Dipstick Extension Kit
One of Don Moyer’s first Atomic 4 kit upgrades, and loved by many of our customers. This low profile kit enables you to check your oil level without having to reach back over your engine. The extension tube attaches over the original short dipstick tube by a small Allen head set screw, or convenient thumb screw. All hardware included.
With an overall length of only 3.5”, this tool is designed to remove the impeller from the shaft of your MMI 502 flange or 501 pedestal pump with the pump mounted on the engine or removed from the engine. With a little practice, you can remove an impeller “in the blind” using only one hand if necessary, which is very convenient when working in the most restrictive on-board installations. Our puller will also work on Oberdorfer 202M and 201M series pumps.

External fastener kit
Anyone who has rebuilt an Atomic 4 can relate to the frustration of not having the right fastener when you need it, since many are too rusted, or broken after disassembly to reuse. The External Fastener Kit contains the Grade 8 hardened bolts, nuts and washers needed for the external reassembly of your Atomic 4. Conveniently labeled in a multi-bin organizer, this kit includes the hard to find “odd” bolt lengths and custom undersized brass washers not readily available at your local hardware store.

Shifting cable bracket (starboard side mount)
This bracket is designed to be mounted on the starboard (distributor) side of the aft housing using two of the access cover’s 5/16” retaining bolts (mounting bolts and washers included) also available in port side mount. When used with our MMI clevis and a standard 6400 series cable, and the cable clamp in the outermost mounting holes; approximately 2” travel is provided on each side of the nominal neutral point of the shifting lever. This mounting configuration allows installing the clevis pin in the outermost hole on the shifting lever for best mechanical advantage with a minimum of 5/8” spare cable travel beyond the forward and reverse positions of the shifting lever. NOTE: The nominal neutral position of the shifting lever is approximately 10 degrees forward of the straight up position (approximately the 1:00 position when viewed from the side). If you’re using a 6300 series cable (with only 3” total travel), it may be necessary to use the lower hole on the engine shifting lever. In this case, the clamp and all three shims can be mounted along the bottom side of the mounting plate to align the cable with the lower hole on the shifting lever (clevis and shifting cable not included).
