Guest Posted February 11, 2014 Share Posted February 11, 2014 Anyone got any pics of how it is installed / riveted..? Really need to visualise what I need to do... http://caterhamparts.co.uk/product.php?id_product=4434 Edited by - Roadracer1977 on 11 Feb 2014 15:44:00 Link to comment Share on other sites More sharing options...
Mark w Posted February 11, 2014 Share Posted February 11, 2014 Daniel I haven't got one of these on mine but would suggest that you don't want to actually fix this to the chassis permanently until you have all the drive train ( gearbox diff and engine ) fitted , centralised in the chassis and set at the correct height . I would slide it on the prop shaft ( the way round that you can access the holes to rivet ) and leave the fixing until later .

Not sure if I'm trying to fit it properly, but it just will not go in whatever way I try... It'd be great to see an 'installed' picture if anyone would be so good?

Guest Posted February 14, 2014 Share Posted February 14, 2014 I have fitted this now. Used a Dremel 575 to get into the tunnel with the Dremel chuck attachment. Then drilled from the tunnel through to the passenger and driver compartments using a 4mm metal drill bit and riveted into the tunnel. Quite fiddly and very time consuming to fit.

Nigel Riches Posted February 15, 2014 Share Posted February 15, 2014 If you have rivetted this to the aluminium tunnel you've just added some ballast. Got to be soundly attached to something of more substance than the tunnel skin. Link to comment Share on other sites More sharing options...
Martin J Posted February 15, 2014 Share Posted February 15, 2014 I am just wondering what this guard is for? Is it stop the prop shaft tearing it's way through the car if a UJ should fail? I assume only needed on the high powered models. Link to comment Share on other sites More sharing options...
mic Posted February 15, 2014 Share Posted February 15, 2014 Yes Martin, its a close fit round the prop to restrict the thrashing around if the U/J fails. It should be attached to the top and bottom tunnel tubes as well as the ally panels. Link to comment Share on other sites More sharing options...
Mark w Posted February 15, 2014 Share Posted February 15, 2014 I cannot think why this wouldn't be fitted as part of the chassis build by Caterham unless the clearance needs to be adjusted when the drivetrain is fully installed . I hope I am wrong for Daniels sake . How much larger is the hole than the O/D of the props shaft ? Link to comment Share on other sites More sharing options...
mic Posted February 15, 2014 Share Posted February 15, 2014 They are only fitted to R500/620. The hole is just large enough to get the prop through. Link to comment Share on other sites More sharing options...

I wonder if he should have left attaching it until after the prop shaft was attached to the gearbox for perfect alignment? Hope it works out OK. Difficult with minimal instructions.

Guest Posted February 15, 2014 Share Posted February 15, 2014 Guys... All checked in with Derek at CC... I'm doing everything as per his instructions. Riveted to top and bottom chassis rails and tunnel skin. There's decent clearance for the guard and is ok to install at this stage... Check out my blog for pics etc. Cheers Link to comment Share on other sites More sharing options...

SLR69 Posted February 15, 2014 Share Posted February 15, 2014 I would suggest everyone fits one having seen what happens when a U/J fails at speed and the prop shaft lets go. Saw a Caterham last year where this happened which destroyed the passenger side transmission tunnel and much of the passenger seat. If there had been a passenger in the car at the time the injuries would have been horrendous ! Link to comment Share on other sites More sharing options...
Martin J Posted February 15, 2014 Share Posted February 15, 2014 Why do the UJ's fail? It's not something you hear about failing on "ordinary" rear drive cars. Or is it that caterham have used a particular joint that isn't designed to cope with the loads or high rpm from higher powered or racing sevens.

Martin J Posted February 15, 2014 Share Posted February 15, 2014 Scary stuff I hope the driver wasn't badly hurt. Is a sequential box more brutal to the drive train? Link to comment Share on other sites More sharing options...
BBL Posted February 15, 2014 Share Posted February 15, 2014 Quoting Martin Jeffrey: Scary stuff I hope the driver wasn't badly hurt. Driver was unharmed, as this is a LHD car. But a great photo to show the potential for damage. Link to comment Share on other sites More sharing options...
nickh7 Posted February 16, 2014 Share Posted February 16, 2014 Came across a Robin Hood in a ditch where a uj had let go he was very luck . Had to say he had bodged a prop shaft and got what he deserved Link to comment Share on other sites More sharing options...
Alaskossie Posted February 20, 2014 Share Posted February 20, 2014 Has anyone adapted and fitted one of these to a Series 3 Arch chassis? Also, as an after-assembly item, is there any reason why it could not be divided vertically down the middle, placed in two pieces into the tunnel, riveted in place around the propshaft, and joined top and bottom with pre-made join pieces with bolts and lock-nuts? Slightly heavier, perhaps, but it would obviate the need to disconnect the drivetrain to install. Link to comment Share on other sites More sharing options...
catastrada Posted February 20, 2014 Share Posted February 20, 2014 My new Sadev seq. Gearbox should be delivered next week and I will fit it the week after. As a result I will replace my standard propshaft with the R500 with seq. propshaft type. FYI, although it does not appear on their website yet, Caterham does sell another type of proshaft that was deisgned for the R600/R620. My car is an S3 with Arch chassis. I ordered the prop guard as well. I will let you know how it goes. Edited by - Catastrada on 20 Feb 2014 07:39:17 Link to comment Share on other sites More sharing options...
Damdy-Cash Posted February 20, 2014 Share Posted February 20, 2014 as this is anyway not the most complicated design it would be possible to get it made to fit. What thickness of material is the original part? Cheers Volker Link to comment Share on other sites More sharing options...
David Mirylees Posted February 20, 2014 Share Posted February 20, 2014 This is what happens to a Lotus series 4 7 when the front UJ lets go S4 7 UJ Failure Luckily happened at around 90mph so the propshaft shattered rather than pole vaulting the car. The fire was caused by the flailing prop severing the main fuel line. Driver and passenger OK. All Caterham's should be fitted at birth with protection in the front UJ area!!

catastrada Posted March 5, 2014 Share Posted March 5, 2014 As planed I'm in the process of fitting my Sadev seq. Gearbox. Currently we are stuck as yesterday evening we discovered that the new uprated proshaft sent by Caterham has 2 impacts on the side that goes into the gearbox, exactly where the gearbox seal sits. It means that the seal will be damaged pretty soon if we fit it. We need to wait for a replacement... Picture of 1 impact The second impact is 180°opposite... But we fitted the propshaft guard in my tunnel (S3 imperial) : picture As we have a R500D in the garage, we were able to take measurements. The fitting is not plug and play. But when we look how CC fitted it to the R500D, it seems that it wasn't either. Link to comment Share on other sites More sharing options...
Martin J Posted March 5, 2014 Share Posted March 5, 2014 All Caterham's should be fitted at birth with protection in the front UJ area!! eek smiley but why do the UJ's fail? Is it because a standard joint has been used & it's being pushed beyond it's design limits? If so caterham should specify a stronger joint.
