Cat engine model year

Call a CAT dealer.

 

I think you good for paper logs.

 

12 of 99 build is gonna be meets 2000 emissions standards.

2WS prefix is what your searching for. Though there are just a very few 6nz 99 emissions standard engines

 

I may be wrong but I thought it was all about the engine model year. Like when the engine was built.. nothing to do with emissions. If engine was built 99 and prior your fine..

 

Like @wore out said, they are going on the emissions year standards in the latest ruling.

It could be a 99 build date, but if it qualified in the the 2000+ emissions specs, then your outta luck on the exemption.

My 2ws is a 11/99 build date. The sticker says meets 99 emission standards. It's in a 2000 w900
