Barry Kemp Posted February 9, 2018 Report Share Posted February 9, 2018 My Herald is leaking oil from both sides of the the diff /driveshafts. What is involved in replacing the oil seals? I can't find much info about this. Do I need any special tools to do this? Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 9, 2018 Report Share Posted February 9, 2018 Need to drop the drive shaft flange , and use allen hex key through the bolt holes to remove the short shafts They are not the easiest thing to strip, the circlip is a pig to remove , often have to chop it to release it. Get some new ones See notes in darrens post earlier. Getting the shaft out of the bearing can be tight , you need to grip the bearing in a good vice and drive the shaft oit Once shaft is out you can prise the old seal out the hsg, Refitting is much easier Pete Link to comment Share on other sites More sharing options...

I was half hoping the bearing would be OK to re-use, but in the end decided that the extra cost was worth doing. One of the issues I have come across is that if you drive a bearing on its outer housing, even if you have no intention to reuse it, I have actually had them so tight the bearing had crushed the cage and the outer came off!. Which can leave just the inner race often with no access behind it, then you are into split the inner race territory, hours with a tiny grinder and cold chisel!.

Pete Lewis Posted February 10, 2018 Report Share Posted February 10, 2018 If this becomes beyond the diy possiblility, There used to be some available as a exchange assembly but I dont see any suppliers offering this now May be worth a call to dave at canley Pete Link to comment Share on other sites More sharing options...
Barry Kemp Posted February 10, 2018 Author Report Share Posted February 10, 2018 Ok so now you've got me doubting my resolve ! There has been a slight leak from the seals for years and years but I thought I'd correct this as I'd taken the driveshafts/vertical links off to clean them up & paint them. I'm tempted to ignore the leak now! How much of this is done under the car and how much is done on the bench? For example is the circlip removed on the bench?

Pete Lewis Posted February 10, 2018 Report Share Posted February 10, 2018 Just the socket cap screws from underneath, the whole shaft and housing just pull out And work on the bench.with the assy. In comfort. Strong tea is obligatory Its a wire clip has no eyes for circlip pliers, hence if you cant get it to open a chop witha sharp cisel or similar removes it in two bits Always replace with new what ever means of removal is used. Its a good job when done, just its an hours job that could take all day You may be luck and it all pops apart Live in hope Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted February 10, 2018 Report Share Posted February 10, 2018 I'll post a couple of pics to let you see what you'll be looking at. Four allen screws remove these side assemblies, then the circlip and bearing can be removed in leisure on the bench. A relatively simple, straightforward job. I was able to tap the bearings off once the circlip had been removed and the new ones were pressed back on, both actions with the aid of a simple bench vice taking care not to damage the ends of the shafts.

68vitesse Posted February 10, 2018 Report Share Posted February 10, 2018 Did this job on my Vitesse last year, http://forum.tssc.org.uk/topic/1918-diff-inner-axle-shafts/, bought bearings, standard metric size readily available, and seals from specialist suppliers. Do not know if the parts used on my Vitesse diff would fit your Herald one. Regards Paul Link to comment Share on other sites More sharing options...
Barry Kemp Posted February 12, 2018 Author Report Share Posted February 12, 2018 Thanks guys , that's really helpful - especially the photos. I shall start on it this week and let you know how things go. Regards, Barry Link to comment Share on other sites More sharing options...
Andrew Posted February 12, 2018 Report Share Posted February 12, 2018 Hi Barry replaced all three seals in my Herald diff over the Christmas period, it is really quite straightforward. Treat yourself to a bearing puller from machine mart, it is worth every penny. Whereabouts in the country are you. If you are close I will give you a hand. regards Andrew Link to comment Share on other sites More sharing options...

Darren Groves Posted February 14, 2018 Report Share Posted February 14, 2018 If you have access to a press then getting the bearing off is pretty easy, just a few minutes either side. I'm sure a local garage would do it for little money if you don't know someone who has one. If you are replacing the circlips, beware if you have ordered them from a certain supplier in Lincoln as they were too big and just dropped into place: Darren Link to comment Share on other sites More sharing options...
Barry Kemp Posted February 15, 2018 Author Report Share Posted February 15, 2018 So, I took the shaft to my local garage to remove the bearing. They couldn't get the bearing off but bent the flange! My next trip was to a private address with a good old fashioned engineer . He got the bearing off with his big press but the bearing shattered. Fortunately he managed to flatten the bent flange on his press - so that saved me a bit of money. The oil seal behind the bearing was made of leather...it reminded me of just how old the car is! I'm guessing the new bearing won't go back on without using a press? Can't wait to do the other side! I still love the old girl though! Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 15, 2018 Report Share Posted February 15, 2018 I said strong tea, Do make sure the flange is flat, give it a run with a flat file and test flatness on peice of glass Any runout on the flange will upset the driveshaft and uj You dont want to start an extra problem Link to comment Share on other sites More sharing options...
Colin Lindsay Posted February 15, 2018 Report Share Posted February 15, 2018 +1 on that, Pete. Any distortion will give rise to annoying vibrations when driving. Barry - I replaced mine with very little effort, just a bench vice and a bit of pressing by hand; and possibly some light drifting with a hammer and wood block. Nothing requiring tons of pressure.

Barry Kemp Posted February 15, 2018 Author Report Share Posted February 15, 2018 I don't understand why there would be such a massive difference in the effort needed to get the bearings off. Other than the fact that mine had never been changed, so was on there for 49 years! Link to comment Share on other sites More sharing options...
Andrew Posted February 15, 2018 Report Share Posted February 15, 2018 Hi Barry. get a bit of pipe that fits over your shaft and rests on the inner race of the bearing and a few light knocks with a hammer and it will drift on easily andrew Link to comment Share on other sites More sharing options...

When doing the other side, add some heat when it's under pressure on the press, it should let go without bending the flange. Darren Link to comment Share on other sites More sharing options...
