Case 644 repairs / rebuild...

[RoamingGnome]

I'm starting some repairs / improvements to the Yellow 644 loader, (aka Sunshine)

One of the first projects is reconstruction of a previously modified battery support tray.

Fortunately, I took some photos of the stock battery support in the Red 644

but didn't take any measurements - I can figure out most of the dimensions based on what was left on the old support,
but was wondering if any of you have a 644 handy that you could take a couple of quick measurements for me?
"A" is the gap between the bottom of the support and where the battery actually sits,
"B" is the depth of the plate
"C" is the height of the side before the angle cut starts
Unfortunately the Red 644 is 5 hours away up at the property and I'm hoping to get the Yellow 644 fixed up before winter sets in...

Based on the photos I took - I'm guessing "A" is about an inch, "B" is 5.5" and "C" is 2" ???

I'll be sharing more pix and stories as I make some progress
Thanks in advance - Gerry

@RoamingGnome Gerry, What year model is it?

@RoamingGnome Gerry, What year model is it?

Both loaders are 1974 model 644's - I bought both of them from @Eugen last summer before he moved away - He did a great job of documenting his repairs to them - I'm just tweaking a few things to carry them on a few more years...

Been working on the Battery support the last little while of course around here nothing ever seems to be easy or straight forward...
Started by dragging a 4x8 sheet of 1/8" steel from behind the shed and cutting a 6" slice from the end of it.

Somehow It seemed to weigh more than when I put it there 20 years ago
Engine hoist to the rescue... Google says the sheet weighs about 200 lbs
Made some educated guesses on the shape and size and laid everything out using CAD - (Cardboard Aided Design)
Then crossed fingers and eyes and hoped everything stayed square as I gave the steel a few bends in the PA 12 ton press.

(My homemade 90° die set is only 4" wide - the plate was 5.5" I really need to make a bigger/wider die when I have the chance...)

I was very happy how it turned out - - making multiple bends on a plate like this always causes anxiety for me

Gave it a couple of quick tack welds so I can test fit and check clearances when the lights come back on in the BigSky™ Shop tomorrow morning.

I'll have a chance to check the space between the battery and the motor tomorrow, I wonder if making the edge flush with the battery would give better airflow between motor and battery? - If everything is good - I'll finish the welding, splash some paint on it and start on the next bit of the project.

Quick question for people that have a 644 - Does your battery sit flush with the edge of the support? I made my plate 5 1/2" deep so there is a 1/2" lip - the battery is a hair over 5" deep.
