Tech Tips, Repair that VW!!
|
|
All of these are things that I have done, I have actually rebuilt
the whole VW engine and car. My VW was down to it's shell, no dash,
seats, carpet, headliner, engine, wheels, tires, exhaust, rear axel,
gas tank, etc. I was planning on writing about the whole process but
the film I was given had already been used! All of the pictures
where messed up and I never got around to writing it without the
pictures. So here is what you do get, a few short tips to help you
on your way to VW domination.

Timing Belt
|
|
This procedure is for the 1.6L, 1.7L and I think the 1.8L is also
the same. You will need to remove the timing belt covers and then
crank the engine over until the timing marks on the flywheel and the
engine side of of the transmission line up, the mark on the flywheel
should be a "0" and the mark on the engine side should be
a ">", together they should look something like this
">0" when looking from the passengers side fender.
To crank the engine over you will need to use a 19 mm socket on
the crankshaft bolt and then rotate it until these marks line up.
Next you will need to look at all of the timing gears and make sure
you know where all off the dimples are on each one because they will
all have to be in the same spot when you put everything back
together. There are two timing marks (dimples) on the camshaft gear
you only need to worry about the one on the valve cover side of the
gear. There is a notch on the crankshaft pulley and one on the
intermediate shaft gear this dimple should line up with the notch on
the crankshaft pulley, If these two marks are not lined up properly
then the distributor will not be in the correct location, Next
loosen the timing belt tensioner, I use an adjustable wrench for the
big nut and a 15 mm wrench for the smaller nut. Next take off the
accessory belt then take off the water pump pulley. When you put the
belt back on make sure that all of the timing marks are lined up,
and when you tighten the belt the front side of the belt should be
tensioned then tighten the tensioner clockwise and tighten the nut
clockwise. I have only done this on cars w/o a/c.
Good luck.

Running Rough
|
|
These are some things that may be causing your car to run rough.
- Ignition timing may be off. Check spark plugs, cap and rotor,
spark plug leads, check to see if timing belt has slipped a
tooth. Also check all vacuum hoses and look for any loose wires,
especially on or around the distributor or coil.
- Check all connections between the air box and throttle body,
look for rips and check hose clamps ext. If these are
disconnected your car will run like crap.
- The problem may also be a bad fuel injector, bad air fuel
mixture or incorrectly set idle.
Good Luck.

Rear pivot bushing
|
|
These are simple. To remove these a puller would be your best bet
but you can do it with the following tools a 15 mm socket (may be
different on other cars) a pair of channel lock pliers (preferably
with a warranty) and a hammer, A propane torch may help, . First
take off the "U" shaped bracket that holds the bushing to
the car, Now make a mental note of the position of the bushing so
you can put on the new one the same way.
Next put the channel lock pliers beside the biggest side of the
bushing, there is only one logical spot to do this, you will know
what I mean when you see it. Now hammer on the side of the pliers
until the old bushing comes off (Bushings may need to be heated with
a torch, mine did not, my friends did). Now put the new one on with
the hammer, you may want to spray silicone on the inside of the
bushing.
Good Luck.

Back up lights
|
|
I had this problem with my 82 Rabbit. It was the reverse
light control switch. It is on the transmission beside the
transmission mount on the manual rabbits, not sure about the
automatics. There should be two wires connected to it, if so take
them off, If not that may be your problem. To get to the switch open
up the hood and look to the right. you should see the transmission,
find the transmission mount and look to the left of it, the mount
has four bolts that bolt to the transmission and it is shaped like
an "L". There should be a switch that has two wires on it,
There may be a rubber boot over them. Touch the two wire together
and if your reverse lights come on the it is a faulty switch. Use a
deep socket or a wrench on the switch, 17mm I think, take it out,
put in a new one, attach the wires and your done. simple and cheap!,
I read somewhere that they ware out faster if you have a short shift
kit.
Good luck.
PS. The switch coasts $9.95 at Bow-Wow auto parts here in
Vancouver. They have a web site you can order from. Prices may
change.

Front wheel bearings
|
|
These are pretty easy compared to what I thought it would be
like! Yes at first I thought that this would be a hard job to do on
my own. Everything that I read said that you need a special tool to
do the job, and yes the tool would make it a lot easier to do but it
is not needed. In fact I had access to the tool but was unable to
get it when I wanted it so I made do with what I had.
All I used was a vise (6") some 3/4" drive sockets a
hammer a pair of snap ring pliers for the circlips (You could use a
pair of needle nose pliers) and a puller, it went smoothly.
First I took off the wheel bearing housing, then I placed the
housing in a vise so that I was looking at the side of the assembly
that the tie rod end, ball joint and strut attached to, I then
hammered out the hub with a big socket. Next I
removed the two circlips that keep the bearing centered in the
housing. The next thing I did was used another big socket to hammer
out the bearing from the housing. I put a circlip back in and
flipped the housing over and hammered in the new bearing (Only
hammer on the outer race at this point) with a socket until I could
fit in the other circlip. I still had to remove the inner race from
the hub for this I used a puller (you could use a chisel to knock it
out but it would be more difficult) Then last but not least I
hammered the housing onto the hub with yet again another big socket,
to do this I put the hub on the work bench, floor, ect. so that the
side of the hub you see when you take off your tire is facing down
then I centered the housing over the hub and proceeded to hammer on
the inner race until the hub was completely in the bearing. I then
put it back on the car.
I hope this helps someone who does not have the money to get this
done.
When I do my other bearing I will try to take pictures. (This
won't happen now, since I don't have the car)
*** NOTE ***
I have had e-mails about this method, both good and bad, Everyone
agrees that it works but some argue that the hammering is not good
for the bearing. With this I agree, but you make do with what you
have and as long as you are careful it should be ok for years. It's
up to you. I take no responsibility if it does not work for you. As
with anything I say on this page.
