John_AZ, was the water pump pulley method yours?

Years of belt tension experience, years of searching and years or reading water pump seal and bearing failure and belt failure.
I bought the '88 924S in 1995 before Pelican and my join date of 2001.
I owned a couple early Porsche and thought I should be able to do a belt change.
I bought the Krikit direct from the factory for $10.
Spent a full weekend on the cam belt tension and waking up with cold sweats the first couple of belt changes. Probably redid it 5 times and still worried. I did not trust the Krikit.
The water pump pulley test is a combination of many members methods and cautions about the water pump bearing and seal failure caused by an over-tensioned cam belt..
The earliest mention of the pully test was in the late 90s, "I put my fingers and thumb on the WP pulley and tried to move"--member ID lost.
I have revised the method with suggestions from HondaDustR and many others.
I take credit for the yellow background
The Krikit is almost impossible to be accurate twice in a row for the cam belt. The indicator lever is not calibrated enough---only to be close "with multiple readings".
I use the Krikit on the BB balance belt.
With a new cam belt---any method should have more tension as the belt will stretch and fit in the cogs. The Porsche OEM tool-P9201 has specs for a new belt (which have changed but close). The Krikit new belt specs vary ??.
Re-tension is now suggested at 500 to 1000 miles.
Finally, keeping a cam belt on for 30-45,000 is a fools choice.
Both my 924Ss came with a rebuilt WP installed prior to purchase-in 1995 & 1998. Still on the same pumps-one on the shelf waiting...
