jingars Posted August 23, 2013 Share Posted August 23, 2013 Please assist a numpty.... Yesterday I attended Road & Race Transmissions and Phil kindly swapped by debit card PIN for a shiny new Titan LSD 😬  Checking what I think is the last build manual I downloaded (I cannot find a build manual download on the revamped website), it has a torque value of 47 Nm for the bolts. Will buy new bolts, as is recommended in searches of previous tech talk threads on here. Build manual recommends either Loctite Threadlock 242 or 243. 242 has a breakaway torque of 11.5Nm and 243 a breakaway torque 26Nm. As 26 is quite a way from 47, can someone explain in small words what I should be seeking to achieve with the thread locker. I am sure that after all this time Caterham have it right, but I would like a bit of understanding and reassurance. The underside of my car is an oily and alien world to me; this should be fun! TIA.

Member Jonathan Kay Posted August 23, 2013 Member Share Posted August 23, 2013 What size are the bolts? Jonathan Link to comment Share on other sites More sharing options...

Paul McKenzie Posted August 23, 2013 Share Posted August 23, 2013 You're simply threadlocking the bolts to stop them vibrating loose, so either will do....unless of course you're planning on not using the bolts and threadlocking the diff and propshaft flanges together...in which case you'll need better glue Link to comment Share on other sites More sharing options...

Mavic82 Posted August 23, 2013 Share Posted August 23, 2013 If I recall don't the genuine ford parts already have a thread lock coating when you buy them? Enjoy the LSD  Guy Link to comment Share on other sites More sharing options...
rgrigsby Posted August 23, 2013 Share Posted August 23, 2013 The last ones I bought had a blue coating which I think was some kind of threadlock. Link to comment Share on other sites More sharing options...
jingars Posted August 23, 2013 Author Share Posted August 23, 2013 The genuine Frod ones may well have threadlock already applied, but Caterham currently supply "clean" caphead bolts. Would prefer standard bolts if possible, so will seek to source some. Hello to "Grizzly" Foulger Link to comment Share on other sites More sharing options...
Mankee Posted August 23, 2013 Share Posted August 23, 2013 There's a few sets of genuine Ford OEM "blue" propshaft bolts on eBay. £15 a set though! Alternatives are available if you bash in something like "sierra propshaft bolts". Link to comment Share on other sites More sharing options...
jingars Posted August 23, 2013 Author Share Posted August 23, 2013 Thanks, Mankee. As Caterham have moved to 12.9 I would like to source 12.9 bolts. Burton have these bolts under the same part number as Caterham use for their cap heads, but they are 10.9.

Grubbster Posted August 23, 2013 Share Posted August 23, 2013 Be careful the CC supplied ones aren't made of cheese  Donut machine in the making then Jingars! Nice plan Link to comment Share on other sites More sharing options...
DJ. Posted August 23, 2013 Share Posted August 23, 2013 I had a Titan off Phil as well, and ordered new bolts from Caterham which arrived without the blue thread lock. I just used the loctite 243 and torqued them up, they're still tight after 8000 miles  Duncan Link to comment Share on other sites More sharing options...
jingars Posted August 23, 2013 Author Share Posted August 23, 2013 Thanks  Having had a nose around, it would seem as though I am going to struggle to get any hex head bolts in 12.9 - which is probably why Caterham changed to providing cap heads.
