Message: <blockquote data-quote="nobull1" data-source="post: 10549" data-attributes="member: 722">When I purchased my 763 The gearbox was low on oil and the fan was making a little noise at idle (probably backlash on gears). I had a hard time getting the plug out, and almost stripped it. After replacing the oil it seemed to be about 80% less noisy and acceptable. Just lately I have been getting the noise again and decided to check the oil. Well!!! should have changed that half stripped plug when I had it out, because now it is stripped and not coming out. Or I should say it won't be easy.So the questions are:1) Is there a easier way that people have used to get a stripped plug out.2) Is it worth trying to get the leak fixed or should a person just replace the assembly(new assembly about $900.00) and be done with it. The gears seem to a have a little bit of slack, but not a lot, but who knows for sure the condition, until disassembled.3) Anyone done this repair job, remove and replace or remove and repair? Bobcat says about 3-4 hours labour, depending.4) How long might it work like it is now. Bobcat says they have seen them go between months and years making the noise. If you just set the idle up a little the noise pretty well disappears.Suggestions welcome</blockquote>
