Wade,
My eshaft was extra ornery to get off. I hope this
isn't going to be a big problem for you. Tried several hydraulic and hammering
devices. What finally worked was renting Bruce Turpentine's eshaft puller.
With several hours of attempting to remove it, Bruce's did it in less than 5
minutes. As usual the right tool for the job.
Way to go Mark.

Wade,
The 20B has a 2-piece eccentric shaft that must be
split to disassemble the engine. You should remove the #1 rotor, rotor
housing and front shaft, then #3, and finally #2. There is a threaded
hole in the rotor journal of the front shaft that you can thread an all-thread
into. I first tried a slide hammer approach, but that didn't work.
A good friend loaned me his home made adapter. It consists of an
all-thread, and a 1" thick plate with a hole that slips over the
all-thread. The 1" plate should be about 4" wide and 8 - 10" long, but
that's not critical, you just need the length for added leverage.
Using the plate and a large nut, you position the 1" plate down onto the
all-thread until it touches the end of the main shaft (extends through the
smaller shaft out the front of the engine). It should touch the e-shaft
about an inch or so from the all-thread. Screw the nut down to where it
is touching the 1" plate, and then go about a half a turn extra. One or
two blows with a medium sized hammer/mallet on the outer edge of the 1" plate
will pop the small shaft off the main shaft. Suggest you use a piece of
aluminum or brass between the 1" plate and the front of the e-shaft to prevent
damaging the threads. I was amazed at how well this simple puller
worked.
Note: the e-shaft should be supported from the flywheel end
when you smack the 1" puller plate with the hammer.
Hope this
helps,
Mark Steitle

Guys,
I'm in the process of pulling
the housings off of my 20B.
I have Bruce Turrentine's
video and I knew it would be a little different from a 13B.
I got the rear side housing, rear rotor housing and rotor off, but I
cant seem to find the way to get the next side housing off. I tried
the method as shown in the video. I've lifted the shaft but the housing but
it doesnt want to move toward the eshaft so I can rotoate it
off.
Anyone know the method for a
20B?
Thanks,
Wade
