My belt broke & I replaced it but 69 VW will not turn over HELP

[1FineOLD69]

when i turn my key and try to start does that make the large pulley turn? because i don't think when i try to start my large pulley is moving.

Also when i try to turn large pulley by hand which way should i be turning it? clockwise?

can i try to start it without the belt on just to see if large pulley moves?
i know now not to leave it run due to overheating, just trying to confirm if my large pulley is moving at all.

You should be able to turn it either way but when the engine is running the normal direction of rotation is clockwise.

Just put a socket on the big nut on the crank pulley and see if you can rotate the engine.

Trans must be in neutral for this to work.

if it doesn't turn, it's gonna be expensive.

If the engine is turning over when you turn the key to the start position the large pulley is most likely going to be turning. The key that holds the pulley to the crankshaft would have had to have sheared for the pulley not to turn if the crank is turning.

Yes you can pull the belt off and try to run it for a minute or two. Not longer. There is a chance that the alternator bearing has seized, or the fan broke and seized, and that shredded the belt.

Ok I removed the nut on the small top pulley, then removed the pulley its self to count the shims. I have 6 shims total.

I then replaced the shims and pulley how I found them and screwed the nut back on using a 21mm ratchet and screwdriver to hold the pulley into position.

I tightened the nut up using the ratchet as tight as I could by hand.

using the ratchet without the screwdriver to hold the small upper pulley, I was able to turn the small upper pulley and witnessed it also turn the large lower pulley as I turned the small pulley with ratchet.

I felt it was time to try to turn the key and give it another shot.

I took note of the large lower pulley position before turning the key to the start position.

After trying to start I can definitely say that the large lower pulley turns when I try to start using the key.

Two things I also noticed that I would like to mention are:

1) while using the ratchet to turn the small upper pulley I noticed some times it would grab the belt and also turn the lower pulley, but other times the small upper pulley would turn and the belt would just (I guess you would call it) slip.

Now I did tighten the nut as much as possible by hand so I'm guessing maybe I need more shins? as mentioned above I have 6 shims

2) also worth noting I did use wd-40 at first lightly on the 21mm nut to break it free originally when I began this job. using a paper towel it was all wiped clean several times. but the thought did cross my mind maybe its causing the slipping

Pic of my Fuel filter. you can see fuel level in the bottom of the plastic tip just above the hose clamp but not even in the main filter area at all. looks low to me.

should this filter be full of fuel?

If your generator pulley ( the one with the shims) is slipping much while trying to turn the crankshaft pulley, then you need to take a shim or 2 from between the halves and this will tighten the pinch on the belt a bit. Put the removed shims on the outside of the generator pulley under the nut, so you still have them on the shaft and your total thickness doesn’t change. With 3verything tightened down and the belt running true, you should have about 1/2” to 3/4” deflection when you push on the outside of the belt at midpoint between pulleys. In your travels, you ordered a Bentley and or a Muir manual right? Right? I can’t tell if there is fuel in the filter or not from here. If it’s empty, then that is a problem.

Generator belt is usually 9.5 x 905 at least in Continental brand. Alternator belt is usually 11.3 x 912 in Continental brand. Yours is a touch large if accurate. Do as Wildthings says until you get it to move the crankshaft pulley without slipping and it has proper deflection. You may need to move the gen pulley with a wrench to get the crank pulley to move. 19mm maybe? Can’t remember...G’nite West Coasters!

The mechanical pump sits top center on the engine and looks like this:

Electric pump come in a variety of shapes and since they are aftermarket can be located in many places between the fuel tank and the carb.

My Muir isn’t quite that bad yet. They do get some abuse!

Get your new Muir book, head down to beach, and read from cover to cover to get in touch with the Ass that bears you.

This will save you about $2000

I'd guess that you have the wrong belt size, and somebody correct me if I'm wrong, but didn't VW use 9 shims on the generator pulleys? I also swear I've read that you should have a minimum of 7 shims. Either way, 6 is not enough shims. In my younger and stupider days, I tried to cut down the number of shims once. It caused all kinds of belt/pulley problems. Just my ¢0.02. Good luck!

Pour a little bit of gas down the carburetor and try to fire it again. You are force feeding the engine some gas so it should fire if it has spark. If it doesn't fire then it's time to check for spark.

Pull one of the four plug wires off of the distributor and hold it just above terminal you pulled it from while someone cranks the engine to see if it sparks then report back what you find.

The belt is somewhat irrelevant at this point. It will run with or without it.
The likely scenario is that the carb, fuel tank or pump is gummed up or not working due to it sitting for so long, or the points are constantly closed not allowing the ignition to spark.

Change your fuel lines, relocate the fuel filter on the other side of the FIREwall and get the idiot book. That's too nice of a Bus to be sitting around for years without use.

I've never been able to turn the crank on any of my VW's by spinning the gen/alt pulley,
unless I first took the spark plugs out. If I could, I'd say I had some pretty miserable
compression pressures.
