Description
Overview:
The Inlet Valve Guide to fit Villiers MK40 Engine (EM749) is a genuine Villiers OEM replacement for the cylinder head. It is a precision-machined metal guide that supports and aligns the inlet valve stem, helping to maintain correct valve clearance, sealing, and timing. By restoring the running surface between the valve stem and guide, it reduces oil consumption and improves compression and starting. Designed specifically for the Villiers MK40, it fits the head in the original location for a straightforward replacement during a rebuild or service. Supplied as unused vintage stock, it may show light tarnish from storage, but this does not affect performance. A reliable choice for keeping classic Villiers-powered machinery running smoothly and efficiently.
Key Features:
- Genuine Villiers OEM part for assured compatibility with MK40 engines
- Part reference EM749 for easy identification and ordering
- Precision-machined metal construction for wear resistance and long service life
- Restores correct valve-to-guide clearance to maintain power and fuel efficiency
- Helps reduce smoking, oil burning, and valve wobble caused by worn guides
- Press-fit design to locate securely in the cylinder head (standard workshop practice)
- May require routine finishing after fitment, such as reaming/honing to final size
- Suitable for full rebuilds or targeted top-end repairs on vintage engines
- Unused vintage stock; cosmetic ageing only, fully functional
Typical Applications:
Used during engine overhauls or repairs to replace worn inlet guides on Villiers MK40 engines found in classic construction, agricultural, and garden machinery. Ideal when diagnosing poor compression, difficult starting, blue smoke, excessive oil use, or noisy valve train. Fit during head refurbishment alongside valve, seat, and spring servicing to restore reliable running and extend engine life.
