Water Pump Keeps Falling Off

[StoneSlayer]

The water pump falls off at idle - no throttle input whatsoever. It falls off regardless of the belt tension, and regardless of whether or not the belt is installed.

I have completely removed and reinstalled pump, pulley, and belt several times. I have even tried using the MSC Editor, to bolt it on, and it still falls off.

After I have reinstalled it, either via the editor or manually, I have tried right clicking on the pump. The pump cannot be removed by hand, unless I remove the bolts.

I purchased the game after the train update, and have not tired creating a new game. Is this a bug with the new update? Or is there a specific way to get the pump the stay on?

Also, how many nuts or bolts are used? I only see 4 nuts and 0 bolts for the pump (4 bolts for the pulley), but I read on another discussion that there were 4 nuts and 1 bolt for the pump.

Any help is appreciated

Thank you for the replies

I was able to figure out what I did wrong, and got it to stay on. Apparently, when I was first building the engine, I put the pulley on before tightening the nuts - the nuts can be seen easily (because there are studs for them), but the pulley was obstructing the bolt. I also kept missing the bolt, after installing the engine, because of the angle I working with, and the bolt being hidden behind the pump shaft.
