Except for greasing at the nipple up forward, does anyone have any suggestions as to what order to trouble shoot this problem. It started out as an occasional hassle, and is getting progressively worse - unsafe. |

J&J, I have a 4106 so it may be totaly different than your MC7 but when my accelerator was sticking it was at the peddal pivot. There is an 1/8" pipe plug that I thought was a setscrew to hold the shaft in, when I removed it to try to drive the pivot shaft out I discovered it was a plug. I put in a grease zerk and tried to pump grease in but it wouldn't go until I worked the peddal back and forth a lot while holding pressure on the grease gun, finally grease came out both sides and it freed up. The problem began after a winter trip and I guess from picking up salty slush on my shoes, carried it into the bus, where it melted and got into the pivot points. Yours may be different but it will take little effort to check. Good Luck. Thanks, Sam |

J&J Pull your floor inspection covers (rear) an check all linkage,mine rubs on trans shift linkage . Also if possible disconnect at rear bellcrank ,to make sure which end or section is binding. There are several lube points at bellcrank,an when found remove an clean then lube an install all fastners. One more item have a return spring on, new trucks have 2 springs. |

I washed my driver's compartment and started having the same problem on my MC-7. I found out that water had made its way through the floor at the pedal, causing some rust in the mechanism and making it stiff. I came into town after a 3 hour drive and the engine wouldn't go down to an idle. Imagine my attempts at shifting!! I felt like a rookie because I couldn't gauge the engine rpm with my shift points. I sprayed some WD-40 down the shaft and the problem ended. Hope this helps, Henry |

JJ, Yes, pull the back floor inspection cover. You should see as I did on my MC5 the throttle linkage pivot point right there at the bulkhead by the blower shaft drive. There is a grease zerk there at this pivot point and I assume the long rod goes all the way straight to the front pivot. Grease & spray lube into the "black hole" Good Luck, Joe |
