Why Oil Filter Replacement Matters

An oil filter removes metal particles, dirt and soot from engine oil before it circulates through the engine. A clogged or worn filter can reduce oil flow, raise wear on bearings and shorten engine life. Regular replacement keeps the oil clean and helps avoid costly repairs, especially on older high-mileage engines that run long hours.

Why Choose IXIN’s LF3620 Lube Filter

  • Factory-Direct Supply: IXIN manufactures filters in its own factory in Linxi County, Hebei. You deal with the manufacturer, not a trading company.
  • Wide Cross-Brand Coverage: One LF3620 lube filter replaces Fleetguard, Detroit Diesel, Baldwin, Donaldson and WIX references, which helps distributors simplify inventory.
  • Long-Running Engine Family: The Detroit Series 60 is still widely used in trucks, buses and generator sets, so this is a steady repeat-order item.
  • Customization Available: We support customization of filter paper quality, metal thickness and packaging for your market.
  • Fast Delivery: In-stock items usually ship in 5 to 10 days. Made-to-order items take 15 to 45 days, depending on quantity.

Application Notes

Before ordering the LF3620 lube filter, check these points:

  1. Compare the number on your existing filter with the cross reference table above.
  2. Check how many filters your engine uses, since many Series 60 engines use two.
  3. Confirm the thread is 1 5/8-12 UNS-2B and matches your filter head.
  4. Measure the height and outside diameter of the old filter, and check the gasket size.

If you are not sure about fit, send us the OE number or a photo of the old filter, and we will help you confirm.

Installation and Maintenance Notes

  1. Warm up the engine slightly, then switch it off and let it cool to a safe temperature.
  2. Place a drain pan under the filters, and remove the old filters with a suitable filter wrench.
  3. Check that the old gaskets came off with the filters. A leftover gasket can cause leaks.
  4. Clean the mounting surfaces, and lightly oil the gaskets of the new LF3620 lube filters.
  5. Spin the new filters on by hand until the gaskets touch, then tighten as specified by the engine manufacturer.
  6. Refill oil to the correct level, start the engine, and check for leaks.
  7. Replace the filters at the interval recommended by the engine maker, and sooner in severe conditions.
