Garlic and shallots

The larger ones hung individually are the main crop (hard and soft necked). The bundled small bulbed ones are volunteers from another part of garden. The volunteers are nice tasting purple hard necks we planted years ago. Next season we will give some of them a better chance.

Some shallots hanging up there too.

Trip – Nitinat and Klanawa

A few days exploring the Klanawa river watershed, this general area – from Nitinat falls on the upper right, to Blue Lake on the lower left.

First night spent on Nitinat river, near the falls. It was raining on and off, plus their were other campers 300 metres downriver, we headed off next morning to find a better spot.

We had brought along the GoPro Hero 2 cam, and the only even close to worthwhile vid we shot was this less than exciting “vanagon in puddle” sequence on the road out of the campsite.

We headed northwest, over into the Klanawa watershed, and followed the river downstream. We stopped here and there, looking for a nice spot. An example of a side track – grey skies but it was mild and not raining.

My son trying “logging parkour”.

And at last we found a spot, secluded lake, not logged.

Nice big bear poop close by.

Next day was sunny.

And off we went again, further west, looking for a spot on the Klanawa river  and no, we didn’t want to camp under the bridge. We did swing past the spot on the Tsucowis that we camped at 2 years ago, but it was occupied. We went part way around Darling main loop, and took one spur that led down through an old (1960’s?) logged area and found a skidder. I’m thinking that someone took it down there to salvage cedar logs for shake block cutting.

We didn’t find any nice spots, so back east to the bridge across Klanawa and then west again on south side of river. Finally found an OK spot west of Blue lake. Slash camping again, but a nice view.

Plenty signs of elk.

And bear, of course. Dogs are tired out.

As the sun went down, the marine cloud formed. That’s the west coast trail way down there in the cloud.

The moon was pretty, sky red with smoke from Russian and Alaskan fires?

The lads slept in the tent that night.

Nice sunny morning.

After breakfast we packed up and made a concerted effort to find a trail down to the Klanawa. Some false leads and a lot of bushwhacking later, we got there.

It was a lovely spot, virgin forest and clear water. At five pm we headed back to van, and then home. Van ran fine, but we were heavily loaded and the stock tintop syncro springs are not stiff enough for this sort of thing. Perhaps my old ’82 westy springs might be installed in the front and coil over shocks to help the rear?

Vanagon – syncro front spring removal without spring compressor

The other day while replacing the upper control arm bushings on the van I wondered if the spring could be removed without using a spring compressor (Bentley shows compressor being used). I asked on the Yahoo syncro group and a couple of listmembers said it could be done, and they have done it. So today I had a go at it, and at the same time try out the spring spacer I made.

I have to warn you, while this procedure does not expose you to the same dangers as using a compressor , there are dangers to life and limb. That might sound like hyperbole but it isn’t. Please take care if you do what I am about to describe, take it slow, think, be cautious.

Also, what will be described was done on a van with stock springs and with a modest spring spacer. I do not think that it will work with longer springs or thick spacers.

Ok, on with the show. Van jacked up and supported by some solid 8X8 shorts, wheel off, sway bar drop link disconnected, radius rod/arm removed (inner adjusting nut not moved). The lower shock bolt loosened (22 mm socket).

Upper ball joint disconnected, those 2 socket cap bolts.

At this point I was not sure how this was all going to work, seemed like the spring perch would hit drive shaft.

Plastic cap removed from shock shaft end, 17 mm nut loosened but not removed.

Bottle jack supporting shock through hole in lower control arm.

Shock bolt was driven out easily.

And look at how clean that bolt is. I’m lucky, while I have some nasty rust on body, most if not all of the “mechanicals” are in great shape.

When the bolt was driven out and the bottle jack released, the lower control arm fell down. I did not expect this, of course in hindsight I should have.

The 17 mm nut was removed from top of shock and then shock and spring fell out.

Slight digression here, comparing the orange spring (2 white stripe code) from my ’82 diesel westy with the newly removed syncro spring. 20 mm difference between them. Confirms IG16 Wiki data.

And what do you know? The spring pads are different after all. Same part number (although writing this now I recall the syncro spring pad part number has an “A” suffix).

Shock fully extended with syncro spring.

Shock fully extended with orange spring. I would say a shock shaft extension would be need to use this spring in the syncro.

Side by side comparison.

I had to make some slight adjustment to the collar of my spring pad spacer to make it fit the syncro spring pad. Needed to reduce collar diameter a few millimetres

My T-handled tool in through access hole under seat to engage and guide shock shaft up through hole in shock tower.

The shock spring combo needed to be drawn inward to allow shock shaft to go up through hole in tower. I used a ratchet strap.

Here it comes, I’m using the bottle jack to push against the bottom of the shock. Lower shock bolt is installed.

You have to guide the shaft so that the step on the shaft does not get caught on edge of hole.

There you go, installed with spacer. You can see “shadow” line on spring pad that shows how much was in tower without the spacer. I did not re-attach sway bar or radius rod, but did put on wheel and drop van to ground. I bounced van as best I could and measured hub to fender distance. It looks like the spacer did the trick, now 19.25″ at front, 19.125″ at rear. Very preliminary measurement, probably will be a little different after driving.

So then I took it all apart again and removed spacer. I only have one spacer made, but the exercise was worthwhile – I can remove spring without a compressor and I refined my spacer to fit right.

And a bonus, I think I found my pesky squeak – it might be the bushing between sway bar drop link and the sway bar. I had made my own bushings from polyurethane skate board wheels, I greased them during this work and now squeak is gone.

Vanagon – syncro front spring pad

I think I mentioned in my post about upper control arm bushings that I was considering further tomfoolery with the front suspension. What I have in mind is a modest front ride height increase – 1″ at the most – to compensate for the weight that the camperisation added to the original tin top. Currently I have approx. 19″ from wheel centre to fender edge on the rear (one extra stock spacer above rear spring) and 18″ from wheel centre to fender at the front. You probably know all the approaches to ride height adjustment, and no doubt have your preferences. I’m going to have a go making some spring pad spacers, similar (but not identical to) what Futbus in the UK sells.

I discovered that the spring pad is the same for both 2WD and syncro, so I could make a spacer to fit the 2WD stuff I have on hand. Here is the spring pad, underside that fits onto end of spring. Yup, that orange paint is there again. BTW, the spring (from ’82 westy diesel)  had 2 white paint marks in middle of coils. The closest match I have found is the 2 beige mark one listed on the IG16 Wiki page about springs here. Do you get the idea that I am tempted to try these spring out on my syncro despite the 20 mm or so longer length? I am, but I want to have springs side by side on bench to confirm length differences. IG16 chart says it’s 20 mm diff, and that would translate to a 33 mm ride height increase (all things equal, ie spring rate). That is a tad more than I am shooting for, but so close as to worth trying.

Oh BTW, “x” amount of lift at spring translates to approx. 1.66 “x” at wheel. Slightly different multiplier at rear. The IG16 Wiki explains more.

You can see how the spring fits into spacer and the remnants of the tape that holds spring to spacer during installation.

So back to the additional spacer idea. I had this doughnut shaped bit of aluminium, was going to make some other goofy thing out of it, but never did.

I wish it was thicker stock so that I could have had a longer collar.

As is, I made the spacer 16.75 mm thick, and the collar 8 mm. The stock was originally nominal 1″ thick. I made a little bit of an effort to radius the top  corner to mimic the stock rubber pad.

And the rubber pad pushed onto the collar of the aluminium spacer. This pic could be a little confusing, there is an aluminium disc under the spacer, more salvaged scrap.

Whoa! There’s that orange spring.

Pad and spacer on spring.

I probably will use some adhesive between the pad and the spacer. Seeing as I am just trying to bring ride height back close to stock tin top specs, I don’t think I will need to extend the shock shaft at threaded end. More on this to come later.

Vanagon – syncro – VW tool 3141 substitute

As I am planning on fiddling around with my syncro’s front springs and shocks I thought I might need a tool to guide the top of the shock back into position when re-installing. Bentley calls for VW tool 3141, the best pic I could find with a quick search is this Snap-On one. I had some 1/2″ diameter aluminium rod handy, and a M10 X 1.00 tap (same thread as used in pressure sender on engine, I needed one to make my sender relocation manifold). The lathe made making the tool easy, shaft is a press fit into handle and is pretty secure, but I probably still need to blob on a bit of weld on the joint.

End of shaft.

End of old 2WD front shock – it has the same thread.

Tool screwed onto end of shock.

I hope to be able to show you how it is used when I pull the front springs from the van, but I need to borrow a spring compressor before I get going with that.

Vanagon – syncro upper control arm bushing replacement

So on our last trip I noticed a squeaking when suspension moved, noise coming from front driver’s side. I suspected upper control arm bushing so I set about replacing them on that side. It is a pretty straight forward job, and here are a couple of diagrams illustrating where the bushings are.

I jacked up and supported driver’s side front of van and removed wheel. When I detached the upper ball joint I could move the control arm by hand, and the squeak was there. 19 mm nut on one end of camber adjusting bolt, other end is 14 mm socket. Arm off and in the workshop.

Close up of one bushing.

Other side of bushing. There is a good chance these are originals.

Here is one of the new bushings. Vaico brand, I don’t know where they fall in the quality line up, but I got them in trade for some used vanagon parts. There is a great Samba thread on UCA bushings here.

I wondered if an O-ring would help keep any grease in.

Then I tried some silicone over the O-ring, a variation of what Tencentlife did in above mentioned Samba thread. I ended up removing the silicone and adding a second O-ring.

Now getting the old bushings out. I don’t have a press so I used a bit of aluminium tubing, a biggish socket, and an old 2WD control arm bolt, and a heavy hammer to drive the bushing out.

Look at that clutter. Workshop is in a real sorry state.

Old bushing out.

Bore of UCA where bushing fits. On the syncro it is a simple press fit, no spot weld needed.

Using a vice to press new bushing in.

Part way in. Ok, you’ve noticed that I painted the UCA. A very casual crap job and wasn’t needed (original paint still good), but I had a can of orange paint and I thought it might look cool. Overnight drying time was not enough, paint still soft, came off here and there. Perhaps I should lock up the paint.

A bit of pop can in UCA to keep a large socket in place while bushing driven home.

And the other bushing pressed in.

Out at the van, rear of support where bolt goes through and eccentric washer sits.

Front of support.

Rear eccentric washer in place. It was a fiddly job offering up the UCA into correct position and not have the washers fall out.

But in it went finally. Everything re-assembled. Guess what? I still have a squeak!

Next post will deal with camber adjustment and perhaps finding the squeak.
