Case 420 crawler engine

[Chris Klein]

What gas engine was used in the case 420 crawler? Does anyone have specs on this thing like horse power and weight ?

FWIW, a 94 Clevite catalog shows the "420 Series" crawler coming with the 148, the 188D and the A251 engines. The "420 Series" tractor, which I assume means wheeled, had the same.
These parts catalogs don't specify whether they were engine options or serial replacements.
That catalog has separate listings for an array of 420B's and 420C's; I don't follow Case, so I don't know what-all is included in "420 Series".
Case has their own engine designations: that catalog shows the 188 coming as: G188, G188B, G188D, 188, 188B, 188D, and 188S, with the others having some similar variations.
148's=3.375x4.125
188's=3.813x4.125
251's=4x5
By coincidence, someone in Australia was looking for info on a 420C crawler last week or so on Tomm.com.au
