Why this one
Spark plug sockets and T bar (TEXTB05)
The plug comes out and goes back in at every tune up. Three spark plug sockets, 14, 16 and 21 mm, with their own T bar handle in a foam tray, pull the old plug and refit the new one.
Ratchet and step up adapter (3800L, M380036M)
The 3/8 inch drive long arm ratchet turns the plug sockets. The magnetic 3/8 to 1/2 inch step up adapter puts the 1/2 inch drive filter wrench on that same ratchet.
Filter wrench and drain plug keys (9120, DP1012, DP0812)
Oil comes out first. The chain type wrench removes spin-on filters up to 120 mm (4.7 inch) across, and the double ended keys fit the recessed hex and square socket drain plugs that a socket or wrench cannot grip.
Feeler gauge for the plug gap (FG20200)
A new plug has to be checked before it goes in. The metric feeler gauge set, 0.05 to 1.0 mm, measures the gap against the engine manual figure.
Read the full description
Oil, filter and spark plug are on every small engine tune-up: drain the oil, change the filter, refill, then pull, gap and refit the plug. This kit has 14, 16 and 21 mm plug sockets with a T bar, a 3/8 inch drive long arm ratchet, a chain type oil filter wrench, two double ended drain plug keys for hex and square socket drain plugs, and a metric feeler gauge.
Bring the engine oil, a drain pan, a new spark plug and a new oil filter if your engine has one. Bring a wrench or socket to turn the drain plug keys. A drain plug with an outside hex head needs a socket or wrench of its own size. Check the engine manual for the drain plug type and the plug gap, and use a plug gap tool to set it.
In this bundle:
- 3/8 inch drive T bar spark plug socket set in a foam tray (TEXTB05)
