I remember a long time ago my brother telling me of a customer who came into the auto parts store he had just started at. Customer asks for set of pistons for an older jag, computer says yes, price $40 each. Storeman looks at part number, says just a minute and looks up piston for  Holden something, the dominant vehicle of the day. Same part number, price $20 each...

this is why parts  boxes started to show just a number, and even the "Fits Make, make, make etc" was quicly phased out, it enables the manufacturer to sell the same part at a range of higher prices based on the percieved wealth of the customer. If he can afford to buy an XXXXX he will expect the parts to be more expensive. I used to buy Saab disc pads at the Ford price because the car parts shop next to our second hand selling service was a good guy, and knew the con! I did the same in reverse in our shop, but I had to do it on the fly!

pycoed:
Some years ago, I had a Ssanyongg Korando & lost 5th gear. Usually a circlip comes off & 5th floats free, except the circlip is somewhere in the box! There was a chap on the owners forum who was a gearbox specialist, so I took out the transfer box & gearbox & took the gearbox to him in Presteigne. We sat on his terrace in the sun & he rebuilt the cluster for me using bits from the Ford Mustang Driver’s Club.
The gearbox (Tremec T5 wrc IIRC) was used in the “real” Mustang, with different first & second gears. He had a range of spares on the shelf all bought very cheaply through the Mustang club. Same gearbox was also used in the Sierra Cosworth 4X4.

Following this I kept tabs on Ebay for interest (as you do) & saw s/h Korando/Musso gearboxes for around £200-250 whereas the Cosworth boxes went for £750 upwards!! Sometimes a little knowledge can be a very useful thing eh?

I have another one! When I was doing classic cars, we bought an early Aston Martinn DBS  V8 rather cheap because its Chrysler Torqflite auto box was dodgy, after some investigation it turns out that exactly the same transmission also fits a Matbro Fork lift truck and there is an auto transmission specialist less than 30 miles away who carries the rebuild kit on the shelf! £90.00 . Box out and stripped, flushed out the cooked fluid, and bits of brake band, and rebuilt! Purrfect!

The fuel gauge stopped working the other day. Had been fine, then zilch, no deflection at all with a full tank.

Now diagnosis should be pretty simple if access was better. It can only be the gauge itself, a fuse, wiring or the sensor in the tank. Not a fuse as other things on the same feed are working. Access to the gauge is a right pain as it means removing the side console instrument cluster - took two days last time.

So how about the sensor in the tank? On my last 3CX the only way to get at it was to remove the tank, but on this somewhat later model I spotted a trim moulding on the off side cab edge that might just let me get at it.

Sure enough only held on by some M6 bolts and removing it revealed an amazing build up of muck - anyone would think it's been used shifting loads of earth! Digging though the buildup with a scraper, and workshop vacuum cleaner eventually revealed the flange holding the sensor in the tank and it's two pin electrical connector. Carefully puling it apart and squirting it with contact fluid made not a jot of difference. Now these sensors, as far as I can tell, vary from about 24 ohms to 75 ohms empty to full.

I stuffed a 56 ohm resistor into the loom cable socket and lo and behold we have a 2/3rds full indication on the gauge - the fault IS te sensor - no having to dig into the side console again.

When I can get through to the parts place to confirm the part number I'll order one up, but so fr they're always on the phone  :bang:
