Transmission/Clutch

[Siegmund52]

Thanks for the very helpful answers to my last question.

I have a 1952 pickup with a 1962 235 with three-speed transmission and 3.55 rear end.

Is it normal to hear faint rattling at idle, similar to loose rocker arms, but much softer?
When I engage the clutch all the way, it dissapears.
The pedal is adjusted to spec and the pressure-plate retaining springs are good.
I also have troubles sometimes, to get off the ground in 1st, keeping the engine from going into a fairly heavy vibration.
Only additional gas and quicker release of the clutch pedal can prevent this.
This just seems too tricky and not right for this otherwise beautifully designed machine.

I am thinking of going into the clutch, if necessary.
Are there any parts, I should get before-hand or should I install a new disc and pressure-plate all together.
I don't believe anybody went in there for ages.

I almost feel like the transmission could be a mismatch.
Or could I have the wrong size disc and pressure-plate, which causes all this?

Thanks for all the time and help.
Chris

I agree with Cowboy, "throwout bearing" mine did the same thing after I put the first motor in and the second one too. Everyone said to replace it, but after awhile it smoothed out. It did start back making noise after an extended period of being parked once. Something else that can make a slapping/low knock/tapping sound in a 235 is the pistons. I forget the term used, but there is a process that has something to do with the bottom of the pistons that if not done when rebuilding one of these motors will allow the pistons to make a low knocking or slapping sound. Maybe the term was knurled? I'd still go with Cowboys idea, its the throwout bearing.
