The updated oil cooler and oil filter bypass spring (on the left, compared to original spring) is used in all JASPER remanufactured 3116 Electronic, 3126 Electronic and C7 Caterpillar engines, regardless of their original production date.

Jasper Engines & Transmissions has taken a parts upgrade that Caterpillar has made to select engines produced after a certain date and we have expanded and implemented the upgrade to include a broader range of remanufactured products.

JASPER includes a later-than-original style oil cooler and oil filter bypass spring, on all 3116 Electronic, all 3126 Electronic and all C7 JASPER Remanufactured Caterpillar engines.

“The primary reason for this upgrade is to maintain cleaner oil in the system by allowing less oil to bypass the filter during cold starting conditions,” says Fred Ernst, JASPER Diesel Marketing Manager. “This in turn forces more oil through the filter during that time. It also allows more oil flow through the cooler, resulting in maintaining cooler oil temperatures during normal engine operation.”

Where Caterpillar implemented the improvement on engines built after a certain date, JASPER makes the upgrade on any of the above-mentioned engines, regardless of their original production date.

“It’s another value added to our diesel product line in an effort to improve quality at no extra cost to the customer,” added Ernst.
