1936 Pierce Model 1601

Jerry,

My “Motors” manual says it is positive earth (ground). There was a thread on “Turnpike Cruiser, that covered the piston options. Put Turnpike cruiser in the search field.

I used Egge pistons a long time ago in my ’33, and they work fine if you allow about 0.003″ clearance. (We first had 0.0015 – 0.002″ clearance, and they seized).

In my ’34 I recently used Arias pistons with one less ring groove and shorter skirts – less friction. A little better quality than Egge, in my opinion.

Bob, out of curiosity, did the Egge pistons have steel inserts for strength like the originals, or were they the replacement style that included lots of extra material around the wrist pin boss to add strength?

John

I think the steel inserts are called Invar struts. Egge won’t use that term (I think Chrysler owns the name), but when I asked someone there said that they had them. I would call and ask.
