Davidw Posted October 13, 2013 Report Share Posted October 13, 2013 The clutch saga continues. The box is now out and there seems to be reasonable amount of oil on it. Some of this is engine oil which I suspect has climbed out of the dipstick on the ignition side of the engine due to the inadequate closed circuit breathing system. But there is definitely some EP90 too. Not much but some. I will obviously check the breather hole, but is it worth going round and tweaking up the gearbox to overdrive nuts & bolts as there seems to be a bit of seepage here? Apart from to the casing or threads can I damage the OD by over tightening these? Quote Link to post Share on other sites
Tony Millward Posted October 13, 2013 Report Share Posted October 13, 2013 Hi David, before you go tweaking nuts up check if oil is coming out of the selector shafts. Mine was also showing oil around the plate on the bottom of the overdrive and I thought it was leaking. It turns out that the O rings on the selector shafts were badly worn and the oil was running down onto the overdrive base plate. To cure the shafts leaking I tried all sorts of O rings of differing sizes and none worked. I eventually had some O rings made with a square cross section. These fitted into the recess's where the normal O rings fit and they sealed perfectly. Cheers Tony Quote Link to post Share on other sites
smizgals Posted October 13, 2013 Report Share Posted October 13, 2013 David, I agree with Tony, although I replaced mine with O rings from Moss that do the job. Stan Quote Link to post Share on other sites
Davidw Posted October 13, 2013 Author Report Share Posted October 13, 2013 Forgive my ignorance, but are the selector shafts the long rods on top of the box. Quote Link to post Share on other sites
Jersey Royal Posted October 13, 2013 Report Share Posted October 13, 2013 Forgive my ignorance, but are the selector shafts the long rods on top of the box. Yes they are. If you follow them back into the casing you will see a plate that the three rods go through, the seals are behind this plate. Look at this site and scroll down 3/4 of the way you will see the seals http://www.buckeyetriumphs.org/technical/Gearbox/GearboxCover/GearboxCover.htm Cheers Guy Quote Link to post Share on other sites
Davidw Posted October 14, 2013 Author Report Share Posted October 14, 2013 Many thanks, both of you. Will have look next weekend. Quote Link to post Share on other sites
Davidw Posted December 14, 2013 Author Report Share Posted December 14, 2013 Finally changed the seals and the box is back in. Other jobs preclude a test drive for some weeks. Will repost back after test drive which is likely to several weeks away. Quote Link to post Share on other sites
bobrogg Posted December 19, 2013 Report Share Posted December 19, 2013 I'll need to perform this job soon on my car. how long did it take you from start to finish? what was the level of difficulty? Thanks, Bob Quote Link to post Share on other sites
bobrogg Posted December 20, 2013 Report Share Posted December 20, 2013 I do not have a car lift so I am looking for the best practice to check and fill the gearbox oil level without resorting to removing the interior Quote Link to post Share on other sites
Tony Millward Posted December 20, 2013 Report Share Posted December 20, 2013 Hi Bob, Many of us have cut a large hole in the side of the tunnel adjacent to where the gearbox filler plug is. The size of the hole is the same as the big rubber bung (3"?) that is fitted in the floor, and a spare rubber bung was used to seal the hole. I don't have a photo unfortunately to show you, maybe someone else has?. Cheers Tony Quote Link to post Share on other sites
ianhoward Posted December 20, 2013 Report Share Posted December 20, 2013 Bob Further to Tony's above response, if it is just a matter of draining/refilling the gearbox, this can be done from underneath (though a little awkward - however, as always 'safety first' in securing the car on axle stands etc.!!!
