Carquest 85290, 84723, 84418, and 87033 cover most of the hydraulic and transmission filter work on John Deere, Case, Hitachi, Komatsu, and Caterpillar equipment — but only when your Carquest filter cross-reference is actually right. 85290 lines up with WIX 51290 and Donaldson P550416. 84723 runs a similar M24 x 1.5 thread in a different can. 84418 moves up to a 1 3/4-inch mount for heavier iron. Full specs, verified crosses, and the mismatch that trips up most buyers are below.
Fast Cross Reference by Filter Type
Start with the filter type when using any Carquest filter cross-reference chart, then confirm thread size and length before ordering. Numbers that look similar often fit totally different applications, so checking size saves you a return trip.
Here is a snapshot of the most common Carquest numbers used on diesel machines:
| Carquest No. | Filter Type | Donaldson/WIX Match | Common Thread |
|---|---|---|---|
| 85495 | Hydraulic spin-on | HX15916 | 1 3/8-12 |
| 85290 | Hydraulic spin-on | P550416 / WIX 51290 | — |
| 85243 | Hydraulic spin-on | HX11089 | 13/16-16 |
| 84723 | Transmission/hydraulic | — | M24 x 1.5 |
| 84418 | Hydraulic (premium) | — | 1 3/4 |
| 87769 | Air (safety/inner) | WIX 42769 | — |
| 87034 | Air (inner, radial seal) | — | — |
| 86195 / 86361 | Fuel/water separator | P555095 / FF5095 | — |
| 86407 | Fuel spin-on | FX53084 | 1-14 |
| 86528 | Fuel (2 µm) | BF7633 / WIX 33674 | 1-14 |
Match the thread first, then the length, then the micron rating. Three checks beat one guess every time.
Hydraulic Filter Matches by Brand
The place most owners get burned is hydraulic filtration, because a filter can thread on perfectly and still be the wrong micron rating for the pump. Use the tables below as a starting point and always double-check against your machine serial number.
Case, New Holland, and John Deere
Carquest 85290 is one of the widest-fitting hydraulic spin-ons on the market. It crosses to Donaldson P550416, WIX 51290, Fleetguard HF6317, and NAPA 1290. You will find it on Case backhoes, Hitachi excavators, JCB loaders, John Deere tractors, Komatsu dozers, and plenty of ZF transmissions.
Common original numbers it replaces:
- Case 1203438H1, 185161A1, 299380A1, S301612
- John Deere AT102377, AT140030, AT168989
- Hitachi 4230376, 4286837, AT168989
- Komatsu 252116, BW252116
- JCB 4801601, O&K 1499397, Terex 9398040
For ZF-style powershift transmissions on Case and New Holland machines, Carquest 84723 is the one you want. It uses an M24 x 1.5 stud thread and crosses to ZF 050132315401, Case 332202A1, and John Deere AT336140. Grab a reliable hydraulic transmission filter from a trusted aftermarket source, and you will keep your powershift running smoothly.
Caterpillar and General Equipment
Carquest 85495 is the go-to spin-on for mid-size Cat machines, Fiat-Allis loaders, Daewoo excavators, Kawasaki wheel loaders, and Steiger tractors. The 1 3/8-12 thread and 9 17/32 inch length match Donaldson HX15916.
For heavier Cat and Deere units running a premium filter head, Carquest 84418 fits bases 99261 through 99265. It stands 11 17/32 inches tall with a 1 3/4 thread and is a solid pick for high-flow systems.
Agricultural owners running Vermeer, Rayco, or Zetor equipment should look at Carquest 85243, which crosses to HX11089 and handles the smaller 13/16-16 thread found on many compressor and PTO circuits.
Air Filter Equivalents for Diesel Engines
Air filtration on a diesel engine is where a cheap mistake becomes an expensive repair. A loose seal or the wrong-length canister lets dust bypass the element, and dust kills rings and liners fast.
Safety and Inner Air Elements
The Carquest 87769 is a secondary air filter, so it sits inside the primary and works as a backup during service. It fits a long list of equipment because the industry settled on a few standard canister sizes. These include:
- Bobcat 6598362
- Kubota 1561211180, 1738111180, 1738111181, 6833543620
- Komatsu 3EB0225550, Z760225550
- AGCO and Massey Ferguson 1043327M91
- Kobelco 2446U244S1, 2446U299S2
- Caterpillar 3I0167
- New Holland Agriculture 86504143
It crosses to Donaldson P123160, Baldwin PA2489, and WIX 42769. Dimensions run 2.59 inch OD, 3.05 inch sealing OD, and 255.9 mm length. Pair it with the matching primary and replace both at the service interval.
Carquest 87034 is a radial-seal inner element at 10 25/32 inches long. It replaces Caterpillar 108-0672 and John Deere AT175345, and shows up on Barber-Greene pavers plus a range of Cat and Deere machines.
For Case excavators such as the 9033, 9040, and 9060, Carquest 87216 is a primary air filter option that crosses to WIX 42216 and Fleetguard AF975M.
Compact Tractor and Skid Steer Air Filters
Compact John Deere operators should know about Carquest 87033 and 87033XP. These fit the 1023E, 1025R, and the 240–320 skid steer family, cross-referencing AT338105, AT336803, KV16428, AP33330, and AP33331. A fresh compact tractor air filter keeps horsepower where it belongs, especially in dusty cutting and mowing tasks.
Fuel Filters and Water Separators
Diesel fuel quality varies, and a water separator is your first line of defense against injector damage. The Carquest fuel lineup covers everything from compact Bobcat engines to Tier 4 trucks.
Bobcat, Case, and New Holland Diesels
Carquest 86195 and 86361 are the standard fuel filter spin-ons for Bobcat skid steers, older Ford diesels, and many Case and New Holland units. They cross to Donaldson P555095, Fleetguard FF5095, Baldwin BF1235, BF1261, and BF7608, and WIX 33192 and 33195.
The number list looks like this:
| Brand | Original Number |
|---|---|
| Bobcat-Melroe | 4121609, 4121609B |
| Case | E7HZ9365B, E97454 |
| New Holland | 3958768, 3961258, 89613344, 9613344 |
| Sandvik/Eimco | 69008935 |
Keep a spare on the shelf. Water in the bowl is a sign to drain and replace, not top off and hope.
Heavy Duty Fuel and Water Separators
For higher-capacity systems like FASS lift pumps, Carquest 86528 is a 2-micron water separator with a 1-14 thread, matching Baldwin BF7633 and WIX 33674. If you run a 10-micron primary stage, Carquest 85724 with a 1 1/2-16 thread pairs with Baldwin BT372-10, Hastings HF779, and Fram P8024.
A general-purpose fuel/water spin-on, Carquest 86407, has a 1-14 thread and 7 7/16 inch length, crossing to FX53084. It is a frequent pick for diesel generator sets and smaller industrial engines.

A quick note before you order: part number lists change over time as manufacturers revise castings and media. If your machine serial number is close to a model transition year, pull the plate and confirm the suffix before ordering a case of filters.
Final Thoughts
Before ordering, match the serial number on the machine against the number stamped on the old filter — a Carquest filter cross-reference chart is only as good as the serial-number check behind it. For Deere, Hitachi, Case, and Komatsu hydraulic and transmission filters, FridayParts stocks the direct crosses listed above at fleet pricing, with same-day shipping on most part numbers. Keep the old filter around until the new one has run a full heat cycle without leaking.
