Better sealing available for ECE muck spreader auger gear boxes.
There is a tendency for muck to fall through the hole in the auger deck and thence through the seal and into the gearbox. There is now an extra seal available which attaches to the bottom of the auger drive dog, see photos. The later dogs have a shoulder on the bottom for the seal to attach to. It's not difficult to reproduce this shoulder if you have a lathe, just weld a suitable size washer to the bottom of the dog and then turn to size. Another improvement is to fit a steel disc to the bottom of the augers, this also has the advantage of strengthening the paddles. If you fit the disc with the augers inplace you will need to cut the discs in half and weld back together as you weld them to the auger. You may also need to remove a small amount of metal from the bottom of the paddle mountings, see last pic. You can also make rings from, something like 8mm round bar and weld them to the underside of the discs and the top side of the auger deck to form a simple labyrinth, the dec rings smaller than the disc rings. You can just see the disc ring in the picture. We can advise 01609 773607. With or without these mods it is very important to check the gearbox oil level and color frequently and top up or change as required. Make sure these dogs are well greased during assembly and have a good o ring in place, the o ring can be seen in the first pic.
The first pic is an auger gear box full of muck. The second shows a new type dog on a gear box with seal fitted. Next is a new type dog with seal fitted and an old type dog. Next is a new type showing the shoulder and the next picture is, left to right, new type, new type with seal and old type.
