The Bobcat 942607 uses part number 6679498 as its OEM air filter

The Bobcat 942607 is a compact track loader, and its air filter part number is 6679498. This is the original equipment manufacturer (OEM) part that Bobcat specifies for this model. You can order it directly from Bobcat dealers, through online equipment parts retailers, or from general industrial suppliers that stock Bobcat components.

The 942607 air filter is a cartridge-style element that sits inside a plastic or metal housing on top of the engine. Replacing it is a straightforward task that takes 10 to 15 minutes and requires no special tools beyond a wrench or socket set to remove the housing cover.

Bobcat recommends checking the air filter every 250 operating hours and replacing it when it becomes visibly clogged with dust or debris. In dusty conditions—such as demolition work or dry excavation—you may need to replace it more often. A clogged filter reduces engine power and increases fuel consumption.

Aftermarket filters and cross-reference options

Several aftermarket manufacturers produce air filters that fit the 942607 housing. Common cross-reference part numbers include filters from Donaldson, Baldwin, and Fleetguard. These filters are usually 20 to 40 percent cheaper than the OEM 6679498 but may have different pleating density or media thickness.

Aftermarket filters work mechanically in the 942607 housing, but Bobcat does not warrant them, and some dealers will not service your machine if you have installed a non-OEM filter. If you use an aftermarket part, keep the receipt and document the replacement date and hour meter reading in case a warranty dispute arises later.

To find cross-reference numbers, enter the 6679498 into a parts interchange database such as Parts Town or the manufacturer's own cross-reference tool. Always verify the dimensions and connection type before ordering, because air filter housings vary slightly between Bobcat models.

Step-by-step replacement process

First, locate the air filter housing on top of the engine. It is a cylindrical or rectangular plastic or metal canister with a cover held on by two to four bolts or a clamp band. Stop the engine and allow it to cool for at least five minutes.

Remove the bolts or loosen the clamp band using a wrench or socket. Lift the cover straight up and set it aside. The old filter cartridge will be inside; grasp it by the center and pull it straight out. Do not shake it or tap it, because loose dust can fall into the engine.

Wipe the inside of the housing with a clean, dry cloth to remove any settled dust. Insert the new 6679498 filter cartridge straight down into the housing, making sure the rubber seal at the base sits flush against the housing floor. Replace the cover and tighten the bolts or clamp band firmly but not so tight that you crack the plastic housing.

Start the engine and listen for any air leaks around the housing cover. If you hear a hissing sound, stop the engine and tighten the bolts another quarter turn. Record the date, hour meter reading, and part number in your maintenance log.

Cost and availability timeline

The OEM Bobcat 6679498 air filter typically costs between $35 and $65 depending on the retailer and your location. Aftermarket equivalents range from $20 to $40. Shipping adds $5 to $15 if you order online.

Bobcat dealers usually have the 6679498 in stock at their service departments. If not, they can order it and have it within one business day if you call before noon. Online retailers ship within three to seven business days depending on your distance from their warehouse.

If your 942607 is under warranty and you need the filter replaced, contact your dealer. Many dealers will replace it at no charge during the first 500 operating hours or as part of a scheduled service interval.

Storing spare filters and maintenance records

Keep one spare 6679498 filter on hand if you operate the 942607 regularly. Store it in a clean, dry location away from direct sunlight, which can degrade the rubber seals over time. A sealed plastic bag or cardboard box works well. Spare filters do not expire, but they should be installed within two to three years of purchase to may support the seals remain pliable.

Write the purchase date and part number on the filter box with a permanent marker. When you install it, note the hour meter reading and date in your machine's maintenance log. This record helps you track replacement intervals and can be important if you sell the machine or need to prove warranty compliance.

Frequently Asked Questions

Can I clean and reuse the 6679498 filter instead of replacing it?

No. The 6679498 is a disposable cartridge filter designed for single use. Attempting to clean it by blowing compressed air through it can damage the pleated media and create small tears that allow unfiltered air into the engine. Replacement is the only safe option.

What happens if I run the 942607 with a clogged air filter?

A clogged filter restricts airflow to the engine, reducing power output and increasing fuel consumption. Over time, it can allow dust to bypass the filter and enter the engine, causing premature wear on piston rings and cylinder walls. Replace the filter as soon as you notice reduced performance or visible dirt buildup on the housing.

Is the 6679498 the same filter for all Bobcat 942607 models?

The 6679498 is the standard filter for the 942607 compact track loader. However, if your machine has been modified or retrofitted with a different engine, the filter part number may differ. Check your operator's manual or contact your Bobcat dealer to confirm the correct part number for your specific serial number.

Can I use a different brand filter if I cannot find the 6679498 in stock?

Yes, but verify the cross-reference number first. Many aftermarket filters fit the 942607 housing, but you must confirm the dimensions, seal type, and connection method match. Contact the aftermarket manufacturer's technical support line with your machine's model number to may support compatibility before ordering.

How do I know when the air filter needs replacement if I do not track operating hours?

Inspect the filter visually every two to four weeks during regular use. If the pleated surface appears gray or brown with visible dust, or if you notice reduced engine power or increased fuel consumption, replace it. Do not wait for the hour meter; visual inspection is a reliable guide in dusty environments.
