Cross-Reference Push Rod 733817M1 – Fits Massey Ferguson

Verified fitment — Engine serial ranges checked for every Massey Ferguson, Oliver, and White model listed, so the push rod you receive matches the valve train geometry of your specific build.

Why the Same Part Number Ships to Machines That Refuse the Part

A base number alone does not guarantee fitment — the engine serial prefix determines which push rod length and tip profile your valve train actually requires.

I spent years running parts channels across Europe and Central Asia, and the most common complaint is not about quality but about fitment. A distributor once forwarded a cross-reference table that listed Push Rod 733817M1 for every Massey Ferguson 174 and 175 series machine without distinguishing between the two engine builds. [NEED_CITE: aftermarket cross-reference accuracy in agricultural engine parts] The result was a shipment that arrived on time but sat on the shelf because the push rod length differed by enough to prevent proper rocker arm engagement. Copied tables carry forward errors that only surface when the machine is already apart and waiting.

Engine Serial Matching Across Perkins-Based Diesel Variants

The Push Rod 733817M1 is specified across a wide range of Perkins-derived diesel engines — 4.212, 4.248, 6.354, and 1006.60 families — but each family has distinct valve train geometry. The tip profile that seats into the rocker arm socket, the overall length that sets valve lash range, and the lower end that rides on the tappet all vary between these engine builds. We verify every fitment request against the engine serial number, not just the machine model plate.

Variant Differences Within the Same Machine Model

A Massey Ferguson 275 could have left the factory with a 4.248 Diesel or an entirely different engine block depending on production year and market destination. Ordering by model number alone is a coin flip. [NEED_CITE: Massey Ferguson production variant differences by market and year] Our fitment process requires the engine serial — usually stamped on the block near the oil filter housing — to confirm which push rod variant the machine actually needs before anything ships.

Interface Verification at Lifter Bore and Rocker Arm Socket

The two critical contact points are the lower end sliding in the lifter bore and the upper tip engaging the rocker arm adjustment screw. Phosphate coating on the surface provides initial wear protection during the break-in period, but dimensional accuracy at both interfaces determines whether the valve opens and closes within spec. We measure overall length, tip radius, and lower-end diameter against known-good references for each engine serial group.

Dimensional and Material Specifications in Context

Forged SAE 1045 steel provides the tensile strength needed for a component that cycles through compression loads at every cam lobe pass. The quench-and-temper heat treatment ensures the rod resists bending under load while maintaining enough ductility to avoid brittle fracture if a valve train event creates shock loading. Surface phosphate coating reduces friction during the initial running hours before full oil film establishment occurs at the lifter bore interface.

What Happens When Fitment Goes Wrong

A push rod that is even slightly too long prevents the valve from fully closing, leading to compression loss and burned valve seats within a matter of operating hours. One that is too short increases valve lash beyond adjustment range, producing noise and accelerated rocker arm wear. In either case, the machine is back down and the return shipping cycle begins — costing time that the repair schedule cannot absorb.

Why Buyers Source This Push Rod Through Us

Our production lines and sourced supply both operate under one account with the same warranty terms, so there is no quality distinction between self-manufactured and partner-sourced push rods. Eight product categories mean a complete valve train job — push rods, tappets, rocker arm components, gaskets — ships as a single consignment rather than trickling in from multiple suppliers. Orders start at one piece, which matters when a single machine is down and you need one push rod, not a minimum quantity. Guangzhou warehouse stock on common items enables fast dispatch for urgent replacements. We identify the correct part from a part number, machine model, photograph, or nameplate image — whichever is available on the shop floor. Cross-reference verification covers superseded and alternate numbers so discontinued references still resolve to the correct current component.

Documentation & Verification

• Commercial invoice lists Push Rod 733817M1 with engine serial fitment notes
• Cross-reference sheet marks 733817M1 as reference only alongside verified alternates
• Dimensional inspection record covers length, tip radius, and bore diameter
• Warranty terms cover manufacturing defects for 3 to 12 months
• Packing photographs show individual protective wrapping before carton sealing
• HS code and customs documentation provided for international clearance

Fitment Check Before Installation

• Measure overall length and compare against the old push rod before fitting
• Verify the upper tip seats fully into the rocker arm adjustment screw socket
• Confirm the lower end slides freely in the lifter bore without lateral play
• Check valve lash adjustment range after installation to ensure proper engagement
• If dimensions do not match, halt installation and contact us with photos for resolution

Request a Fitment Confirmation Before You Commit

Send us the machine model, engine serial number, or a photograph of the existing push rod with a ruler alongside it. We will cross-reference the part against our verified fitment database and confirm whether 733817M1 matches your specific engine build — or identify the correct alternative if it does not.

Frequently Asked Questions

Q: How do I confirm this push rod fits my specific machine and engine serial? A: Provide the engine serial number — typically found on the block near the oil filter housing or on the engine data plate. We cross-check it against our verified fitment list for the 4.212, 4.248, 6.354, and 1006.60 engine families to confirm the correct push rod variant before any order is processed.

Q: My old part has a different number — can it still be replaced by 733817M1? A: Superseded and alternate numbers are common across Massey Ferguson, Oliver, and White equipment. Send us the number on your existing push rod along with the engine serial, and we will verify whether 733817M1 (reference only) is the correct cross-reference match or if a different variant is required.

Q: Why do the same machine models appear with different engine serial requirements? A: Manufacturers used different engine builds for the same tractor or combine model depending on production year, market, and emission requirements. A Massey Ferguson 275 with a 4.248 Diesel needs a different push rod than one fitted with an alternate block, so engine serial verification is essential.

Q: Can I order a sample to verify fitment before placing a larger order? A: Yes. We supply sample units so you can physically check the fit at the lifter bore and rocker arm socket before committing to a bulk order. This is especially useful when replacing a discontinued number or fitting machines where the nameplate is no longer legible.
