[Vwdiesel] TDI weekend work-rear wiper

[James Hansen]

In your travels, look for a denso alternator.  It should be around the same
size as the one on your tractor, but around 55 amp.
Keep shaft speed in mind when you mount the vw ones- it's pretty high.  You
can hook the excite wire to batt, yes but better to be switched.
They will work fine being internally regulated, as long as they are working
well.  they just look for the right voltage, and output enough to make up
for shortfalls in voltage sensed.

Well, I finally got around to installing the rear wiper fix for the rear
wiper spray. My spray was following the wiper blade meaning it was on its
way out. I bought the kit to fix which keeps your OEM motor. At first the
things I had read stated it wasn't going to wipe the full 180 degrees. It
does. They may have changed kits at one time so it does. Hardest part was
getting the rear plastic off the hatch as they have some strong clips. It is
two screws and then you pull away from the hatch and they start poping. I
don't think I would want to do when cold for fear of breaking the tabs.
Putting the motor together was a little harder since you have more parts to
assemble then you do taking apart since some of the parts are froze together
on the old ones but all told not too hard. The gearing was a little tight
and I was worried it may strip the plastic drive gear but it didn't. I had
to re-aim the nozzle so to get higher on the window as well. Next oil change
I am putting the pa  ssat oil cooler in. larger so when I am towing it
should help with things better. I don't have an oil temp gauge and don't
know how I could get one to work well but I figure it can't hurt. That and
it will warm the oil up better as well. 

Also added a CAT fuel filter to the rabbit car. I figured best to have a
common filter and it filters better then OEM. The place that made the kit
stopped making the filter head which was the only one that took the thermo
T. Nicktane has a kit still that would work. I bought two used kits on
tdiclub. One was someones spare and another I bought a nicktane kit in
exchange. When I get the trucks injection pump sealed again (kind of getting
sick of that as it will be my 4th-both parts place ones went bad in under
40K miles). Thats all the updates on the VW's. 

Doing a lot of work on the JD 332 diesels this weekend as well.
Electrically. Which reminds me for a question: I would like to add a spare
alternator that I have for the rabbits that is in good shape on the 332
driven from the rear PTO. The tractor has a 20 amp OEM and it can't be
enlarged unless you remove the muffler and manifold so I am stuck there. I
was thinking for winter use when I get a cab and lights and possibly a cab
heater. The front PTO drives the blower and the rear pto could drive the
alternator. The pto clutches are electromagnetic so the light on the tractor
(3 fronts 2 rears), the PTO's and the charging would be as much as the
tractor alt could handle. So how would I hook the alt up. I don't want to
burn anything up. I know the VW alt requires 12 volts to excite it. So do I
hook the exciter wire to the battery (or even the PTO wire) and then the
power wires can they be hooked up straight to the lights? And does it just
ground through the tractor with both al  ternators and will they compete? Or
would I have to hook the alt up to the battery on the power cables and run
the lights from a switch through the battery power. I have seen one other
person run an alternator on the rear pto but I am just making sure I don't
fry something. No rush as I still need a cab and that won't happen for a
while. There-that question still involved a VW part on a diesel.
