The old 1,6 CS diesel was a bit to slow in hills/highways (to the point it get dangerous in traffic). So it needed to go. I don’t going to race Lemans with the bus, I just want a more modern, stronger, cheap to drive (diesel) and most important RELIABLE engine that always work. First I was looking at a AAZ 1,6/9 Turbo engine but with a turbo it’s just another thing that can brake and these engines always runs much hotter. So I decided to go with a VAG 1,9 AEF engine, found in VW Polo, Golf, Audi and Skoda Felicia.
THE NEW ENGINE
I managed to find a really lowmilage 1,9 AEF diesel engine from a Skoda Felicia, year 2000. But it is not just to bolt this engine in the bus and drive, a lot of stuff need to be changed and parts from the 1,6 CS need to be re-used and modified. But its probably the easiest conversion you can choose, if your thinking of using a non standard engine in your VW T3 diesel bus.
While the engine is out I will also take out the transmission. And make a check up, change shifter couplings, linkage bushings and gaskets. Upgrade driveshafts to stronger, Porsche. Upgrade the differential with a difflock from Weddle Ind. In a standard “open” differential, torque is divided equally between the wheels. If one wheel slips and spins, only a fraction of the torque is utilized. The difflock eliminates this problem. Power will always be delivered to the wheel with the most traction to keep you moving instead of getting stuck, up to 100%. Then it we can do some serious off-roading 🙂
Have been working on the camping interior lately. The old interior was crappy and looked like shit, it had some structure wall weave/papper that hade been rolled with paint 10 times, the touch and feel was like a 40 grit sandpaper so it needed to go. But it was a good design/plan layout on the cabinets and storage. So I decided to keep the base of it and make a new outside finish on it in light grey oak vinyl.
All cabinet doors was made new in 12mm Medium Density Fibreboard and painted in medium gloss grey with paintgun. Countertop was made new in black colored MDF with semi-gloss clear coat, now with space for a portable kitchen / stove. Above the stove space I made a 12v kitchenfan with outlet, the fan is moving 3,8 squaremeters of air per minute so now you can make bacon with closed doors without smoke/smelling anything 😉
All the old gas equipment was removed, and the old fridge was replaced with a modern 12v Waeco 48L fridge with freezer. A new black sink and a new Reimo water tap was mounted. And all new waterlines, pump and 20L freshwatertank. Before the water ran straight out on the ground, now it goes into a 10L tank first, with a valve so the water can be emptyed. This is good of you are using water when you are on a parkinglot, ferry or on a big camping with neighbors.
The new heater is now installed and incorporated with the old heater system design on the Highroof bus. Easiest and fastest way to install this would be to just place it under one of the sofas inside the bus and pull the heater hose out. But I decided to complicate it a little more but in the end with a much better result I believe. My bus had the Eberspacher heater M-code from factory so my idea is to remove the old heater and replace it with a new modern diesel heater.
Doing it this way, I will get a modern reliable diesel non explosive/safer heater than the old which ran on petrol. I will automatically get digital display with timer, remote start, thermostat control and much more. I will not loose space or hear the noise from it (like if it was installed inside the bus) because the heater will now be outside under the middle floor (inside the protective splashpan) where the old factory heater was mounted. I will now get heat not only in the rear of the bus but also in front cab and windshield ect. I will also add some extra airflaps in the heaterchannel so I can adjust the heat to only front or back to the rear floor, bed and top bunk. I will then insulate all pipes with aluminum air bubble foil to protect the heat from the cold surrounding. More work doing it like this but I think it will be all worth it in the end.
I started by removing the old crusty Eberspacher BA6 heater that was mounted in the center under the floor, mounted a new 90mm center pipe under floor instead (like on a ordinary Baywindow without the BA6 heater option). The new parking heater was the installed on the side of the new center pipe. It was a really tight fit, the height of the heater is 140mm and the space under floor was 145mm. I had to cut a 3-40mm notch out in one of the floor supports to make it even possible. The heater exhaust was wrapped in “header wrap” for less heat radiation and was routed out back to a muffler and then out in front of the left rear wheel. You don’t want to route the exhaust fumes out on the sliding door side of course! The fuel pump was mounted in a rubber holder in 40 degree angle on the frame of the bus, filter was put on outside for easier change in future. The air intake for the combustion chamber was routed back (don’t place it against wind/driving direction) and a filter bolted in the end. The air inlet to the heater fan is hooked up to the stock inlet pipe (from a hole under the rear rock n roll sofa). This means it will circulate warmer and warmer air, and don’t have to warm it up from ice cold outside air all the time. It will make it produce more heat too. The heater outlet is connected to a air flap (where I can choose where I want the hot air, front cabin or rear. I also made a extra heat pipe for the rear bed and top bunk, so you can feel the heat directly in the bed when you turn it on in the morning. 🙂 You can see the heat outlet in top bunk on the last picture. Stock is only rear floor otherwise. The small 10 liters diesel tank will be mounted under or behind the front passenger seat, this way you can easily see when it’s time to refill. It consumes only between 0,19-0,5 liters per hour. So on one tank it can run on full blast for about 20-24 hours before it time to fill it up again. Insulated all pipes from back/rear of the engine to all the way to the front cabin. Still have some electric wiring left to do before it all done. Can’t wait to test this beauty out!!
Lots of work have been done lately on the VW Baywindow Highroof! Whole roof have been finished in California White color. All doors and lids have been painted on the insides and then fitted back on the body. All panels are now sanded in 800grit and ready for toppaint in VW L20a Marino Yellow!
It is time to get this beast out on the road again! A 1961 Monark Monarscoot with a 2 speed Ilo Piano engine. It was found and digged up in the forest/woods 15 years ago and have since then been resting in my garage. Still sporting cool old SpeedRiders stickers from back in the day (1998-ish). Needs lots of love, as picture shows, basicly everything is shot and need to be replaced with new parts.
Plan is to make it a ratlooker with a updated drivetrain with more performance. 🙂 Stay tuned for more updates, this is going to be a quick build, needs to be done before the spring, so its ready for all the mopedrallys this summer. Will be a fun ride!
Have not got very much done lately. As my first son (1 year old) takes most of the time now. So that more important at the moment. But Im trying to push forward on the bus too, couple of hours after work and on weekends etc. Soon have all doors and lids in primer and then it all just needs a easy sanding and then its time for a paintjob! Have also sandblasted the fueltank cover and bellypan and got them painted and ready too. Hope to start rebuild of the 1800cc Type 4 engine in begining of February also!
More to come, but thats it for now, here is some pics…
Blasted and epoxyprimer, ready for topcoat in VW factory greyish
Baremetal then yellow epoxy/zinc primer
Topcoat in VW L20a Marino Yellow with 2K polypaint with elastic characteristics. So the stones wont chip the paint. The gloss on the elastic is a little less, but this panel is under the car and you normaly never see it anyway.
After a weekend of work on the bus roof its now in primer! Finally. It needed a ton of work, was alot of gelcoat cracks that needed to be sorted. And the left rear corner of the roof had been hit earlier in the bus life and needed to be fixed up nicer. Will test fit a new Fiamma rooflight/ventilation and then I can continue with the bodywork on rest of the bus. Looking forward to paint! But still a long way and lots of hours left…
Here is some news on the build. Got the fuel tank installed today. With new fuelfiller neck, feeder hose, sender unit, tap and filter. Also replaced all rubber hose connections for the tank ventilation. Next time I will start bodywork on the huge roof…lots of fun…
Have been working on the transmission and driveshafts lately. Had a pile of new parts from Just Kampers waiting for it. The tranny was in very good shape and have been restored by VW (exchange parts) in the 1980s. But it still needed alot of work to look good again. Highpressure washed the case 3 times, to remove dirt and old oil. Drained the oil and it still looked nice (good sign)! Then 3 coats of paintremover was added so the black paint could be peeled off the case. Degreased it one more time, wirebrushed and sanded it making it ready for paint. A coat of primer for aluminium/etch was layed down and then 3 coats of 2K silvermetallic paint on top.
A new mainshaft oil seal was added, and both driveflange/shaft seals too. The nosecone got a new reamed bronze bushing and oilseal for the shiftleveler. Also the small plastic balljoint in the end of the shiftlever (the one that pushes gears) was replaced to a new made of steel, and will last a life time instead of a brittle plastic part that was before. The shiftrod feels very accurate and precise now, no more sloppy gearshifter! This is also a popular upgrade on VW race transmissions. Driveshafts and hubs was sandblasted and painted. New groundcable to chassi. New clutchwire. New gaskets, rubberboots and CV joints installed. New startermotor + bushing mounted too. New trans mounts upper and lower. And then the transmission was filled up with new fresh mineral API-5 grade transmission oil that VW recommended on these 002 cases. This oil is extra good to the special metalparts like syncro rings etc. Not aggressive like other grades can be to these old transmissions. Here is the pics…
Started to get the other side done, blasted, painted and new bearings and seals. Waiting on some new parts from JustKampers and hopefully I can put the bus back on its own wheels this weekend for first time in 6 months. Also fixed the rusted and dented up front floor cover, blasted and painted ready to be installed when all wires and brakes are fixed.
Have now started with the rear end of the bus, hope to soon have it rolling on wheels again, after 6 months in the air. Dismantled the rear IRS trailingarms, removed all old bearings and seals, cleaned it up and sandblasted everything. Then all parts was coated in zinc primer and the Deep black satin finish paint. All new wheelsbearings and seals pressed in, new bushings everywhere and also nuts/bolts. All new brakeparts and brakedrums too. One step closer…
Today the bus was dropped of at the glasshop for new front windscreen and installing all windows with new rubber seals. The last final parts (bumpers) are getting painted tomorow or on Thursday. They were handpainted with brush, twisted, rusty and lots of small dents. After sandblasting they got welded, straightned and all dents hammered out. Then a light coat of bodyfiller to make them straight again, then Zinc rustprimer and after this surfacer/ground primer to get them smooth again after the sandblasted surface. Next up is some more sanding and then Deepblack paint. New covers and bolts are waiting from Just Kampers! The bus should be ready for the road in the end of the week! More pics to come…
Time to sand the primer and fix small dents and scratches, and its alot of them both. When this is done a new coat of grey primer/filler is needed to get a good even base that needs a light sanding with 800 grit by hand before paint! Alot of work for sure!
All the places that have been sanded and sandblasted down to the bare metal have been painted with yellow 2k epoxy rust primer for protection. After this, all the small dents, scratches and imperfections in surface/metal after sandblasting etc have been filled up and sanded smooth and all the seams have been sealed up with new seamsealer. Then it was covered in yellow epoxyprimer again. When it was all dryed it just needed a light sanding before 3 coats of grey surfaceprimer was added. Now it has to dry a couple of days before it can be sanded down again, but this time more carefully and must be perfect! When this is done its ready for topcoat paint in VW Marsala Red H3H3.
Bumpers and some smaller parts is at the sandblasters at this moment and more new parts from Just Kampers in UK is on its way right now. Time to choose some cool wheels also, stay tuned for more pics and updates!
Stephans VW Bay project moves on and here is some pics from the transmission overhaul made last week here in the garage. The transmission is a 002 case, 3 rib from late 1973. Code CK. The Baywindow buses are famous for their poor gearshifts. If you have a sloppy gearstick on your bus, first check all bushings in the gearlinkage that runs thru the floor from front to back. If the shifting still is bad, then its possible that the gearleveler balljoint (made in plastic) inside the nosecone is worn out. I replaced this balljoint on this tranny for one made in metal instead, so it will last for ever! The magneticplugs was cleaned, oil drained, all gaskets and seals new and then a coat of fresh paint. Now its ready to be bolted back in the bus again.
Some updates! All windows are out, all rust is repaired and the body have been sanded. Now the body work can start and I hope to have it in primer next week. Then its ready for more sanding and smaller bodywork before topcoat goes on. Maybe VW Marsala red paint?
Got some stuff done on the front beam/axle on the Highroof bus this week. Fitted new grease zerks to the beam, installed a new center swivelpin and bushings, test fitted the new brakebooster, 4 new needlebearings (made a tool so they were easy to pull out). They were seated 8mm inside the tubes. Used a old bearing to knock them in again, and then the tool the last bit. New dustcovers mounted too. Got the axle bolted up in the frame on the bus and during the weekend, I will start installing torsionarms, spindles, tierods etc. The bus starts to look really nice, atleast underneath! 😉 More pics coming soon!
Been in Barcelona, Spain with the family on a vacation and just got back home. Nice to see some sun instead of snow! 🙂 Going to start put together the front beam axle this week. I have all the new parts from JUSTKAMPERS waiting for it, and hopefully have it bolted back up in the frame on the bus. More pics coming soon!
