I'm pretty good at sourcing obscure parts, I can have a look. But what is a flex plate? Do you have a part no. you are trying to find?
A Flex Plate sits on the Converter that sits where a Flywheel should be on a Manual Gearbox. Instead of being on the engine it is in the front when the Bell housing is separated.
It has a ringear on it, so that the starter motor can turn the engine over.
Sadly I can't get a part number as Fiat are not giving it. They want £700 for a flimsy piece of plate with a gear on it. Most Breakers I've called haven't got a clue! Then others wont break the gearbox.
It's been hard trying to source one for 3 years. When the gear fails she'll go to the scrap yard after I've sold off everything I can on it, like 4 brand new tyres etc.
Pity. She could go for another 5 years with the ringear.
Cheap to run. Only £700/year compared to my 2020 Ford Focus currently at £2500/year to run. The 2018 change to Euro 6 Standard has killed the combustion market for spare parts. I.E. A simple £1 manufacturing cost for a Thermostat for the Ford Focus has been encased in a plastic multipipe enclosure. Price from Ford £118. Only in the last few months have the spares market got hold of it and so I paid £84. The fitting etc came to £354. Yes just for a £1 Thermostat. Mad!
The Thermostat is always the important thing to change first before messing with any DPF's by the way.
Reason: The early driving with a thermostat that isn't functioning properly will upset the ECU and make incorrect assumptions as when to do a burn. I only know this because of many years of tinkering with cars and racing then like a complete and utter lunatic. I regret all my bad driving but it did give me knowledge.
I can only thank Jehovah my God for all this knowledge but it's useless in this life. I'm waiting for the next to use it fully.
