SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

As is the case for the majority of the diesel products sold on Tamerx, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.

The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.

All fluids must be drained.

If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.

Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

The Komatsu PC170LC-11 SCR Outlet Catalyst Module 2013–2021, OEM 6544-01-0020, serves an important role in exhaust aftertreatment. Understanding how it works with diesel exhaust fluid (DEF) can help buyers select the correct replacement and understand its emissions-control function.

  • Supports NOx reduction: The SCR catalyst promotes chemical reactions that convert nitrogen oxides in diesel exhaust into nitrogen and water vapor.

  • Works with DEF-derived ammonia: DEF is injected upstream, where it produces the ammonia needed for the reaction at the catalyst.

  • Provides a catalytic reaction surface: Exhaust passes through the catalyst structure, allowing gases to contact the active surfaces that support NOx conversion.

  • Depends on proper operating conditions: Suitable exhaust temperatures and correct DEF delivery help the SCR catalyst perform its intended function.

  • Complements soot filtration: The SCR module handles NOx reduction, while the diesel particulate filter captures soot within the aftertreatment system.

  • Offers a specific replacement reference: Match OEM 6544-01-0020 with the existing part and confirm the equipment serial number and exhaust configuration before ordering.

TamerX Diesel Parts lists this SCR Outlet Catalyst Module for 2013–2021 Komatsu PC170LC-11 applications. Choosing the correct module and addressing any related DEF-system issues helps support proper exhaust aftertreatment operation.

A clogged SCR Outlet Catalyst Module can restrict exhaust flow and interfere with normal diesel aftertreatment system operation. Recognizing signs of internal blockage, such as excessive exhaust backpressure, reduced engine performance, and recurring emissions warnings, can help identify potential restrictions before they cause additional problems.

  • Increased exhaust backpressure: A clogged SCR Outlet Catalyst Module can restrict exhaust flow, causing pressure to rise above normal operating levels.

  • Reduced engine power: Excessive exhaust restriction may affect engine performance, resulting in sluggish acceleration or difficulty maintaining power under load.

  • Check engine light activation: Abnormal exhaust conditions or related aftertreatment problems may trigger diagnostic trouble codes and illuminate the check engine light.

  • SCR system warning messages: Exhaust restrictions or associated emissions faults may cause aftertreatment warning messages to appear on the dashboard.

  • DEF crystallization buildup: Excessive Diesel Exhaust Fluid (DEF) deposits can accumulate near the catalyst inlet and obstruct exhaust passages.

  • Abnormal exhaust temperatures: Restricted exhaust flow may contribute to unusual temperature patterns that can be identified through diagnostic monitoring.

  • Visible internal blockages: Inspection with appropriate equipment may reveal heavy deposits, damaged catalyst material, or collapsed internal passages restricting exhaust flow.

A clogged SCR Outlet Catalyst Module can cause performance issues and aftertreatment warnings, but these symptoms may also result from DPF restrictions, faulty sensors, or other exhaust system problems. Measuring exhaust backpressure, reviewing diagnostic trouble codes, and inspecting the catalyst and connected components can help confirm whether the module is clogged and determine if cleaning or replacement is necessary.

The SCR catalyst does not directly regulate fuel injection. However, severe exhaust restrictions or emissions-related operating limitations may indirectly affect engine efficiency and fuel consumption.

Frequent shutdowns may prevent the exhaust system from maintaining temperatures suitable for effective SCR operation. Repeated short operating cycles can reduce the time available for efficient NOx conversion.

Diesel Exhaust Fluid (DEF) provides the ammonia needed for SCR chemical reactions. Contaminated or improperly formulated DEF can interfere with ammonia generation, reduce catalyst efficiency, and contribute to aftertreatment deposits.

Yes. Excessive vibration can place stress on the catalyst housing, mounting brackets, and exhaust connections. Over time, this may contribute to loose components, damaged joints, or internal catalyst deterioration.
