Hi all,
I had a knocking noise at idle that sounded similar to the normal diesel knock of the engine but was secondary to this. I isolated the sound to inside the manual gearbox bellhousing. So I removed the gearbox to have a look.
After removing the Dual Mass Flywheel from my 1995 3.0L Diesel Surf I found flywheel has some play in it and there is something rattling around inside! The inside of the bell housing is coated in grease that has obviously been spun out from inside the Dual Mass Flywheel
I now seem to have a choice.
1.) Replace the flywheel with a similar unit for £480+vat, plus a new 3 piece clutch (original past it's useful life), and rear engine oil seal (insurance) .
2.) Go for the 4Runner soild flywheel conversion, with a flywheel cost of £230+vat and slightly cheaper clutch.
I have read that with the solid flywheel conversion the gearbox can make more noise at idle and clutch take up is sometimes harsher. Apparently the solid flywheel is heavier so may soak up power and hinder acceleration. Also, because the solid flywheel is thinner the thrust bearing thow out may be affected. Having said this the UK Toyota 4Runner has the soild flywheel so why do I need the Dual Mass unit?
Has anyone experience of changing thier DMF and opinions on the best options? Any other relevant information and help will be gladly received.
