Primary filter note
For the Massey Ferguson 145V, the listed primary air filter part number is 3703703M91. Match the number before buying because air cleaner setups can vary by engine, serial range and market.
Outer filter note
The listed outer air filter part number is 7068069M1.
Safety filter note

Fitment note
Listed dimensions: Length: 9.2 in | Outside diameter: 4 in | Inside diameter: 2.5 in. Use dimensions as a second check, not as the only buying method.
Filter size note
The listed dimensions point to a mid-size element length at 9.2 in and normal outside diameter at 4 in. Use that as a fitment sanity check against the old filter.
Power range note
With a 145 hp engine class, the horsepower is high compared with the listed element size, so restriction checks matter more. Watch for weak pull, smoke or heat under load before waiting for the full 400-hour guide.
Engine airflow note
Displacement and horsepower together explain airflow demand better than either one alone, but the air-cleaner housing still proves fit.
Cross-reference note
Possible cross-reference numbers found for the Massey Ferguson 145V: 1032762M1, 1807255M1. Treat these as secondary checks after the primary filter number.

Massey Ferguson 145V Air Filter FAQs
Can the Massey Ferguson 145V air filter become a restriction under load?
The combo is a practical warning system. If the element is packed, damaged or not sealing, the engine can lose airflow long before the filter looks catastrophic.
Should I order one filter or a full Massey Ferguson 145V air-filter set?
For a full parts check, separate the service element from the safety element: buy the outer/primary service element first, then buy the inner safety element only if it is dirty, damaged or due. Do not accidentally order 7068069M1 when you meant the safety filter, or 3703704M91 when you meant the outer filter.
What is the safest way to match a Massey Ferguson 145V air filter?
Treat 3703703M91 as the hero value, not the whole truth. Serial range, engine swaps and different air-cleaner housings can beat a generic online listing.
Why can a similar-size filter still be wrong for a Massey Ferguson 145V?
Length, OD and ID together are better than one size alone. The trap is buying a filter that fits into the canister but does not seal correctly at the ends.
Would I be strict with the Massey Ferguson 145V air filter condition?
Yes. The power-to-filter-size relationship makes restriction and seal condition worth taking seriously. Replace a questionable element before heavy dusty work.
Can a cross-reference filter fit badly on a Massey Ferguson 145V?
Two cross-reference numbers give you buying options, but 3703703M91 should stay the main anchor. Confirm both replacement listings against the old filter before choosing the cheaper one. Then compare length, outside diameter and seal style before fitting.
Does engine power change how I service the Massey Ferguson 145V air filter?
With a 145 hp engine class, the horsepower is high compared with the listed element size, so restriction checks matter more. Watch for weak pull, smoke or heat under load before waiting for the full 400-hour guide.
Official information note
Mistakes do happen. Air filter specs can change by year, engine, serial range, market and air cleaner housing. Check the old filter, operator manual, parts book and official masseyferguson.com website before ordering or installing an air filter.
