Tony Jones Posted March 14, 2009 Share Posted March 14, 2009 I have seen lots of R380 boxes for sale from tdi's, Td5's and v8's but what sort of torque can they take and is there any particular suffix of box that has the closest ratio's to look out for?

western Posted March 14, 2009 Share Posted March 14, 2009 380Nm of torque cos that's how the designation came about R = Rover 380 = 380 Newton Metres of torque [capacity] Quote Link to comment Share on other sites More sharing options...

You learn something new every day, will have to convert that to non euro lb/ft. Thanks for letting me know. It makes sense. I suppose the LT77 was named the same way light truck and 77lb/ft torgue!! Cheers for the info. Anyone any idea on the ratio's? Quote Link to comment Share on other sites More sharing options...
nakatanenga Posted March 14, 2009 Share Posted March 14, 2009 late suffixes of the R380 (MY05 on) were uprated for 420Nm! Quote Link to comment Share on other sites More sharing options...

LT77 = LT = Leyland Transmissions 77 = 77mm between the main & layshaft centrelines. Quote Link to comment Share on other sites More sharing options...

western Posted March 14, 2009 Share Posted March 14, 2009 have a read/chat to Ashcroft Transmisiions R380 info Quote Link to comment Share on other sites More sharing options...
rick Posted March 17, 2009 Share Posted March 17, 2009 late suffixes of the R380 (MY05 on) were uprated for 420Nm! Actually I think you'll find that occurred in late '98 with the suffix 'K' box. I asked Dave Ashcroft about this on another board once and he said they treated the 'K' (late '98, early '99) and 'L' boxes as dimensionally identical and used the same parts in a rebuild, although there are a couple of small differences in a few areas and it didn't alter the strength of the box. These later suffix boxes are quite a bit different and therefore quite a bit stronger than the earlier 'J' boxes. Quote Link to comment Share on other sites More sharing options...
