 |
|
| Recently sealed the engine on my 74 914 2.0, re-assembled it and stuck it back in. Runs great, no leaks anymore. But.... she throws her belt. Took a look (with a camera) and the alternator pulley is ahead of the cooling pulley. No wonder she throws the belt. The alternator is as far back as she can go now and it's still out of alignment. It's like I missed something between the cooling pulley and the case. Anybody ever run into this? |

The alternator pulley is on backwards. On a type 4 engine, the notches in the pulley face away from the alternator. On type 1, the notches face the alternator.

I agree to the above. The pulley can be twisted with the alternator still in the car but be careful with the Woodruff key.

| Thanks, Jacks. That is exactly what the problem was. Turned it around and all is well now (and aligned too). |

I found something once that had the opposite result: This on a factory rebuilt by what was its name, GEX?, advertised all the time, shitty rebuild record.?
Whoever put the hub on the crank, lost the key, but it was still up in there laying flat by the crank. They put in another and cinched it down. But the 1st key kept the hub from fitting tight on the taper. Some thousands of miles later, the key wore out from moving, and the fan stopped cooling. I took it in as a core. The valve springs were black and the valves seized in the guides. Most of the exhaust valves were stuck open. I fitted a new key., (removed the problem, rebuilt the heads, put it in my 1980 Westy. It uses a bit of oil, I suppose the rings were hurt a little, but the cylinder walls looked good. The motor works quite well for having been roasted.
I really doubt ANY engine builder but a production line worker would have left the extra key in the engine, but when the hub fell off, I could see it in there. So this is one POSSIBLE cause of the fan pulley being too far out from the case (rearward in a Vanagon, forward in a 914)
