puiwit Posted February 15, 2008 Share Posted February 15, 2008 How do I install new axle breathers for a lr defender 90 td5. I have to drill ø8,8mm and cut the G1/8" thread in the existing hole in the axle. 1) Is the wall thickness enought for the thread in the axle? 2) Do you recommend to open the axle for this job to clean the emerging swarf? 3) Please give me your advice to protect the new plug-connector. Thank you for your effort and kind regards. Carsten Quote Link to comment Share on other sites More sharing options...
Lars L Posted February 15, 2008 Share Posted February 15, 2008 Excuse me for asking, but isn't there already a breather in each of your axles? And threaded holes you can use? It certainly is in mine - Rover front and Salisbury rear. Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted February 15, 2008 Share Posted February 15, 2008 I thought td5 axles were already fitted with push fit connectors? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 15, 2008 Share Posted February 15, 2008 I think he's right, in which case I'd just get a push-fit 90 degree adapter and call it job done. I drilled and tapped my axles using great care and a well greased tap to catch the swarf. Quote Link to comment Share on other sites More sharing options...
Mr Bean Posted February 15, 2008 Share Posted February 15, 2008 If your axle is sealed why would you need a breather? I thought the idea was to allow the exsisting breather to be higher than the wading depth so to avoid water getting in your axels. Quote Link to comment Share on other sites More sharing options...
Top90 Posted February 15, 2008 Share Posted February 15, 2008 My understanding is that a hot axle meets cold water, air inside contracts and if sealed it will suck water in through the seals. TD5 axles should have the tubes already. you just need to extend them to under the bonnet or up the snorkle. Should not need to drill any holes.

FridgeFreezer Posted February 15, 2008 Share Posted February 15, 2008 What Top90 said - if the system is sealed it will suck water in through oil seals, or when it warms up it will eject oil through the oil seals. Neither is desirable. Quote Link to comment Share on other sites More sharing options...
istruggle2gate11 Posted February 15, 2008 Share Posted February 15, 2008 I drilled and tapped my axles using great care and a well greased tap to catch the swarf. A spiral flute tap eliminates 99% of swarf removal problems. IIRC all Land Rover axles have been fitted with breathers, even the early ones, remove the bell type breather and fit the 6mm push fits (1/8" gas) TD5's do have push fit breathers, a section of tube with a hole in the side would make the ideal protection.

SteveG Posted February 15, 2008 Share Posted February 15, 2008 As said above, TD5's just extend or replace the existing 6mm OD tubing that goes into axle push fits. I ran two new tubes and use 'Y' connector to take axle and transmission breathers up snorkel. Ian, username Porny, can supply some small profile stainless steel 90 degree push fits if you are concerned about knocking them off. I didn't bother with a 90 bend and I've had mine for about 2 years now with no issues with knocking tubes off.. Cheers Steve Quote Link to comment Share on other sites More sharing options...
roken Posted March 13, 2008 Share Posted March 13, 2008 My understanding is that a hot axle meets cold water, air inside contracts and if sealed it will suck water in through the seals.TD5 axles should have the tubes already. you just need to extend them to under the bonnet or up the snorkle. Should not need to drill any holes. Word of advice: Make sure that the breather hoses do not end near (with "near" i mean "next to") the snorkle air intake. Apparently the snorkle can cause a vacuum in the hoses, sucking out fluids that are really more useful in the gearbox or axles than the air filter. Got this from a mechanic when buying a wader kit... he'd apparently had a client coming in with perfectly aligned breather hoses / snorkle and an air filter soaked in gearbox oil. Haven't fitted my kit yet, btw... guess I'll start a "Can someone please help me out of the mess i have made?" or a "Where is this supposed to go?" thread soon.

LandyManLuke Posted March 13, 2008 Share Posted March 13, 2008 what a load of rubbish!! Given the relative cross sections of the snorkle and the breather pipes, the pressure drop you'd see at the breather pipe would be negligable. ok, if you block the snorkel you might have a viable situation, but then it'll stall the engine, or leak from somewhere else. I've had my axle breathers in the top of my snorkle for about 3 years, no problems what so ever. Quote Link to comment Share on other sites More sharing options...

LandyManLuke Posted March 13, 2008 Share Posted March 13, 2008 One of those 'mate of a mate heard down the pub about someone else's brother's mechanic' stories? By all means, take the advice, it won't do any harm. like wise, i'm not running outside to re-route my breathers to prevent impending doom.

Gromit Posted March 13, 2008 Share Posted March 13, 2008 I've heard similar stories from several people, so I would not discard it as rubbish but consider it good advice! Given that the axle end of the breather is in air, not oil, it'd have a hard time sucking oil, unless of course the truck was on its roof Quote Link to comment Share on other sites More sharing options...
Guest mortus Posted March 13, 2008 Share Posted March 13, 2008 i agree with luke, the vacuum created would be negligible, and would not suck oil up the small pipe to your snorkel. Quote Link to comment Share on other sites More sharing options...

No, not one of those stories, a mate who found his air filter quite oily when doing a service. He decided to move the breathers to the outside of his snorkel instead of having them on the inside, and never had the problem again. On the other hand, I do understand what you guys are saying about the effect being unlikely, and I have to agree theoretically, but still, better safe than sorry.
