PTO Adaptor Series 00.18.07 \u2014 Full Model Matrix<\/h3>\n

The 00.18.07 series provides an alternative body length and coupling geometry. It shares identical spline profiles with the 00.18.02 range but features different overall lengths \u2014 notably 165 mm on select metric conversions \u2014 suited to applications where driveline clearance demands a slightly longer barrel.<\/p>\n

\u2b50 Key Features & Advantages of Our PTO Shaft Adaptors<\/h2>\n

Designed for demanding agricultural and industrial environments, every adaptor in our catalogue reflects a commitment to durability, precision, and interchangeability. Here are the core reasons farmers and equipment dealers trust our PTO conversion adaptors.<\/p>\n

\n
\n

\u2699\ufe0f<\/p>\n

CNC-Machined Precision Splines<\/h4>\n

Every tooth profile is cut on multi-axis CNC hobbing machines to tolerances within \u00b10.02 mm, ensuring zero backlash and smooth power engagement from the first installation.<\/p>\n<\/div>\n

\n

\ud83d\udcaa<\/p>\n

Case-Hardened Alloy Steel Construction<\/h4>\n

Manufactured from 20CrMnTi alloy steel, carburised to a surface hardness of HRC 58\u201362 while retaining a tough, shock-absorbing core for extended fatigue life under cyclical torque loads.<\/p>\n<\/div>\n

\n

\ud83d\udd04<\/p>\n

Universal Cross-Compatibility<\/h4>\n

Over 50 female-to-male spline combinations span every mainstream agricultural standard \u2014 ASAE S203, ISO 500, DIN 9611 \u2014 so one supplier covers your entire fleet.<\/p>\n<\/div>\n

\n

\ud83d\udee1\ufe0f<\/p>\n

Anti-Corrosion Surface Treatment<\/h4>\n

A phosphate coating combined with a rust-inhibiting oil film protects adaptors during outdoor storage and transit, maintaining dimensional integrity in humid or coastal climates.<\/p>\n<\/div>\n

\n

\u26a1<\/p>\n

Drop-In Replacement Design<\/h4>\n

Pin-hole alignment and overall lengths match OEM specifications for direct replacement of worn or damaged adaptors \u2014 no shaft modifications, no rebalancing required.<\/p>\n<\/div>\n

\n

\ud83d\udcc8<\/p>\n

Cost-Effective Fleet Standardisation<\/h4>\n

Instead of purchasing dedicated PTO shafts for each implement, a single adaptor lets you run mixed-standard equipment on one tractor \u2014 cutting inventory costs by up to 40 %.<\/p>\n<\/div>\n

\n

\ud83d\udce6<\/p>\n

Compact & Lightweight Barrel<\/h4>\n

With body lengths between 140 mm and 175 mm and minimal added weight, these adaptors preserve driveline balance and do not compromise safety shield clearance.<\/p>\n<\/div>\n

\n

\ud83d\udd0d<\/p>\n

Laser-Etched Part Numbers<\/h4>\n

Permanent laser marking on each adaptor barrel makes field identification instant, simplifying reorder and warranty claims even after years of service.<\/p>\n<\/div>\n<\/div>\n

\ud83d\udee0\ufe0f Installation & Usage Guide for PTO Spline Adaptors<\/h2>\n

Step-by-Step Installation<\/h3>\n
    \n
  1. Identify both spline profiles<\/strong> \u2014 Measure the tractor PTO stub (female end of the adaptor) and the implement input shaft (male end). Count the number of teeth and measure the major diameter to confirm the profile code (A through N).<\/li>\n
  2. Select the correct adaptor part number<\/strong> \u2014 Cross-reference the female and male profiles against the 00.18.02 or 00.18.07 model tables above.<\/li>\n
  3. Clean all mating surfaces<\/strong> \u2014 Remove old grease, dirt, and surface rust from both the PTO stub and the implement input shaft with a wire brush and solvent.<\/li>\n
  4. Apply fresh grease<\/strong> \u2014 Coat the female bore and male splines of the adaptor with a lithium-complex EP2 grease to reduce insertion force and minimise wear.<\/li>\n
  5. Slide the adaptor onto the tractor PTO stub<\/strong> \u2014 Rotate gently until the splines fully engage. Confirm the retaining pin or snap ring seats in its groove.<\/li>\n
  6. Connect the PTO driveline shaft<\/strong> \u2014 Slide the implement’s yoke or tube onto the adaptor’s male end, securing it with the appropriate locking collar or shear pin.<\/li>\n
  7. Reinstall the safety shield<\/strong> \u2014 Ensure the PTO guard covers the full length of the rotating adaptor and driveline. Never operate without a shield in place.<\/li>\n
  8. Test at low RPM<\/strong> \u2014 Engage the PTO at idle speed first, check for vibration or unusual noise, then gradually increase to operating RPM.<\/li>\n<\/ol>\n
