Overview
Product Description
S38 is to S8 what T7N is to T7 — the same torque class and cross-kit dimensions (35×94 mm), but a different tube outer diameter for implement housings that cannot accept the standard tube OD. S38 and S8 are not interchangeable at the implement housing despite sharing the same cross-kit specifications. Always confirm whether the implement manual specifies S8 or S38 before ordering — the part numbers look similar but the tube profiles are mechanically distinct.
For distributors and service workshops, S38 and S8 cross kits are interchangeable — the same 35×94 mm cross kit (code 8.01) fits both shaft series. This simplifies cross-kit inventory: stocking one part number covers both S8 and S38 cross-kit replacements. The tube and yoke assemblies are not interchangeable — these are ordered by series.
S38 is less commonly stocked than S8 due to its narrower OEM specification. Standard stock availability is 7–14 days; confirmation of stock is recommended before committing to a delivery schedule. For OEM contracts, contact Ever-Power Drive Line to establish a blanket order arrangement.

Key Features
Star Tube Profile — Six-Lobe Bore
The star (six-lobe) tube cross-section provides the highest torsional rigidity per unit outer diameter of any standard agricultural PTO tube profile. Specified by European implement OEMs for input housings machined to star bore dimensions — incompatible with triangular or lemon tube profiles.
Sealed Cross-Kit Bearings — IP67
Double-lip sealed needle-roller bearing cups, factory-filled with EP2 lithium complex grease. Grease nipple accessible with shield in place. Rated for 350+ hours between maintenance interventions in standard field conditions.
CE Safety Shield — Standard
CE-marked UV-stabilised HDPE bellows guard matched to S Series tube outer diameter. Spring-clip anchors and chain points at both ends. OECD Code 4 compliant. Included as standard with every S Series unit.
Forged 20CrMnTi Steel Yokes
Drop-forged chromium-manganese-titanium alloy steel yokes, normalised and induction-hardened at bearing seat journals. Designed for sustained peak torque applications in large baler and forage harvester duty cycles.
All Spline Standards Available
1-3/8 inch Z6 (540 rpm), 1-3/4 inch Z20 (1,000 rpm), and 1-3/8 inch Z21 push-pin or bolt-clamp yokes. Both ends specified independently at order.
CE + ISO Certification Package
CE Declaration of Conformity, ISO 9001:2015, TS/16949 process certificate, LGPD compliance documentation. SGS third-party batch inspection available on contract orders.
Typical Applications
S Series star tube — 60–90 hp tractor class applications
Square Baler Feeder — Narrow Housing
S38 delivers S8-equivalent torque (1,050 Nm) in a narrower star tube outer diameter for square baler housings that cannot accommodate the standard S8 tube OD. Specified by European OEMs for their medium-size square baler range.
Heavy-Duty Rotary Tillers — Star Bore
Large rotary tillers on 65–90 hp tractors where the implement input housing specifies S38 star tube over standard S8. The narrower S38 tube profile allows the shaft to clear implement frame elements that the S8 tube contacts.
Forage Harvester Intermediate Drive
Intermediate shaft position in multi-shaft forage harvester configurations where a star tube is required and the tube clearance at the frame is tighter than S8 standard allows.
Installation and Maintenance
Attach safety chain to a fixed non-rotating point on both tractor and implement
Confirm Torque Class
Calculate implement demand (Nm). Add 20% safety margin. Select the lowest S Series where Nm@540 (or Nm@1000) exceeds the adjusted figure.
Adjust Working Length
Measure coupling centre distance with implement attached. Verify 50 mm min tube overlap at full extension, 80 mm at full compression.
Engage Yoke Connections
Push-pin yoke: engage at PTO stub and confirm audible click and positive retention. Clamp yoke: torque to manufacturer specification.
Anchor Safety Chains
Connect tractor-side chain to guard or frame; implement-side chain to implement body. Verify taut at working height.
Grease Before First Use
Apply EP2 lithium complex NLGI 2 grease (2–3 pumps) to both cross-kit nipples. Service every 8 hours; 4 hours in wet or abrasive conditions.
Frequently Asked Questions
- —S38 and S8 share the same 35×94 mm cross kit and identical torque ratings (1,050 Nm at 540 rpm)
- —Tube outer diameter differs: S38 uses a narrower star tube profile for tighter implement housings
- —Cross kits are interchangeable; tube and yoke assemblies are not
- —Always specify implement model when ordering to confirm S38 vs S8 requirement
- —S38 is a lower-volume series — confirm stock availability before committing to a delivery date
