Would a input shaft bearing be covered by warranty after a 2 month old refurbished Gearbox?

As title above states. Its for a Honda Civic 1.4 2002

While most refurb items come with a warranty. It will depend on exclusions eg any work limited to replacing component in gearbox only and costs such as removing box etc will not always be covered.
Even so there's an expectation of things being fit for purpose in law. At this short use unless exceptional mileage? Or abuse? It ought to last longer.
Refer to supplier for response. Ought to offer to replace or repair box.

IT depends on the warranty. Some are only 30 days, some 60 some 90 some 6 months and some 1year.

Hi if a bearing is damaged after just two months something has caused this. Usually the front bearing in the flywheel is missing.
hence the lateral wear.
