Kevin Townsend Posted February 18, 2003 Share Posted February 18, 2003 Hi I have a '68 Series 2 and I'm trying to identify several of the major components. The car has the narrow wings of a SII and what looks like a reinforced Standard axle [as per Tony Weale's book] but is there a part number hidden somewhere that will confirm this along with the ratios fitted inside? Also the car currently has a Ford 1500 precrossflow engine but it's a 120E-6015 block rather than the 116E unit and may not be original ... I understand that the 120E was fitted with a high compression and a low compression head, does anyone know how to tell the difference? And finally the gearbox; the remote housing has the 118E 7K006 B designation cast on it, but does this necessarily identify the box itself? Is there another number hidden on the box that I can't see with the unit still in the car? Many thanks Kevin Link to comment Share on other sites More sharing options...
Nick Woods Posted February 19, 2003 Share Posted February 19, 2003 I cant help you directly, but have you tried getting in touch with the Lotus 7 Register Nick P8MRA - Red and Black 1.6K supersport, back on the road at last. See pictures of it being rebuilt here Link to comment Share on other sites More sharing options...
Old Septimus Posted February 19, 2003 Share Posted February 19, 2003 There would originally have been a metal tag under one of the bolts securing the gearbox top plate that could be interpreted by someone in the know to give the spec. If the box has been rebuilt this may have gone. I think you'll have to extract the diff and count the teeth to identify the axle ratio. Link to comment Share on other sites More sharing options...
Sheds Moderator Posted February 19, 2003 Share Posted February 19, 2003 If you want to get the FD ratio surely there is no need to extract the diff, just jack up a wheel and count the ratio of prop turns to wheel turns! Nice car though. It must be a handful on skinny tyres. Link to comment Share on other sites More sharing options...
Nigel Riches Posted February 20, 2003 Share Posted February 20, 2003 This may answer your engine block question http://freespace.virgin.net/tommy.sandham/databook.htm http://www.lotus-cortina.com/library/block/blocks.htm http://www.motorbase.com/engine/1/3/ click on "vehicles" And the axle ratios from the very old Pink Book are as follows, if it's a Standard Truimph the ratio would be either 4.55:1, or 4.11:1. Hope these are useful. Regards Nigel. 1982. 5 speed, clamshells. B.R.G / Ali. The True Colours. Link to comment Share on other sites More sharing options...
Old Septimus Posted February 20, 2003 Share Posted February 20, 2003 Battered is absolutely right - far more sensible way to check diff ratio. I suspect you'll be on intimate terms with the diff soon enough anyway! Link to comment Share on other sites More sharing options...
