 Topic: D-17 seat replacement
Posted: 29 May 2015 at 1:45pm |
|
Started to replace all the pins/bushings in my seat and what a mess. Is there anyone making an entire seat assembly for my D-17? Like maybe Lazy-Boy? Don`t care if it is original, just comfortable. And no, I don`t want to bolt a car seat on it.

As you already know, bushings can be a real pain to change, dissassembly is the biggest task. I often revert to cutting torch and ziz wheel. However i believe the effort is worth the result. DJS tractor parts sells a kit and it is well worth the money. Installing a new shock on the seat will make the biggest improvement for comfort. I didn't believe it till i replaced my first one. Wow !!!! What an improvement.
Replacement seats are often to high and position the driver in less than optimum position.
Also the factory seat gives the user quick two position settings, upper for cockpit access and standing opperation and the lower position for sitting or youth position as i have several of mine adjusted for.

Taking it apart is definitely the hardest part. Drilling out the roll pins and using heat and oil on the shafts will get things apart. Once you get new pins and bushings, it goes together much easier. I have done several and have more to do.
As mentioned in the above post, most of the aftermarket seat positions actually make things more UNcomfortable due to the distance from the controls. Either too close or too far away. I also like the original look!

I managed to replace a few bushings to get me back in the field. Those dowels won`t budge, bent a couple drifts, smoked a couple bits trying to drill out. Have to try your techniques next rainy day.
Thank you gentlemen!

Amen to all the above. I rebuilt an original D17 seat. Your best friend is the torch, had to get everything glowing red before I could drive the rods out. But rebuild it before the bushing are totally worn out and the seat frame holes begin to become oblong.

Here is a helpful tact if you don't have a torch.
instead of drilling the roll pins, I just sheer them off. I know that sounds silly and aggressive but it really works and it is much less damaging to the seat parts.
Get a helper to hold the seat mechanism and position the seat pivot pin over a heavy vice with the jaws open just far enough so the pin will go through the jaws when hit with a 6 pound sledge from the other end. Usually one end of the seat pivot pin is sticking out so that is the end I hit. Moving the pin just a little will sheer the retaining pin off clean. Now flip the seat mechanism over and drive the pin in the opposite direction. Doing this several times will loosen the pivot pin enough to allow your penetrating oil and drift to be very effective.

Those roll pins are really hard. I couldn't drill them at all. I bought new bits and everything and still couldn't put a dent in them. I had to buy a special punch, one the perfect size, and as stated above, heat to dull red and drive them out. I bought the kit from DJ's Tractor Parts, I think the bushings and roll pin were sold separate. The pins look to be about an eighth inch in diameter, but I didn't mic them so I'm not sure.
