    Item was new and fit in my SCAG STC48V-23CV but it did not solve left side hydro-gear surging when going backwards. I replaced this along with the upper swash plate, replaced oil with filter and still get surging when moving lever backwards. Might be the wheel motor or the hydro-gear, but i'll live with it for now and replace it once it goes bad completely.

    quality oem unit

    Installed with the 21cc kit, a new center unit, and 20w-50 synthetic motor oil on an old Dixon. Brought my mower back to life.

    Hydro gear block kit

    Exactly what my pump needed , completely restored it back to “like new” pump pressure. Easy to install, saved $600 over purchasing a new pump .
