🚛 Leyland 3516 / 2518 (Long) — Overview
In commercial vehicle parts catalogs, the description “Leyland 3516 / 2518 (Long)” usually refers to driveline components, steering joints, or propeller shaft assemblies that are:
Compatible with Leyland truck models 3516 and 2518
Longer than standard/regular versions, often to accommodate extended chassis lengths or heavy-duty configurations
This term is most commonly seen in propeller shaft yokes, sliding yokes, and cross assemblies.
🔹 Typical Applications
Propeller Shaft / Driveshaft Components
Sliding Yokes (Long): Allows axial movement in longer driveline setups
Half Yokes / Cross Holders: Designed for extended torque transmission in longer wheelbase trucks
Steering/Pinion Assemblies
Some steering yokes are designated “long” to fit trucks with longer steering column linkages
Differential / Rear Axle
Longer splined yokes or couplings may be required to match the distance between gearbox output and differential input in 3516/2518 trucks
🔧 Why “Long” Matters
Proper Fitment:
A standard-length part may not reach the mating component in long-wheelbase Leyland trucks, leading to improper assembly or driveline stress.
Load & Torque Transmission:
Longer yokes or shafts are often heavier-duty to handle the torque generated by 3516/2518 trucks, which are mid-to-heavy commercial vehicles.
Compatibility:
Only “long” versions fit specific models or configurations, especially trucks with extended chassis or tipper variants.
