Maybe I'll just do the vacuum pump hack then.
the 1.5 had the same setup.. bronze bushing and oil pump shaft were the only thing holding the gear and its thrusts..
and it worked for that engine..
honestly, i would look a "dizzy grizzy" from BBM.. dont think it will work without mods, but i know it can be made to work..

Does the 1.5 engine without a vacuum pump not use a fully splined oil pump shaft for the gear to sit on like the 16v petrol? If so then that design means the drive gear is fully supported and held concentric by the splined design.
But as I mentioned earlier in the thread.....
I have slid the oil pump shaft with the slot into the vacuum pump and there is play. Not just play in the slots due to wear, but play due to there being a difference in the OD of the shaft to the ID of the gear, so with the gear being cut off the pump there is no support on the upper side and nothing to hold it concentric, therefore I would be concerned the gear could move around and not mesh correctly with the corresponding gear on the end of the IM shaft.
The helical gear design means there is thrust trying to force the gear down, but also at 90deg to this as the teeth profile try to push it out of mesh unless the gear is held in a position it was designed to run in. Cutting the vacuum pump would really require the cut to be made above the clamped base so the shaft with the gear on is still supported. This would be complicated further as there is an oil feed up to the internal chamber of the vacuum pump.
I ended up just refitting the existing oil pump and vacuum pump today to allow me to get the engine running. If one of these rare gears turns up it only require the vacuum pump, sump and oil pump to be removed to convert it.

the 1.5 used an identical design as the 16v
Wonder if it might not be easier to have cryotreated and otherwise space-age coated the parts that wear to minimize it.
I've seen them wear too but not fail before a few other things were crapped out.
after reading this thread, seems like perhaps I'm the only person here to actually have in my garage a 1.6TD industrial engine.
it came with a little plug like the early 16V's used, but I can't vouch for it being identical. I would imagine the gears are cut the other way. I dont actually have that part any more unfortunately.
I gave that plug/gear away (well, i swapped it) since I had no use for it. The one I gave away ended up being used on an industrial 1.6D, as it turned out.
I recently discovered that I may have a 1.9 AAZ industrial engine. The rods are 150 mm long, the piston pins are 24 mm, and the pistons are about 6 mm shorter. Link to post
http://www.vwdiesel.net/forum/index.php?topic=32417.0I'm currently waiting for another block complete with pistons and rods from another member as finding OS "industrial" pistons has not turned out well (need to bore the block).
Don't know where it came from originally but I purchased the 82 westy in Northern CA and suspect it may have come from a forklift.

its the same pieces, but different sizes..
