|

They are readily available, both used and reproduction, over a wide range of years, conflicting opinions as to why they actually exist, and I rarely see them in a live motor.
I'm talking about generator [dust] covers.
The Bentley manual mentions them once, and suggests they may not always be present.
Are they to stop rain? Dust? Fuel? (All the above?). Do you need 1 or 2 (2 will restrict the air flow too much?)? Perhaps only used in sedans, and not convertibles? Maybe only used in certain climates? The forum threads I have read have been all over the place.
Does anyone have any ideas or evidence on their use? _________________ -Harry

I have gen covers on all of my engines. I have no idea why. They just appear to be factory correct.
Maybe they are a safety item. I know, I wouldn't want to get a finger caught in the gen while the engine is running.
Another thought may be safety related too. It might be to prevent a screw from being dropped into the gen and F-ing up the commutator.
It's kinda like the mystery surrounding the crank pulley shield. What's that for? Again, I have them on all of my engines because they appear to be factory correct. _________________ I have learned over the years.

IMO if you have a fuel leak and it gets into the cooling air for the generator. it is also a point of ignition for a fire from the brushes. _________________ Halfass Leatherworks*****GOT LEATHER Made to order Leather crafts, you can find us on that face book thing

Hmmm... perhaps they are more common for certain years/types? I generally am looking at 67 engines, and they don't seem to have them. _________________ -Harry

Only ever saw them on late cars with vented decklids without a rain tray. And there was only the one on top ... not needed on the bottom slot. _________________ Brian

Looks like a bolt, not a nut, on your generator spindle; not stock, correct? |

I'm thinking it's the extra silver washer installed between the nut and cone spacer combined with the angle the picture was taken. That washer will push the nut outward so it's flush or slightly past the end of the armature thread. _________________ 1960 Ragtop w/Semaphores "Inga" |

I can't speak to that - I grabbed that picture from the gallery. _________________ -Harry

If you click and enlarge, there is no sign of the shaft, which usually has a slight centering dimple. The nut/bolt hex is thicker than most I've seen. If the shims are used correctly, the shaft's threads should protrude slightly beyond the nut's threads.
Comparison:
It doesn't really matter, and certainly not to this thread, it just caught my eye and looked "wrong."

Aircooled from Heartland is Correct. I have owned my 67 for nigh onto 55 years now, didn't come with those covers (as it didn't come with the much lamented engine lock dust covers-because VW didn't send them out into the world with them). Checking with VW Parts manuals, one from early 1960's no generator covers, later manual from 1970's, no generator covers. if such a genuine VW part existed it would have been in the Parts Manuals and have a Part Number. A casual check of Owners manual doesn't reveal generator covers either. I don't recall seeing anything about generator covers in myriad Volkswagen bulletins perused many times. |

Not in Parts List/manual from early 1960' or 1970's, nor is it in VW Autobahn parts list from latter 1970's. Not in Reputable non VW sources such as "ROKA" or "Automotive Catalogs Inc 1969. Not on several Bosch rebuilt generators I have. Since the initial query was concerning 1967 I stand with Aircooled from heartland. Didn't have them! Volkswagen "E" Electrical workshop manual Part 1 (July 1970) in overhauling the generator doesn't show a dust cover nor discuss one. However, your Part Number does show up on Type 181 Parts Manual (111 903 531) as "Cover for carbon brush aperture" for generators 113 903 031 G and 031 P, 211 903 031 E and 031 D, 113 903 031 K. This manual is dated from April 1973 and indeed shows the cover in Illustrated Parts List. The Model 181 perhaps may be where the covers came into play with folks backdating their generators-but not as the 1967 Type 1 came from factory! |

My ‘68 Euro spec came fitted with what is often erroneously called the “67 year only” generator with push on generator terminals. It has been in the family since new and does not have the covers fitted. _________________ 1968 1500 RHD Lotus White Beetle since birth. In the hospital for major surgery
