 |
|
I have a terrible noise coming from my mainshaft bearing. Can I replace that, or is it time for a new transmission?
Also, would it be beneficial to replace the 71 swingaxle with a IRS trans?
Anyone got a "freeway flyer" they want to sell?
Thanks |

You sure the Throw-out bearing is good and not making the noise? So, does your Bus have a '71 trans coverted to swingaxle? Normally, a '71 is IRS, but can be converted. |

Pretty sure it is the mainshaft bearing.
Noise when in all gears, including neutral, when clutch pedal is not depressed.
Once I press in the clutch pedal, it goes away.
Accelerating/decelerating makes noise louder.
Also happens at stand still.
"Seems" to get better once the trans warms up, but that might be wishful thinking!!
Trans number is A0289082, which I believe is from a 71 Ghia.
I found a topic on thesamba that says I can pull the nose cone and replace it. I will try it this week. |

| Sounds like a throw-out bearing to me. |

Try getting it warm and changing the fluid first.
Your trans has been changed from IRS to SA if you read the numbers correctly, a 71 Ghia would have been IRS.

I tried changing the fluid after a test drive.
It is either an AO or an A0. ???
If it was a throw-out, it would make noise when I pushed the clutch pedal in and go away when releasing the pedal. Correct me if I am wrong. |

Yes, clutch pedal in, if a noise, throw-out bearing most likely.
Trying another trans is like playing the lottery, except more effort, dirty clothes and no possibility of piles of cash you have to pay 40% plus on.

Thats what I was thinking. I can get a mainshaft bearing for $50. I will pull the trans and check it out this weekend.
Thanks |
