Pretty new to the ride-on side of house and as such starting from the bottom.
I have a stockman series 2 which, by all accounts is in good shape however it does make some interesting noises when moving.
I was told when I collected it that it was the drive mechanism that can be 'easily' replaced and after research I understand the component the seller was referring to is the drive cone (kit187).
I am however, unable to really identify the indicators for when the cone ctually requires replacement. As mentioned the drive train makes some serious noises operating the foot pedal but I don't want to spend $150 on a cone if the noise is from a bad bearing or something.
I have checked the gap between the cone and drive plates and they are. A touch over 1mm each side (I understand it should be 0.8mm to 1mm) and there is no slipping when operating.
Is there a cheaper, simpler culprit I can look at first? What are the replacement indicators for a worn cone?
There aren't really any indicators as such for a worn cone, only that the diameter gets very small and you have to use a lot of pressure on the pedal to get drive. Does it look like the sheaves have been moved on the shaft? that usually indicates that the cone is worn and someone has adjusted to suit.
There are bearings on the cone shaft, the upper drive disk shaft, and the rear axle that can be seized or worn. the chain if dry or worn can make similar noises.
What I would do is jack the rear end up so the wheels are off the ground, turn it by hand to try and find the culprit. then maybe drop the chain off, that will isolate the shafts a bit better.
They are easy to do in some ways, no gluing like in a greenfield for example, not a 5 min job either though, the whole yoke i guess with the cone on it needs to be dropped out so you can get the shaft undone to replace it.
I haven't got too stuck into it today, more likely to be a weekend job. I did, however, jack it up quickly and put some inox on the chain and take some additional pictures.
The only real noise seems to be coming from the cone/drive discs rather than anywhere else.
Here a some pictures though just to give better context.
Used to run service department in an Ag dealership when these were new, we were a dealer and sold a heap. These had a lot less bodywork issues than the originals Love these old beasts.
I'd be changing out that cone and cleaning up the discs. We used to jack them up and jam the pedals down and use a big flap disc on the grinder to machine up the discs. Worked a treat. They're a bit like car brakes and become polished smooth and get noisy.
Cheers for the info. Did you take the discs off to get the flap disc on them?
Next I'll be working out how exactly to conduct the swap of the cone. I saw some info somewhere around but it didn't make too much sense. If I remember and im not too busy cursing I'll try to document my progress
Yep that cone is gone! will transform the mower when you put a new one in.
I would say you don't remove the disks, need to keep them as round as possible, short of pulling them out and getting them machined.
The cone on those is not too bad. First off loosen the drive disks and spread them apart. Drop the engine belt off, then the pedal linkage. Then you should be right to remove the hinge pin. the whole thing should twist around and drop out from memory. its never quite that easy though.
No leave the discs on. Just jam it in forward and run the disc on them until the shiny stuff is gone. Makes a huge difference.
From memory it's just one bolt through the centre of the cone. Hit it with a rattle gun and it's out!
Hi Motowerx, i know this is a old thread but i thought id try ask a question, Can i use the rattle gun to undo the drive cone bolt and just use the pressure of the drive belt to hold the bottom pulley in place while using the rattle gun ?
