On rare occasion the water tube may require replacement. In that event deflare the tube and
draw it out the bottom of midsection. Use the old tube as a pattern to bend replacement tube
Allow a bit extra length at both ends of replacement tube. Installing tube in exhaust housing
requires a bit of wiggling. Once in place cut to length and flare upper end. Make sure tube
does not interfere with drive shaft. Lower end of tube can then be adjusted for length.
I have done this on WD4 and it should be about same on KE4 with exception of the rubber
adapter into gear case.
Not often needed but not a big deal. Helps to lay old tube on board and tack a pattern
of wood on board to form a channel to mold new tube into.
