Had a few minutes after work to do something on the bus...thought I would modify the Tach so it will work with the Subaru engine. The original engine uses a different signal to the Tach than the Subaru so the Tach won't work without a couple modifications.

First up...remove the instrument cluster.

Then carefully remove the Tach assy.

This is what were after...the circuit board on the back of the Tach. To make the Tach work with the Subaru you need to remove the 3.32K Resistor out of the circuit and then replace the 1K resistor with a 1/2 Watt 220K Resistor.

Parts removed and ready to solder in the new resistor.

And the new resistor soldered in place.

Now it's just re-assembly time and you have a working Tach.

The instrument cluster is made from a plastic that gets very brittle with age, even though I was careful there were several small areas that had formed cracks around the screws. I repaired the cracks with a two part plastic epoxy and will let it cure for 24hrs before re-assembling the dash.

Ok now that's cool!!!! I've got to book mark this page for sure. I'm hoping to use the Subaru cluster eventually but would like to get the beast on the road ASAP! Or so says my wife ... Get it out of the garage or I'm having a garage sale! I digress ... Looks like a fix even I could do! Shocked Shocked
Thanks for posting that!

Cheers,
Mike

On one of my conversions I did that mod, the other got a 7k tach out of a jetta. The jetta tach has a small barely noticeable gap at the bottom but I like that one better since the needle sweep doesn't go all the way across to the far end of the gauge when reaching redline and it is a little easier to see. It is also plug and play.
Just another option. Wink

It's looking really good!

What kind of oven are you using to powder coat? Seems like you've done some pretty big stuff, like that spare tire cover.

The oven I've been using is just big enough to do a rear trailing arm...I had the tire cover done at a local shop Smile

Thanks for the heads up...sounds like a good option. Might have to keep an eye out for one Smile

Did you use an OBDII scan-gauge or software to measure RPM as well, and see if things are calibrated correctly?

Very nice job indeed Cool

It looks like your original tacho was of a diesel vanagon,looking at the green RPM range.Where did you get it from in the US...?

Not a diesel, that's a regular US model WBXer equipped Tach. Technically a '86+ tach if you had to make the mod. For whatever reason, '85 tachs work fine.

Lots of work today...not a lot of pictures.

Installed Hushmat in the rear of the bus this morning.

Image may have been reduced in size. Click image to view fullscreen.



Installed the transmission vent line, I forgot to install it when the trans was out. If you are installing a Syncro trans install the vent line before re-installing the trans, it's a real pain to install afterwards! Packed and installed the passenger side rear axle, adjusted the pass side rear brake, cleaned the coolant overflow tank and filled it with coolant, checked alignment on the engine carrier and torqued all bolts, and I'm sure some other things I'm forgetting.

It's finally ready to be driven on a test drive! Smile.....BUT.....To get it out I need to install the bare rims again to clear the garage door. First up remove the big brake calipers and rotors, I'll just hang the rotor for now out of the way with a wire. Jacked up the front end, removed the pass side tire and brakes and went to mount up the 14" wheel....BUT I can't find the lug nuts for the steel wheels anywhere! The ones from the aluminum wheels won't work. Sooooooo the bus will spend one more night in the garage, I'll borrow a set from the friend Mike in the am. Test drive tomorrow!

Jacked up and waiting for lug nuts.

Had the garage door partially opened today and the sun was shining through the rear rack...thought the shadow looked pretty cool.

More Tomorrow.

Ok...up early and ready to get this baby out of the garage. My friend Mike stopped by to help roll it out, with some sleep we finally realized the reason our lug nuts weren't working...without the rotor installed on the front the studs stick out to far and allow the nuts to bottom out, when we rolled the bus in the garage it still had the factory rotor on it as a spacer.

Soooo we just added washers on the studs to take the place of the rotor...and the wheels were quickly bolted up.

Finally outside!

Bleeding the coolant system.

A quick test drive to Mikes house, checked the OBD2 system, no codes Smile There is a hunting of the throttle at idle before it gets fully up to temp, it comes and goes and if left alone gets worse and worse. The fuel trim was around positive 3, I'll check into it further.

Image may have been reduced in size. Click image to view fullscreen.



Getting hot outside and not being able to roll the passenger window down just isn't going to cut it. I removed the passenger power window reg and installed a manual reg like the one on the drivers side...much better Smile (I know I know don't remove the power windows....but I actually prefer the manual windows in the bus).

Image may have been reduced in size. Click image to view fullscreen.



Did about 60 miles around town today, everything is running really good. This evening I had a coolant leak develop on top of the surge tank at the O-ring where the coolant level switch screws in. I tightened it up some more and it seems to have stopped leaking. I'll wash the engine bay down tomorrow and clean the coolant off the exhaust, might pull the switch and replace the o-ring with a slightly larger one. I'll keep a close eye on it for sure...not sure I trust the quality of the aftermarket surge tank yet.

Here's a few random crappy I-phone pics taken on the test drive around town today.

Feels great to be driving it again! Still a few more mods to come, gotta get it ready for camping season now Smile
