Recently I discovered 5 loose and 1 broken bolt on my 1533 and ordered replacements from the dealer.  The broken bolt is unique as it has a longer shank to function as a dowel pin for casting alignment, but the other 5 are nothing special.  I decided to replace all six.  I waited over a month to receive these parts and was shocked to find my dealer charging $12 each for the 5 and $17 for the special bolt.  Ironically, I paid $17.36 for an oil filter which seems fair.  Thankfully I don't earn a living with this machine, because waiting over a month for 6 bolts is just ridiculous.  I guess I need to shop another dealer for parts in the future.  Venting finished.  Happy Thanksgiving
