Original Triumph fixing references

Where a row lists more than one original reference, its quantity applies to that row as a whole. The references shown in the drawing or contents list do not represent extra bolts in the kit.

The right-side groups contain 6x, 5x and 11x bolts respectively; the left-side group contains 17x. These are the four casing groups identified in the drawing, giving 39x bolts in total.

Important fitment notes

• For Triumph Bonneville & T100 2002–2008 carburettor models with the original engine casing covers shown in the listing drawing.
• Check the exact model and original components before installation. Aftermarket or modified assemblies may require different hardware.
• Engine covers, sprocket cover, gaskets, seals, locating dowels, drain plugs and internal engine components are not included. This is a casing-cover fixing kit, not an engine mounting or internal engine bolt kit.
• Photographs illustrate the hardware and fitting positions. The contents table defines the actual supplied quantities.

Model-specific aftermarket replacements

Biker Bling selects these replacements for the listed original fixing positions. The Triumph references identify the original components replaced, not Biker Bling product codes. These are aftermarket replacement parts, not genuine Triumph-branded components.

Materials and appearance: The supplied bolts are stainless steel. Their appearance may differ from the originals. Material alone does not establish equivalent mechanical strength.

When should you replace these fixings?

• Damaged bolt heads: Inspect corroded heads or worn drive recesses when covers are removed.
• Worn threads: Replace damaged hardware and check the engine mounting threads.
• Cover servicing: Keep the bolts separated by their original cover group during maintenance.

New bolts cannot repair a cracked cover, damaged sealing face or stripped engine thread. A leaking cover also needs its gasket, seals and mating faces checked.

Bolt count: The bolt total excludes the separately supplied anti-seize pack and any separately listed sealing washers.

Fitting information

After assembly: Check the relevant oil or coolant levels and inspect disturbed covers for leaks, following Triumph’s workshop procedure for the work carried out.

Match each replacement to its original location and drawing group. The kit contains several different cover fixings; do not treat them as interchangeable. Align covers and renew gaskets or seals as required by Triumph’s workshop instructions. Start bolts by hand and follow the specified tightening order, torque and thread condition. Do not pull a misaligned cover into place with a bolt. Use anti-seize only where appropriate for the specified procedure, and inspect disturbed joints for leaks after assembly.

For general guidance, read our guide to protecting aluminium mounting threads. Triumph’s workshop procedure takes precedence.

Customer questions

Are locating dowels or drain plugs included?

No. The kit contains the 39x listed cover bolts and one anti-seize compound pack (7 g). Dowels, drain plugs, gaskets and seals are not supplied.

Do multiple references in a row mean extra bolts?

No. The stated quantity is the total for that row. The listed original references identify that fixing allocation and are not additional quantities.
