About 5240530830 - Valve Guide
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
The 5240530830 catalog marking includes 19.00 R6 H7 and a finished-machining description. Do not treat those tokens as a complete dimensional drawing. Confirm the mating valve, cylinder-head bore, and any required finishing work for the offered guide.
Technical Notes: Valve train
Valves, guides, seats, springs, and rocker components control gas exchange in the cylinder head. Wear in the valve train shows up as compression loss, rising exhaust temperatures, or changes in valve clearance between service intervals.
When This Type of Part Is Usually Replaced
- valve clearance changes quickly between adjustments
- compression is low on one or more cylinders
- valves or seats show burning, pitting, or recession during head overhaul
Checks Before Ordering
- Valve guides and seats are matched to the valve stem and head; order them per cylinder head
- Replace valve stem seals whenever valves are removed
- Inner and outer valve springs are usually separate part numbers
Technical Data Status
Published catalog details help identify this part, but they are not a controlled drawing for the item offered. Measurements that are not shown here still need confirmation before substitution or order.
- Catalog marking: FERTIG BEARBEITET, 19.00 R6 H7. Confirm which dimensions and tolerances it describes.
