Wedge List / Re: Front Spindle Nut/Hub Adjusting Nut Retainer
« Last post by Major Tom on October 02, 2019, 06:44:54 PM »
If I recall - I took the old one to Home Despot and matched the

thread . They had crown or castle nuts that fit for a buck or two. I

might be wrong on the despot,  it might have been ACE Hardware, they

have a vast assortment of hardware one-off. Still it was a standard

thread, and common.



Yeah, most likely ACE

Wedge List / Front Spindle Nut/Hub Adjusting Nut Retainer
« Last post by "WILLIAM SMITH" on October 02, 2019, 05:48:57 PM »
One of the crown shaped, thin metal retainers (P/N 21H5129) for the nut that

holds and adjusts the torque on the bearings front hubs of my TR7 has become

mangled.  I have checked the big three Triumphs parts suppliers, and a few

others but, if they show it at all, they say it's no longer available.  The

Wedge cross Reference list doesn't cover this item either.  Dorman shows a

number of various sized retainers that look like those on the TR7 and list

the auto applications they fit, but they don't show any specifically FOR the

TR7.



 



Has anyone else encountered this, and if so, how did you resolve the issue?



 



From where were you able to source the retainer?



 



Has anyone been able to find a regular castle nut that will fit the TR7, and

if so, what size?



 



Any suggestions will be appreciated.



 



Thanks,



Bill Smith

Terry, I probably have use for the remains (the small miscellaneous stuff) of
your TR-7 as I am well along with the restoration of my 80 model. Seems like I
am forever scrounging parts from the two real Junkers I have, so I could
probably use yours. For the axel and rear end, I have no need.

I do have a trailer for transport and I live south of you by about 30 miles. I
will try giving you a call.



As an added thought, I will be leaving for the Nationals this coming Saturday
and should there be a need, I have space available on my car haul trailer.

Wedge List / TR7 rear axle
« Last post by Terry Merrell on September 29, 2019, 05:30:10 PM »
Good afternoon,



I have a 1978 TR7 FHC with automatic gearbox I am parting out. I am keeping

everything associated with the auto box except the rear axle and driveshaft.

It is the banjo type axle like the 4 speed uses. The difference is it uses a

3.27 to 1 ratio. As the whole axle was driven by the auto box (59,000 miles)

it likely is in better condition than a 4 speed would with similar usage. My

understanding is it is the same center section (again different ratio) as a

late Spitfire and Midget. If you installed this in place of the 4 speed unit,

your top end engine revolutions would be lower. It would be slower off the

line but be a better and quieter highway cruiser.



Ibll pull the center section and ship it for $100 plus shipping or if you

can come pick it up, you can take the whole axle including brake drums for

$100. Ibll throw in the driveshaft as well if you pick it up. My goal is to

scrap the leftovers before the end of October. Ibll hold onto the center

section but the axle housing and shafts will be gone when I take the car to

the scrap yard if no one takes it before.



I could probably bring it to you if you are local.



I am in St. Louis, MO.

Wedge List / 5-speed rear axle end play
« Last post by "peternuss" on September 28, 2019, 11:32:25 AM »
That doesn't look normal to me.  At least none of the rear ends laying

around here have that much slop.  For the price of a cover plate gasket, I'd

open up the rear end housing and check the wear on the cross pin and axle

ends.  A simple cross pin replacement might get rid of a lot of the play if

it's worn.  (you could flip it end for end, rotate it 90 degrees and have a

new hole drilled in it also)  At worst I guess you could have wear on the

cross pin and carrier holes that hold the cross pin.  Anyway, it's something

I'd check out because nothing get better with the axles slopping around in the

rear end.



   If you go that route I'd also remove the cluster gears and spider gears and

check out the thrust washer UKC964, I've found those broken on a couple of

rear ends, and 102801 fiber thrust washers that see wear also.  The UKC964

comes in different sizes to insure a good fit, but, all the sizes are not

available, but, you can buy larger ones and fit them to your application.

One is inclined to ask if this has been progressing over time or has it been

like this for quite a while?B  If it is getting worse it needs to be

addressed.

But you don't know since you have only just found this, right?

Good clarification. When I don't pull or push on it by hand, and just spin the

other wheel with a dial gauge on this side, I see about 5 thousandths

runout..



I initially just wanted to measure runout, in case the axle was bent or

something. The pulling and pushing for the video was to see how much play

there really was. The total play is more than 5 thousandths.
