What the Bobcat 942607 air filter does and which machines use it
The Bobcat 942607 is an engine air filter that fits several Bobcat compact equipment models, primarily skid-steer loaders and compact track loaders built in the mid-2000s through early 2010s. It removes dust, dirt, and debris from the air before it enters the engine, which keeps the engine running cleanly and prevents premature wear.
This filter is a direct replacement part, meaning Bobcat designed it specifically for certain serial number ranges and model years. If you own a Bobcat S570, S590, S630, S650, S750, S770, or T650 in the years this filter was produced for, the 942607 is the correct part number to order. You can confirm your machine's compatibility by checking your operator manual or calling a Bobcat dealer with your serial number.
The filter itself is a cylindrical cartridge with pleated paper media inside a plastic or metal housing. As air passes through, the pleats trap particles. Over time, the pleats become clogged, which restricts airflow to the engine and reduces fuel efficiency and power output.
Key Takeaways
- The Bobcat 942607 is an engine air filter for mid-2000s to early 2010s Bobcat skid-steer and compact track loaders; check your serial number to confirm it fits your machine.
- A clogged filter reduces engine power and fuel economy, so replacing it every 500 to 1,000 operating hours (or annually, whichever comes first) keeps your machine running efficiently.
- Replacement takes 10 to 15 minutes and requires only a wrench or socket set; the filter housing is usually located on top of or to the side of the engine.
- You can buy the 942607 from Bobcat dealers, online equipment parts suppliers, or general industrial parts distributors; prices vary but typically range from $40 to $80 per filter.
- Reusing or cleaning a disposable cartridge filter is not recommended because the pleats cannot be fully restored and a partially clogged filter still restricts airflow.
When to replace the 942607 filter
Most manufacturers recommend replacing an engine air filter every 500 to 1,000 operating hours, or once per year if you use the machine seasonally. If you operate your Bobcat in dusty conditions—such as demolition sites, gravel pits, or dry fields—you may need to replace it more often, possibly every 250 to 500 hours.
A visual inspection is the most reliable way to know if replacement is due. Open the filter housing and look at the pleats. If they are visibly caked with dust or dirt, or if you cannot see light through the filter when you hold it up to a lamp, it is time to replace it. A filter that looks gray or tan is still working; one that looks black or is matted down is overdue.
Ignoring a clogged filter costs you fuel economy and engine power. A severely restricted filter can also cause the engine to run rich (burning too much fuel) or overheat, which shortens engine life. Replacing the filter on schedule is one of the cheapest maintenance tasks you can do to protect your investment.
How to replace the 942607 filter step by step
Start by locating the air filter housing on your machine. On most Bobcat skid-steers and compact track loaders, it sits on top of the engine or mounted to the side of the engine compartment. Consult your operator manual if you cannot find it when ready.
Once you have located the housing, follow these steps:
- Turn off the engine and let it cool for at least 10 minutes.
- Unbolt the filter housing cover using a wrench or socket set. The cover is usually held by two to four bolts.
- Lift off the cover and set it aside on a clean surface.
- Grasp the old filter cartridge by its plastic or metal end cap and pull it straight out of the housing.
- Wipe the inside of the housing with a clean, dry cloth to remove any loose dust or debris.
- Insert the new 942607 filter into the housing, making sure the rubber seal at the base sits flush against the bottom of the housing.
- Replace the cover and tighten the bolts in a crisscross pattern (like tightening a wheel) to may support even pressure. Do not over-tighten.
- Start the engine and listen for any air leaks around the housing. If you hear a hissing sound, turn off the engine and re-tighten the bolts.
The entire job typically takes 10 to 15 minutes. Keep the old filter for disposal; many retailers that sell filters will take used ones for recycling.
Where to buy the Bobcat 942607 filter
You have several options for purchasing this filter. Bobcat dealers stock the 942607 and can order it if they do not have it in stock; this is the most reliable route if you want to be certain the part is correct for your machine. Dealers can also verify compatibility by serial number if you are unsure.
Online equipment parts suppliers such as eBay, Amazon, or specialized Bobcat parts websites often carry the 942607 at competitive prices. Shipping times vary, so check the listing before ordering if you need the filter urgently.
General industrial parts distributors and farm equipment suppliers may also stock this filter under the Bobcat part number or under a cross-reference number. Calling ahead to confirm availability saves a trip.
Prices for the 942607 typically range from $40 to $80 per filter, depending on the seller and whether you are buying one or multiple units. Buying two or three at once can sometimes lower the per-unit cost and ensures you have a spare on hand for future maintenance.
Understanding air filter cross-references and alternatives
The Bobcat 942607 may have a cross-reference number from other manufacturers. For example, some aftermarket suppliers list equivalent filters under their own part numbers. These filters have the same dimensions, seal type, and filtration rating as the 942607, so they work as direct replacements.
Before buying a cross-reference filter, confirm that the dimensions match: the outer diameter, inner diameter, and height should be identical to the original. The seal material should also match (usually rubber or foam). If the dimensions or seal type differ, the filter may not seal properly in the housing, allowing unfiltered air to bypass the media and reach the engine.
Aftermarket filters are often less expensive than OEM (original equipment manufacturer) Bobcat filters, but quality varies. Reputable aftermarket brands use the same pleated paper media and construction methods as OEM filters. Extremely cheap filters may use thinner media or lower-quality seals, which can fail sooner or allow particles to pass through.
Troubleshooting common air filter problems
If you replace the filter and the engine still feels sluggish or fuel economy does not improve, the problem may not be the filter itself. Check that the filter housing cover is sealed tightly and that no bolts are loose. A loose cover allows unfiltered air to enter the engine, which defeats the purpose of the new filter.
If you notice oil or moisture inside the filter housing, the engine may be overfilled with oil or the crankcase ventilation system may be malfunctioning. Wipe out the housing and replace the filter, but also check your oil level and top it up only to the full mark on the dipstick. If oil continues to accumulate in the housing, have the ventilation system inspected by a technician.
A filter that clogs very quickly (within 50 to 100 hours of installation) suggests you are operating in extremely dusty conditions or that the housing seal is compromised and allowing unfiltered air to enter. If the seal is damaged, the housing itself may need replacement. If conditions are straightforward very dusty, consider replacing the filter more frequently or upgrading to a pre-filter (a secondary filter that catches larger particles before they reach the main filter).
Frequently Asked Questions
Can I clean and reuse the 942607 filter instead of replacing it?
No. The 942607 is a disposable cartridge filter with pleated paper media. Once the pleats are clogged, they cannot be fully restored by cleaning. Even if you blow compressed air through the filter or wash it, the media remains partially blocked and will restrict airflow. Replacing it is the only reliable option.
What happens if I run my Bobcat with a clogged air filter?
A clogged filter reduces the amount of air reaching the engine, which forces it to burn fuel inefficiently and work harder to produce the same power. Over time, this increases fuel consumption, reduces engine performance, and can cause overheating. Prolonged operation with a severely clogged filter may damage the engine.
Is the 942607 filter the same for all Bobcat models?
No. The 942607 fits specific Bobcat models and serial number ranges from the mid-2000s to early 2010s. Newer or older Bobcat machines use different filter part numbers. Always verify your machine's serial number and model year before ordering to may support you get the correct filter.
How much does the Bobcat 942607 filter cost?
Prices typically range from $40 to $80 per filter, depending on whether you buy from a Bobcat dealer, an online parts supplier, or an aftermarket distributor. Dealer prices are usually higher but include the assurance that the part is genuine. Buying multiple filters at once may lower the per-unit cost.
Do I need any special tools to replace the 942607 filter?
No. You need only a basic wrench or socket set to unbolt the filter housing cover. The filter cartridge itself pulls out by hand. No special tools or technical knowledge is required, making this a straightforward maintenance task you can do yourself.
