This test is carried out to check engine power & transmission & hydraulic efficiency.
Place the transmission in 4th gear & hold the brakes – compare engine at full RPM in neutral & then compare under load by engaging Forward & then combining Forward & Hydraulic by crowding the loader bucket to full extent & holding against the stops.
TIP – while checking a Borg Warner shuttle transmission on a 580C,D,E or K compare FWD to REV – often Rev is still like new & will load better than a worn out FWD 😉
