Important Fitment Information
The strongest cross-reference is Honda 14670-GBJ-M30 (25T), which supersedes 14670-035-030. Because the uploaded Shopify images could not be directly inspected, exact fitment of every supplied tensioner component must still be checked against the original engine.
Do not order by engine capacity or model name alone. Honda used different tensioner rods, springs and spindles across model years even where the 25T guide sprocket is shared.
Before ordering, compare the original sprocket tooth count, centre/thread arrangement, tensioner rod, spring, roller/guide parts and all supplied pieces with the product photographs.
What's Included
Oil-pump/cam-chain guide sprocket and cam-chain tensioner service components as supplied. The exact individual component count could not be independently confirmed from the Shopify export, so the product photographs should be used as the final contents reference.
Installation
These are internal engine timing and lubrication components. Correct cam-chain routing, tensioner assembly and oil-system operation must be confirmed before the engine is run. Professional installation is recommended if the correct Honda small-engine procedure is not known.
