Destruction of pre-emissions engines?

A buddy was telling me yesterday that his Kubota parts man told him that they had to destroy any engine block from a pre-emussions tractor, then send in documentation to Kubota. The parts guy told my buddy to be careful buying certain years tractors because if he ever needs an engine block he will mot be able to buy new or used. Is there any truth to that? If so, why is it that way?
 
Well your answer is yes and no..First a dealer can order and get any engine block or complete engine. Warranty replacement engines (where the customer does not own the core) do have to have a hole drilled and photo sent to Kubota. Prevents the core from ending up in a rebuilders inventory.
 
I was looking at parts for my 743B bobcat (with the Kubota diesel), and if you want a new replacement engine, the part number for the replacement engine is for a newer tier2 emissions engine.
 
GM and Ford Do similar things with parts like headlight housings, tail lights, etc to keep the aftermarket from copying new crash parts. I've never seen an instance where an engine replaced under warranty didn't get called back for a post mortem...
 
Part of the problem with anything but the latest Tier 4B engines, is that there are only allowed to be X number out there. The fines for not complying are horrendously high. Like 35,000 a day or something crazy like that. Basically if you order a NEW, say, Tier 3 engine, the old one has to go back in something like 60 days, or you can get fined. Kubota may find it easier to have the dealer destroy the engine, and send proof, then to risk a shipping screw-up or the like. Like JM said, that would be on warranty engines only. Kubota can't destroy a customer owned block.
 
Thank the EPA for that.

Kawasaki engine division is similar. They will not sell replacements for their no longer currently EPA compliant engines unless the dealer signs off a document that the engine was destroyed. And the liability if caught is on the dealer.

So we take a sledge hammer to them to make sure the crankcase with that serial number on it can't be re-used.
 
GM dealer I worked at, we hardly ever had a warranty engine get called back by the PQC. They usually just went back as a normal core. Engines that GM only sold new, such as Northstars and the original Ecotec, just went in the scrap pile once the warranty claim cleared.
 
I have been using tractors for over 60 years and have never bought an engine block.
 
Why couldn't they just buy a new OEM part and reverse engineer it? Doesn't make sense to go bumming around a junk yard for an OEM design.

Exactly. That is how the Chinese do it.
