Been messing with a 170 off and on this summer, after replacing foot clutch, fuel tank and having manifold machined, radiator repaired (because of previous owners mistakes), loosening up hydraulic linkages and TB spool, removing 2 1/2 pails of of calcium chloride out of each rear tire, replacing tire valves, going through the electricals so everything works, I took it to the field for it's first run in years... warmed up, I pulled engine and both hydraulics and transmission plugs. Also removed full flow filters and cut them open and eventually removed the metal screen at the hyd. sump. Here are a couple pics of what I found... A set of numbers I found above hydraulic sump on left side... Do other 170's have a number here or is this a build date?  FF filters engine and hydraulic. Look at engine filter, got metal in the pleats and definate metal where I laid it down to drain. ... right filter is hydraulic, crushed in and can bottom extended from freezing.  Guess I will be dropping the pan to check rods and mains to see where the metal is coming from. Here is the screen from the sump, must have really been plugged at one time. Notice the rip.  Screen now soldered. Wonder how much a new one costs?  And the sump had what looks like heavy mud at the bottom. no picture... yet. And I thought a change of oil and the old 170 would be put back to work. What was I thinking for tractor that has 9000 hours on the tach. Well it doesn't jump out of gear, and the two speed works good and one brake works... and the hydraulic seems to work strong despite of what I found. ------------- He who says there is no evil has already deceived himself The truth is the truth, sugar coated or not.

| I bought the fine mesh sump screen for my 220 over 30yrs ago and it was $200 then |

Steve M., YIKES! Probably double that now if not NLA. DSeries4... Okay, I went out and checked our old 170 and that one has no numbers above the sump... so then it really makes me wonder what the 70 16 82 means. I wouldn't think they did it just for fun.  or maybe they did.  ... but they are definitely stamped in there.------------- He who says there is no evil has already deceived himself The truth is the truth, sugar coated or not.
