Covers exact zerk locations (including the tricky under-seat hydrostatic linkage fittings), a firm warning against over-greasing the front axle pivots, and loader subframe bolt torque in foot-pounds. Best for new T474 owners building a maintenance routine.
An owner-operator channel run by a retired fire captain who uses the T474 on his own property and shares practical maintenance guidance from personal experience.
There are three grease fittings on the hydrostatic linkage under the seat, plus one more on the crossover brake shaft end nearby.
Only a pump and a half to two pumps max. Forcing more can blow a seal or damage the O-ring on the dry front axle seal.
The front loader subframe mount bolts use a 22mm socket and should be torqued to about 90 to 100 foot-pounds.
No. Do not mess with the preload set bolt unless highly trained, since it can ruin the front differential gears if set wrong.
