Jensen Healey Specific Manual Eccentric Hub.

AUD$125.00 + 40.00 Express Shipping for 4 - 6 Business days (tracked) ~ USD$125-135 including shipping depending on exchange rate and paypal fees as of 24 Jan 2017

Ditch the 2x 6005's, the tensioner shell and sloppy adjustment nut and allow replacement with the superior 1 piece Timing Belt Bearing SKF 414871A or the Flennor FS03299.

Either will fit this hub made especially for the Jensen Healey.

4140 Alloy Steel
Full concentric abutment with spot face on the block increasing rigidity.
Full concentric abutment with spot face on the block reducing carving of block spot face upon multiple readjustments.
Centralized Adjustment nut allowing normal spanners.
Protruding hex to allow for easier spanner fit.
Hard shoulder while pressing in to avoid misalignment.
Easier to adjust tension.
Wider Roller over the Stock J-H Shell.
Reduced radial offset yet increased OD of roller to allow for less sensitive adjustment.
24mm adjustment hex
Parts supplied: Tensioner Hub, High Tensile Nyloc and washer.
Bearing not included.

We have done a small batch of these. Please let me know if you are interested.

Did a minor update today to make sure the Nyloc is fully engaged on the stud. Please check when installing that you have some exposed thread when you torque the nyloc to specification. All Hubs now have this High Tensile Nyloc and Washer included.

You guys should all buy two. One as a worthwhile upgrade for your 907 engine, and one as a piece of sculpture for your desk.

This is a good upgrade over the OEM J-H tensioner assembly. Good stuff.

There are junk bearing brands out there in the world, but IMHO, you can't go wrong with SKF. They're a top drawer bearing manufacturer.

Flennor makes timing belts (like Gates, Goodyear, Dayco, etc). The tensioner bearing Flennor markets has recently become popular in the Lotus world, and JAE sells it... although they'll also sell you an SKF if you specifically request it.

Or you can get one of many comparable brands at a local bearing supply. Just drop the SKF part number, and they can cross-reference it. But by 'quality', don't buy cheap.

There's a visual clone of this bearing that has blue seals. It's one of those 'junk' bearings mentioned above, and every example I've seen has been bad out of the box. It's made in China. I don't recall the brand name, but it's something silly like "Blue Bird"... or blue-something. With blue seals. Stay safe, don't buy a bearing with blue seals. I know that excludes other good bearings that happen to have blue seals, but it will also keep you from this bad one.

Tim Engel

Off topic but...
Early Lotus Esprits used a Citroen transaxle. A special tool is required to remove the large nut at the back of the secondary shaft, and I made one years ago. It's not pretty, but it works. A Citroen specialist in the Neatherlands, Harry Martens, developed an improved tool that's a 'real piece of work' just by design. Plus, it's beautifully machined out of stainless, then buffed to a shine. He asks US$250 for a glorified socket. I didn't need one, since my old hack still works. But I bought one just because it's such a fine piece of metal sculpture. Sometimes want exceeds need.

Regards,
Tim Engel

Reply FYI>>>> about timing belts: there are numerous tooth patterns that look similar but are different, lotus used belt part number A907E0191ZE. i only buy belts directly from QED.
They cost more but you know they're for the 907 cam pulleys.

The 907's original trapezoidal tooth belt is a 3/8" pitch Imperial belt (otherwise known as Profile Size "L"), and many companies sell that size. The only caveat is that you want 133 teeth and 1 inch wide.

Other trapezoidal belts may have the same tooth shape, but they're all in incrementally different sizes (pitches). They won't match the pulley teeth and lay naturally against the pulley. You know right away if it's right or wrong. The round-tooth belts are more tricky. There are 3/8" pitch belts in HTD, GT1, and GT2 round tooth forms, and they look deceptively alike. But they're not the same, and the GT belts do NOT ride properly on the HTD pulleys.

Gates Rubber makes more timing belts than any other brand in the world, and contract manufactures belts for many of the other big names you might think of as their competitors. For the trapezoidal tooth belt, just remember one part number... and depending upon where you live, it's...
Gates T104 in the US, Canada, Australia, etc.
Gates 5146 in the UK

Walk into any good auto parts store/ motor factors, give them the Gates part number for the country you're in, and they can cross-ref to whatever brand they stock (everybody knows Gates). If it's a name brand you recognize, buy it. If it's a no-name, low-price special from China, don't buy it. Doing that will get you to something like...
Dayco 95104
Goodyear 40104
Flennor 41133
Nipparts J1121030

If you want the 'best', longest lasting trapezoidal belt you can get at this time, then stretch your memory a little further, and ask for a Gates Racing T104RB blue belt. Write it down and put it in the glove box. Available at RockAuto.com and NAPA in North America.

Tim Engel

Frank & Don,
Go up to the first message in this thread, and you'll see that Peter updated it with new pricing information as of Jan 24th. He wrote:

> "AUD$125.00 + 40.00 Express Shipping for 4 - 6 Business days (tracked)
> ~USD$125-135 including shipping depending on exchange rate and paypal fees as of 24 Jan 2017"

Note that, as it's used above, the ~ (tilde symbol) means "approximately". Approximately USD$125-135 including shipping.

Regards,
Tim Engel

Yes, the way I understand it, you send us an invoice via Pay Pal and then we pay using the same media..

Frank

I've ordered from the UK and although the seller prices it in UK pounds, when I pay, it is converted to US dollars and charged to me...works a treat, as the Brits say

Yes..you can go to PayPal.com and open an account..they charge to your banking checking account. Widely used and very safe...you pay no fees, the seller pays the fees...Works great...but the seller has to send us an invoice or something so we can pay him...I am assuming he uses PayPal??? Maybe he will read this....

Also when you send money to pay a bill you are invoiced for, PayPal also sends your name and mailing or shipping address which you gave them when you opened the account. Quite easy and automatic. I use it very often buying things on eBay and so on...

I meant the sellers Paypal account. I have an account and use it all the time.

Are SKF 414871A or Flennor FS03299 bearings actually available? I have been searching online, been to two auto parts stores and the Ford dealership and can't find either. Does anybody know a source? The closest I have come appears to be someone willing to provide an equivalent from China.

Thanks-
