Found this site when searching for Ingersoll parts. Having a hard time finding parts for 1989 Ingersoll 6018. Tractor has front end loader and backhoe, both worked great, but tractor moved very slow in forward/reverse. Pulled pump and determined that main pump section (tandem pump) has cracked wear plate. Believe I need ING-C32955 kit to repair, or a replacement pump. Here's a pic of my pump before break down.
