You have to remove the Allen head plug towards the top of each Hydro-gear so the oil in the reservoir will flow down. You'll need about 4 1/2 quarts of oil. You will know when each of the Hydro-gears are full when oil starts to overflow out of the Allen head plug port. I usually leave about an 1/8 of an inch of oil in the reservoir when I put the plugs back on.
Don't put too much oil in the reservoir when you're done servicing it, about 1/8" to 1/4" is all you need to see in the reservoir. The oil will expand when it's hot and start fill up the reservoir.
If you don't mind my asking, what size allen wrench is used to fit the Top Port Plug? Also, any suggestion on how to get to it? I have busted every knuckle trying to get an allen wrench in to the plug.
Sounds like it worked out well for you Doug, nice job.
FYI though, I removed the plugs from the rear; used an extension, ratchet and socket/Allen bit. I went in between the drive belt for the deck blades. :smile:
This is what I did I removed the deck to get into it from the front.
Was it necessary to remove the deck ? I ask the dealer when I purchase my Raptor last month about removing the deck , he suggested on zero turn mowers if it's not necessary not to remove it .
