Thank-you Louis. I appreciate your response and the confidence to proceed with your information. Best regards.

Re: WF-4 propeller gear and shaft

Until you get the hang of it pressing gear on shaft to line up hole in gear with hole in shaft so 3/16" pin can be driven in is a cut and try. The use of
a 6" machinist's scale to eye ball alignment may seem a stretch but once you
develop the knack it works pretty well. As gear is pressed it is possible to
rotate gear/shaft into closer alignment using punches in holes to leverage
while pumping a stroke or partial stroke. Hydraulic pressure can be very gently applied and released to get holes aligned...may take some practice or you can get lucky. Using the straight edge of scale to align the holes is
the key skill...if you start it right all you need do is stop at right spot.
Mid course correction is an acquired skill.

Re: WF-4 propeller gear and shaft

Working on KB3 prop shaft today...after driving out retaining pin for gear
and water pump eccentric both were slip fit on prop shaft. Apparently between
corrosion and polishing the few thousanths of interference fit disappeared.'
Happens with really old motors that have been apart once or twice in past.

How did your "press on" work out?

I have seen a 1/2 bolt used as prop shaft replacement...not very successfully
A good try though.

Re: WF-4 propeller gear and shaft

I have not proceeded yet. Perhaps tomorrow evening I will give it a try. I am glad you added about lining up the holes. Trying to get the best alignment with the rule at the start will be a good idea. Thanks much.

Re: WF-4 propeller gear and shaft

The gear is now installed on the propeller shaft. I was able to make some adjustment as the gear was nearing the hole alignment. The pin is in, and all seems good. The water pump is assembled and needs installed back on the lower unit. Thank-you for all the help.
