Picture says a thousand words. I have rebuilt many excavator pumps Komatsu, Kawasaki, and Cat to name a few. Without pictures it would not have been very fun. Especially when you have two or thee of them in pieces at a time. Another helpful hint is to get a chunk of phone wire from you handy tellie repairman. You know the big bundled stuff with a bazillion colors. All you need is a piece about six inches long. Pull out one wire cut it in two and you have two color coded twist ties to mark connecting points of hoses or wire bundles.
