-- Hints and Tips - New Shorty Covers Can Spell Transbrake Woes --
If you have a 'Shorty' Glide and decide to install one of the new shorty
covers that are available, you may be asking for trouble! TCI part #746401 (which
is the new cover with a needle bearing instead of a bushing) is slightly different
than the old unit. The output shaft hole in the cover is too large in diameter
and will not seal all of the cavities in the rear of the trans. If you are using
a "dual port" design transbrake, you will lose most of your pressure out of the
crescent shaped cavity close to the output shaft. The car will roll through the
lights, not want to back up, and eventually burn up the rear clutch pack.
This problem also occurs if your cover has been modified for use with a 4-link
car. Some transmission builders are machining the output shaft hole (on the transmission
side of the cover) to a slightly larger diameter for additional clearance for
the front yoke. This practice removes the sealing area necessary for the cover
gasket to seal the crescent-shaped cavity. Even if you do not have a "dual port"
valve body now, the case may have been modified to use one in the past. Look inside
the crescent shaped cavity. There is a passage leading to the valve body. This
is normal. However, if the case has been modified, you will find another passage
leading to the reverse piston.
There are a couple of cures. If you want
to keep the second port functional, the only cure is to make a plate to seal off
the back of the trans and then machine the back of the cover by the thickness
of the plate. Or, use an unmodified, older style cover. If you have a "dual port"
valve body, but the case has never been modified for it, then you only have to
plug the passage leading from the crescent shaped cavity to the valve body. Remove
the valve body and drill out the passage in the case to accept a 7/16" core hole
plug. The Peb Boys have one under Part # 362602. Coat the plug with JB Weld, Devcon,
or similar epoxy and drive into the port. On my transmission case, I then back
filled the entire passage with epoxy between the valve body and the newly installed
-- Hints and Tips - Simple Tire Gauge Modification for Shocks
If your car's shocks have air/nitrogen reservoirs, and you use a standard
gauge to check them, you won't ever get the pressure right. There is so little
volume inside the reservoir, that if any air escapes when using the gauge, the
pressure will change dramatically. From my old motorcycle days, I learned to use
a pencil type tire gauge. Install an additional O-ring of the correct diameter
in the port of the gauge. You will no longer lose any pressure. Now, before the
tip inside the gauge port can release the pin on the valve, you have to compress
the O-ring which seals off the valve stem perfectly. Result? No more loss in pressure
and accurate pressure settings.
-- New High Temp 'Gun-Style' Digital
Infrared Thermometer --
We now offer another Digital Infrared Thermometer
with Laser Sighting, Part # IRT4. The new Gun Style unit has a temperature range
of 0 to 788 degrees F, has a backlight, an 8:1 Optical Resolution, and an Auto-Off
feature. The introductory price is just $99.95! That is about what you would pay
for a unit WITHOUT laser sighting and with a lower temperature range. Comparable
prices for a unit with these specifications is about fifty or sixty dollars more.
-- FREE Software Download -- The DOS version of our DataMaster Analyzer
software, Version 2.0, is available to you as a FREE download on our web site.
(The Windows version is too big to download because of all the associated Windows
Dll's and other MicroSoft files that have to be installed.) You don't need a data
recorder to test the software and see exactly what a DataMaster Sportsman Computer
does better than any other data logger system in the world! Yes, better than the
most expensive data logger in the world. Only, ours is not expensive. If you have
any older version of this software, download this as a FREE update.
