Build Off to a Good Start. My '74 40 Series

There was a tool roll or bag available, it had quite few tools in it. They come up for sale in the classified section periodically. Don't lose the strap hardware, it's no longer available. If you search tool bag straps you'll find info and sources. 73 to 75 used straps. I've made and sold aftermarket ones in the past. The green nylon ones have the original hardware. Stock straps were cloth.

Edit: if you search the classified section there's probably more info there. If you reference my name you'll find a thread with stk strap lengths.

Does anyone else use their 40 as a workbench?
Seeing the OBDII reader, you know I'm not working on the cruiser. Replacing wheel bearings on a family members Silverado. Ahhh technology and wonderful IFS.

It’s been a long time since I’ve SEEN the bed or wheelwells in my 40s! Both are permanently set up for adventuring.

Last weekend I took it out for a cruise to run errands and grab lunch. The weather was perfect for a drive. I started to notice a slight squeak coming from what I would think is the throwout bearing, maybe? That afternoon I pulled it back in the garage, put hubcaps on and then started looking into the clutch. Still unsure if thats exactly what the squeak is. First thing I notice, the clutch petal was too low. Clutch petal height should be at 8.6 inches according to the manual. I adjusted the petal but unfortunately ran out of time to go for another drive.

This weekend I pulled thr Bronco in for an oil change and parked the 40 out to get a little sun. After I was done with the oil change I took the 40 out for a drive for a couple hours and I notice the squeak is still there but it is not constant. It comes and goes. It doesn't go away when I press the clutch. I thought I recall a throwout bearing would stop squeaking if the clutch is pressed but I don't know for sure.

If the throw out bearing is riding on the pp you might hear it. You can remove the inspection cover and take a look.
 
Bring it to the swapmeet next Saturday and I’ll have a look at it.😉
 
After the swap meet today, I got home and checked valve clearances and made a few adjustments but the valve valvetrain looked to be too dry or not oily enough IMO. After making the adjustments I ran it a bit to see if I could see oil pour over valve rocker/assembly but I did not.
I ran out of time and had to move on to other things but I'll dig more into it later.

That is BONE dry…and…that is likely what your squeak is. @majdomo and I conferred briefly about this exact possibility after listening to your engine.

What I don’t understand is how that could have gone unnoticed since you said that the valves had recently been adjusted by a well known shop in Stockton?

Has the rocker arm assembly been off the head recently? It's hard to put back without lining it up correctly, but the bolt in one of the towers fits into a detent in the rocker shaft as it goes through the tower, so that the oil runs up the tower, into the shaft and out the arms.

I haven't ever pulled it off. The PO says the motor was rebuilt ~10 years ago but I have no receipts or records of it.
 
Ok. So it's getting pressure and circulating at least past the pressure sender, but not through the rocker arm. Only thought I have there is pulling the rocker assemby and dizzy, checking all the passages in the rocker shaft, tower, and arms for blockages and running the oil pump with a drill to see if you get oil up through the bore in the head. Which is super involved, maybe others on here have a better way to diagnose...

Thanks for this. I appreciate you for sharing. I wasn't sure where to start.
