FAQs
Q1: Will this cover fit without modifications?
A1: Yes — it is made to replace the stock tappet/inspection cover on UCE engines, so mounting points and dimensions remain identical.
Q2: Can I use it on a BS6 J-Series / newer engine?
A2: Unlikely — this part is intended for UCE platform engines. J-Series geometry differs, so confirm before using.
Q3: Is the “1901” branding durable?
A3: Yes — it’s engraved into the anodised aluminium, so it should resist normal wear and cleaning.
Q4: Will it affect engine performance or oil flow?
A4: No — it matches OEM design and is only a cosmetic cover replacement, not altering internal engine function.
Q5: Does this void warranty?
A5: No — it's a genuine RE accessory, and installed properly should not void the engine warranty, though confirm with local dealer.
