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.
I replaced mine with a heavy duty worm gear hose clamp. Has worked great.
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.
Nice work Dan! I'm still digging around looking for my stack. It's here somewhere...
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.
