Stationary M25 Traveller Posted August 10, 2014 Share Posted August 10, 2014 Does anyone in Kent or Essex have a cranked bit of tube/pipe they use to suck oil from a 5-speed box in-situ ? Driving me crazy here !!!!! Edited by - sm25t on 10 Aug 2014 16:29:13 Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted August 10, 2014 Author Share Posted August 10, 2014 Considering another approach ..... removing top cover of gearbx. Bolts all out. Is cover stuck on with an extruded sealant, or a conventional gasket ? Don't want to lever it off only to find I have to chisel bits of sealant off, which will then fall into the gearbox !!

tony pashley Posted August 10, 2014 Share Posted August 10, 2014 Going purely from memory, mine had a narrow cork gasket; I don't recall any issue with sealant or goop to fall into the box - do cork gaskets normally use sealants?. (That's with the regular pressed steel cover.) I subsequently replaced it with an alloy one (the cover that is, from James Whiting, I think) with a threading for a breather - which is also of a big enough diameter to fill it through and (just about) suck most of the oil out if necessary. Getting all of the screws out is the fiddly bit. ps of all the things that could distract me from watching a bike race - it's a gearbox gasket…!

Stationary M25 Traveller Posted August 10, 2014 Author Share Posted August 10, 2014 Thanks Tony. I have got all the screws out .... just poised to crack the grip of the cover with a screwdriver .... Anyone else confirm this .... ? 😶🌫️ Link to comment Share on other sites More sharing options...
Myles Posted August 10, 2014 Share Posted August 10, 2014 No, but ten years after BGH fitted their custom top-cover (with dip stick) without explicit authorisation from me, I was finally glad of it last week when I was able to extract all the oil and refill through the dipstick Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted August 10, 2014 Author Share Posted August 10, 2014 After some advice from Phil Stewart ( 😶🌫️), I am about to prise the top off. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 10, 2014 Member Share Posted August 10, 2014 Can't remember what mine had but it wasn't additional sealant. You'll be fine. Jonathan Link to comment Share on other sites More sharing options...
Paul Deslandes Posted August 10, 2014 Share Posted August 10, 2014 usually a paper gasket unless something else has been added. If you're careful you might be able to reuse it. Link to comment Share on other sites More sharing options...
myothercarsa2cv Posted August 10, 2014 Share Posted August 10, 2014 Did you figure it out in the end Ian? I once popped the top off the 2CV gearbox and a ball bearing whistled past my face! Caught me by surprise. Fortunately the box turned out to be dead anyway but I now have a fear of such things! P.s. Do you have a hole in the side skin for easy access?

Martin J Posted August 10, 2014 Share Posted August 10, 2014 It would be so much easier if a drain plug was fitted on the 5 speeder. I suppose they reckon it isn't needed as the oil doesn't degrade as unlike engine oil, it isn't exposed to the combustion process. The job I hate most is checking & topping up the gearbox oil on the 7. If Ian can prove it works sucking the oil out from the cover plate, I might do it one day otherwise the oil is in there until the box comes out of the car.

Stationary M25 Traveller Posted August 10, 2014 Author Share Posted August 10, 2014 Thanks all. Job done. I look like I have been fighting with a basket of kittens ..... reaching under bulkhead to undo the bilts for the top plate ..... what a battle ! Thanks Phil for giving me the confidence There is a flat under the gearbox ... looks like a place for a drain ? Can't make a hole in the tunnel side wall as I have a diagonal chassis member right beside the fill plug ! 9 Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted August 10, 2014 Author Share Posted August 10, 2014 By the way .... you don't need to remove the fill/level plug as ... on my SV at least ... I can see the inside of the hole ref oil level ! Link to comment Share on other sites More sharing options...
Martin J Posted August 10, 2014 Share Posted August 10, 2014 Well done. Top tip I got from Richard Young a couple of years ago....the gear shift was becoming sticky & pushing down for reverse was impossible on my car. I placed some newspaper under the car & poked the spout of an oil can down the gear stick gaiter & gave it a good soaking of duck oil. This instantly freed up the sticky selector & has been perfect ever since. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted August 10, 2014 Author Share Posted August 10, 2014 Having previously dealt with John Birrell's sticky shift, I removed the tunnel top and undid the three bolts to remove the plate that retains the gear lever. Good dose of grease and ACF50. Link to comment Share on other sites More sharing options...
Mankee Posted August 10, 2014 Share Posted August 10, 2014 Quoting SM25T: There is a flat under the gearbox ... looks like a place for a drain ? My latest gearbox has this modification. I used a Peugeot/Citroen magnetic drain plug from an MA gearbox. Can't remember the exact thread size. The other side of the flat is the standard magnet, which needs to be removed. There's not that much material thickness, but enough for the plug to be wound in a few threads and I've used a dowty seal plus PTFE tape. Not done a full leak test yet as its sat on the garage floor, but it's torqued up to 25nm fine and I will be using a vented top cover anyway.

Titanium7 Posted August 10, 2014 Share Posted August 10, 2014 Just refilled my 6speed using a length of clear soft PVC tubing with a small funnel at the top. Used a length of welding rod about 8" long with a 90 degree 1.5 " bend at one end pushed inside the tube to enable entry into the fill hole. Job done in 30minutes.

myothercarsa2cv Posted August 10, 2014 Share Posted August 10, 2014 Ref Ian's post mentioning my sticky shift, that was due to a rusty spherical bearing... Do check that before pulling the box out The top plate with the filler cap and a drain plug mod would definitely be the way forward. Link to comment Share on other sites More sharing options...

One of the best modifications I have done to the car. Link to comment Share on other sites More sharing options...
elie boone Posted August 11, 2014 Share Posted August 11, 2014 I have drilled and tapped the flat part with the gearbox in situ, with the g.box oil still in the box I drilled a 6.5mm hole to accept a M8 bolt. When the oil runs out of the hole it will take all swarf that might be left with it. Even when you tap the tread there is no swarf coming in the engine.

Yes, that would need a long tap... but how about the gearbox? ;-) Jonathan Link to comment Share on other sites More sharing options...
