We can also bore and sleeve large compressor cylinders up to 20 inches in diameter, 30- inches long. Counterbore inserts and lower receiver sleeves are installed withi .0001-inch accuracy. With this capacity, we can easily handle blocks as large as the 3516 Caterpillar, 7042 Waukesha and 8G825 White Superior.
