Overview
Product Description
T8 uses a 35×106.5 mm cross kit, delivering 1,240 Nm at 540 rpm and 2,250 Nm peak. Despite using the same 35 mm pin diameter as T7N, the 106.5 mm journal length places T8 in a significantly higher torque class. T8 is the standard selection for 80–110 hp forage operations and large baler applications. For the full T Series PTO drive shaft range, see our category page.
T8 is widely used by OEM forage machinery manufacturers as the default drive specification for their 100 hp-class equipment. Ever-Power Drive Line has supplied T8 shafts on OEM custom-length basis to implement builders in Parana and Sao Paulo, with drawing approval and first-article inspection as standard process. The 2,250 Nm peak torque means T8 can handle transient forage slug loads without a torque limiter, although a friction limiter is recommended for high-density baling applications.
T8 and T7N use the same 35 mm pin diameter but are completely non-interchangeable at the cross-kit level due to the different journal lengths (106.5 mm vs 94 mm). This is a common source of ordering errors in the South American aftermarket. Always confirm the full cross-kit designation — 8.01 for T8, 7N.01 for T7N — before ordering replacements. Agricultural service workshops in the 80–110 hp tractor segment should have hydraulic press capability rated to at least 5 tonnes for T8 cross-kit replacement. Full CE, ISO 9001, and TS/16949 documentation for Brazil INMETRO and LGPD compliance. For technical enquiries, contact Ever-Power Drive Line.

Drop-forged from 20CrMnTi, heat-treated to HRC 28–32 at bearing seat. Designed for high peak-load applications without premature wear.
Sealed Cross-Kit Bearings
Sealed needle-roller cross kits, double-lip seal on each cup. Grease nipple accessible with shield fitted. No removal required to service.
CE Safety Shield Supplied Standard
CE-marked HDPE bellows guard supplied with every shaft. Yellow for field visibility. Spring-clip anchors and chain points both ends.
All PTO Spline Standards Covered
1-3/8 inch 6-spline (ISO 500), 1-3/4 inch 20-spline, and 1-3/8 inch 21-spline. Clamp yoke and push-pin locking both available.
Custom Length OEM Service
Manufactured to compressed and extended length per customer spec. DWG review before production. MOQ 50 pcs, lead time 25–30 days.
Full Certification and Traceability
CE, ISO 9001, TS/16949 certs. Batch records include dimensional check, torque sampling, and finish inspection. SGS on request.
Typical Applications
Forage Harvesters
Main drive for 80–110 hp PTO-driven forage harvesters. T8 rated for combined pickup, cutting drum, and blower loading at this horsepower class.
Large Round Balers
High-density large round baler on 90–110 hp tractors. Pair with friction torque limiter for slug protection during dense bale compression.
High-Flow Pump Stations
Industrial-scale irrigation pump drive at continuous 540 or 1,000 rpm. Suitable for turbine and piston pump stations on centre-pivot systems.
Installation and Maintenance
Attach safety chain to a fixed non-rotating point on both tractor and implement
Confirm Torque Rating
Cross-reference implement power with tractor PTO output in the table above. Select series rated 20% above maximum expected torque.
Adjust to Working Length
Cycle implement through full height range. Verify 50 mm min overlap at full extension, 80 mm at full compression.
Secure Yoke Connections
Engage push-pin yoke at tractor PTO; confirm audible click and positive retention. Bolt-clamp types: torque to manufacturer spec.
Route and Fix Safety Chains
Connect tractor-side chain to guard or frame; implement-side chain to implement body. Verify taut with implement level.
Grease Before First Use
Apply EP2 to both cross-kit nipples before initial operation. Service every 8 hours. Reduce to 4 hours in wet harvesting conditions.
Frequently Asked Questions
- —T7 and T7N share identical torque ratings but differ in tube outer diameter
- —T7N uses a narrower tube profile for specific European implement input housings where T7 creates interference
- —Always confirm T7 or T7N from the implement manual — cross kits are non-interchangeable
- —Connect the implement at normal working position and measure coupling centre distance
- —Compressed length must be 50 mm shorter than that distance; extended length 50 mm longer
- —Verify 50 mm minimum tube overlap at full extension and 80 mm at full compression
- —Drop-forged 20CrMnTi chromium-manganese-titanium alloy steel
- —Normalised, shot-blasted, and induction-hardened at the bearing seat journals after forging
- —Material certificates available per batch for import and quality documentation
- —T Series shafts are manufactured to balance tolerances for 540 rpm agricultural PTO operation
- —At 1,000 rpm, cross kits must be fitted correctly and in matched pairs
- —Custom-length shafts over 1,500 mm extended length are dynamically balanced before shipping
- —Electrostatic powder-coat in standard agricultural yellow or black
- —Yoke bearing seats and tube interior coated with rust-inhibiting oil before assembly
- —Salt-spray tested to 120 hours per ISO 9227 as part of outgoing quality inspection
