1929 one year only push rod parts.

[pete reeves]

Anybody on this forum know what a Push rod felt washer retainer cup.a Felt washer and a retainer cup spring look like? According to the parts book they are 0ne year only parts fitted to 1929 Js both 61 and 74inch. although they are listed in the 1927 to 1931 parts book there is no picture
I am assuming that they may have something to do with lubricating the top ball on the push rod. But I have nether seen them so that's only my guess.
The part numbers are 133-29 134-29 135/29
