iana Posted May 15, 2019 Report Share Posted May 15, 2019 Just topping up the gearbox on the vitesse, Ive put about 1/2l of oil into the box, is this normal, I dont know when it was last topped up? It looks like theres a bit of a leak but only the odd drop that Ive noticed on the floor. Whilst the tunnel is out is there any other maintenace / lubrication tasks that are worth doing before I put the tunnel back? I’ve just checked the gear lever and I think a new bush kit is required.

Pete Lewis Posted May 15, 2019 Report Share Posted May 15, 2019 the combined capacity of GB + OD is 2.4 pints so it needed a top up whilst the tunnel is off you could check the throw of the OD solenoid and clean the OD filter Gauze and the ring magnets add an extention pipe to the clutch slave so you can bleed it from the engine bay make sure there is a 7/16" washer fitted between the speedo pinion hsg and the angle drive , these must not have any pre load or the drive will fail quickly. its any washer used as a spacer. Oh and cut a tunnel hole to access the GB filler plug for next time pete Link to comment Share on other sites More sharing options...
iana Posted May 15, 2019 Author Report Share Posted May 15, 2019 Pete, thanks, the plan for next year is a fibre glass tunnel - is it still worth doing an access on the old fibre one? I think there is a small leak from the top of the gearbox, Ive cleaned the gearbox so I will be able to tell properly next time, unless its an easy fix / check? Having looked at it again the leak looks like it could be the switch on the top. Not sure I understand the 7/16" washer comment - really silly question now - is that a washer that fits inside the knurled nut of the angle drive - also should the nut be tight as mine moves if you move the cable - seems wrong to me. .

Pete Lewis Posted May 15, 2019 Report Share Posted May 15, 2019 Yes just slips inside , stops the drive bottoming out , the knurled nut is like that to be finger tight dont wraunch it up There is a oil seal on the pinion but depending on evolution can be hard to change as some shafts are held in with a ' sod to remove 'pin So a bit of movement/rotation is not overly concerning and it should not leak as there not supposed to be oil in there. Well maybe a mist, Make the hole its good practice and you can make the new one a mk2 Pete Link to comment Share on other sites More sharing options...
iana Posted May 15, 2019 Author Report Share Posted May 15, 2019 Well I think the leak is in this area, but feeling is the fibre washer - is this an easy fix? Guess so as I’ll be rebushing the lever as the plastic bit has disintegrated. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 15, 2019 Report Share Posted May 15, 2019 the switch has a thin fibre washer a smear of sealer will suffice, the switch only needs a good nip , any gorilla tightening will wreck it you can get a leak if the 0 ring in the tower has worn, ( where the remote shaft exits the top hsg.) but they are hopeless to replace, they do come in the remote bush kit, you have to strip out the fwd section the 0 ring sits in a groove the shaft passes through them , but most chop the new 0 rings when inserting the shaft and the job is now worse than before ....leave them alone !! yours has the double cam in front of the remote one for OD one for reverse , ...old design but cant leak !!!

GT6M Posted May 17, 2019 Report Share Posted May 17, 2019 on top oft selector bit under the remote, there a wee wol that lets it breath oil mist does come out of there,after a while,it looks like a leak esp if yer actually using yer car alot, as oil gets hotter moer vapours come of = moer oil mist = moer oil on side oft box so no a leak as such !! Me self, I bung a rag in there to catch the oil mist and if yer gonna fill GB / diff noo an then, get yan of thee,s https://www.ebay.co.uk/sch/i.html?_from=R40&_nkw=oil+filling+gun&_sacat=0&_sop=15 1 Link to comment Share on other sites More sharing options...

68vitesse Posted May 18, 2019 Report Share Posted May 18, 2019 As most overdrive problems are electrical give a good check of the wiring and connectors, heat, vibration and oil can do nasty things to them. Regards Paul Link to comment Share on other sites More sharing options...
johny Posted May 18, 2019 Report Share Posted May 18, 2019 I'd also add checking the tightness of all the gearbox bolts as mine always seem to be loose. I should probably replace all the spring washers to stop this happening.... Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 18, 2019 Report Share Posted May 18, 2019 the only loose ones ive encountered were on Gullys, box rebuilt near corby. pete 1 Link to comment Share on other sites More sharing options...
johny Posted May 18, 2019 Report Share Posted May 18, 2019 Still worth checking them isn't it? If they do loosen off it doesn't help keep these boxes dry..... Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 18, 2019 Report Share Posted May 18, 2019 theres a lot of nuts need.......... checking Ha !! Pete Link to comment Share on other sites More sharing options...
dave.vitesse Posted May 18, 2019 Report Share Posted May 18, 2019 Maybe something for the future. You can cut a hole in the gearbox cover to get at the oil filler plug. The piece that come out of the cover can then be used to make a cover for the hole. I use bit and pieces from my socket set to remove and do up the plug. Just an idea.

Bfg Posted May 19, 2019 Report Share Posted May 19, 2019 Wow.. there's a great deal of good advice going on here.. Thanks guys Link to comment Share on other sites More sharing options...
iana Posted July 29, 2019 Author Report Share Posted July 29, 2019 Last time I topped the gearbox up I had intended to replace the tunnel with a modern grp one but couldnt get one in time, I am now getting the seats repaired so decided to replace the tunnel why the car has less in it - Im fitting a grp with a side access panel so filling / checking will be more straight forward from now on. I removed the tunnel today and it appears theres still an oil leak, I think its either the top gasket or where the gear change comes out of the box. I was also checking for breather vents - where are they located. Is there a guide to fitting the rebush kit or is it fairly obvious once you start? Is this the breather?

johny Posted July 29, 2019 Report Share Posted July 29, 2019 First I would check that the bolts are all tightened correctly - mine just seem to undo themselves and joints start to weep☹️ Link to comment Share on other sites More sharing options...
iana Posted July 29, 2019 Author Report Share Posted July 29, 2019 Johny I checked that earlier and they're all tight (may not be torqued to correct setting) but were tight - the front 2 nuts and threaded stud were coated in oil so I'd hoped thats was all that was wrong - would a drop of thread lock stop them coming loose?

johny Posted July 29, 2019 Report Share Posted July 29, 2019 If I was rebuilding and had everything clean I would threadlock them but with it in situ and oily I dont think itll achieve much. I see that GT6M described where the breather hole was in a previous post and I must admit Ive never checked mine.... Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 29, 2019 Report Share Posted July 29, 2019 some below the oil line have a copper washer on .... or should have slacken / remove nuts add sealer re tighten hand tight . its ally no gorilla required Pete OD is an open simple roundish breather on top of the OD unit under the remote hsg. it can leak due to splash . its not very clever i added a tube on mine to dissipate any leakage there are other holes in the gearbox top cover but the OD one is much bigger and its all in a common space pete Link to comment Share on other sites More sharing options...
johny Posted July 29, 2019 Report Share Posted July 29, 2019 Pete where is it on non OD or is it just those holes in the top cover? Link to comment Share on other sites More sharing options...

Pete Lewis Posted July 30, 2019 Report Share Posted July 30, 2019 on early 1600 3 sync OD its not listed at all seems to be introduced only on the 2 ltr supplement why on earth would you want to plug it , with an OD its a common case one breather or two, so what the OD ones can spill anyway , they are not baffled from splash Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted July 30, 2019 Report Share Posted July 30, 2019 I don't think it's a plug, just a loose-fitting bung, same as the circlip in the diff. Rivetted but not tight so as to move about, let pressure out and keep the hole clear as it moves. Link to comment Share on other sites More sharing options...
