Qu1ckn1ck Posted March 15, 2017 Report Share Posted March 15, 2017 I currently have severe oil leaks from the gearbox (speedo cable entry) and differential (near side drive shaft seal) plus the added irritation of a sticking clutch. Apart from the leaks, the gearbox, overdrive and differential are quiet and appear to be in good mechanical order. I also need to lower the rear as I am told the car has been incorrectly fitted with a Vitesse rear spring. I am looking for recommendations as to who could carry out this work quickly and effectively in the vicinity of North Herts. Has anyone had any experience of Robsport International at Shepreth/Melbourn ? Link to comment Share on other sites More sharing options...
Gully Posted March 15, 2017 Report Share Posted March 15, 2017 Robsport rebuilt my diff and replaced the clutch on my GT6 last year - all good. They fitted a reconditioned gearbox too (which I supplied) - no problem with the fitting, but the 'box itself caused some problems completely unconnected with Robsport's work. They are not the cheapest and will probably send all your components away for overhaul, but can't fault their work. They also fitted the CV conversion to my car when the rubber doughnuts deteriorated and fitted a new rear spring to overcome the 40 year sag! Worth giving Simon a call - they usually have a waiting list of a few weeks. Gully 1 Link to comment Share on other sites More sharing options...

Clive Posted March 16, 2017 Report Share Posted March 16, 2017 Mordale motors in Norf London may be able to help. Again an enviable reputation. I know they can reseal gearboxes on site, a friend had one on his Sprint sorted bu them. 1 Link to comment Share on other sites More sharing options...
JohnD Posted March 16, 2017 Report Share Posted March 16, 2017 This shows you the differences between various rear springs. I'd suggest that the stiffer Vitesse spring is better for performance, as it will limit suspension travel, avoiding extremes of camber change, and that lowering the car by a spacer between the spring and the diff will be more effective than seeking a new spring.

Pete Lewis Posted March 17, 2017 Report Share Posted March 17, 2017 Nick, so we know, can you count the no. of leaves on yours ??? Pete Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted March 17, 2017 Author Report Share Posted March 17, 2017 Pete, I will roll the GT6 out from the back of the garage this weekend, count the leaves and try and free the clutch. I will let you know the results. Nick Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 18, 2017 Report Share Posted March 18, 2017 then maybe we can pull a economical plan together Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted March 19, 2017 Author Report Share Posted March 19, 2017 Nick, so we know, can you count the no. of leaves on yours ??? Pete It is a brand new spring and I have counted six leaves. A partial reading of the Canley label on the spring reads "... WOR020623...". Six leaves appears correct for a GT6 Mk3 so it looks like I may have been fed "fake news" when informed it had the wrong spring fitted. Link to comment Share on other sites More sharing options...

Pete Lewis Posted March 19, 2017 Report Share Posted March 19, 2017 Owens top spring supplier I Cant trace that part number pete Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted March 20, 2017 Author Report Share Posted March 20, 2017 Finally freed the clutch today and got the GT6 round to Tony Solich who will now tackle the transmission faults from the leaking diff and gearbox to the sticking clutch. Despite finding that the NEW rear spring fitted is the six blade GT6 version, the car stands high at the rear and has minimal rear negative camber so I am taking JohnD and Pete's advice and fitting a 3/4" spacer and new studs between diff and spring. Target is to get the GT6 back on the road within two weeks with it's incontinence problems resolved. Link to comment Share on other sites More sharing options...

JohnD Posted April 3, 2017 Report Share Posted April 3, 2017 Wow! Your own two-post? Green with envy! If you're lowering it, I'd turn that pipe clamp on the exhaust around - nuts on top. It's unlikely to ground, but you don't want it torn off. Nice car! John Link to comment Share on other sites More sharing options...

John Thanks John, not exactly my two-post but my cars have spent a large amount of time on there so I can probably claim squatters rights.
