Mr Blue Sky Posted July 23, 2017 Report Share Posted July 23, 2017 Hi everyone, As a newbie to the forum, I thought I'd share some photos of what came out of the axle when I was carrying out a service on the car. The oil was black and you could see a golden hue in places (brass?) but no other symptoms are evident. Welcome the thoughts of the forum on what I can expect to find when I take the diff cover off? Best wishes, Laurence Quote Link to post Share on other sites
Lebro Posted July 23, 2017 Report Share Posted July 23, 2017 (edited) Ouch I think you need to investigate further. Either a bearing has broken up, or some gears are missing some teeth (or part of) Bob. Edited July 23, 2017 by Lebro Quote Link to post Share on other sites
iain Posted July 23, 2017 Report Share Posted July 23, 2017 I don't think it's going to be pretty..... Quote Link to post Share on other sites
roger murray-evans Posted July 23, 2017 Report Share Posted July 23, 2017 Possibly the remains of a previously broken halfshaft that the repairer has not bothered to flush our? Roger M-E Quote Link to post Share on other sites
Motorsport Mickey Posted July 23, 2017 Report Share Posted July 23, 2017 I'm down for pinion teeth. Do a search using the search box top right, another sidescreen owner has a similar problem only about 3 weeks ago. Micky Quote Link to post Share on other sites
RogerH Posted July 24, 2017 Report Share Posted July 24, 2017 (edited) Hi Laurence, as Mick states something similar was reported a couple of weeks ago. Stan Foster and Kevo-6 (TR6's) have had big problems.

mjdearing Posted July 24, 2017 Report Share Posted July 24, 2017 Hi Laurence pm me if it turns out you need some parts' have saved good internals from Lockheed axles. Martin. Quote Link to post Share on other sites
Mr Blue Sky Posted July 24, 2017 Author Report Share Posted July 24, 2017 Hi guys, I knew TR's were tough, but this is just amazing! How this CWP ran without making any noise, is beyond me! I have attached a photo of the pinion which looks like it barely has a complete tooth. Strangely, the crown wheel is unmarked. The tiny little pieces I took out and posted last night are not of the same magnitude as the damage that can be seen here. Is the replacement of the CWP something that can be done in-situ or does the axle have to come out? Will check out the earlier posts on pinion damage and parts availability. Thanks everyone.

Ian Vincent Posted July 25, 2017 Report Share Posted July 25, 2017 I would say it has to be an axle out job. Rgds Ian Quote Link to post Share on other sites
Motorsport Mickey Posted July 25, 2017 Report Share Posted July 25, 2017 Axle out, just imagine those particles of shattered tooth suspended in a gloopy oil and where it's got...everywhere. It needs a thorough clean and a minute examination of the other gears etc inside, it's likely there is damage, it's just not easily visibly when everything's draped in EP90 !

Mr Blue Sky Posted July 27, 2017 Author Report Share Posted July 27, 2017 Hi All, just a quick update - I have found a replacement axle with a good diff and CW&P, no halfshafts or drums so will re-use mine. While I am at it; I will replace bearings and seals at the same time. Out of interest, does anyone have the manufacturers bearing and seal pt no's - i.e. the SKF/INA/Timken numbers?? Hopefully back on the road in a couple of weeks. Cheers, Quote Link to post Share on other sites
mjdearing Posted July 27, 2017 Report Share Posted July 27, 2017 Hi Laurence you will need a load of various sized shims for the pinion positioning and pre load settings and another load for crown wheel adjustment also don't forget the sun and planet shims as you won't get the backlash in spec on the crown wheel if the planet/suns are rattling about, a nice little project but can be very trying at times. hope I'm not telling you how to suck eggs all the best.

Alec Pringle Posted July 27, 2017 Report Share Posted July 27, 2017 Hi Laurence, as far as I can see from ancient scribbles, the wheel bearing is 206S. Diff bearings 16150/16283. Pinion bearings 31885/3120 head and 15100SR/15245 tail. Ransomes LJ30 or LJ30D for wheel also. Timken numbers of old, which may be superseded by now.

Hopefully back on the road in a couple of weeks. Cheers, Hub oil seals change with axle number. There are two different sizes. The dimension that changes is the internal one that runs on the hub spigot. Measure the diameter of the hub flange area that the seal runs on. I can then sort the number for you. Did this recently for Dan in Hawaii, (2long) so the info should be on the forum somewhere. Peter W Edited July 28, 2017 by BlueTR3A-5EKT Quote Link to post Share on other sites
Mr Blue Sky Posted July 28, 2017 Author Report Share Posted July 28, 2017 Thanks to everyone who chipped in with advice - really appreciated. Off to collect my replacement axle tomorrow. Will order bearings and seals once I have the hubs off. Thanks again, Laurence Quote Link to post Share on other sites
Ian Vincent Posted July 28, 2017 Report Share Posted July 28, 2017 Hi Laurence, As a matter of interest, how will you set the pinion depth? Do you have access to the special tool? When I did mine, I had a bu**er of a job getting that right and I wondered if there was a better way than I used. FWIW I used a piece of machined round silver steel bar held in the bottom of the bearing housings with a couple of hardwood discs - it was a bit Heath Robinson but eventually I got a repeatable dimension that I could trust.

Mr Blue Sky Posted July 28, 2017 Author Report Share Posted July 28, 2017 Ian, I read about the process to set pinion depth and crownwheel backlash and came to the conclusion that I'd get someone else to do that as I wasn't confident of getting it right. However, I have found an axle with a good CWP installed so will fit my brake backplates etc to that axle. Regards, Laurence Quote Link to post Share on other sites
