the gear, but they are keyed to the shaft instead of being pinned.

Hope it helps.

Best,
