Well put a 3.4 pulley on the old d1 got a smaller belt and put some belt dressing on the belt" sticky stuff" and went out to do a couple pulls and this happened as soon as it shifted out of first at 14psi.....




Any body else ever had this problem? Looks like water pump pulley just spun right off. is there a water pump pinning kit lol
truck was pulling like a raped ape btw , hardest ive ever felt.

 

I have never seen that before. Could be an isolated incident... Whats the status of your tensioner?

 

tensioner appears to be fine. so does everthing else some belt scuffing on various thing from it popping off but everything looks to be ok.

 

Is it the stock tensioner? You might need a beefier one. Slack in the belt on the downshift can move it on a flat pulley like the water pump pulley, enough to pop off the side just enough to wrench the bitch right off of the pump.

 

i have a hd tensioner, and that belt was a bi#@h to get on so belt was very tight.

 

Well ****, I don't know what to tell ya. Sounds like a one-off kind of break. Was it a clutch fan to e fan conversion, or was it always e fan?

 

yeah it was originally clutch fan. next question is there a electric pump that would work with my belt configuration ?

 

This is why i like turbos...

 

Dont kick the man when he's down, help him out...

But Ed mines never had a issue either.

Lol sorry man, 14psi put a smile on your face though?

 

Easy Fix bro!

Just put the pulley back on and weld it on the end.

Its been discussed before i have seen, so before i installed my blower i put a " dab" of weld on the end of my water pump pulley. No Problems !!!

Stock water pump is fine . I wouldnt mess with electric.

14 psi !!! That feels good!!!
