Steve (BC) 10-25-2009 10:17:29 154.11.37.47 738281 Report to Moderator	Got the hydraulic pump & center housing cleaned out of several inches of sludge & on my 1952 8N. The PO said that this tractor sat more than it was run. The fluid was a light creamy color indicating water in the system. Most of the internals have a slight coating of corrosion. I'm impressed that the hydraulics worked well on this tractor & the pump did not freeze and crack. Since the transmission case shares the same fluid with the hydraulic system & rear axle would it be good practice to clean out the base of the transmission case? I would imagine access to the bottom of the transmission case is limited. And the only access would be from the top under the gear shift cover or from the bottom drain hole? Any advice or experience is greatly appreciated. Thanks, Steve [Reply]   [No Email]

Its much the same for the hydraulic pump,,, spray wipe and go if you must but don't go dig'n,,, if you must dig then drop the pump. 60 years of dirt accumulation is a beach to clean out even with the tractor disassembled,,, a once in a life time experience everyone should enjoy   [Reply]   [No Email]

Today I got the rear diff, the hydraulic pump & the center housing squeaky clean. Got'ta love that thick sludgy mess! Sure wish I was smart enough to go the pressure washer route but the end result was satisfying. As well the hydraulic lift needed some attention. I replaced the cork friction disk on the quadrant control. This took time as the aluminum friction plate was stuck to the control lever shaft. Using penetrating oil, heat, & shims - a couple of sturdy wacks loosened the bond. I then replaced the cam follower pin which was 2/3's worn & scraped the old gasket material off the case (this stuff was stuck on there really well). I checked the bottom of the transmission thru the drain hole - there is lots of sludge in there. I will clean this out sometime this week. I have never taken the gear shift cover off an N series before. What should I look out for? The parts manual shows a spring & detent ball at the rear of the top cover, probably need to be careful around this? Thanks again for the replies & advice, Steve   [Reply]   [No Email]

What I done was took the top cover off , checked linkage , cylinder etc, sprayed everything with a garden sprayer with diesel fuel , blew all the crap out with air in the cover. When the top is off it is easy to spray the rest of the pump and the sludge below the pump , drained everthing through the pump drain , redid the spraying with the same oil & diesel 2 more times , wouldn't have believed how clean it came. Put in new fresh oil , works terrific. Good luck. Stan 1949 8N146710 1949 8N179555 1949 8N197904 1950 8N254079 1951 8N362039 & a 1950 parts tractor In a pear tree   [Reply]   [Send Email]

Let it drain out the plug in the bottom. We also pull the top cover and PW the rear end. Use compressed air to blow it out good. Serve milk and cookies afterwards. ie. You can eat off of it. Spray it all down with Water Dry 40 then let it sit open for a day to dry out. Works good.   [Reply]   [No Email]

Surprizinly enuff, neither the tranny nor the diffy collects much gunk 'cuz all them spinnin' gears and stuff keeps their housings pretty well "flushed" and so all the "gunk" settles in the hydro-pump housing which doesn't have spinnin parts. My advice, donnna worry 'bout the tranny or diffy ......Dell   [Reply]   [Send Email]

Removal of the PTO shaft and transmission top cover will provide adequate access to both cases for use of a garden sprayer and gasoline. Dean   [Reply]   [No Email]

I use a sprayer with a 50/50 mix of kerosene and gas to wash all the junk out. Just make certain that all the wash mix is evaporated before refilling. Put a new shifter boot on also as thats where water gets in.   [Reply]   [Send Email]
