alright so bobcat already sent chains out but they said i can return them. my buddy owns a hardware store so i had him order me a 20' length of 80HD chain with 4 master links the only thing im missing is the tool to cut the chain but im sure i can just use a grinder unless you have another way. so im going to replace all 4 chains. i ordered 4 axle seal kits which each kit consist of 1 - Axle Seal replaces Bobcat part number 6513277 2 - Bearings replace Bobcat part numbers 6689775, 6669050, 6519925 2 - Races replace Bobcat part number 6519926 i ordered a new rubber gasket seal that goes in between both access panels and im going to fill it with 15w-40 oil. all the sprockets, e- brake, and axle's look good. so after i do this i should have just about 100% undercarriage. is there anything i missed? also should i put a quick weld on master link or should I be alright. i should have everything in my mid next week so ill be putting it together by the end of next week. thanks for all your help so far. i had posted another subject a couple weeks ago about the blow by which it is what it is for now im just gunna keep my eye on oil if the motor blows i can always get a remanned or sumthing. we do auto dismantling and scrap metal recycling so the machine gets used everyday most of the day im never gunna have down time to pull motor and rebuild it
