I recently purchased an oc4....it was a bit of an impulse buy, but i have fallen in love with it. I have a few questions about it that I hope yall can help me with......it has a rebuilt Hercules 3 cylinder gas engine that runs really well. it has a 12 volt delco  alternator, I have a couple of  issues ...first is the left track seems to have to much slack in it, and want to tighten it , I have ordered a repair manual and an operators manual , that i hope will help out. also wanted to see about using it to move snow and to spread gravel on my driveway upstate as well s moving dirt.....can rubber be added to the track and made removable also? second problem is it seems to turn right better than left....is that because of the slack in the track&lt;? is there fluid that needs to be checked? changed? what should i do to it as a new owner?.......I have put new battery in it, dined fuel and changed it, changed oil and filter,new plugs......where can I find a distributor cap and wire set, points and condenser? thanks to everyone in advance.......
BTW it runs good, i had to free up the throttle and replace the choke cable..
the meaning of impulse buy was, I purchased a case 580ck from  a friend of a friend, the Oliver was sitting there with it in the ding weeds, and when I asked about it, he offered it to me with a 20' car trailer dual axle, for 3,000.....trailers worth about 1400-1800 .....and im happy with both, so i feel it was a good deal, but wanted some opinions.....thanks again to everyone, the breath of knowledge here is enormous.......
