The
Clutch Disc VALEO 41300V7150 is a total workhorse for manual-transmission JAC T8 pickup trucks—it’s the key "power linker" between the engine and
gearbox, responsible for smoothly passing engine power to the transmission (and ultimately the wheels) when you let off the clutch, and cutting that power when you press the clutch to shift gears. Made by VALEO (a top-tier auto parts brand), this isn’t some generic part—it’s tailor-made for 2018–present JAC T8 models with manual transmissions, covering both 2.0T diesel (like the 4DB2-1D1 engine) and 2.0T gasoline (4GA3-3D/4D) variants (Comfort, Elite, Luxury trims).
Without a working clutch disc, your T8’s manual gearbox is useless: press the clutch, and it won’t disengage (so you can’t shift); let it off, and it might slip (power goes nowhere, or the engine revs but the truck doesn’t speed up). Below’s a no-jargon breakdown of what this VALEO clutch disc does, how it works, and why it’s a must for your T8’s manual setup:
This clutch disc has three non-negotiable jobs that make manual driving smooth and reliable—here’s how it impacts your daily use (especially for heavy hauling, which T8 pickups are built for):
Smooth Power Transfer: When you release the clutch pedal, the disc’s friction surfaces press tight against the engine’s flywheel and the clutch pressure plate. This "locks" the engine to the transmission, sending power to the wheels without jolting. For example, when you start from a stop (or haul a load in the truck bed), it keeps the engine from stalling by gradually letting power flow—no jerky starts.
Disengage for Shifting: When you press the clutch, the disc pulls away from the flywheel/pressure plate, cutting the power link. This lets you switch gears (from 1st to 2nd, for example) without grinding the gearbox—something that’d ruin your transmission fast if the disc didn’t disengage cleanly.
Buffer Engine Vibration: Inside the disc, there are small 减震 springs (damper springs) that soak up vibrations from the engine. This stops those rough, "shaky" feelings from reaching the gearbox and steering wheel—especially when you’re idling in neutral or cruising at low speeds. It also protects the gearbox from wear caused by constant vibration.
Handle Heavy Loads: VALEO built this disc for the T8’s hauling needs—it can handle up to 300Nm of torque (perfect for the 2.0T diesel’s max 320Nm). Hauling a full bed of cargo? The disc’s tough friction material won’t slip, even when you accelerate hard with a load.

This VALEO 41300V7150 clutch disc only works with JAC T8s that have a manual transmission—it won’t work on automatics or other truck models. Here’s exactly what it fits (and what it doesn’t):
Target Models: 2018–current JAC T8s with 5-speed or 6-speed manual gearboxes. It covers every trim level—Comfort, Elite, Luxury—and works for both the 2.0T diesel (4DB2-1D1) and 2.0T gasoline (4GA3-3D/4D) engines.
What It Won’t Fit: JAC T8s with automatic transmissions (those use torque converters instead of clutch discs), JAC T6 pickups (they have different flywheel and transmission sizes), or non-JAC trucks (such as the Great Wall Wingle).
What It Needs to Pair With: It has to be matched with the JAC T8’s original VALEO clutch pressure plate (look for part numbers in the 41300V71xx series) and clutch release bearing. If you mix it with aftermarket pressure plates, you’ll get clutch slippage or uneven wear—VALEO designs these parts as a “set” to work perfectly together.
Trying to install this clutch disc yourself is just asking for trouble—only JAC-approved technicians (or VALEO-certified repair shops) should handle this. Here’s why:
Alignment Is Make-or-Break: The disc has a tiny “locating pin” that has to line up exactly with the flywheel’s guide hole. Even a 2mm misalignment will make the disc rub, which wears it out fast and causes gear grinding. Techs use JAC’s special alignment tool to get this spot-on—no guesswork.
Torque Has to Be Perfect: The pressure plate bolts (these hold the disc to the flywheel) need to be tightened to 25–30 N·m, and you have to do it in a “crisscross” pattern. If they’re too loose, the disc slips; too tight, and you’ll crack the flywheel. Techs use torque wrenches for this, so there’s no risk of over- or under-tightening.
The Clutch Pedal Needs Adjusting: After installation, the pedal’s “free play”—that’s the small amount of movement before it starts to engage—has to be set to 15–20mm. Too much free play, and the disc won’t disengage properly (you can’t shift smoothly); too little, and it stays partially engaged, which makes it overheat.

Summary
VALEO’s 41300V7150 is made to handle the JAC T8’s tough daily use—whether you’re hauling loads, going off-roading, or just driving around on regular days. This isn’t just any old part; it’s peace of mind knowing your manual T8 will shift smoothly and hold up well over time.
Bottom line, the VALEO 41300V7150 Clutch Disc is the total "heart" of your JAC T8’s manual transmission. Without it, you can’t shift gears, can’t haul anything, and you can’t even drive. Stick with this original VALEO part, have professionals install it (along with the matching pressure plate and release bearing), and your T8’s manual gearbox will keep chugging along strong for years.
