jbs Posted May 9, 2013 Share Posted May 9, 2013 Hi All, Later this year I will be putting in a stumpy R380 gearbox and a recon disco 'T' box in my 90, I already have the disco 'T' box and am very happy with what It does for me, but it's getting a little old now and the backlash etc is on the large side for me, so I'll have the cash saved up to replace those and the diffs complete(Diffs will be replaced with 4 pin pegged diffs), However I would like to put an oil cooler on my new gearbox and am wondering how strong the oil pump is on it as I'd like to mount the oil cooler on the underside of the drivers wing top under the aperture where the LHD heater intake would be, I don't have the room in behind the front of the grill as not only do I have a full width intercooler, I also have a milemarker winch there too-hence why I was asking about the drivers side wing top? TIA John Quote Link to comment Share on other sites More sharing options...
Maverik Posted May 9, 2013 Share Posted May 9, 2013 Why do you want to put a cooler in? Any particular reason? Quote Link to comment Share on other sites More sharing options...
jbs Posted May 9, 2013 Author Share Posted May 9, 2013 I think that with me doing a lot of mileage in my 90-It's my daily driver and I do-do a fair bit of motorway mileage, it may prolong the life of the G-box and not cook the MTF in it.

mmgemini Posted May 9, 2013 Share Posted May 9, 2013 A very simple job. You need the oil pipe take off for the gearbox. Then the Wolf oil pipes to the oil cooler. Land Rover fit quite a large gearbox oil cooler in front of the radiator matrix but I fitted a small cooler onto the front panel below the radiator. The biggest problem I had was getting the flexi pipes and connections. Pirtec were not at all interested in helping. Quote Link to comment Share on other sites More sharing options...
jbs Posted May 9, 2013 Author Share Posted May 9, 2013 Mike, Thank you for your input Would by any chance the oil pump in the gearbox be man enough to pump it up to a cooler under the drivers side wing top, And thanks for the tip about pirtek too John Quote Link to comment Share on other sites More sharing options...
mmgemini Posted May 9, 2013 Share Posted May 9, 2013 That John I don't know. Maybe Ashcrofts could answer that one. I would be more concerened about oil drain back though. Have you seen the bog brush one fitted to the Range Rover auto and the RoW Discovery. It justs sits on the front crossmember. I originally fitted the cooler to teduce the seatbox temperature on our trips. Never noticed any difference though. Quote Link to comment Share on other sites More sharing options...

Jode Posted May 10, 2013 Share Posted May 10, 2013 John - Have you already sourced the oil cooler pipe to gearbox fitting (FTC2104)? Did you buy new or a used part? If you got a used part I'd be keen to learn if your supplier has another one, as I'm unable to source a used part in this part of the world (and I'd like to fit a cooler).

mmgemini Posted May 10, 2013 Share Posted May 10, 2013 Jode there is a problem with the pipes. Land Rover fit IIRC an 18mm fitting. AFAIK oil coolers are still made in BSP. It was getting the fitting from metric to BSP where I had a problem. Where did you get the part number for the pipe ? I have it as LESR2749 Both pipes are the same.I also have the bracket part numbes if you need them Quote Link to comment Share on other sites More sharing options...
jbs Posted May 10, 2013 Author Share Posted May 10, 2013 Hi Jode, No I haven't sourced one yet but will do so when I get my new gearbox-Sorry, The one I've just found Is a little on the expensive side-so sit down when you click on the link: http://www.shop4autoparts.net/Defender/Gearbox/R380/Extension-Case-&-Oil-Pump/HOUSING_OIL_COOLER_THERMO_R380.html Perhaps the best thing would be to give Ashcrofts an e-mail and see what they can do for you. And Mike Thanks for the heads up on the size of the fitting-seems daft that they've done that!! HTH John Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted May 10, 2013 Share Posted May 10, 2013 Ashcrofts do the full kit IIRC for £245. Not that I've been looking, mind Mo Quote Link to comment Share on other sites More sharing options...

And Mike Thanks for the heads up on the size of the fitting-seems daft that they've done that!! HTH John HOW MUCH ! ! Dave Ashcroft dropped one into my hand. No it's not Land Rover that's daft. It's the people at Brussles that change the legislation to suit. Theought my working life I've had, BSW, BSF, Then UNC and UNF. Then in the 1970's Metric was all the rage. My Astra engine had metric on the block and BSP for the pipes unions. You'll find the 200Tdi has BSP unions but the 300Tdi was changed to metric Quote Link to comment Share on other sites More sharing options...
jbs Posted May 11, 2013 Author Share Posted May 11, 2013 Mike, I did say sit down when you open the link up lol, shame L/R didn't stay the same with the 300 as the 200. Quote Link to comment Share on other sites More sharing options...

HTH John John - I've checked out the Ashcroft model, and that is certainly less costly than buying the LR itting I mentioned plus the hoses/pipes and cooler (I'm looking at a Derale cooler from the US as they're available at a better price vis-a-vis Ashcroft's). My problem is finding the pipe interface (mentioned above) that bolts to the R380 in lieu of the 'thermostat housing', which is an oil return loop that is fit to the box when an oil cooler is NOT fit.

Yes. Only the one adaptor. Two pipes along the gearbox and engine sump. Quote Link to comment Share on other sites More sharing options...

Jode, Many thanks for that, I've still a while to go yet before I get the total funds for the drive train and will be putting a cooler on it as I explained above-I've changed an LT77's gearbox oil when I first got the vehicle and on that occasion the oil had the smell of being burnt to it, Perhaps It was the previous owners idea of maintenance to not change the oil in it-I do mine on every service(All the oils-Engine, gearbox, diffs etc.) but seeing as a lot of the mileage I do in mine is long distance then I'd like to alleviate that possibility of it over heating as we all know It's not good for the seals or even the bearings to get over heated-they fail and usually at the most inopportune moments too, and I'd like to have it last as long as possible seeing as I'm spending a good chunk of cash on the stumpy R380 that I really want under my truck, It maybe me over engineering the situation by having the cooler on the box but I tend to do this with all of my trucks equipment be it mechanical or otherwise-This has been for me a well proven path to tread as I very rarely get let down by a break down.

Jode Posted May 14, 2013 Share Posted May 14, 2013 John - Certainly the Ashcroft cooler is the least expensive cooler 'kit' for the R380 that I have found - in fact, I've only found that unit plus the standard LR cooler fit to the 'wolf'. It is possible to use the bottle brush cooler that was fit to some discos and RRs, but for my money I would prefer a larger volume cooler than those. Gearbox coolers are quite common in the US (automatic boxes can get quite hot), and it's possible to find on US websites quite a range of kits based on coolers of various geometry fit with flexible hoses. Issues that I found significant when trying to source something for the 110 included hose lengths (which of course depend upon the placement of the cooler itself), hose diameter (which can affect coolant flow rate) and cooler construction (my investigations suggest that stacked alu. plate coolers have the right robustness for off-road driving). My bias would be to fix the cooler to the A-bars in front of the radiator (as was done with the 'wolf'), as I figure that this is reasonably out of harm's way when off-roading, and as it was done by LR itself it will probably not compromise engine cooling excessively. My cooler plans continually come to nought however because of an inability to find the adapter needed for connecting the coller pipes to the R380 (pickey shown below).... I've even sent mails to companies listed on ebay as gearbox specialists.... Quote Link to comment Share on other sites More sharing options...
tacr2man Posted May 14, 2013 Share Posted May 14, 2013 These coolers will do the job without any bother , they are designed for engine oil cooling , I have on a 90 . its an auto but will cope with manual box oil flow without any problem . http://www.ebay.co.uk/itm/MITSUBISHI-PAJERO-SHOGUN-OIL-COOLER-/321105586133?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4ac36267d5 While you are at it change oil to Redline full synthetic , will handle the higher temps if reached much better , not cheap but good insurance . Usual disclaimers re Redline HTSH re redline oil capabilities if you want more info then pm as dont want to type big spiel on here (spam?)
