Repair Instructions P46HT | Giant specification

REPAIR INSTRUCTIONS - P46HT

1.To Check Suction and Discharge Valves

Loosen valve plugs (41 and 43) using a socket wrench. Note the arrangement for reassembly and check the discharge valves underneath and suction valves (in suction valve adapter 39).

2.To Check V-Sleeves

Separate valve casing (29) from the crankcase (1) and pull off over the plungers. If the seals have to be replaced, remove all parts from the valve casing (29) in the suction valve direction. Grease new v-sleeves (31) with grease before installing. Examine the surfaces of the plunger pipes (24A) as damaged surfaces cause the seals to wear out quickly.

3.To Check Plungers and Crankcase

If oil leaks at plunger outlet (22), and or the radial shaft seal (26), the worn plungers and crosshead (plunger assembly) must be placed. Drain oil and remove crank- case cover (3) and valve casing (29). Take off bearing cover (12) and shaft protec- tor (17) on one side before removing the crankshaft (18). Then remove crankshaft axially by means of a press or a rubber hammer. Do not force the cranks on the shaft when pulling through the connecting rod (20). Do not bend connecting rod. Dismantle crosshead and connecting rod and replace worn parts.

Reinstall the crankshaft first being particularly careful with the cranks. Then press on the bearing on both sides and finally install radial shaft seal and bearing cover.

4.To Replace Plunger Pipes

Screw out tension screw (24B), pull off plunger pipes (24A) and clean plunger surface. Install new plunger pipe. Fix tension screw with screw-glue and tighten carefully at 106 ft.-lbs.

5.Drip-Return

After the valve casing has been removed, the weep seals (50) in the intermediate casing (46) can be examined and replaced as necessary. Should lime deposits occur in the valve casing, care must be taken in keeping the two holes in the valve casing (29) free to ensure trouble-free drip-return.

The geometry is strategically designed to enhance stability during descents and improve agility while cornering, giving athletes the confidence to push their limits.

One of the standout features of the P46HT is its suspension technology. Equipped with a front suspension fork that boasts a significant travel distance, it effectively absorbs shocks from uneven surfaces, ensuring a smoother ride. This capability ultimately contributes to better traction and control, particularly on technical trails. The rear of the bike features a robust design that allows for efficient power transfer, enhancing overall ride efficiency.

The P46HT also incorporates cutting-edge tire technology. Its wide tires provide exceptional grip and traction, enabling riders to maintain control on loose gravel, mud, and rocky terrains. These tires, combined with the bike's well-engineered clearance, reduce the risk of mud accumulation, enhancing performance in wet conditions.

The drivetrain on the Giant P46HT is engineered for seamless shifting, utilizing a high-quality groupset that ensures smooth transitions between gears. This feature allows for quick adjustments in response to varying terrain, making it easier to maintain optimal cadence and speed.

Another highlight of the P46HT is its braking system. Featuring hydraulic disc brakes, this bike guarantees powerful stopping performance in all weather conditions. Riders can rely on consistent and precise braking, which is crucial for navigating steep descents or tricky corners.

Further enhancing the riding experience is the bike's ergonomic design. Components such as the saddle and handlebars are designed to provide maximum comfort, reducing fatigue during long rides.

In summary, the Giant P46HT stands out due to its combination of innovative technologies, robust construction, and rider-focused design features. Whether conquering steep hills or cruising through scenic trails, the P46HT is engineered to deliver an unparalleled mountain biking experience.
