This Shop Kink is one in a series of we publish for engine professionals. This Shop Kink builds on an earlier ones we published about GM industrial engine identification. These include our Shop Kink #22, GM 4.3 Industrial Engine Identification Made Easy, Shop Kink #32, GM 5.7 Litre Industrial Engine Identification Made Easy, and Shop Kink #41, Identifying the 8.1L GM Industrial Engine.

The 5.7 GM Industrial Engine recently has been adopted more and more by OEMs including generator and material handling manufacturers. Both Hyster ( a division of NACCO) and Hoist Manufacturing make forklifts that use this engine. While the 5.7 is derived from the popular small block Chevrolet engine and can look a lot like it when buried in a forklift, there are important differences. These differences are critical when it comes time to order a replacement engine. In Shop Kink #32 we gave some handy hints about how to identify exactly which GM 5.7 industrial engine you have. We indicated that you should identify the following features:

1) The stamped number on the deck on front passenger side of the engine block

2) The numer of bolt holes that hold on the intake manifold (8 vs. 12)

3) If you have the late style serpentine belt system

We now have an additonal characteristic that is important.

4) Is the front timing cover plastic or metal?

These four identifyers of the GM 5.7 engine are helpful when you call us to order an engine. To support our customers we stock both new and factory reman GM industrial engines and have them ready to ship. If you would like more info and specs on these engines, we stock GM workshop manual. Call us toll free at 800 233 6539 to order your manual. Because we always include a free Workshop Manual with every engine we ship, we will deduct the cost of the Manual from the engine price if the Manual doesn't solve your problem.
