PT425 50 Hour Hydraulic Filter Change

MossRoad · Sep 29, 2004

On our 425 it is just a cap nut that is easily removed. The hose is just a piece of tubing with one fitting on one end. The fitting just threads on with my fingers. I barely snug it with an open end wrench. I don't even know if that is necessary, as there is no pressure on it when bleeding into the tank. It goes on rather easily. Sorry to hear of your troubles. /forums/images/graemlins/crazy.gif

Many thanks for the reinsertion of your 2002 post , re: 50 Hour Hydraulic Filter Change. "Play Thing" ( my wife's name for the PT422 ) finally reached 50 years, sorry hours. Luckily I copied it again, having misplaced the original copy, and therefore was able to follow all the steps. However, upon reaching the laying of the paper towels in the base, I added another step.
[My once bragged about 'educated ' fingers, in their octogenarian state, need to be constantly challenged, they were and seem to be working fine ]
After breaking the filter loose, I was able to uinscrew the filter while holding a 1 gallon Zip Lock Bag around the filter. Turned out pretty good , even though I still had to balance the new filled filter, the paper towel was good for other uses .
I know you will enjoy trying this one. Thanks for a wonderful sequence of operation, that made my experiment so much easier.

Hey, that sounds like a very good idea. The last time I did it I found that a small Glad Ware dish worked pretty good. But I bet a bag will work better. I'll try it next time. Thanks! /forums/images/graemlins/laugh.gif

I tried this method only using a small wal-mart plastic bag. Best idea since the weedeater. Try it you all. You will LIKE IT!! Thanks to NJBill

" I still had to balance the new filled filter "

The owner's manual for the Kohler engine in my PT-425 also requires that the replacement oil filter be filled with fresh oil and then screwed onto the engine. But the filter mounts horizontally!! Guess I'll have to push the PT over on its side, crawl underneath, and screw on the filter filled with oil!!!

Another example that even the inspired words of manufacturer's reps and owner's manuals are not gospel!!

I heard that 14! I guess you have to fill yours with oil after you install the filter. How long do you have to crank the engine to prime that filter?

Just like everything else, I change the oil and filter, start it, and away we go!! The oil pump will fill the filter within seconds. When I start the engine in my car after an oil change, the red low oil light will come on for about 3 seconds, then go out.

A few years ago I had an old rotary lawnmower that ran good (always used synthetic oil) but the deck was rotted out and the wheels were ready to fall off. So, just for fun, I drained the oil out, threw away the oil plug, started it, ran it at full throttle, and went in for lunch! After lunch I came out to discover that it was still running just fine!! I waited until it ran out of gas, then loaded it on the trailer to take it to the dump!!
