Description
Plain Bore Yoke Type F (Vertical Pin Hole) — Top-Access Pin Retention for Confined-Space Installations
ال Plain Bore Yoke Type F-Vertical Pin Hole was born from a practical observation: on many implements, the PTO input shaft sits deep inside a housing or frame, with structural members blocking horizontal access from the sides. Technicians attempting to install or remove a standard Type A horizontal pin in these situations face frustrating, time-consuming work with limited tool access. The Type F solves this by rotating the pin hole 90° to vertical, allowing the pin to be inserted and removed from above — where access is almost always available. The result: what was a 15-minute struggle becomes a 30-second task.

⭐ الميزات والفوائد الرئيسية
🔼 Vertical Top-Access Pin Hole
Pin inserts from above — no need for lateral access through machine frame or housing walls.
🕑 15-Minute Task → 30 Seconds
Eliminates the frustration of working blind in tight spaces. Pin installation is fast and straightforward.
🔧 One-Hand Operation
Hold the pin alignment with one hand, tap in from above — simple even in awkward positions.
📏 Same Bore Quality as Type A
Identical H7 CNC bore and forging quality. Only the pin hole orientation differs.
⚙ Retrofit Compatible
Direct replacement for Type A yokes on any shaft with a vertical pin hole provision.
💪 No Strength Compromise
The vertical orientation does not reduce pin shear strength — the pin cross-section and material are identical.
🔄 معلومات التوافق
Fits cylindrical shafts with vertical pin hole provision in 20-45 mm range. Works with all implement and gearbox shaft designs that allow vertical pin access. Especially valuable for recessed gearbox inputs, mid-mount equipment, and machines with enclosed PTO housings.
📚 دليل الاختيار
Choose Type F when: The implement shaft is recessed inside a housing and horizontal pin access is restricted. Look at the installation from above — if you have vertical clearance, Type F is your solution.
Shaft Requirement: The shaft must have a vertical pin hole matching the yoke. Many modern gearboxes provide both horizontal and vertical provisions.
🌾 سيناريوهات التطبيق النموذجية
Gearbox input shafts mounted inside enclosed gear housings with limited side access
Belly-mounted mowers and mid-frame implements where the PTO connection is beneath the tractor
Implements with structural members blocking horizontal access to the PTO input shaft
Applications where the pin is removed regularly — vertical access cuts maintenance time dramatically
🛠 دليل التركيب والاستخدام
- Slide yoke onto shaft: Same as Type A — H7 bore provides smooth slip fit.
- Align vertical pin holes: Rotate yoke until the vertical holes in yoke and shaft align (top-down view).
- Insert pin from above: Drop or tap the roll pin through the vertical hole from the top.
- Verify pin seating: Ensure pin passes through both yoke and shaft and is flush with yoke surface.
- تجميع عمود نقل الحركة: Complete the drive line installation.
- For removal: Tap pin upward from below, or use a punch from above if a through-hole is provided.

🌟 آراء العملاء
Andrew C. — 🇦🇺 أستراليا
“Type F solved a persistent headache on our rotary hoe gearbox. The input shaft is recessed 150 mm inside the housing — vertical pin access made all the difference.”
Jürgen W. — 🇩🇪 ألمانيا
“We specify Type F for all our enclosed gearbox designs. Customers love the easy top-access maintenance.”
Renato S. — 🇧🇷 البرازيل
“Simple idea, big impact. Our field technicians no longer dread PTO yoke pin changes on recessed installations.”
Jeff M. — 🇺🇸 الولايات المتحدة
“Changed to vertical pin yokes on our mid-mount mower PTO connections. What used to take 20 minutes now takes 1 minute.”
Isabelle C. — 🇫🇷 فرنسا
“Practical engineering at its best. Same quality as Type A, but the vertical orientation makes maintenance so much easier.”
