Greetings… Not sure if the finish is correct but this kit has both 5 mm and 9 mm bands and clamps. http://www.authenticclassics.com/Cotter ... 003406.htm

Re: Cheney Clamps
Tim, thanks a MILLION. That is exactly what I was looking for, the right stuff for a decent price. They carry both the 5mm type for the cylinder heads and the 9mm for the heater hoses. Perfect, thank you again.

Re: Cheney Clamps
I got some Cheney clamps from XK's Unlimited and they leak. What causes them leak and what is the fix? It feels like they are tight enough. Thanks.

Re: Cheney Clamps
john,
all the repro cheneys leak. only solution is to buy originals. also, the repro ones dont have all the proper numbers on the band which identifies the size per the parts manuals.

Re: Cheney Clamps
Even the originals don't clamp as well as a stainless steel clamp where one can use a hex wrench or socket to tighten it. My solution is to slide the Cheney clamp on the hose and loosely tighten it a couple of inches out of the way. Then use a regular clamp to tighten the hose down as normal. After a couple of months, when the hose is bonded to the nipple, remove the regular clamp, slide the Cheney one in position and tighten it.Edward 96GTS wrote:john,

Re: Cheney Clamps
I wanted to make a post and close the loop on this issue of repro clamps and their leaking. After months of tightening and re-tightening and stripping a few. I removed the hoses, cleaned the surfaces and applied RTV, that did it, leaks finally stopped. So, the moral of the story is apply some sealant from the get-go and the repo clamps will serve you well enough. Thanks.

Re: Cheney Clamps
seems like using the repro clamps is risky. a lot of work to make a bad product work.
original clamps are readily available and infinitely more reliable.

Re: Cheney Clamps
On the later run of the 250 cars 1962-63, I remember seeing the wrapping band type clamps (Copiglia??) for the heater hoses and Cheney for the rest. Is this the case or were they all Cheney by that time? Thanks in advance.

You are correct John. Copiglia for heater and Cheney for others.Page 46 -owners manual . This also shows the orientation of the cheney clamps.

Re: Cheney Clamps
Cheney also for the vacuum hoses and road draft tubes. The band type clamps also for the large fresh air hoses.

Re: Cheney Clamps
In researching Cheney clamps I found that there are three different designs of these clamps used in the 50's & 60's. My information comes from what is posted on the internet on the Jaguar forums. The first design was used in the 1950's. The features of this design are; 1) The CHENEY name on the drive screw cover is is curved and stamped above the size number. 2) The size number is centered on the the axis of the drive screw. 3) Across the drive cover is stamped "AGS 605". 4) The band under the drive has a raised arrow impression. 5) The end of the tail of the band has a semi-circular notch. The second design appeared in the early 60's and the features are; 1) The CHENEY name is stamped in a straight line along the axis of the drive. 2) The is stamped below the name and denoted "No _". 3) The cover is stamped "AGS 605" like the first design. 4) The raised impression under the band is now curved. 5) the end of the band now has a "V" notch. The third design was a result of the UK adopting a new standard for clamps in Mat of 1963, "BS3628". Features of this design are; 1) The drive cover is marked with CHENEY and BS3628 along the axis of the drive screw. 2) the band has the raised impression and notch in the end the same as the second design. 3) The size is now stamped in the band below the drive, eg. 212S. I realize that this may be a bit of minutia in regard to these clamps but this is the level of detail that Jaguar people are facing for car shows. Attached are photos of the three types side by side for comparison.
