hirondel Posted November 14, 2001 Share Posted November 14, 2001 Someone quite recently mentioned that Arch Motors 'stamped' the chassis with a/the number? If so, where? I ask because I've recently been over most of the chassis with hammerite and not come across it. Regard's... Link to comment Share on other sites More sharing options...
Big Brother Posted November 14, 2001 Share Posted November 14, 2001 IIRC...Passenger side roll bar mounting area, just behind the passengers left shoulder. Happy Hunting Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted November 14, 2001 Share Posted November 14, 2001 Mine's stamped under the pedal box lid, on the chassis part of the pedal box. Link to comment Share on other sites More sharing options...
Andrew Russell Posted November 14, 2001 Share Posted November 14, 2001 The full chassis number should be located where Alex says, under the pedal box cover. Arch also stamp the chassis with a seperate and different number around the offside rollbar mounting, showing I recall date of manufacture and another coded reference which means something to Caterham and Arch!

Philippe Giroulle Posted January 21, 2002 Share Posted January 21, 2002 Do I need to remove some parts (for instance the pedal box cover)to discover the chassis number as I'm not able to find it, neither around the pedal box, neither around the roll bar fixing area. The only place I can find it is on the pop-riveted ali plate near the engine. But, I believe there is certainly a place where it should be stamped in the chassis frame. Where?

Graham Perry Posted January 22, 2002 Share Posted January 22, 2002 You need to remove the pedalbox lid Link to comment Share on other sites More sharing options...
Chelspeed Posted January 22, 2002 Share Posted January 22, 2002 Someone once told me (forget who or when) that the number by your right shoulder (close to the roll bar mount) is something to do with type approval of the inertia reel seatbelt fittings. The seat belt mounts have to be tested by some authority or other, small volume type approval or whatever, the chassis then needs to be stamped to show the reference number of the test. Might be b*ll*cks of course. Link to comment Share on other sites More sharing options...
EFA Posted January 22, 2002 Share Posted January 22, 2002 The number under the pedal box is the Caterham Chassis number. On newer cars the pedal box cover is cut away so it can be read, on older cars the cover will need to be removed. The number on the top drivers inertia belt mount is the Arch record for the CBU number andf the year of manufacture. It uses the following format: Top line AM XX where XX are the least two signifcant digits of the year of manufacture. The bottom line is a 4 digit number, which is a chasis number which Arch use. Hence: AM 93 is a 1993 chassis, number 1234 1234 Fat Arn The NOW PROVEN R500 Eaterid=red> See the Lotus Seven Club 4 Counties Area Website hereid=green> Link to comment Share on other sites More sharing options...
Big Brother Posted January 22, 2002 Share Posted January 22, 2002 Older chassis had the number on the rollover bar mounting point. This was confirmed to me by Bruce at Arch Motors when I was tracing my cars history. The format is still the same though(eg AM81-1234) Steve www.Se7en-Up.co.uk id=limegreen> Link to comment Share on other sites More sharing options...
Chelspeed Posted January 23, 2002 Share Posted January 23, 2002 So the seatbelt test story was clearly bollocks then. Link to comment Share on other sites More sharing options...
EFA Posted January 23, 2002 Share Posted January 23, 2002 OOps, Steve - The rollbar mounting and the top seatbelt mounting are more or less the same place.....

elie boone Posted January 23, 2002 Share Posted January 23, 2002 In fact there are 3 chassis numders on a Caterham two exposed and one hidden. The one located at the rollbar is a frame nr.+ date Then there is the chassis nr. at the pedalbox And the hidden one ? surprice, surprice. It is on top of the wipermotor bracked, but you need a mirror to see it. Link to comment Share on other sites More sharing options...
