Review: Je suggère cette article - Très bon produit Review: Quality shows - If you’re worried about your RV parts failing while you’re out in the boondocks, just buy OEM quality parts. I’ve seen reviews where people have bought cheaper parts and had them fail after a few hours. Quality matters. Sure, some people say it’s just an oil filter and an air filter. But this is an air and oil cooled generator. The environments we are in dusty and dirty as well. Clean oil and clean air mean a longer lasting gennie. ## Features - Product Type:Oil Filter - Item Package Weight:0.27 Kilograms - Item Package Dimension:8.1 cm L X9.3 cm W X9.4 cm H - Country Of Origin: United States ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003ZOIYZ6 | | Automotive Fit Type | Vehicle Specific Fit | | Brand | Cummins | | Brand Name | Cummins | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.7 out of 5 stars 667 Reviews | | Global Trade Identification Number | 00690781000230 | | Item Dimensions | 8.9 x 8.3 x 8.3 centimeters | | Item Weight | 0.01 Ounces | | Item dimensions L x W x H | 8.9 x 8.3 x 8.3 centimeters | | Manufacturer | Cummins | | Manufacturer Part Number | 122-0645 | | Material | Synthetic material or paper | | Material Type | Synthetic material or paper | | Model Number | 122-0645 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | 1220645 | | Part Interchange Info | Compatible with Emerald Green and Marquis. | | Product Grade | Replacement Part | | Product grade | Replacement Part | | Thread Size | 3/4-16 UNC | | Thread size | 3/4-16 UNC | | UPC | 690781000230 | | Unit Count | 1 Count | | Vehicle service type | Car | ## Product Details - **Brand:** Cummins - **Item dimensions L x W x H:** 8.9 x 8.3 x 8.3 centimeters - **Material:** Synthetic material or paper - **Product grade:** Replacement Part - **Vehicle service type:** Car ## Images ![Onan 122-0645 Oil Filter - Image 1](https://m.media-amazon.com/images/I/81C0EQ9C2KL.jpg) ## Questions & Answers **Q: Is this for a 1996 mh with onan marquis 5000?** A: Not sure but it fits a 2001 Onan Emerald 4000 **Q: does this cross reference to A054X497?** A: Not familiar with number you're trying to cross reference to. When I ordered the Cummins filter to fit my Onan LX790 20hp engine, the box had a label attached referencing to the 1220645 oil filter. The filter I received had different dimensions and the gasket was much narrower than the one's I previously purchased. Through some research I found that the FRAM PH3614 oil filter was a great substitute. I've ran my tractor since last November and the oil is still clean and transparent on the dipstick. When I used the Cummins Filters the oil would have been very dirty and dark on the dipstick by now. I feel the FRAM is a much better choice if it will fit your application. **Q: Does this fit the Onan E140h motors?** A: Probably but not absolutely sure **Q: Will fit wheel horse 416h** A: IDK but the one you need for that machine is 83-283 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Je suggère cette article *by C***S on 30 April 2026* Très bon produit ### ⭐⭐⭐⭐⭐ Quality shows *by M***H on 19 May 2024* If you’re worried about your RV parts failing while you’re out in the boondocks, just buy OEM quality parts.
