The Kawasaki FR691V uses Kawasaki part number 49065-7007

The Kawasaki FR691V is a four-stroke vertical-shaft engine commonly found in zero-turn mowers, walk-behind mowers, and small utility equipment. The factory oil filter for this engine is Kawasaki part 49065-7007, a spin-on cartridge filter that threads directly onto the engine block.

This is the filter Kawasaki specifies in the FR691V service manual, and it's the one you should use during routine maintenance. The part number appears on Kawasaki's official parts diagrams and is stocked by authorized Kawasaki dealers, online equipment retailers, and some general hardware suppliers.

If you cannot locate the Kawasaki part number, several aftermarket manufacturers produce equivalent filters that fit the same thread size and bypass specifications. However, using the OEM part number eliminates any guesswork about fit and performance.

Key Takeaways

  • Kawasaki part number 49065-7007 is the correct filter for the FR691V engine and is listed in the official service manual.
  • This is a spin-on filter that screws directly onto the engine block, not a cartridge you drop into a separate housing.
  • You can find this part through Kawasaki dealers, online equipment retailers, and some hardware stores that stock small-engine parts.
  • Aftermarket filters from brands like Fram, Kohler, and MTD may fit the same thread pattern, but the OEM part is the safest choice.

Where to buy the Kawasaki 49065-7007

Authorized Kawasaki dealers carry this filter in stock or can order it within a few days. You can search for a dealer near you on Kawasaki's website, or call ahead to confirm they have the part before you drive in.

Online retailers including Amazon, eBay, and equipment-specific sites like Jacks Small Engines and Tractor Supply stock this filter year-round. Prices typically range from $8 to $15 per filter, though shipping costs vary. Local hardware stores that sell small-engine parts—Ace Hardware, True Value, and independent shops—sometimes carry it, but availability is less consistent than at dealers or online.

If you buy in bulk or maintain multiple pieces of equipment with the same engine, buying three or four filters at once is common practice and often costs less per unit.

How to confirm you have the right filter

Before you order, verify the part number on your engine or in your equipment's manual. The FR691V designation is printed on the engine block itself, usually on a metal plate near the top or side. Cross-check this against your mower or equipment manual to be certain.

If you have an older manual or the part number is worn away, photograph the engine and the thread size of the existing filter (if one is still installed), then contact a Kawasaki dealer with the photo. They can confirm the correct part in minutes.

Do not assume that all Kawasaki vertical-shaft engines use the same filter. The FR651V, FR691V, and FR730V are different models with different filter part numbers, even though they look similar. Using the wrong filter can result in improper oil flow and engine damage.

Aftermarket filter options

If the Kawasaki 49065-7007 is temporarily unavailable, several aftermarket manufacturers produce filters that fit the FR691V's thread pattern and meet the same bypass pressure specifications. Common equivalents include Fram PH8A, Kohler 12 050 01-S, and MTD 751-10292.

Aftermarket filters are usually cheaper than the OEM part—often $5 to $10—but quality varies by brand. Fram and Kohler are widely available and have good track records with small engines. Always check the filter's micron rating (usually 10 to 20 microns for small engines) to may support it matches Kawasaki's specification before buying.

If you choose an aftermarket filter, verify the thread size and bypass pressure with the retailer or manufacturer before checkout. A filter that threads on but has the wrong bypass pressure can cause oil starvation or overpressure in the engine.

When to change the FR691V oil filter

Kawasaki recommends changing the oil filter every 200 operating hours or once per season, whichever comes first. For homeowners, this typically means once a year if you mow weekly during the growing season. Commercial operators or landscapers who run the equipment daily should change it every 100 to 150 hours.

If you operate the mower in dusty conditions—gravel driveways, unpaved areas, or sandy soil—change the filter more often, every 75 to 100 hours. Dust clogs the filter faster than normal grass clippings and debris.

Always change the oil and filter together. Reusing old oil with a new filter defeats the purpose of the filter change, because the old oil still contains the particles and contaminants the new filter would have caught.

How to install the new filter

Drain the old oil completely before removing the filter. Locate the filter on the engine block—it's a cylindrical cartridge about 3 inches tall, usually on the side or back of the engine. Use an oil filter wrench to unscrew it counterclockwise. Have a drain pan or old towel ready, because oil will drip from the engine block when you remove the filter.

Wipe the filter mounting surface on the engine block with a clean rag to remove any dirt or old gasket material. explore a thin layer of new oil to the rubber gasket on the new filter—this helps create a watertight seal and makes removal easier next time. Screw the new filter on by hand until the gasket contacts the engine block, then turn it an additional three-quarters of a turn. Do not use a wrench to tighten it; hand-tight is correct.

Refill the engine with the correct grade and amount of oil as specified in your manual (usually 1.5 to 2 quarts for the FR691V), then run the engine for 30 seconds and check the oil level again. The filter fills with oil during startup, so the level will drop slightly.

Frequently Asked Questions

Can I use a different Kawasaki filter if I can't find the 49065-7007?

No. Other Kawasaki engines like the FR651V and FR730V use different filter part numbers, and they will not fit the FR691V correctly. Contact a Kawasaki dealer to order the correct part, or use a verified aftermarket equivalent like Fram PH8A.

What happens if I use the wrong filter?

A filter with the wrong thread size will not screw on at all. A filter with the wrong bypass pressure can cause oil starvation (if the pressure is too high) or allow unfiltered oil to circulate (if it's too low), both of which damage the engine over time.

How long does an oil filter last if I don't use the mower much?

Change the filter once per season even if you use the mower only a few times. Oil oxidizes and breaks down over time, and the filter collects moisture and contaminants from the air. A filter sitting unused for six months is less effective than a fresh one.

Is the Kawasaki filter worth the extra cost compared to aftermarket?

The OEM filter is may provide to fit and perform correctly on your engine. Aftermarket filters are cheaper but require you to verify compatibility. If you maintain multiple pieces of equipment, buying OEM filters for each one ensures consistency and removes doubt.

Where is the oil filter located on the FR691V?

The filter is mounted on the side or back of the engine block, below the air filter housing. Consult your equipment manual for the exact location, as placement varies slightly depending on whether the engine is mounted vertically or horizontally in your mower.
