CGT Restoration - Update

[Walde Libera]

Gents!

I rebuilt my 235 a couple years ago so I don't know if there are cooling issues yet, but here is some info I had when I installed the adapter plate, I don't remember where I got it from , but assume from the supplier of the adapter plate.

1955-62 water pump adaptation

When installing a 1955-62 235/261 full pressure engine in place of a 216 or early splash 235 engines, this one time conversion allows you to put the early style pump on the later engine.
In the past modifying the 1955-62 water pump was done but required a press to force the hub further back on the shaft, then the hardened shaft that was left protruding required being cut off. Additionally a special pulley and fan was required. After all that the pump and fan still sat 3" lower than the 216/early 235 pump that could lead to overheating and possible fan hum.
By using this adapter with a 1941-54 water pump the pump is put back in the stock location*. If you need to replace the water pump in the future you can buy an over-the-counter pump and install it without modification.

Note: I recommend using the harmonic balancer and water pump with the belt width you want from your original engine.
1941-52 ⅝" belt
1953-54 ⅜" belt
1937-40 must use one of the above

Caution: Do not use the 1955-62 balancer since the pulley is larger and will turn the pump too fast.

* Stock for 1941-54
* 1937-38 fan will be ½” back from stock.
* 1939-40 Belt and fan will be ¼” forward from stock.
