I am changing the valve cover gasket on my 6080 and noticed the previous owner had oversized nuts as spacers over the shoulders of the bolts. The parts book appears to show a stack of flat washers as spacers. What is the reason for this and is there anything special about them. Can I use ordinary flat washers instead? Many thanks! ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| They have to have the correct number of spring washers or it will tighten down too tight or too loose. If I remember correctly it is seven spring washers. MACK |

It should be a shouder bolt so it wont tighten too tight. Ive never seen one leak with that shoulder bolt and spring washer kit ------------- 1984 80780 1957 D14 DES 300 with 25000 engine 616 tractor |

| They are NOT flat washers.They are kinda "w" shaped. I was thinking they face each other every other one. It's what's on 8000 series 426's. |

| They were shaped like a disc blade. Every other one was stacked and it was like a spring. |

They sound like 'bellevill' (sp) washers, which are a form of spring. |

| Bellville washers. Seven of them taped together to make them as one. Trouble is with time and heat the tape deteriorates and then you have seven individual parts laying in a pile. |

| Sooo....positioning is...with bolt in position, bottom one facing down against cover then next pair facing each other then repeat again for the 2 pair left? Only trying logic. How'd I do? |

I'd say because the washer setup would last longer....My 220 just has Phillips head screws through the gasket. Old school it is but has never been a problem in over 30 yrs.
