Two numbers, one machine family, and no published rule connecting them. Rather than guess, this page carries both and explains what the evidence does and does not support.<\/p>\n

What we can state<\/h2>\n

Both numbers sit in Komatsu’s 708 hydraulic pump group, and within that group the 1x series carries pumps while the 7x series carries motors, which is consistent across every Komatsu-published item name we checked. Trade parts data attaches both to Komatsu WB-series backhoe loaders. What no source states is whether 00161 supersedes 00112, whether they are different displacements, or whether they differ by build specification.<\/p>\n

Why we publish one page for both<\/h2>\n

Two separate pages claiming the same machine would compete with each other in search and, more importantly, would each have to assert something we cannot prove. A single page with both numbers lets a buyer search either one, read the honest position, and then confirm against their own machine. That is a better outcome than a confident wrong answer.<\/p>\n

How to confirm which one you need<\/h2>\n
    \n
  1. Read the number cast on the pump you removed. It is the only authority that matters.<\/li>\n
  2. Note the machine model and serial prefix from the data plate.<\/li>\n
  3. Check the shaft spline count and length, the pilot diameter, the flange bolt pattern and the port layout against our photographs.<\/li>\n
  4. Send us the plate photograph. We quote the number your machine carries, and if we stock the other one we will say so before you pay.<\/li>\n<\/ol>\n

    Backhoe pump diagnosis<\/h2>\n

    Backhoe loaders idle a great deal and work in short, sharp cycles, which keeps oil hot and lets contamination settle rather than being filtered out. Test in this order: implement pressure and flow hot, then relief and pilot settings, then the suction line and strainer, then the pump. Our \u6cf5\u91c7\u8d2d\u4e0e\u89c4\u683c\u6307\u5357<\/a> covers the comparison method and \u5bc6\u5c01\u5957\u4ef6\u7ffb\u65b0\u68c0\u67e5\u6e05\u5355<\/a> \u6db5\u76d6\u7ffb\u4fee\u8303\u56f4\u3002.<\/p>\n
