The most commonly discussed Achilles heel to the Fiesta XR4/ST150 is the IB5 transmission. The gearbox doesn’t randomly explode, but has one significant weakness in addition to the “usual” front-wheel-drive hot-hatch gearbox fragility.
Ignore the differential failures caused by one-wheel burnout antics the real problem is the factory fitted differential bearings. The only solution is to replace these bearings with a metal caged alternative.
I wanted to see if there were cheaper options so I started with the two Ford Part Numbers and did some Googling. The IB5 differential is supported by two different sized bearings of 65mm and 71mm outside diameter.
The 65mm Bearing: – Ford Part Numbers: 1677043, 1063385 or 5092541 These cross reference to aftermarket codes: – LM29749/LM29711 – R38Z-24
The 71mm Bearing: – Ford Part Number: 1070470 This bearing cross references to: – NP618892/NP355857 – BT1-0017 – 329149
Sourcing for Less $$ With the part numbers in hand I tried the usual local bearing suppliers and found that it wasn’t easy to get a local (within Australia) source that carried both bearings at a good price. It was back to Google and that brought me to Henderson Bearings in the UK.
Henderson Bearings have an easy to use website that lists the two bearings needed at great pricing. Add in the Royal Mail or UPS delivery options and it’s possible to have a set of differential bearings delivered to your door from about AUD80 (Royal Mail)!
In 1998 Kyosho released the PureTen GP Spider Mk2, a nitro powered 1/10th scale touring car featuring an in-house developed GS11R engine. On this page you will find a collection of resources that will help you restore and maintain these unique cars. Continue reading Kyosho PureTen GP Spider Mk2 – Resources
The Quanum Trifecta sold through Hobbyking is a circa 295mm Tri-copter that folds for transport yet still carries 8″ propellers. In my first post I gave a bit of background on the project and following on from that this post will give a rundown of the parts sourced for the build.
The hardest thing about building my own quadcopter from random parts has been the process I’m about to describe. Using (flying) it. You see, if like me you’ve never flown anything before you’re going to be starting at the bottom of a steep learning curve. Continue reading Lessons from Flying my DIY Quadcopter Badly
It has taken a few weeks to get myself to the point of assembling my drone, but finally I’m now largely assembled, wired and starting back on the “do it right” bits like using Loctite to secure some of the frame screws. Continue reading See how I’m Assembling my Drone
