Left-Hand Crankcase Cover Bolt & Seal Repair Kit for Bullet 350/500 UCE, Electra 350 UCE, Classic 350/500, Thunderbird & Continental GT 535 – Genuine Royal Enfield 888115

Royal Enfield 888115 is a genuine OEM bolt and seal repair kit for the left-hand crankcase cover. Official parts sources identify it as BOLT&SEAL REPAIR KIT-LH CR.CASE COVER CL, and multiple checked sources place it in the left-hand crankcase / left cover parts family across older Royal Enfield UCE and GT applications.

This is the correct replacement when the left-hand crankcase cover bolt and sealing points are damaged, stripped, leaking, worn, or being repaired during clutch-side / left-cover service. Buyers usually search for this part as LH crankcase cover bolt repair kit, left cover bolt and seal kit, clutch side cover repair kit, Classic 350 left crankcase cover kit, or Bullet UCE LH cover bolt kit. This page should speak clearly to that buyer need: this is a repair kit for the left-hand crankcase cover bolt and seal area, not the full cover, not the clutch operating lever, and not a random hardware kit.

The strongest surfaced fitment support is broad across older Classic, Bullet UCE, Electra UCE, Thunderbird, and Continental GT Continental GT, NTB 350, NTB 500, Bullet 500 UCE, Bullet 350 UCE KS/ES, Electra 350 UCE ES, Classic 350, and Classic 500 EFI for 888115.

Before you buy: match 888115, confirm you need the left-hand crankcase cover bolt & seal repair kit, and compare the repair location on your LH engine cover before ordering.
