Kubota B3350 Regeneration Problems and DIY Solutions

1. Excessive Exhaust Smoke:

If you’re noticing billowing exhaust smoke during regeneration, don’t panic. This can be due to incomplete combustion of soot in the diesel particulate filter (DPF).

A DIY solution is to rev up the engine to a higher RPM during regeneration, helping achieve the necessary temperature for complete combustion.

Hiring a Professional/Garage:

If the smoke persists, it’s best to consult a professional. They can perform a thorough check and ensure that the DPF system is functioning as it should. The cost for this could vary but typically falls between $150 to $300, depending on your location and the extent of the issue.

2. Frequent Regenerations:

If your B3350 seems to be initiating regeneration too often, it might be a result of short trips that prevent the engine from reaching the necessary temperature.

Try to incorporate longer periods of operation. Regularly engaging in longer tasks can help maintain the optimal temperature for regeneration.

Hiring a Professional/Garage:

If this problem persists even after adjusting your operation patterns, it’s time to bring in a professional. They can inspect the sensors and diagnose any issues that might be affecting the regeneration cycle. Costs might vary, but budget around $100 to $200 for a thorough diagnosis.

3. Loss of Power:

If you’re experiencing a noticeable drop in power during regeneration, it could be due to the engine diverting energy towards the regeneration process.

One way to tackle this is to schedule your tasks strategically, avoiding situations where you need maximum power during regeneration.

Hiring a Professional/Garage:

If power loss becomes severe or persists outside of regeneration cycles, it’s time to consult a professional.

They can assess the engine’s performance and address any underlying problems. Costs might range from $200 to $400 depending on the repairs required.

Frequently Asked Questions:

Q1: How often does the Kubota B3350 need to undergo regeneration?

A: The frequency of regeneration depends on factors like operating conditions and fuel quality. On average, it’s recommended to see the regeneration process every 20 to 30 hours of operation.

Q2: Can I manually initiate regeneration on my Kubota B3350?

A: Yes, you can. Some models allow manual regeneration initiation, which can be handy if you notice the need for regeneration before the automatic process kicks in.

Q3: Are there any additives I can use to prevent regeneration issues?

A: While there are additives claiming to aid regeneration, it’s best to follow the manufacturer’s recommendations regarding fuel and maintenance to ensure proper functioning.
