tappet

2018 Dec 28 - Legare Tappet

CSM: This is the underside view of the component that rests on the ribber dial. Fascinating

I had been having infrequent issues with ribber needles jamming and beheading themselves on the tappet plate. When I was able to compare my ribber tappet to two others I found an interesting difference in the design (EVEN THOUGH they were all made for the same model Legare). My Tappet as it turns out - appears to have had way more wear than my machine was used - so with Susan Forsyth’s help we determined at some past point this Tappet was introduced to this machine (my ribber alignment/timing issues were not because of the timing!)

After viewing the slight other versions of the same part I determined my Tappet just needed a slight adjustment of the ‘shelf’ where there was slightly not enough room for the workings of the ribber needles.

With my dremel and polishers, I very slightly thinned the slightly thicker ledge, created a tighter curve on the dial needle damage area (allowing clearance) then smoothed prior damage. It worked like a charm!

Thanks to Susan Forsyth for the work-through Jan 19/19 and comparison parts that were essential in determining the tappet to be the issue.

The Ribber image shown above is the whole unit. It consists of the Ribber Arm, the L shaped drive pin, the timing screw, the Ribber Dial Post to which the ribber dial and Tapper and hung on, securing the post by a screw at the top of the ribber arm.
