Wrench for the RV8 distributor clamp nut
John Dutton (Woodcote Green 1664) from Kent found it impossible to undo the distributor clamp nut with an ordinary spanner and eventually found a special wrench. (Apr 05)

Since having my low mileage RV8 rechipped at RPI, I have wanted to retime the car properly. As many RV8 enthusiasts will have found, I had difficulty getting a spanner on to the distributor clamp bolt. My bolt simply would not shift with a conventional spanner as there is not room to get any leverage. This maintenance task requires a special Rover service too but the good news is there are substiutes available at a fraction of the cost. Well with help from Oz I have finally managed to track down the special tool which I couldn't find it in the UK. It is a special shaped long reach angled distributor clamp nut wrench which makes the job much easier. Once I had the useful angled distributor clamp bolt wrench, I was able to move the clamp bolt and reset the timing.

The wrench has two L shaped ring spanners, with 3/8" square ends that join together with a connector, or you can use a 3/8" ratchet on either angled spanner. The 9/16" ring fits the V8. It is also much easier to get the spanner onto the bolt, which is all but invisible and pretty inaccessible.

Where can I get a long reach angled RV8 distributor clamp nut wrench?

Performance Tool & Supply
62 Main Street
PA 16701
Telephone (001) 814 362 3221

It is part number W1189 Offset Distributor Wrench W1189 and costs $22 (about £12) delivered to the UK.

I found you can get the wrench from suppliers in both the US and Australia and eventually got mine on eBay from a supplier in the US called Performance Tool & Supply. I have also seen the same part on other US websites as KD tool number 104.
