There might be unique casting numbers if tractor versions have a different, more rigid block (we call 'case' in the factory) than 'industrial', tho' I suspect otherwise.
If the same block is used for tractor and industrial the difference may be in whether the balance shaft bores are 'finished'.
'Service' blocks (factory spares) might then have those bores finished to be supplied for either final assembly line or customer preference. The parts might then be added before installation. This is high-hoping, of course, but we'd want to be certain.
Is there a cover or easily removed part that would expose an existing drive gear etc that would make the shafts more easily apparent? In some auto engines a drive gear can be seen when camshaft gears are inspected/replaced. (we added balance shafts to Buick's 3800 back in the '80s)
If the model ID numbers we're given don't provide enough info, we'd have to rely on a seller's knowledge of 'whether or not' the shafts were included.
