Short story, made a rivet from stainless rod. One end with shoulder, the other end with hole ( to make that end easier to flare).
Worked really well. But I think it’s unnecessary work. Both friend and I had the same idea of finding Chicago screws that will do the job. And those screws are out there.
Funny thing they are called M5 Chicago screws, but the actual screw portion is M3. Pictures show better. Oh and you’d have to trim the length a tad. Is brass hard wearing and strong enough? I think so.
Back to my rivet. Here’s a sequence of pics using another old wiper arm. First couple show how you can hold the “c” connector in a vise and pull back on the arm to release hub. Head of the stock rivet drilled out and punched thru. Stock rivet 50 microns larger diameter than the Chicago screw… yadda yadda yadda…you get the idea.
A few posts ago I wrote how I took apart my spare wiper arms for powdercoat. The hinge between the arm and the hub was a steel rivet, had to drill that out. So what to do about reassembly?
Tried something this afternoon. Yeah, perhaps an over thought idea. Turned down some stainless rod to around 4.8mm, with a poofteenth narrower shoulder on each end ( the arm holes are smaller than the hub hole. Maybe it’s the paint.)
Tapped each end M3. I have some plastic pan head M3 machine screws, I’ll get some black stainless versions if I decide this is a good method. What gives me pause is I have to bend the wings of the arm apart to get the shouldered hinge pin, in the hub, inserted into arm. It’s kludgey.
But looks ok, arm moves nicely too.
I found this table online and I apologize for forgetting where, I’d like to be able to credit the source. I think there have been posts on the Samba with the same info.
In any case, the VW is used in Bentley procedures to test fuel and temp gauges.
David B. commented:
The Vanagon gauges are electrically the same except for the blinker circuit in the temp gauge.
Gauge resistance ~52R, input voltage ten volts plus/minus a half for tolerance of +/- half a needle width.
Top mark ~35R (fuel full or temp ~130C)
Temp blinker starts ~45R (~125C)
100C touching high side of LED ~82R (OE sender)
90C touching low side of LED ~106R (OE sender)
Top of reserve ~170R (adopted in later models as the calibration low point instead of bottom of the gauge)
60C/empty/bottom mark on gauge ~265R
Originals were a bit ratty, and a couple wouldn’t stay put. Made a set from black Delrin. You 3D printing folk have an advantage over us subtractive makers 🙂
Ok, bear with me, trying a link to the fusion 360 file, might take a few tries. Grrr, trying to insert model into a frame here, dint have the skill. This link though will take you to model and I think you can download.
Hold on, managed to have a zipped file of the fusion model, to download without going thru fusion’s meat grinder.
p for inconsequential
You must have seen these around. All the usual suspects sell them and I went for one last summer.
Around 30 bucks, worth the gamble.
It has a wee solar panel and function buttons on top of it and a micro USB port on one side ( kit comes with short micro to standard usb cable). There is a sticky type gel pad on the bottom to keep it in place on your dash, and that works well.
The solar panel keeps the unit charged up, mostly, after an initial charge via USB. I say mostly as the panel couldn’t manage to eek out enough current during a one week period in December. Weather was very dull, days were short.
Buttons on top of unit for setting things up. You can have low and high pressure alarm limits, and low temp alarm. Alarm is beeping and display flashing. The display changes from off to on when it feels movement , ie when I open the drivers door to get in.
The pressure and temp senders replace the tire valve caps. There is an additional locking nut supplied for each sender thats supposed to hinder theft and loosening. Of the senders that is, not the van.
The senders connect to the base unit with no fuss, and I haven’t had any disconnects between the two. Each sender has a button cell powering it, I haven’t replaced any yet. I thought the senders stuck out from wheel more than I’d like, but I haven’t knocked one off yet.
For the first while I was obsessed by watching the pressure and temp during trips. I wanted to see if there were any temperature differences between front and rear wheels during braking on long descents. Maybe I saw a 5-10 degree difference sometimes, but as the senders are sticking out in the airstream I’d say it’s not a good way of monitoring brake temps, but you do find out which side of the parked van the sun is shining on 🙂
All in all I’m pretty pleased with it . It sits on the dash, drivers side corner, not too obtrusive and getting some light for the solar panel.
Last summer my tower started to leak. Everyone knows the plastic distribution tower / manifold weakens with age. The 2 wd tower is different in size and shape but same thing happens to it.
What I posted to the vanagon mailing list:
A few months ago I swapped in an aluminum version of the stock plastic coolant distribution manifold. The 2wd and Syncro versions differ in shape but not in function.
I’d always wanted to do this but what got me off my duff was my manifold had the additional feature of a temp sensor plug in one end. This is for the optional webasto aux heater that warms the coolant and thus the heater box. It was fairly common on Canadian spec Syncro.
The temp sensor is very much like a temp II sensor in that it’s a push in device with an o ring and retaining clip.
The o ring on mine failed and leaked coolant. Temp fix was new o ring. The better fix was the aluminum manifold which was easier and less messy to install than I feared.
Bottom line is, if you have the webasto aux heater in the engine compartment of your Syncro, or if you had one and forgot about the temp sensor , check the sensor O ring.
Another example of idle hands. I think it was from model year 85 on where ther parking brake cover was changed from a vinyl boot thing to a hard plastic shield. And on my 86 Syncro it’s the brown plastic. The brown plastic that does not age gracefully. So one Saturday last summer I took some thin leather, got it a bit damp, and glued it to the plastic. It looks fine, some little wrinkles at the hard curves, but acceptable. Have not yet figured out how to cover the actual handle.
