We all know that the Continental Z120 series of gasoline engines used in the Ferguson T0-20 were prone to cracking. The indication is that the engine was under designed to be a load bearing structural member. Ferguson started 1945 UK TE-20 production with US built Continental Z120s and then switched to the Standard built engines when they became available.
Standard Motor Company designed a gasoline engine based on the Continental Z120 to be used in the TE-20 but they beefed up the design so their engine did not crack. This is discussed in the “The Book of THE STANDARD MOTOR COMPANY”. My as yet unverified suspicion is that Standard Motor did not closely share with the Ferguson organization the improvements they had made with their engine so Standard’s would remain the preferred engine.
The Ferguson TO-20 started out largely as a copy of the TE-20. Ferguson started 1948 TO-20 production in Detroit with the Continental Z120 and then went to the Z129 for the TO-30 without ever having Continental fully correct the design flaw.
Looks like it would be possible to machine an engine block out of a solid chunk of steel to replace a cracked Continental Z120/Z129 casting. The key might be reverse engineering a Continental block to get a set of accurate drawings that could be used for the machining.
Cost effective? No.
