Massey Ferguson 133 Super Air Filter FAQs
What should I buy for a full Massey Ferguson 133 Super air-filter service?
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 1026131M1 when you meant the safety filter, or 3703704M91 when you meant the outer filter.
How do I avoid buying the wrong Massey Ferguson 133 Super air filter?
Do not buy from the title alone. Match 7068311M91 against the removed filter, then check gasket shape, end-cap depth and cover fit before starting the tractor.
How can part-number style help check a Massey Ferguson 133 Super filter?
The primary number format is a Massey-style M-suffix number, while the page also has separate companion numbers. That is exactly where copy-paste ordering mistakes happen.
How do I avoid mixing up Massey Ferguson 133 Super outer and safety filters?
This looks like a multi-element setup. Keep the outer/primary service element and the inner safety element separate when ordering, because mixing up 1026131M1 and 3703704M91 is the easy mistake.
Can a dirty air filter affect Massey Ferguson 133 Super performance?
This sits in the utility range. The 300-hour guide is useful for planning, but dusty work should shorten the inspection cycle.
Can a Massey Ferguson 133 Super engine swap change the air filter?
If the tractor has had an engine swap, ignore generic model-name fitment until you compare the housing and old element.
What is the point of the Massey Ferguson 133 Super inner safety air filter?
On a a primary, outer and inner safety element setup, the inner element is the last barrier. If you remove it casually in a dusty shed, you defeat the reason it exists.
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.
