Common Bobcat T630 Problems – Fixations & Replacements Costs Included
Whenever you face problems with your Bobcat T630, consider attending them as soon as possible. If they remain inattentive, you may end up with costly repairs.
#01. Engine Stops Suddenly During Operation – Warm up the Engine to the Required Temperature
Winter mornings can be tough, especially for vehicles. The Bobcat t630 engine stops suddenly during operation when the engine is cold. However, such a problem is less likely to happen in warmer months. Also, this can happen in the old Bobcat T630.
Don’t let the cold damage your Bobcat. So, how to solve the issue? Should you warm up your Bobcat before driving? Yes, the trick is to warm up the engine to drive comfortably and safely. Here is what you need to do.
- Step 01: Take your Bobcat T630 out in a safe place instead of a garage.
- Step 02: Turn the engine on and let it run for a minimum of 1 minute.
- Step 03: Start slowly while pressing the pedal for roughly 5-10 minutes. Avoid rushing, as the engine can get stressed before it reaches its operating temperature.
Warming up the engine can be done yourself. It doesn’t require professional help, and you can DIY without cost.
Other reasons can also play a big role in this problem. Find the below chart to learn the causes and solutions.
| Sl# | Causes | Solutions | Replacement Cost |
| 1 | Plugged fuel filter | The filter requires replacement | $40-$80 |
| 2 | Blocked fuel injectors | Fuel injectors need to be cleaned | $200 |
| 3 | Air bubbles in the fuel lines | The fuel line needs bleeding | $20-$500 |
#02. Low Oil Pressure – Refill the Crankcase with Oil up to the Required Level
Correct oil pressure is a significant parameter for any vehicle engine, and it is no exception for Bobcat T630. The moving parts of an engine get well-lubricated when the oil pressure is correct. Low oil pressure fails to lubricate the internal moving components of the engine. It can cause warping, friction, and other complications.
In this case, stopping the track loader and refilling the crankcase with oil up to the required level is mandatory. Here is the process of changing the crankcase oil.
- Step 01: Disconnect the pump.
- Step 02: Now, remove the cover of the pump.
- Step 03: Catch the oil drips with a soft and clean cloth between the crankcase drain plug.
- Step 04: Place a bucket and funnel under the drain plug of the crankcase.
- Step 05: Loosen the cap of the oil filler port. Then uninstall the crankcase drain plug.
- Step 06: Let the oil drain.
- Step 07: The Crankcase oil drain plug needs to be replaced.
- Step 08: Pour manufacturer-recommended oil through the oil filler port. Make sure to refill up to the required oil level.
- Step 09: Place the oil filler port.
- Step 10: Use a dipstick to check the oil level. Add more oil or drain excess oil if required.
- Step 11: Get a rag and wipe off spilled oil from the frame and crankcase.
- Step 12: Reconnect all the wire connections.
Refilling crankcase oil is effortless, and expert help is only sometimes necessary. However, if you are in a condition where you can’t do it yourself, take assistance from them. The crankcase oil refilling service cost is $125-$250
Some other culprits for low oil pressure are listed below, with solutions and replacement costs.
| Sl# | Causes | Solutions | Replacement Cost |
| 1 | Wrong oil viscosity or grade | Pour oil following the right viscosity rating | $125-$250 |
| 2 | Malfunctional oil pump | Replace with a new pump | $50-$150 |
#03. Engine Knocks – Adjust the Fuel Injection Pump Timing According to the Specification
Why does my Bobcat T630 engine knock? Unusual noise or knocking from the T630 engine is alarming. The problem occurs when the fuel injection pump timing needs to be balanced. Thankfully, adjusting the timing is not a big deal. You can do it yourself by following the below steps.
- Step 01: Grab a screwdriver or a socket wrench. It is required to rotate the injection pump.
- Step 02: Use a special probe or timing meter to measure the engine timing correctly.
- Step 03: Start rotating the injection pump clockwise or anticlockwise. Make sure to rotate in small increments.
- Step 04: Re-tighten the bolts after adjusting.
- Step 05: Run the engine and check whether it creates unusual noise or knocks.
Visiting a mechanic shop to adjust the injection pump timing would be best. This service will cost you anywhere between $350-$500.
The below chart shows the other reasons for engine knocks and the cost of solving them.
| Sl# | Causes | Solutions | Replacement Costs |
| 1 | Low level of engine oil | Refill the crankcase | $125-$250 |
| 2 | Low coolant temperature | Bobcat T630 engine requires warm up | DIY |
| 3 | Worn or damaged piston | Replace the piston | $75-$350 |
#04. Overheated Drive System
Plugged hydraulic oil coolers can cause an overheated drive system. Such a situation reduces the productivity and efficiency of the Bobcat T630. So, what to do to get the ultimate efficiency from your Bobcat?
Well, cleaning the cooling fins is the best solution. However, cleaning this component may be a daunting task. But in reality, this is super easy.
Read the below steps and learn how to clean the cooling fins on Bobcat T630.
- Step 01: Turn the engine off. Wait for a few minutes so that all the moving parts can stop completely and get cooled. Remove the key and engage the parking brake.
- Step 02: The cooling-shroud clean-out cover needs to be removed from the engine. Then start cleaning the cooling fins. Ensure all dust, dirt, and oil are removed from the fins. Also, keep the surfaces of the engines dust-free. Otherwise, it can cause improper cooling.
- Step 03: Reinstall the cooling-shroud clean-out cover correctly. If you run the Bobcat T630 without the cooling-shroud clean-out cover, premature damage to the engine will happen because of overheating.
On average, cleaning the fins costs $50-$100. However, if the part needs replacement, the charge can increase.
There are a few other reasons for the Bobcat T630 drive system overheating. I listed them in the chart below.
| Sl# | Causes | Solutions | Replacement Cost |
|---|---|---|---|
| 1 | Low level of hydraulic fluid | Refill the hydraulic fluid | $150-$250 |
| 2 | Stuck relief valve | Install a new relief valve | $50-$300 |

#05. Bucket Can’t Tilt – Change or Repair the Bucket taking help from a Professional
The productivity of your Bobcat T630 will be zero if the bucket can’t tilt. The bucket is one of the crucial components of the Bobcat track loaders.
The prime reason for this problem is the defective bucket control. Solving this problem requires professional help. Consult a mechanic shop and describe your problem. A professional will suggest to you the fixation process. Follow their recommendation to get the most out of your Bobcat T630.
Solving this problem is a bit complex. That is why you must take assistance from a skilled technician. The service cost will be $200-$500
#06. The battery is Not Charging – Tighten or Clean the Corroded Electrical Cable Connections
One of the biggest reasons the Bobcat T630 battery is not charging is the loose or corroded electric cable connections. Corrosion prevents the battery from receiving a full charge.
The vibration of the track loader can loosen the cable connections. Moreover, the wires can get corroded or rusted if the vehicle is too old.
Here is what you should do.
- Step 01: Locate the battery position. You can take help from the Bobcat T630 handbook. Remove the plastic cover of the battery.
- Step 02: Check whether connections are loosened. Tighten them well.
- Step 03: Get a sand-paper or wire brush to clean the connections thoroughly. Generally, the Bobcat T630 engine wire connections are thick and well-protected. So, the damage is quite impossible.
- Step 04: Once cleaned, reinstall the plastic cover.
In general, the cost of cleaning the cable connections is $30-$50. While if you decide to do it yourself, you will have to pay only $10.
The battery is not charging and the problem can also occur for the below reasons.
| Sl# | Reasons | Solutions | Replacement Costs |
|---|---|---|---|
| 1 | Damaged clamps of the battery terminals | Terminal clamps need replacement | $30-$50 |
| 2 | Battery has a bad cell | Change the battery | $45-$250 |
