, I saw oil at the filler stick and oil running down the leg extraction pipe and at the nut at the bottom of the extraction pipe. There was a small amount already in the grooves of the rubber diaphram.
So I presumed that the oil had leaked whilst running the engine
Reverse was only selected to get back into the pen and when going out I went into forwards and took the revs up to 2800. Oil is still clean, not brown or milky.
Dipstick shows oil level at bottom line. ???
PS. Can anyone tell me whether or not the gear
box should be filled with auto transmission
fluid or engine oil as I have conflicting reports?
The reason I asked is that I assumed the oil was coming from the dipstick also. But then I noticed small pools of oil above the dipstick and around the mounting plate where the shift rod enters the drive. Figuring all that oil wasn't traveling upwards I then suspected the mounting plate. I removed the plate and resealed it and still had the same leak. This left one area to leak and that was the seal on the shift rod.
To really verify the leak before I ordered the seal, I wrapped a piece of 1/8 line around the raised post where the shift rod goes in. I left six inch "tails" on the line and made sure the tails were not touching the gearbox
. After the next run, sure enough oil was dripping off the line. Since I figured all that oil wasn't running upwards
towards the line, it had to be a bad seal.
The oil I use the same oil as in the engine. I have the 130....
