Usage Features

The Holland 17 Series Fifth Wheel is designed for robust and reliable operation in heavy-duty trucking applications. Key usage features, as implied by the manual's content, include:

Standard and Air Release Options: Provides flexibility in coupling and uncoupling operations, with the air release mechanism offering potentially faster and less physically demanding disengagement.
Generation Identification: The manual distinguishes between Generation 1 and Generation 2 fifth wheels based on the presence of a front lock insert and ear shape (narrow, flat for Gen 2; rounded for Gen 1). This allows for precise maintenance and selection of appropriate rebuild kits, ensuring compatibility and optimal performance.
Adjustable Lock Mechanism: The fifth wheel features an adjustable lock mechanism, allowing for fine-tuning to minimize free play between the lock and the kingpin. This is critical for maintaining vehicle control and preventing tractor-trailer separation.
Replaceable Components: The design incorporates replaceable components such as pocket inserts, upshock cushions, and various pins and springs, facilitating repair and extending the lifespan of the fifth wheel.

Maintenance Features

The manual is primarily a guide for maintenance and repair, emphasizing critical aspects to ensure safety and longevity:

Safety Instructions: General safety instructions are prominently featured, including warnings against improper servicing, the importance of trained technicians, and adherence to OSHA or equivalent safety regulations. Specific warnings highlight the risks of component failure, personal injury, and tractor-trailer separation if instructions are not followed.
Inspection Criteria: Clear criteria are provided for inspecting the top plate for cracks and flatness, and for checking the elongation of lock pin, adjusting pin, and bracket pin holes. This ensures that severely worn or damaged components are identified and replaced.
Lubrication Requirements: The manual specifies lubrication points and the type of lubricant (Never-Seez® and grease) for various moving parts, such as the cam, cam track slot, shoulder bolts, adjusting pin, lock pin, and handle, to ensure smooth operation and prevent wear.
Use of Original Parts: SAF-HOLLAND® explicitly requires the use of only SAF-HOLLAND Original Parts for replacement, emphasizing their role in ensuring maximum performance, durability, and warranty validity.
Specialized Tools: The necessity of specialized service tools (Kingpin Gage, Lock Gage, Kingpin Lock Tester) for accurate adjustment and verification of the locking mechanism is highlighted, underscoring the precision required for proper maintenance.
Online Resources: The manual directs users to www.safholland.us for updates, technical support locations, and aftermarket parts catalogs, providing ongoing support for product maintenance.
Pocket Insert Management: Instructions are given for handling pocket inserts during top plate removal and installation, including the use of double-face tape to secure them, preventing loss and potential hazards.
Adjustment Verification: The manual outlines a rigorous process for adjusting the fifth wheel and verifying proper lock engagement and minimal free play using a lock tester, ensuring the fifth wheel is operating correctly before use.
