it_cud Posted March 1, 2009 Share Posted March 1, 2009 Hi, Just fitted 1.7 TD Isuzu into my Westfield. Bolted straight onto original Manta box. Using std. Manta 1.8s friction plate with Isuzu pressure plate. Std. Manta release bearing also used. After about a week, release bearing doesn't sound good while clutch is fully depressed. Anybody done this conversion before, doubt it , but if so, what setup did you use ? Cheers, Mike. Quote Link to comment Share on other sites More sharing options...

maher the hermit Posted March 2, 2009 Share Posted March 2, 2009 i fitted a vauxhall diesel 1.7 dti in my manta and fitted it to the standard 1.8 gearbox with no problems with the clutch but i used all of the 1.8 parts (flywheel, clutch and release bearing), did you back off the clutch arm adjustment? the hex bolt with locknut on the gearbox bell houseing to give the release bearing free play because it sounds like it was in contact with the pressure plate and its knackered the bearing?

it_cud Posted March 2, 2009 Author Share Posted March 2, 2009 Hi, I set up the clearence as I thought it should be. Didn't go down the route of trying to mate Manta flywheel onto motor as Isuzu one is 'pot' type and weighs a ton. Presumably for a very good reason ? Also ring gear dias. etc come into play. My setup looked like it should work when on the bench, but after my initial test runs, maybe 30 or 40 miles ,the bearing doesn't too clever when clutch pedal is fully pressed ? Thanks, mike.

it_cud Posted March 2, 2009 Author Share Posted March 2, 2009 Hi again, Does the GM diesel bolt onto the Manta box too ? I was led to believe that only the Isuzu did ? Got me thinking about other flywheels now ! Mike. Quote Link to comment Share on other sites More sharing options...
maher the hermit Posted March 3, 2009 Share Posted March 3, 2009 yes the GM diesel bolts straight on to the 1.8 manta box its the same block as the 1.8 petrol engine, the only thing i had to do was make up engine mount plates because the engine came out of a front wheel drive astra, and change the sump+oil pickup pipe Quote Link to comment Share on other sites More sharing options...
