5 Solutions For Bobcat 751 Problems

We have stated that some problems with the Bobcat 751 are minor and have simple fixes, which can be resolved using a do-it-yourself strategy. On the other hand, some issues, such as the defective steering and solenoid issue, are considered major problems and demand that you call a professional.

Anyway, we’ve listed some of the most effective fixes for some Bobcat 751 issues here. Go ahead, give it a try.

1. Start-Up Issue: Check And Repair

Start-Up Issue Check And Repair

Start-up issues may involve one or more engine components, ranging from the ignition coil to the Lucas pump. You may need to check a number of components before identifying the source of the issue. You might have to do the following checkup before finding the main culprit behind the start up issue.

  • Check if the belt is loose and tighten properly.
  • Inspect the ignition coil for signs of damage and replace it.
  • Put sufficient fuel into the machine and inspect if the injector line has any leaks.
  • The Lucas pump on the bobcat 751 engine might require replacing.
  • Check if the battery performs enough revolutions for the machine to operate normally.

The process of identifying and fixing this problem takes a lot of time and patience. When it comes to fixing the start up issue, it actually depends on the severity and the cost of the replacement parts.

2. Fuel Pump Problem: Repairs And Replacements

Fuel Pump Problem Repairs And Replacements

This is yet another significant issue that you might experience. Fuel is like blood, and the pump is like the engine’s beating heart. A properly working pump distributes oil to the various engine components. On the other hand, Faulty pumps create an imbalance in the Bobcat 751.

You will experience a drastic drop in the efficiency of your machine, which includes not being able to take the regular load and sudden pauses. There can be many reasons behind the failure of the pump. Here is a to-do list to find the main reason behind the issue and fix it accordingly.

  • Check the fuel filter for dirt or damage and clean or replace accordingly.
  • Check if the primer balls are working right and pump them properly.
  • Look thoroughly for air leaks and repair the fuel line if found any.
  • Next, check if the lift pump is in working shape and replace it if it’s not working.
  • Manually pump some fuel into the injector to check if it’s working. Thoroughly clean if dirty or replace it if damaged.

So these are the issues and some common fixes you can follow. When it comes to fixing the fuel pump, it costs more if you have to replace anything; if you are lucky, simply cleaning will solve the issue.

3. Faulty Steering: Add transmission Fluid, Replace parts or

Steering issues include the wheel sticks when it is turned left or right. You should check the hydraulic system. Also, the tank must have the required amount of fluid. Lack of fluid is another reason for the steering failure. When the symptoms of the steering issue come out, you can try one of the following:

  • Check if there is any issue with the steering motor. You might have to replace the steering motor
  • You might have to bleed the air from the system or replace the hydraulic pump and filter
  • Try replacing all old hydraulic hoses to remove any clogged or damaged hoses.
  • Make sure all the electrical connections are tightened

Hopefully, one of the reasons mentioned above is the culprit behind the Bobcat steering issue, and you will successfully come up with a solution in no time.

4. Loose Belt: Tighten The Belt

Loose Belt Tighten The Belt

A common problem in almost all the construction equipment class machines is the loose belt. This loose belt will hamper efficiency while operating your machine.

The bobcat 751 loader will output low power and movement when affected by this problem. Follow the methods below to tighten the drive belt in no time.

  • Locate the drive belt and disconnect the battery connections with a socket wrench while wearing rubber gloves.
  • Next, you have to lose the bolts that are responsible for attaching the bracket to the alternator.
  • Take a non-conductive stick and pry it into the belt, remember to keep your pressure on the belt with the stick.
  • Carefully take the alternator belt, put it in a new position, and tighten back the bolts.
  • Once the alternator belt has been put in a new place and tightened, use tension testers to check.
  • Reconnect the battery connections back to the belt and close the lid.

The problem can be fixed in a lot of ways but this is the simplest one by far. This problem doesn’t require any additional costs unless you hire. If you decide on fixing it yourself, remember to wear non-conductive gloves and goggles for safety.

5. Fuel Solenoid Failure: Check Linkage, and Voltage

Fuel Solenoid Failure Check Linkage, and Voltage

The most common reasons for the failure of the Bobcat fuel solenoid include low voltage, improper linkage, and a damaged solenoid. Here are some of the common solutions that you can try.

  • To solve the solenoid problem due to voltage issues, check several connection points using a multimeter and find out the damaged section and solve the issue.
  • If the issue is the linkage, the solenoid cannot draw power. What you can do is run a wire from the solenoid to the battery; if the faulty solenoid works, then most probably, this is a linkage problem.

The cost of fixing depends on the severity. The mechanic will charge for the diagnosis and repair. You have to bear the replacement cost. On average, a bobcat 751 fuel solenoid costs $40 to $60.
