GPBox Posted March 3, 2018 Share Posted March 3, 2018 it was all going so well...just installing a l/w flywheel in my 1.6 K. ..all looking good until I tried to install pressure plate...my old bolts are a smaller size than the new l/w flywheel...any ideas as to the size required for the l/w f/w ?...I bought it ages ago on BC...don't know what it was originally intended for...checked the size/trigger pattern etc...all that looks good.thanks Graham Link to comment Share on other sites More sharing options...
revilla Posted March 3, 2018 Share Posted March 3, 2018 Standard bolts often M7. Lightweight flywheel usually M8. Pressure plate holes usually accommodate M8s. Link to comment Share on other sites More sharing options...
revilla Posted March 3, 2018 Share Posted March 3, 2018 Just measured one of the M7s that Caterham now supply in place of the original Rover DAM8124. 15mm long and 8.8 grade high tensile. So you will probably want M8 x 15mm flange bolts in 8.8 or above. Link to comment Share on other sites More sharing options...
GPBox Posted March 3, 2018 Author Share Posted March 3, 2018 Great thanks guys....Caterham have an odd description here: https://caterhamparts.co.uk/bolts/4192-fixing-bolt-strut-top-k-clutch-to-lightweight-flywheel.html?search_query=clutch+bolts&results=237, and QED sounds a bit more specific here: https://qedmotorsport.co.uk/qed-shop/rover-k-series/flywheels/clutch-to-flywheel-bolt-standard/early/1-8 think the QED spec looks right.

revilla Posted March 3, 2018 Share Posted March 3, 2018 Yes the QED M8 ones look like they should be right. QED are about five minutes from my house. I'm sure their postage will be reasonable but if there are any problems or you want me to check anything out let me know. Link to comment Share on other sites More sharing options...

oilyhands Posted March 3, 2018 Share Posted March 3, 2018 M8 x 12mm are the right size, not all flywheels will accommodate M8 x 15. In case of difficulty I usually keep them in stock.Oily Link to comment Share on other sites More sharing options...
