Quantities are the contents of the single supplied kit. Alternative original references identify fitting positions and do not mean duplicate groups are supplied. The diagrams use representative bolt symbols; the contents table gives the supplied quantity.

The combined alternator, crank and starter cover group contains 32 bolts, including the replacement allocated to crank-cover item 29 where fitted. Item 29 is included within that group, not an extra bolt. One later cover arrangement uses fewer bolts and leaves one spare.

The sprocket-cover group contains three bolts at item 2 and two at item 30. The copper pump washer is cooling-system item 50; radiator washer item 4 is excluded.

Ordering and model identification

Choose this kit for the listed Triumph Sprint ST 1050 2005–2011 with its matching original covers. There is no engine-number dropdown. If the motorcycle has a replacement engine, modified covers or an uncertain model identity, check the fitted arrangement before ordering.

Keep the original bolts identified by position during removal. Match each replacement to its intended location. Any unused bolt is a spare for the alternative cover arrangement; it is not an instruction to add a fixing.

Model-specific aftermarket replacements

Supplied bolts are stainless steel socket cap head replacements. Replacement head style and individual specifications may differ from the original fixings. Check original positions, thread engagement, head clearance and sealing arrangements before fitting.

Original Triumph references and diagram numbers identify original fitting positions. Supplied components are Biker Bling aftermarket replacements, not genuine Triumph-branded parts.

The main hardware image and separate hardware photographs are representative illustrations. Use the contents table and model-specific diagrams to identify supplied positions. The motorcycle photograph is for identification only; the motorcycle is not supplied.

When should you replace engine cover bolts?

Inspect fixings when working on the listed covers. Missing bolts, damaged heads, worn threads and corrosion can prevent correct reassembly. Check the covers and mounting threads too; replacement bolts cannot repair a cracked cover or stripped thread.

Read our guide to when motorcycle bolts should be replaced.

Fitment and coverage

For the listed model and year range with matching original covers. Similar capacity or registration year alone does not establish compatibility with another motorcycle model.

Only the listed external cover, pump-casing and sump positions are included. Cam and breather covers, crankcase joining bolts, internal engine hardware, radiator, thermostat, coolant-elbow hardware and unlisted brackets are excluded. Covers, gaskets, seals, dowels, oil filters, sump drain plugs and sump drain washers are not supplied. Listed pump bolts and the copper washer are included.

Fitting information

Bag fittings by area and keep each original bolt identified by position. Follow Triumph’s workshop procedure for the exact engine and cover, including fluid handling, sealing arrangements, tightening sequence, torque and specified thread condition. Start correctly matched bolts by hand. Do not force a bolt or use it to pull a misaligned cover into place.

The anti-seize pack is not an instruction to lubricate every fixing. Use compounds only where appropriate to the workshop procedure. Check disturbed sealing arrangements and fluid levels before returning the motorcycle to use.

Read our guide to fitting stainless steel motorcycle bolts. Triumph’s workshop instructions take precedence.
