tr3a Bearings

[Richardtr3a]

I have often explained that the answer to the water pump question is to use the up rated unit from Racetorations.

 

However after nearly 25 years the bearings have failed. So I am reverting to my old pump wiith a grease nipple. I have a seal for the front and need high quality new bearings, not made in any far off distant land. My agricultural service store can probably locate some but without provenance.

 

Is there anyone left in the UK who makes bearings?

 

I do not want to change the water pump every 25 years.

 

Thanks Richard & H.

Hi Richard,

how many times will you be changing these in the future. !!!

 

If Simplybearings can't help then try these http://www.brt-bearings.com/ they only do quality bearings.

I found these Timken Numbers for the bearings on the web - equiv GHB110 & GHB111 - They need to be double checked as I have not read the numbers off a bearing.

 

OE Unipart/Triumph Pt No GHB111 GHB110
Timken

Inner Bearing Timken 07100S Cone
Inner Race Timken 07210X Cup
Outer Bearing Timken 03062 Cone

You measure bearings in the simplest possible way.

 

Diameter across, size of the hole in the middle, thickness.

 

Then you worry about the kind of seal..

 

All the TR bearings I have checked are simple Imperial sizes except the OD thrust, which is kind of weird and thin.

You can extend life of water pump significantly by

lowering the belt tension.

 

Should it start to squeak you can use belt dresser spray

and if still required increase belt tension a little bit.

Thanks for the advice. I have now located the bearings. They bare British made and cost £38.00 each. Since my workshop team are working on two pumps i am looking at too much money at present. I will have to buy a new pump without the grease nipple.

 

Where shall I go shopping?

 

Thanks

Just buy cheapo bearings and fit them to your existing pump along with a new seal and it will probably outlast a new pump that will have the same cheapo bearings in it anyway.

Cross reference the bearing numbers, £10-15 is a reasonable price for nos items from a decent manufacturer . . . . . 100978 is the OE number I think.

Thanks .

 

Please point me to a supplier.

Hi Richard,

 

if I knew a supplier off hand I'd have pointed you ! Dave Davies, as in fuel pumps, is a possible candidate ? He's a bearing specialist.

 

Whenever I need something like bearings I google the number, find one or another source of cross referencing the number/s (often both obsolete and current number/s) between manufacturers, Timken SKF RHP etc, then google the various numbers until I find a result on ebay or wherever. It takes time and effort, but the result is usually bearings at no more than 30% the cost of current stock from major suppliers.

 

Cheers

I'd just take the old bearings to a bearing supplier (see Yellow Pages). I've done this for various power tools and machinery, and saved a bomb compared to the price of OE spares.
