Organic Clutch Disc 14 in

Organic facing on a fourteen-inch disc

Sachs builds this sprung-hub organic clutch disc for Class 8 manual and automated-manual transmission work where smooth engagement matters more than aggressive bite. Organic facings trade some heat capacity for quieter takeoffs and less chatter when drivers creep in yard traffic. The fourteen-inch diameter listed on the card is the sizing cue shops use when the flywheel housing is already open and the old disc is on the bench.

Linehaul fleets running Detroit-family and Paccar-family engines in Freightliner, Kenworth, and Peterbilt cabs often standardize on one disc spec across several model years so PM stock does not multiply. This listing targets those combinations where the fitment table shows DD15 and X15 rows on Cascadia, MX-13 and X15 on 579 and T680, spanning the years published above the prose block.

Price on the card is $289.00 USD before tax. Published ship weight is 18.0 lb, which usually moves as ground parcel but still deserves a two-person lift when you are aligning splines at chest height. Tax, if applicable, follows your ship-to state before dispatch.

When the transmission tells you first

Drivers describe clutch wear as a high pedal, shudder on engagement, or a burned odor after a long grade. Those symptoms overlap with contaminated facings, weak release bearing travel, or oil on the disc from a rear main leak. Before you order, inspect free play at the release fork or external adjuster per the transmission maker procedure, and look for facing glaze or rivet height on the removed disc.

Automated-manual units still rely on a friction disc that must center on the input shaft splines. Skipping the alignment tool invites pilot bearing noise and uneven wear on the next facing. Treat clutch work as downtime you schedule, not a roadside gamble.

• Photograph the flywheel step and dowel pattern before the disc leaves the truck.
• Compare spline count and hub standoff to the core you removed.
• Verify release bearing contact pattern while the housing is apart.
• Log engine and transmission tags on the work order for later crews.

Engines named in the fitment table

Published rows tie this disc to Freightliner Cascadia with DD15 or X15, Peterbilt 579 with MX-13 or X15, and Kenworth T680 with MX-13 or X15 across the model years shown in the table. Those pairings are shopping shorthand for common over-the-road specs, not a certificate that every VIN in your terminal will match without inspection.

Verify using the stamp on the removed disc, transmission identification, and VIN build data when you have access. Repowers, clutch kit swaps, and vocational spec changes can leave a familiar badge on a truck with different spline geometry. We describe compatibility; we do not promise a match from model names alone.

Email stamp photos and VIN to support@aonetruckauto.com when the old disc is gone. The contact form preserves a paper trail for fleet POs. Use the fitment guide when you are comparing several clutch listings across sister units.

Bench handling for heavy friction

Eighteen pounds of steel and friction is awkward on a transmission jack. Keep hub faces off concrete and away from oil-soaked rags. Organic facings pick up grit that becomes chatter after install.

When the purchase order cites Sachs 33050, compare the embossing on the old disc before you break the seal on the carton. Shelf fulfillment uses SKU SAC-33050 on cart and PayPal lines at the unit price shown on this page.

Support the transmission per OEM procedure when the bell housing is open. Dry-fit the disc on the input shaft by hand to confirm spline engagement before you torque pressure plate hardware to the published pattern in the service manual for that transmission family.

After assembly checks

Set clutch free play to the transmission chart, not to habit from a different fleet unit. Cycle the release mechanism and confirm the disc centers without binding. Road test with light load before you dispatch on a long grade if the facing is new and burnish is required.

Do not invent break-in mileage numbers here. Follow the clutch and transmission guidance packaged with the OEM kit for your VIN.

Receiving and returns

Inspect the carton when it hits the dock. Friction faces crushed in shipping belong on a freight claim before install. Store discs flat on a clean shelf away from aerosol overspray.

Unused returns follow the window on returns and refunds. Installed clutch components may fall outside return eligibility once the facing touches a flywheel; read that policy before speculative stocking.

Carrier options and packaging notes are on the shipping policy. Transit depends on the service level you approve at checkout.

Fleet stocking angle

Regional managers sometimes keep one disc per common engine lane and a second on the mobile unit for the rare week when two tractors pick up clutch chatter in the same terminal. Document which stamp was installed so purchasing does not reorder from memory after a driver swap.

PayPal totals multiply the card price by quantity; capture success displays only after payment completes. That confirmation is not a fit approval—technicians still confirm on the truck.

Packaging and carrier options are described on the shipping policy. Return eligibility is on returns and refunds. Questions: support@aonetruckauto.com.
