3. SLIP SPLINE ISSUES This sliding spline section will need replacement if:

• Longitudinal or radial clearance becomes excessive often causing vibration.

• Damage to the seal can also allow debris to work its way into the splines which can cause binding or seizure. This can also lead to ‘brinelling’ of the universal joints.

1. FLANGE YOKES - can become bent, damaged or even

fractured as a result of excessive torque or shock loads. Wear in the

yoke eyes can cause universal joint caps to rotate leading to

premature failure. The Turret Technology team will replace yokes

that show up unacceptable for optimal operating performance.

2. UNIVERSAL JOINTS - Read notes above for main shaft

3. SLIP SPLINE SECTION - Check notes at top right

1. UNIVERSAL JOINTS - Read notes above for main shaft.

Many steering joints are ’staked in’. The Turret Technology team

has the correct equipment & expertise to stake replacement joints

to original specifications.

2. SPLINE SECTION - Shafts with spline clearance / wear

issues replaced with fine tolerance spline system.

1. UNIVERSAL JOINT ISSUES Inadequate or incorrect lubrication as well as excessive angles or torque loads can lead to conditions such as:

• Seizure

• Burned cross ends

• ‘Spalling’ on bearing surface

• ‘Brinelling’ - grooves in surface

1. UNIVERSAL JOINT

SOLUTIONS The Turret Technology team will assess UJ condition and replace as required to maintain optimal performance. This service includes:

• Following correct UJ assembly procedures

• Fully lubricating greasable joints with premium grade lubricant or upgrading to ‘lube-for-life’ maintenance–free UJ type

• Checking yoke condition/tolerance for wear or misalignment

2. CENTRE BEARING & MIDSHIP ISSUES This is a ‘hotspot’ area to inspect & maintain at regular

intervals as lack of lubrication or other factors can lead to:

• Seized or rough running bearings

• Rubber inserts - split, damaged or perished

• Hanger bracket - bent, damaged or fractures

• Looseness/slop in midship assembly/ retainer causing vibration

** For your assurance of quality, shaft welding is carried out in accordance with BS EN ISO15614 weld procedure and balancing weight attachment

is done by means of a specialised spot welding unit.

4. TUBING Needs to be checked over for:

• Any dents, bends or even missing balance weights.

• Any damage or distortion in the tube section will contribute to im-balance & vibration.

• Welding at tube ends also needs thorough inspection for fractures or separation caused by shock loads or vibration.

Turret Technology will straighten or replace this as required with special grade driveline tubing.

This section can also be lengthened or shortened for various modifications.

2. CENTRE BEARING &

MIDSHIP SOLuTIONS The Turret Technology team when working on this

section of your shaft will:

• Follow correct assembly procedures for these parts

• Assess bearing, rubber insert & bracket condition and replace as required. Fully lubricate greasable bearings. Slotted rubber insert types are often upgraded to solid rubber to provide better long-term performance

• Recommend upgrading older ‘2-bolt’ midship designs to a large single nut type with longer spline length over-coming known looseness and vibration issues.
