Re: Johnson CD & RD Crank taper question

[RICHARD A. WHITE]

From my limited experience of making the timing tools, most key ways are parallel to the taper, except for the 1962 and up with the large taper.

For example:

28 hp thru 40 hp 1962 and up

1962-1973 28,33,40 ho motors
And the following 35 hp 1976 and 40 hp 1974 thru 1976

The above mentioned the key is parallel with the crank centerline

The others:

22hp thru 40 hp thru 1961 with small crank shaft (including Gale 25 hp thru 1963)

1951-1961 22, 25, 30, 35, 40 hp motors

ALL YEARS 22-25 hp Gale motors

3 hp and 4 hp

1952-1976 3 and 4 hp motors

1981-1986 4 hp motors
5 hp thru 20 hp (including the 22 cubic inch 25 hp)

1951-1976 5, 5.5 and 6 hp motors

1951-1958 7.5 hp motors

1964-1973 9.5 hp motors

1951-1963 10 hp motors

1951 and up 12 hp Gale motors

1951 14 hp motor

1951-1972 15, 18, 20, 25 hp motors

1973-1976 18, 20, 25 hp motors

The key is parallel with the taper..

I have been wring before, but pretty confident on this one.

Richard
