Rocker Cover Screws, Which screws on the underside? Options

[Arno914]

Hello,

on my 1971/-4 I recently cleaned and resprayed the rocker covers.
On the top I have the correct hardware to attach them, plastic rivets and screws with spacers on each end under the fender lips.

In the bottom part, there are three large holes in the covers, apparently for M6 (?) size bolts (3 each side).
On my car however, there where 3 holes randomly drilled to attach the covers with small sheet metal screws. Seems to be "original". The fit is correct.

Question: Did the factory attach the underside of the covers this way? On the early cars maybe? Are there nuts in the longs for larger screws on "later" cars? (Mine doesn´t have them.

I added rubber spacers to help drain water and dirt upon reassembly.

Greetings, Arno

don't know whats going on there.
the big holes are the factory locations.
factory used 6mm panhead screws (small bolts really with screw heads).
been thirty years since i took mine off to clean in there.
can't really remember whats in the longs but whatever it is it takes those M6 pan heads.
mine is a 74.

can't see why earlier cars would be any different.
i looked in the factory workshop manual before posting this to check.
it just shows the three panheads as per my car.

think that must be some previous owner mod.

Sure isn't factory.

Thanks for checking into this. I double checked with my factory manual and it says "3 Phillips screws on the bottom". Probably there was a change towards M6 on the later models? My ´71 doesn´t have M6 threads on the bottom of the longs. Maybe my covers are from a later model?
Not that this is soo important, I was just wondering... (IMG:style_emoticons/default/dry.gif)

@Arno914

yes - my factory manual in english has the same generic description of 3 phillips heads.

the PET lists and specs them.



PET lists two washers which the factory shop manual doesn't describe.
6,4 washer and a 6,4 J shakeproof washer (toothed washers).

someone with an early car could tell you if different to later cars.
later cars match PET.

Thank you, wonkipop!

We will drive to England next weekend (1.000km/600mls one way) to attend the big 914 meet. I will for shure check out other early 914´s... (IMG:style_emoticons/default/biggrin.gif)

The PET lists ‘pan head screws’ for the side valences, the same part number used for some of the type 4 engine tin; they were slotted cheeseheads. I’ve seen a number of hardware bits that use the original part numbers which are visibly different but functionality equivalent.

My car had a combination of cheesehead screws, hex bolts, and a wood screw. It’s apart at the moment, but it’s going back together with cheeseheads.

My best guess (as it happened to mine), the original rocker hole got rusted and screw wouldn't hold. PO drilled new hole into sounder metal.
Those Phillips head screws were awful to remove. I filled in all the holes with metal epoxy, sanded/painted, and redrilled to an M6 Hex screw (yellow zinc) and washer. MUCH easier to remove & reinsert.

Make sure you don't put any holes in your heater tubes.

Change to hex head screws. I used stainless.
