what is this hole in the floor for in 50's chevrolets?

here's a 55, a 51 has the same hole and I was just wondering if anybody knew what it was for.... the one on the hump up by the firewall.

 

For getting to bolts on a cast iron power glide

 

It looks like it would be an inspection cover for your clutch throw-out bearing. Wish my Ford had one. I had to remove the entire front floorboard!

 

This sounds about right. HRP

 

I always thought it was for better access to the upper bellhousing bolts, but I may be wrong...

 

I don't have anything with a motor in it around here. I'm pretty sure my 49 has one too, so that would cancel out any powerglide related answer.

 

Upper bell housing bolt access.

 

By memory I think that was used to put gauges on the powerglide for testing purposes.

 

good question, I have wondered the same. I thought about welding mine shut, (reduce fumes from coming in) but having access to remove bolts if I wanted to pull the motor without the trans would be nice.

 

That is for getting to the upper bell housing bolts, I've done that many times back in the day.

 

i say transmission bolt access. i dont understand how one could see the clutch throwout bearing, unless the bellhousing is transparent? i never seen a transparent bellhousing???

 

there is an access hole in the bellhousing for something, probably throwout bearing or something with the clutch.

 

I have it on my 54 as well. I believe it's there for access, used to index the torque converter to the fly wheel.
