Why would an intermediate shaft be worth $40? Its not like they are in short supply.

They are hard to find when you need one
 and I've seen quite a few with the thrust surface broken off.
 A better picture of the beveled area on the gear would prove it's from a 1.6.

It's from a 1.6.  The 1.9s don't have the fuel pump cam.  I would think that if it is all in good shape then $40 is quite reasonable. 

[fatmobile]

 From that angle it could be from a 1.5.
 Can't see if there is a bevel cut in the gear to clearance for the 1.6 crank.

That seems odd. I have several and have scrapped a dozen or so because no one wanted them.

dude, we are on the west coast, people give VW diesel parts away..

Quit doing that, ha.

 A friend bought an engine with a caddy and we are putting it in a Rabbit and tuning it.
 The I'shaft thrust surface was broken.
 He has other engines so he grabbed one,.. that was also broken.
 He had to search through several engines to find a good one.

  I told another guy I'd change his timing belt. That always includes a check of the I-shaft and during seal change.
 His thrust was cracked. Common enough that I warned him that I wouldn't have time to fix that before I started the job so handed it back to him that way.
 I searched for one for him and found a cheap one but the guy took a long time to ship it.
 He got impatient and got one from the parts place for an outragous price installed it and the crank hit the gear,.. they sent him a 1.5 I-shaft.
 By then mine had arrived so they took everything apart and installed it.
 Even after that I saw the Parts place selling a 1.5 I-shaft as a 1.6 on ebay.

Just curious, what would cause the thrust surface to break on an IM shaft - broken gear teeth?
Reason I ask is that I turned a 1.9 shaft down and fit ball bearings on the belt end. I noticed a slight buffing of the thrust surface to the end cap, but nothing serious.

being a helical cut gear, there are thrusts generated when these gears mesh..

when the IM shaft is spinning, its constantly trying to be pushed out of the block..

without that thrust surface, the gear thrusts would literally push the IM shaft right out of the block..

if you put ball bearings on the IM shaft, that should take care of the force generated from the spinning helical cut gears..

I get that there is thrust - just trying to figure out how there could be enough to break off the flange.
I just tested my new pump using the 14 mm socket on a drill trick. The oil (15-50 wt) was obviously "cold" and there was definitely some resistance as the pump picked up oil - but not nearly enough to break off a steel thrust flange.

That said, it was in the 70's and I suppose if it was -20, the loads could be significant. The ball bearings I installed were not the deep groove type so they are not made for thrust - the good news is that there are two of them. Hopefully they will hold up.

If you spun the oil pump with a drill the vac pump was not driving. That is where the force comes from.

[fatmobile]

 The I-shafts I've found with a broken thrust flanges all had a timing belt riding off the outer edge of the sprocket.
  The belt rides to the outside, the crank sprocket pulls it back to the inside.
 This happens while it is being dragged across the intermediate shaft pully.
 I believe that the gears shove it outward and the belt shoves it back inward as it's dragged across it.
 This slaming against the thrust surface is what breaks it.

[Toby]

Not a chance. Those forces are pretty small. It is from somebody beating on it with a hammer, or some similar trauma. FYI the oil mpump load is vastly larger than any vacuum pump load.

[theman53]

what I was referring to is that if the guy was spinning the oil pump with a drill then the IM shaft was not in there. If it wasn't there then the gear wouldn't be sending it to the thrust surface. Now if he drove the oil pump with the IM shaft installed and somehow held it all in place then that is different.

FWIW I think some break from someone prying on the pulley to get the pulley off. I have only had one that was broken, but the IM pulley was eaten up by a screwdriver, so that is where I get my theory.
