Solutions to Bobcat e42 excavator problems
The problems occurred in different parts of the Bobcat e42, decreasing the power output. Thankfully, diagnosing the problems and solving them is super easy.
In this section, you will learn the details of the problems and solutions.
#01- Leak in the Hydraulic System: Replace the Leaky Hydraulic Part
This complex problem requires detailed knowledge about the Bobcat e42 to solve manually. The problem arises from the crown seal and blocks the hydraulics until it leaks into the system.
Due to the leaks, hydraulic fluid fails to pass through the system. As a result, the Bobcat e42 starts losing efficiency. In addition, the extendable arms stop moving. Follow the below steps to identify the leaks.
- Step 01: Look for any flat spots where the crown seal is positioned.
- Step 02: Silicone or plastic creates the spot, and is necessary to rub it.
- Step 03: Carefully check the fluid puddles underneath your mini excavator.
- Step 04: After discovering the leak around the crown seal, the swivel joint needs repair. You can do this with the help of plastic nylon spacers.
- Step 05: Once the damaged part of the hydraulic is replaced, inspect the whole system intently for other leaks.
I recommend taking your Bobcat e42 to an expert when this error occurs. Bear in mind that solving this problem will cost you between $500 – $2500 based on the leak level.
#02- Ball Bearing Failure : Regular Maintenance is a Must
The ball bearing is a part of Bobcat e42’s main bearing. So, when a problem appears in the ball bearing, you must promptly act without being late. The reason is, if you are less careful, the main bearing can damage permanently.
The best solution to this problem is regular maintenance. Such acts will surely minimize the complication.
Here is what you need to do.
- Step 01: the correct way to identify the problem is if any part of your mini excavator is having trouble moving properly.
- Step 02: Turn the engine for at least 1 or 2 hours.
- Step 03: Inspect the main seal of the Bobcat e42 for the leak of bearing fluid.
- Step 04: Filling the bearing is mandatory if you find the slightest fluid leak.
- Step 05: In case the level of damage is unrepairable, consider replacing the final drive.
This problem is damn dangerous. Your Bobcat e42 may break down lastingly due to excessive stress. The replacement cost is high. You must spend roughly $1,700 for a Dx340 Slewing Bearing Ring. Also, the labor cost will be almost $3,000.
#03- Leakage in the Gear Oil : Repair & Refill Oil
The oil and coolant capacity of Bobcat e42 is 6.3 liters and 8 liters, respectively. Gear oil leakage happens to external damage to the oil filter.
Generally, Bobcat E42 oil requires a change every few months. Otherwise, oil leakage frequently appears if you don’t maintain the intervals. Learning about the leakage is super easy. When you experience high oil consumption, be sure there is a leakage in the oil filter.
The below steps describe how to fix leakage in the oil filter.
- Step 01: First, look at the Bobcat e42 oil meter. Is the meter showing less oil in the filter? For a positive answer, fill the filter up with a little oil.
- Step 02: Intently diagnose the mini excavator’s lower part to identify the oil leakage.
- Step 03: How many leaks are there? For 1 or 2 leaks, the repair is the best solution. You can use industry-grade tape to repair them. On the other hand, in case you find equivalent to 3 or more leaks, replacement of the whole oil filter system is the only solution.
- Step 04: Lastly, drain the oil completely from the fluid container. Then refill it with manufacturer-recommended or premium-quality oil.
The fixation process needs expertise and patience. So, calling an expert will be best. Fixing oil leakage will cost you $300. The cost includes the expert fee. You will have to spend around $1100 to replace the whole oil system.
Wrapping Up
Despite a few Bobcat e42 problems, this mini excavator has an excellent safety feature. Its engine uses diesel. For this reason, if the engine catches fire, it won’t spread to the driver’s seat. This means it is pretty safe from fire hazards.
