I am looking at this adapter plate and am ready to take the next step. What do I need to take off to get this plate off. Peter, you mentioned engine and trans. mounts, etc., and possibly the muffler. Are there any other surprises behind it? What parts will I need
besides the main oil seal?
Thanks again ........ Gary |

The OEM for the rear main is Corteco. Their part number is #12012521. VITON double seal. If you can't find it just ask NAPA to cross # the number.
The replacement most likely will be C R. |

Could someone post the 'generic' rear main seal part #? I may be doing a clutch soon, and would like to have one on hand in advance. |

Sorry Gary, I misread your post. You just want to know which seal to get. Personally I would use the Napa one that Edward G. suggests. |

Gary, You ain't going to get any closer to it then you are now. As Peter says change it, Good insurance. You may not like yourself if it starts leaking in 6 mos. if you don't replace it. |

Peter,
Thanks for the info. It seems as though the problem is going to be getting the plate past the shaft. I'll start the process this week. Is it worthwhile buying the expensive rear main oil seal ($80)or stick with the one you guys suggested.Is there anything I'm not thinking of.
Any other info. would be appreciate ...Gary |

Progress report. I have the flywheel off and will send it out to be resurfaced. I am looking at this adapter plate and am ready to take the next step. What is required to get this off? Are there any surprises behind it? What parts will I need besides the main oil seal? Does anyone have a picture? The books that I have do not illustrate this plate.
Thanks again ........ Gary |

Rear main Seal... ...!!
Standard size, you can get it at any respectable NAPA Auto Parts. (Don't go to Ferrari)
I think it's a 80mm X 10mm
Grease up the shaft and the seal lips with black Moly Grease prior to install. Dont get grease on the outside of the seal or in the aluminum engine case, or the seal might pop out at 8,000 rpm.... . ..oops. |

Thanks again,I'm going to take the clutch and flywheel off today. I'll then pull off this adapter plate. Is there anything else I need to worry about or replace while I'm in there.
Thanks ........... Gary |

Gary, if you damaged the sandwich plate gasket, an inexpensive source for one is Dennis McCann. The gasket has a very large surface area and sticks to the case like super glue. Be patient and it will eventually come off. Might as well change the rear main oil seal seeing as you'll have easy access to it with the plate off. |

Thanks for the info. guys You are such a valuable resouce. I finally got the bell housing off with much persistence. I might have damaged the gasket of the adapter plate. The oil has completely leaked out. Is this easy to take off and replace the gasket or are there other remedies.I have a 83 308qv if that helps.
Thanks again for your valuable input ..... Gary |

What year is your 308? The bell housing guide dowels which are located around the 10 and 5 o'clock 10mm studs sometimes corrode causing the bell housing to be stuck. Are you sure that you removed all the nuts? There is an 8mm nut (4 all together)on the bottom that is easy to miss. The bearing on the trans. input shaft is not always a loose fit and sometimes has to be pulled off using a special puller. If you don't have the ring nut tool, how are you going to torque the new nut? Removal of the intermediate plate requires engine removal. |

In my case, the bearing came off easy. Or, you can stick one finger inside through the hole right above the input shaft and push out the bearing from the inside.
Then, you have to remove the retainer ring (oring with a cut out) 3 inches from the end of the input shaft. Then, the bell housing will slide off providing all the clutch arms and stuff have been removed.
I can get into the bell housing and back out in a total 2 hours, but the first time was hell. |

Gary, I did my clutch among other things last winter and Im pretty sure the bearing slig off the shaft once the snap ring was removed. As far as the oil leak goes, if you just loosened the nuts for the adapter plate, tightening them should stop your leak. If you have a damaged gasket now, you will have to remove the adapter after the flywheel is off and replace the large gasket behind it. it keeps engine oil and gear oil from mixing or externally leaking. Something to consider is the amount of work required to get back in there if you decide to cross your fingers and it ends up leaking after you road test it. |

After listening to the threads on replacing the clutch in the 308 I have started this project and have a couple of questions. The transfer case came off ok and I removed the nut from the lower gear without using the special socket. I then removed the smap ring from the lower gear. The bearing seems to be stuck so I removed the appropriate nuts to remove the bell housing and it will not move. Am I missing something? Also are there any other items that I need to look at or should be concerned about? I also loosed the nuts accidently, thinking it was part of the bell housing, on the bottom inside of the bell housing. That area now leaks oil. Is there a fix for that also.
Any help would be appreciated.
Thanks ......... Gary |
