Spinner Safety Wiring - Straight In

[Larry N Johnson]

Hal Copple, thanks for posting. No safety wire on spinners? Well, well, well... Surprize!

A few years ago I witnessed a Jim Click Racing vintage Cobra in a race in Portland OR. Here is the car vintage racing at Pacific Raceway:



During a tire change in the middle of the race, guess what? No safety wire!

This summer, we enjoyed the 3-day BACC "Cobras to the Coast" run. An original 427 Cobra was on the trip. Guess what? No safey wire!

Anyway, I spoke in detail to Lynn Park 5 years ago on safety wiring Trigos. He said the steps are as follows:

1. Tighten the spinners w a lead hammer, good and tight. Mkae sure the rim is flat against the face of the rotor (or drum).

2. The safety wire is an indicator, so wire it perpendicular to the spoke, not angled.

3. Drill 2 small holes in the spinner and one in the spoke.

4. Take a loop of wire around 12-18" long, fold in half.

5. Thread the wire through both holes in the spinner, loop showing.

6. Use the special tool to twist the wire with length enough to reach the spoke.

7. Thread one wire thru the spoke hole. Loop it back around to join the other wire.

8. Now twist the pair or wires an inch or more.

9. Cut off excess and fold twisted wire behind spoke.

Here is the finished product:


The perpendicular wire is an indicator telling if the spinner has moved from accelleration or braking (hense straight in, not angled). Check the indicators from time to time. Carry the lead hammer with you at all times.

The reality is that tightening w the hammer is the key to safety, not the "safety" wire method one way or another. So they are all "good"; no "right" or "wrong" way to do it. (IMHO)

"Keep your spinners tight."

Just want to comment on this (as I was going through this post looking for the lead hammer reform tool).

The above statement is impossible. The wheel cannot make the spinner move in any direction from accelleration or braking. The wheel is held in place by the hub pins, so the wheel cannot "spin" in relation to the knock off. A knock off can ONLY come loose from vibration, and usually if the wheel is not fully seated to the hub. This would allow "rocking" of the rim on the hub which in conjunction with vibration would cause the spinner to loosen.
