Morning, This is what I found when I rebuilt mine.
This appears to be a repair from years ago.
The shellac appearance is probably from old fuel.
I used cork from the HOME DEPOT to replace these.

This is a picture of my 37 115c fuel sensor,
The primary issue was the contact had stuck on place and the spring could not push it to contact the wire resistor.

PM me and I'll send a series of Photos on how I shop repaired my unit.

Bypass oil filter install on the 37 6 cyl.

Ebay purchase of the canister / mount for a 50's "Packard".

With several members input and photos I designed this mount and piping configuration.

I accessed the front port o n the oil gallery

While I had the timing chain covers removed I was able to run the feed pipe behind the backing plate, I used a piece of rubber tubing to protect the line from rubbing on the plate or block.

I decided to use the Oil filler pipe as the return point so if in the future the filter is removed than there was no hole in the block.

The inlet to the filter has a 1/16 reducer to reduce the possible loss of oil pressure.

ADMIN ; please rotate pictures, Thank Larry

This installment

HAD ISSUES WITH ROD BEARINGS

SO Here is the latest on the ROD BEARING issue,

The problem revolved around the sizing of the rod journals, the ".010" over bearings a and 2 replacement 39 rods ordered in for pin bushing issues.

1. The crank was turned .010 under and I did not realize 37 .010 bearings are not available. ( MY MISS, not the suppliers) This resulted in purchasing 39 and up .010 over bearings.

2. During reassembly the Mains worked very well, As discussed above there were issues with the rods.
The final answer to this is,,, The .010. bearings were the same size of the journals, actually I believe they were about .001 smaller ID than the OD of the journal.

3. Back to CUSTOM CRANK , Bill did a GREAT job in resizing the journals to fit the replacement rods and bearings to correct fitment,

4. While at CUSTOM CRANK Bill identified the 39 rods were a touch too thick and sized the one he had.

5. 39 rods are heaver than 37 rods,

6. Reassembled all rod caps with bearings, Flat sanded the sides of the rods and matched to the 37's, removed some material from the sides of the 39 rods ( casting excess) until all 6 with pistons matched in weight.


Cost for this repair, 2 hours shop time and materials, about the same to as the crank turned the first time and a new set of rod bearings since the set I was installing got messed up.


LESSON LEARNED,,,,, Verify , ( the info was printed on the .010. I just missed it,,,,,,) Get your rods bearings etc gathered up then have the crankshaft turned to spec.

Removed the graphite seal.

Removed all rod caps, wiped all pre-lube bearing surfaces with 30W,
While cleaning I saw that the edges of the bearings were being polished and the centers were not.

Discussed this with the friend who is assisting and he questioned a radius at the edges of the journals.

That brought back the discussion with the crank guy that he was going to do a radius,,,

From what I remember from last summer the crank was square cut on the journal to counter weight and he was going to add what ever radius he could.

So on Thursday we are going to do the adjustment to the edges


More later this week

Thanks for the info.
I am Using a best gasket set that had the graphite rope and install instructions for a Packard.

The oil slinger now makes sense since it dug into the rope.

I'll be getting it removed and retorque the bearings.

Thanks Larry,
Oh.

Thanks for educating
