Apparently there's a little more vibration, and a bit of chatter from the gearbox at idle. OTOH a colleague had his 306 HDI converted and said it was no worse, but then again, his DMF may have been on the way out. Whatever, if it was mine, I'd replace the DMF, either with a solid or a new OE DMF. It's too much of a pain dropping gearboxes :-) Regarding the clutch life, it varies according to how it's been driven, but I'd expect about 80k as a reasonable yardstick.

It's too much of a pain dropping gearboxes :-) I have come to the conclusion that on many vehicles it can be quicker and easier to lift the engine rather than remove the gearbox (I don't know about the OP model) or in many cases just slide the engine to one side while changing the clutch (I changed a fiesta 1.25 clutch like that the other day, total job less than two hours and preferable to messing about with drive shafts, suspension, gear linkages etc. |
