Triumph TR6 - Rear hub/drive shaft removal
|I am removing the left rear hub/drive shaft. I have removed the 4 bolts and nuts from the inner flange, removed the brake drum, as well as the 6 nyloc nuts securing the hub bearing housing to the trailing arm. According to the manual (cd) that is all that is required and the hub/drive shaft should pull out without disturbing the brake assembly. However I can't seem to separate the brake assembly from the hub bearing housing. Any suggestions would be appreciated.|
You are there. You just need to get out the friendly persuader.
You also might try a long screwdriver between the brake back plate and the hub.
Persuasion is the word for the day.
How do the studs look from the trailing arm? any "strip out"?
GEEESSS Pete, pretty soon you are going to be doing this stuff in your sleep:)
Buy the way, if you find the hub difficult to turn by hand do not worry about it....that is normal.
|Pete - a few comments...|
Be careful that you do not separate the hub shaft at the spline. There are very small needle bearings that I have heard are a real pain to get back installed.
After folding the dust cover back towards the outer hub and taping with duct tape I used some scrap electrical wire to tie the inner flange to the outer assembly and then removed from the trailing arm. Some say that it's easier to push out from under the car.
If you remove the brake shoes you may be able to move the backing plate to the side without loosening the brake hose. Saves bleeding the brakes again.
I just had my RH hub rebuilt by Scott Howell at High Point Imports in NC. for $165.00 plus return postage. tel 336-884-1455 email@example.com He does not have a website. Great guy to work with. Hub looked new when I got it back.
what Rick said, it should just pull out. I'm off for the winter in about two weeks, I'd love to come and give you a hand if there's any work left to do.
Not sure what and where these needle bearings are. The spline itself does not have neddle bearings. Where are you talking lad?
Chris, Pete would probably let you replace the front timing chain cover gasket. Take over a big hammer with you:)
|Rick, et al the pursuader did a fine job, and the shaft came out no problemo. Thanks all for your comments, and no I do not see any needle bearings at the spline. Also, Rick the studs are in A1 shape!!|
I was cautioned by a full time LBC mechanic to take precautions to not let the axle shafts separate inside the gaiter because of the problem with getting the needle(?) bearings reinstalled. My original Leyland Repair Operational Manual does not show this breakdown on page 51-16, nor does it address this on pages 64-3 & 4.
If this is in error then I received faulty information. However, this mechanic has not yet mis-informed me. Have you separated the halves? Good info for future reference.
While on the subject, I have read of many disasters in taking the hub to a local machine shop for repair only to end up with a damaged hub or broken wheel flange.
Sorry Bob but I think he gave you wrong info ( for a TR6).
I have had the rear out of my 6 many times and obviously I installed it on my total restoration.
There are no needle bearings in the rear of the car....well...OK...yes in the UJs themselves. They do not count as you are going to replace them anyway if you take them apart. Now that I think about it, are they not called roller bearings inside a UJ?
The spline (the sliding joint) is just as I called it a spline. There is a larger "key" spline so it can not be put back together incorrectly. It should be disassembled for re-greasing.
Bob there could be other LBC that have needle bearings in the back end but not a TR6.
No as for the hubs, there COULD be needle bearings in there ( I would put money down that there are not) as I have never taken on apart and never plan to. I fully agree, take the hub to someone who knows what he is doing.
A note to Pete: replace all nylock nuts with new ones and use LOCTITE on the threads for reassembly.
Pete glad you got it out. Good to hear about your studs. Just remember when doing the re-install that torque is 12LBS....If I recall correctly:)
Also since you are there, have a close look at the brakes. Kinda like an Alistair thing " one job leads to another":)
|Thanks for the info, Pete.|
It's interesting that the manual does not address this spline.
|Rick, that should be - Thanks for the info.|
|Pete, I know I sound like an echo but, 12LBS!!!|
I know, I torqued to the 13-14lbs that my manual stated
an striped the aluminum threads and then had to do 2 or 3 Helicoils to repair the damage.
Bob, maybe what your mechanic was refering to was how
tricky it can be getting the half shafts lined up perfectly so they slide together. I remember fooling
with them for awhile before the alinement was perfect.
|Actually, Mr. Selby may have bearings in his axle shafts but they would be ball bearings, not needle bearings. Revington TR has uprated hub and shaft asseblies that use a 4 ball bearing "rolling spline" down the length of the drive shaft. So it would be correct to say that yes, there may be some bearings in there. |
Having said that, I doubt that this is the case in this instance. They are really expensive and im sure you would know if you had that type installed.
|Yes 12 lbs, 12 lbs, 12lbs. I will post a note on the wheel well. Thanks Chris. Actually Chris, I am in no hurry to do this, as I have all winter (unlike some of our southern friends). So let me know when you can pop over.|
It so turns out that the "play" is not in the u joints at all. They are in good shape. The play is in the diff., so looks like I will remove the diff., get an estinate on repair or replace.
|I'll ask Lee for clarification on the bearings in the next few days. |
In the "Sunny South" we enjoy our LBC all year long. Thanksgiving afternoon I carried the teenage granddaughters for a ride. Yesterday, we had a nice ride to a local winery with some folks from California. Tomorrow, we also have a ride planned. Local mid-day temperature is 60 F or so. Yes, the hood is down and we love it! On December 30th we will meet the Georgia Triumph Association on their Polar Bear Run to Barber Vintage Motorsports Museum. www.barbermuseum.org
