I have SR3XX. When yall service the axles, do you replace the clamps each and every time? Where can I get spare clamps? Are they all the same size? What is the appropriate tool for tightening?
I don't know if the current clamps are the same as mine, but I'll bet they are. I found some and bought 50 clamps a couple of years ago, and I'm steadily depleting my stash. I posted here about that source... let me see if I can find it.
As far as tools go, you'll need a special tool. Here's a link to the tool I use at Summit Racing.
Let's see if this link works:
Are these clamps supposed to be Oetiker 167 series? I just removed my clamps, all it shows is Oetiker 89. It measures 7mm wide. Just trying to find actual part number for reference and purchase.
That is exactly what local race shop uses, worm gear clamps.
However, I am sure hopeful that someone that understands Oetiker part numbers will chime in as I would like to use them instead if I can identify the correct part number. Unfortunately, the only marking on these clamps is Oetiker 89, which if this is really 16700089, then it seems too large - thus does not make sense.
I'll have a look at my stock of Oetiker clamps. I have 3 sizes to fit the two different SR8 gearboxes (Quaife and Hewland). The big worm gear clamps work fine, but they can be over-tightened, leading to the boot squirming and wearing out. Plus they are heavier, leading to catastrophic loss in lap times. 🙂
The last set of clamps I bought the invoice said they were 88MM.
It seems crazy to me that their part numbers are not stamped on actual clamps. From their catalog:
So, since my clamps are stamped 89 Oetiker, wonder which one it is for SR3?
Ok, I talked to a guy at Oetiker, he confirmed this is 16700085 part number.
Do you guys have a link to purchase these? I assume the tool is pretty self explanatory.
Belmetric did not carry the correct size, so I talked to them and they added them, stock is due in today.
I thought I was being clever when I ordered some "universal" cv boot clamps from Amazon. A clamp is a clamp, right? The problem with these is that they are too wide (9mm) to lock the boot into the groove of the housing. I just ordered some of the Oetiker clamps per above. Thanks for doing the research on these.
