[Tigers] Embarrassed and Happy also...

[Larry Mayfield]

Lemme deal with the embarrassed part first, lol. Long ago I had purchased 2
posi units. One I ran in the Tiger in the late 60’s for chuckles with a 4.55
gear set. Learned a lot, I did. That your daily driver is not a race car,
nor is your race car a daily driver, especially if its 25 miles or more to
and fro.  So I grabbed a posi that fit lower ring and pinion sets. I knew
that there were difference way back then but the passage of time dims all
thigs, lol.  First, the posi that fits R&P units above I think it is, 3.73
ratios has a different location for the ring gear. For instance the flange
where the ring gear is installed is roughly ½ inch closer to the ;inion
centerline. That is because as gear ratios get lower (higher numerically)
the pinion gears get smaller and the ring gear has to move towards the
pinion to mate.  A 2.88 R&P has a large diameter pinion gear set so the
outward displacement of the flange was needed to assure mating with the
pinion. And then there is the difference in fasteners. The 2.88 ring gear is
held on with large bolts, the head uses a ¾ inch socket to remove them. Then
the 4.55 ring gear posi has smaller fasteners. Simple check of trying to put
a 2.88 bolt into the flange on the 4.55 posi showed that .  By this time I
had remembered all this stuff that I had forgotten at least 50 years ago.
Red faced
. So along witht eh 4.5 R&P I have for sale (already spoken for as
soon as I decide what to ask for it) I need to sell or swap my low gear
ratio posi for a high gear one. Or at best swap the POSI and R&P for a high
gear ratio (2.88 compatible) posi. 

 

Next the happiness
 I finished the drive shaft u-joint install yesterday.
While there is simplicity in putting all these things together, they can be
full on boogers when they want to be. Mine was like that.  I did persevere,
however, with Rick McLeod at SS and the job is now done.  So I fired up the
car, and after making sure that lug nuts were torqued to around 50 ft-lbs
(not pound feet) and that I had air in the tire, and fuel in the tank, we
drive it around the block, about  ¼ mile!  The left front brake was grabby
and pulling to the left so I probably need to bleed then things. Dot 3,
right? And even after replacing the fuel vent line and filler neck hose, and
fixing a gas leak at the pump area, I STILL have the damned leaky gas smell.
But the car ran and did fine after nearly 10 years of sitting patiently.
So, need to bleed the brakes, and move the steering wheel around a bit to
more horizontal location and then drive it some more.  Had a bit of oil on
the drive way but I suspect that was from rear main not being warmed up and
from sitting forever.   Will see how that goes today. 

 

Like to hear from someone or anyone who would like to swap posi with me, or
maybe has one to sell that is of the correct configuration (axle spline
count, and ring gear compatibility). As long as it is not the same category
as the nation debt ceiling


 

Thank all ya’ll for help in the past. Us older folk need the assistance; we
are thankful for it!
