After rebuilding a used conquest that we picked up a few years ago i can say changing shafts when bearings are seized on sucks! I want to be thorough with maintanance work on my new 750 hdi to greatly reduce repair work. What are issues to watch for on the hdi? Also i have been told not to over grease bearings. In the winter how often do you guys recommend greasing bearings and how much grease? In the summer time how often do you guys recommend greasing and how much grease? Do you guys grease after every single encounter with water etc.. My argo will never sit out side in summer months and i know to always drain any water it has out asap. Any tips for chain maintanance or recommended lube? Sorry for all the questions. Just want to do what ever i can to prevent having to work on machine all the time. Most of my use will be slower 10 to 20 mies trips at a time for hunting and scouting
