Replacing parts on a Mahindra tractor can be expensive, especially when it comes to Tractor Engine Parts, but at Reubicon Tractor Parts, we offer a huge selection of high-quality, affordable Aftermarket Mahindra Tractor Parts. Our durable, reliable parts make it easy to keep your tractor in great shape without breaking the bank.

Here’s a spotlight on some of our most commonly purchased aftermarket Mahindra Tractor Engine Parts.

Tractor Crankshafts

The crankshaft is a core engine component that converts combustion energy into usable mechanical motion. Because tractors operate under sustained load and torque, the crankshaft condition is critical to both performance and engine longevity.

Here are some signs that indicate that your crankshaft may need replacement.

1. Persistent Engine Knocking

2. Low or Fluctuating Oil Pressure

Excessive bearing clearance around the crankshaft reduces oil pressure and this may trigger warning lights or gauge fluctuations.

3. Excessive Engine Vibration

Bent or cracked crankshafts throw off engine balance and vibrations may increase with RPM or heavy loads.

4. Metal Shavings in Engine Oil

This is a strong indicator of internal wear or scoring, and this issue often is discovered during oil changes or filter inspections.

5. Hard Starting or Sudden Engine Seizure

Severe crankshaft damage can prevent the engine from rotating freely. In extreme cases, the engine may lock up entirely

6. Abnormal Crankshaft End Movement

Excessive forward/backward movement indicates thrust bearing wear or crank wear. This issue is common with heavily worked tractors.

Crankshaft Repair Vs. Replacement

In some cases, a crankshaft can be repaired. If the wear is minimal and the journals remain within tolerance, you might be able to reground or polish the crankshaft and extend its life. However, if the crankshaft is bent, cracked, heavily scored, or out of specification, it is time to replace this part.

Additionally, when the crankshaft is damaged, you may also notice damage to the bearings, oil pump, or engine block. If this is the case, you need to purchase a new crankshaft as well as new bearings and likely a new oil pump.

The block may still be usable if the bearing saddles are intact and the line bore measurements remain within tolerance. In addition to crankshafts, we sell affordable bearings and oil pumps in our aftermarket Mahindra Parts Catalog Online.

Tractor Turbochargers

Turbochargers use exhaust gas energy to force air into the tractor engine’s combustion chamber. This increases engine power and torque, improves fuel efficiency, and enhances performance at lower RPMs.  

Turbochargers break down over time, especially when tractors are used in dusty, hot conditions or when tractors often carry heavy loads. Here are a few signs that indicate issues with this engine part.

Regular oil changes and oil filter changes can help prevent damage to the turbocharger, and we offer affordable aftermarket Mahindra Oil Filters on our website. An oil and filter change, combined with swapping out hoses and clamps when you see signs of wear, can ensure that your turbocharger stays in good shape for as long as possible.

1. Loss of Power or Poor Acceleration

If your Mahindra tractor feels sluggish or struggles under load, and you notice reduced PTO performance, these issues can be caused by worn turbo bearings or damaged compressor blades.

You may be able to swap out bearings, but if the blades are damaged, a full turbocharger replacement is usually your best bet.

2. Excessive Exhaust Smoke

It is always a good idea to keep an eye on exhaust smoke. Different colors indicate specific problems, including:
Blue Smoke: oil leaking past turbo seals
Black Smoke: insufficient airflow due to turbo inefficiency
White Smoke: incomplete combustion (can be turbo-related)

3. Whining, Grinding, or Siren-Like Noises

High-pitched whining or metal-on-metal sounds can indicate bearing wear or contact between the turbine wheel and housing.

4. Oil Leaks

If oil is visible at the turbo inlet/outlet or in intercooler piping this often is a sign of failed turbo seals or excessive shaft play.

5. Increased Oil Consumption

Even if you don't see any obvious external leaks, increased oil consumption can indicate turbocharger issues.

6. Excessive Turbo Shaft Play

Turbo shaft play refers to the amount of movement in the shaft that connects the turbocharger’s turbine wheel (exhaust side) to the compressor wheel (intake side). This shaft spins at extremely high speeds—often 100,000 RPM or more—and is supported by a thin film of pressurized engine oil.

During an inspection, if you notice any significant radial or axial movement, this can indicate internal wear. Again, frequent oil changes and oil filter changes, and using high-quality oil often can prevent this issue and prolong your turbocharger's life. However, if you need a new turbocharger, we have affordable options for most Mahindra models.

Tractor Cylinder Heads

Cylinder heads seal the top of the cylinders and help manage airflow, combustion, and heat. Because tractors operate under sustained load, cylinder head condition has a direct impact on power, efficiency, and engine life. Here are some signs that indicate that the cylinder head might need replacement.

1. An Overheating Engine

If you have persistent and unexplained overheating, this could be caused by cracked cylinder heads, warped surfaces, or restricted coolant passages.

2. Coolant Loss With No Visible Leak

In some cases, coolant may be entering the combustion chamber, and this can indicate a cracked head or a failing head gasket.

3. White Exhaust Smoke or Steam

Coolant burning in the cylinders produces white smoke, and this is typically more noticeable at startup or under load.

4. Oil & Coolant Mixing

If you notice milky or frothy oil on the dipstick or oil cap, this is a serious indicator of internal sealing failure.

5. Loss of Power or Rough Operation

You may notice poor compression due to valve, head, or gasket issues. The tractor may misfire, idle roughly, or struggle under a load.

6. Hard Starting

Compression loss or coolant intrusion can make cold starts difficult. This is more common in diesel engines with head or valve damage.

7. Bubbles in Radiator or Overflow Tank

This is caused by combustion gases leaking into the cooling system, and it is a classic sign of head or head gasket failure.

8. Visible Cracks or Warping (During Inspection)

Cracks often form between valves or injector ports. Warping prevents proper gasket sealing, even if the head looks intact.

In some cases, you may be able to simply replace valve seals or guides, and even warped cylinder heads might be resurfaced if they are within tolerances. If the heads are cracked or you are experiencing severe overheating, you likely need to replace the head and the gasket. In many cases, opting for a new aftermarket cylinder head delivers better long-term reliability than attempting repairs.

Tractor Condensers

The condenser is part of your tractor’s air conditioning system. As with all air conditioners, its job is to remove heat from the refrigerant so the system can produce cool air inside your cab. If not working properly, you may notice the following signs.

1. Weak or No Cold Air From Cab Vents

This is a common early symptom. The A/C may blow air, but it is not cold. This could indicate that the condenser needs to be cleaned or may need to be replaced.

2. High A/C System Pressure

Restricted airflow or internal blockage causes pressure buildup, and this may trigger safety shutoffs or compressor strain.

3. Visible Damage or Bent Fins

Rocks, debris, or pressure washing can damage fins. Bent fins restrict airflow and reduce heat transfer.

4. Refrigerant Leaks

If you notice oily residue on or near the condenser, this can indicate that replacement may be needed. Small pinhole leaks are common from corrosion or vibration.

5. Frequent Compressor Failure

If you notice repeated compressor issues, these often point to condenser problems, as a failing condenser can overwork the compressor.

6. Overheating at Idle or Low Speed

When the tractor is idling or moving slowly, there may not be enough airflow across the condenser to remove heat effectively. As engine speed increases, airflow improves, and cooling may temporarily return.

7. Excessive Dirt, Chaff, or Dust Buildup

Debris can block airflow, and even a functioning condenser cannot work if airflow is restricted. To prevent this specific issue, we recommend regularly inspecting and cleaning the condenser, especially in dusty conditions.
