Steel plug over pinion nut - WF hydrostat transaxle

Post by DaveKamp »

Hey guys-

the WF iron hydrostat axle has what appears to be a steel cap or plug pressed into the transaxle housing to seal off access to the pinion nut.

Is there a clever way to remove this... to gain access to removing the pinion... without damaging it?

Dave - I assume it is same as with the newer aluminum rears, just an expendable disc type domed freeze plug. While rear is disassembled, easy to knock out, replace with new.

Cub likely still lists a replacement plug to eliminate guesswork for proper replacement part. Put some sealant around the edges and then hit squarely in the center with very large drift to expand.

Okay, thanks Tom. I didn't see a good angle to get at it to knock it loose, other than try to knock one side inward enough to get the opposite to pop out into vise-grip range. Izzat the standard modus operandi?

Dave - Been so long, I can't remember what I did. I think I drilled most of the way through then used a sharp punch to beat a hole the rest of the way through,then pried it out. Do not try to beat one edge in, the lip behind it will prevent that.

Here is my thread that has the rear set-up, but I didn't show plug removal: viewtopic.php?f=8&t=5282&hilit=cinderella&start=90
