Diff parts.

[Richard Young]

Evening all, (TR6 resto)

Got the diff taken apart and now thinking about sourcing parts.Rimmers do a bearing kit incl. all bearings/seals....I know there are 'bearings' and 'bearings'...not sure what make Rimmers use)..would I be ok using them does one think?....or can someone recommend a source.

 

Thanks in advance

 

Richard.

Honestly?.??? Get rhp/ntn bearings from the usual sources.......

Hi Richard,

it would be wise to use top quality bearings. Moss have alternatives - one at £15 and the other at £75.

Guess which one would last longer. http://www.moss-europe.co.uk/shop-by-model/triumph/tr5-6/clutch-transmission-drivetrain/axles-differentials/rear-axle-b62f33.html

 

Compare the Rimmer prices with the Moss prices and see if there is an apparent quality difference,

Hi Richard,

 

Tom has got it right use RHP now owned by NSK who are an international manufacture or NTN etc. Do not use any cheap Moss or Rimmer bearings and as a guide only use ones that are properly marked on the outside. There are counterfeit brand name ones out there as well, its a mine field! In my view based on my own tool room engineering experience, its a job for a specialist of known performance because of the type of equipment required and the knowledge of how to use them as you are working to very close tolerances. I must stress this point as there has been a lot of threads on this subject where people have fallen foul, including some members in our group. Lastly are you certain that you do not need a new CW& P?

Thanks all for advice....minefield indeed.

Yes minefield, many have opinions, some experience in diff repair

and only very few swap between those different bearings when repair

and get reliable results from that.

 

If you remember that trouble of the V8 Simon you might come to the

conclusion that besides the bearings a lot else can go wrong.

 

Wrong preload for the bearings is bad and worse for the cheap bearings.

So many fails might be blamed on the bearing quality but are more

related to wrong settings and fitment.

 

For me myself I tend to use NTN or RHP like Tom recommended

-fit and forget-

But for some clubmates I did the job with the normal bearing sets.

That is a special situation because only the diff has to be removed

and I do the work for free. Than Cheap Charly makes sense, too.

 

If the repair has to be paid fully the more expensive quality bearings

do not play that role in the whole expense and should be preferred.

 

I never had a failure of the cheap ones but to be honest most people

drive their TRs only 1000 miles per year.

[Ford Prefect]

Moss only use Timken or NTN bearings in their diff rebuild kits and the 100422 bearing is the correct 15100SR/15245 bearing by Timken.

Rogers comments regarding difference in price of the carrier bearings is due to the expensive one being Timken and the other being NTN.

[Richard Young]

Thanks Andreas...very interesting comments and also input by Mr. Prefect.

I think I know which way to move on this now...or do I?

[Andy Moltu]

We use a guy in Leicester who used to rebuild the diff's for one of the TR suppliers (no names) but he stopped doing the work when the supplier insisted on supplying all the parts (the bearings he described as something out of a cheap washing machine) yet expected him to warranty the work!

 

Good TR diff bearings last a long time and saving a few pence at rebuild time is a false economy.

[GT6M]

Wot makes ye think that new bearings are needed

 

are they worn, scored or some thing else

If look good, and run silent wen cleaned up an spun up

then use the OE ones in Diff

 

Generally, a olde diff that stood for ages, an no turned owa,

then the rollers an race get stuk t,gether, and when parted, / turned, there is an indent left in race,and rollers

 

If they look ok, sound OK, then re use,

Thanks Roger....think will go with your advice (Moss) and take the higher value choice.(Timken).Never tackled a diff rebuild before but lots of info online and I think I can get my head round it all.I'm a piano engineer by trade so used to lots of detailed measuring etc... also Ed's rebuild pages are never far away.

Hi Richard,

not sure bit there may also be a Buckeye write up on it as well.
