1S2895 Valve Insert for Caterpillar

1S2895 is a standard exhaust valve insert for Caterpillar equipment. The part is used with Caterpillar wheel-type loaders, wheeled tractor-scrapers, truck engines, and ship equipment in the models and series listed below. It is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The product is identified as a valve insert for the exhaust side. The available application data specifies Caterpillar equipment by machine type and model designation; no additional machine serial-number ranges or engine configuration details are provided. Fitment should therefore be checked against the equipment model and the installed part number before installation.

Fitment

• Wheel-type loader: Caterpillar 980
• Wheeled tractor-scraper: Caterpillar 621
• Wheeled tractor-scraper: Caterpillar 623
• Truck engine: Caterpillar 1674
• Truck engine: Caterpillar 1676
• Ship equipment: Caterpillar D334
• Ship equipment: Caterpillar D336

The listed applications cover several Caterpillar equipment categories rather than one machine type. Caterpillar 980 is identified as a wheel-type loader application. Caterpillar 621 and 623 are identified as wheeled tractor-scraper applications. Caterpillar 1674 and 1676 are identified as truck-engine applications, while Caterpillar D334 and D336 are identified as ship-equipment applications.

The fitment information names the model designations but does not specify production years, serial-number prefixes, engine arrangement numbers, or installation quantities. These details are not included in the available product data and should not be inferred from the model name alone.
