Разница как между моторами ГАЗ и УАЗ. 70% запчастей взаимозаменяемы.

Some folks like that feature, others view it as a drawback. I personally prefer a bit more [/color]displacement[color=rgb(0,0,0);font-family:verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif;font-size:13.333333015441895px;] and lower engine speeds, and am pretty happy with my Kubota based Nanni 43 hp.

Yanmar owners correct me if I'm wrong here...[/color]

These are pricey and IMO should last a hell of a lot longer than what Yanmar figures! The one on my engine has over 4000 hours usage and seems fine.[/color]
Подшипники и сальники у них, конечно, стандартные, думаю, такие же как у ГАЗ и УАЗ.
