420 reverser, worth repairing?

Post by mulligan » Fri Oct 26, 2012 8:03 pm

My reverser in its past life had filled with water and froze. It had cracked along the bottom of the housing and I finished off the crack when I was removing the center section of the crawler.

First I was annoyed at myself for stressing the housing and cracking it, but once I found the old cracks I realized its better to find out now then after its assembled and leaking.

I can weld the housing, but I'm unsure if its feasible to rebuild this unit. It's trashed, the gears are rust pitted but otherwise in good shape.

Also, to top it off, the previous owner welded the shifter to the shaft. I can rebuild the shaft but the shifter cameoff in pieces.

What is the avg cost to rebuild? Does anyone have a good reverser for sale?

Personally I prefer a reverser crawler if at all possible. I would clean everything up and inspect it. I keep quite a few bearings and assorted reverser parts on hand, and am making some new parts if I can.

Is there a trick to get the propeller shaft out of the housing. I don't have the AM2047T tool listed in the manual.

I also found that there wasn't a detent ball and spring in the housing for the shifter. :roll:

Prop shaft will usually pop right out if you stand it on end and bop it on the floor.
I have no idea of where they go, but I have found the ball and spring missing too. I have them on hand if need be.
