Hi,
I was reading DeQuincey's write up on installing a new water pump and radiator clearances (https://e9coupe.com/forum/threads/refrigeration-system-renewal-and-repair.6020/) and have a question. I am replacing the water pump on my 1973 CS with the same pump that shown below, which is, I believe, is the middle design between the early red blade fan with four bolts and the later E24 pump with the 32MM nut.
I know the 32mm nut is a reverse thread, but on this bolt in design, does anyone know if it is reverse thread or not?
Here is a photo of the parts diagram and the bolt I am speaking about.
I am having difficulty removing the bolt. At first I thought it might be a reverse thread like the 32mm nut is, but in reviewing photos online, it looks more like a regular threaded bolt. Secondly, I have the special holding tool needed for the 32mm nut water pump, but, with this setup, there is not enough clearance for me to get two of the bolts holding the adapter (part #6 on the diagram) to hold, making the tool a bit useless.
I am looking to confirm two things, if possible?
1.) Confirm if bolt #10 is a reverse or standard threaded bolt?
2.) How does one secure the pump and adapter when trying to remove the fan and pulleys to access the water pump, since the usual BMW water pump tool for use with the 32mm nut does not have enough clearance?
Thanks for any replies on this.
