4-speed is making this noise. Is what I have read that this can only be the input bearing true? Hoping it could be an adjustment that doesn’t require a trans tear down, but probably wishful thinking.
If it’s just the throwout bearing, you can do that yourself with a little knuckle banging. Since you’ll have to drop the trans to do that job, you can check the input bearing in the process.
Thanks for the feedback so far. Ok, so either way I am looking at dropping my first transmission to see what’s going on.
That opens up the whole “while I have the trans out” can of worms…
Should I plan on a complete rebuild or just do the faulty bearing?
Plan on doing the clutch too or do that at some future date when it needs it?
As far as process goes since this is my first time dropping a transmission…
If you would not bother with the clutch now, is it easier to remove the trans by unbolting it from the bellhousing rather than taking the bellhousing out too?
Does one have to worry about bellhousing alignment when reinstalling the trans with the two attached?
I would plan on replacing the clutch disc and throwout bearing and transmission / crankshaft bushing at a minimum. If the pressure plate looks bad or has loose springs then it would be a candidate for replacement too. The flywheel if it is scored or cracked would be time to replace too.
If this were 30 years ago then it might be time to have the flywheel resurfaced. Unfortunately any flywheel that was cast in 1969 is a ticking time bomb. If it truly looks perfect it might be able to stay. If there is any noticeable defect I would trash it to ensure that I had feet in the future. Maybe even if it looked fine. I like having feet, eyes, hands etc.
It is not the throw out bearing. A throw out bearing makes noise when the clutch pedal is pressed on. Usually a high pitched squeal. When you press on the clutch you stop the tranny from spinning. As you engage the clutch is when the tranny starts to spin and you hear your noise. It could be the front bearing in the tranny, but in order to change that you need to remove the tail shaft housing and drop the cluster gear. I have rebuilt numerous top loaders, Muncies and t-10’s. Once you drop the cluster you might as well rebuild the entire tranny. Not to expensive but there are numerous tricks to performing this task.
If you wish to try to rebuild it there are a few special tools you need and I can talk you through it.
