I got to looking at my Amphi's steering system and guess what I found? Toe-in
was a whopping 0.85 inches! It's no wonder the car
wandered around a bit, seemingly always searching for a puddle as Amphicars are
sometimes known to do. Not only that, someone had
previously installed some after market steering dampener on the long tie rod.
Problem with that (besides being completely
unnecessary) was the first time the car hit a big dip, it bent the tie rod about
1.5 inches. After throwing out that jury rigged
system and straightening the tie rod, I started adjusting the toe-in. (Be
prepared for rusty threads. Helps a lot to have
14mm-1.5 left and right hand taps and dies to clean up the threads).
My technique was this: I used a 1/4 inch dowel rod inside a piece of small
diameter rigid plastic pipe. Telescope the assembly to
take measurements as close as possible to the front and rear OD of the wheel
rims. (Car on the ground, wheels straight ahead).
The front measurement should be 1/32 to 1/8 inch less than the rear measurement
according to the Amphicar maintenance manual. (10
to 30 minutes for those using a real toe-in adjusting system.)
Wow, what a difference proper toe-in makes. The Amphicar handles like a dream
now - at least on the road.
Here's a visual test you can do to see if your Amphi toe-in is in the ballpark.
(BTW, the specs for the Amphicar are 47.31" front
track and 49.20" rear track.) With the car on the ground, turn the steering
wheel so you can sight along the left front tire to
about one half inch in on the rear tire. Now, without touching anything, take a
look at how the right front tire sights to its
rear tire. It should also appear about the same distance - about a half inch
in. Mine previously appeared to be about 6 inches
out front the back tire with that .85 inch toe-in. With toe-in properly
adjusted, both front tires should sight about a half inch
in on both back tires. Hope this helps.
