Ok attached is a picture of my flywheel and as can be seenit has a ridge on it (less than a 1/64 ")
question is do you think this can be machined out and still have enough meat or should I bite the bullet and get myself a aluminium one ?
OK I’ll try to respond all in one answer.
Damn you gotta love this site.
Wiggles:- that’s what I’m hoping
Peterjb:_ That’s a good idea but at the moment it is on an engine stand
Matchlesspat:_ not sure how this is relevant or is it perhaps a fetish of yours
or maybe you have some information that I can use (please)
As always thanks for all the input VERY much appreciated.
You don’t say what this is going into, but in general, absent any other drive train modifications, an aluminum flywheel will make moving from a dead stop more difficult. If this is a heavier saloon, an aluminum flywheel is not for you. Rule of thumb: Light car, light flywheel, heavy car heavy flywheel. Same for the rear axle ratio. Under 3.54, heavy flywheel, 3.73 and up, light flywheel.
FYI, When my shop disassembled my 3.8 engine from my S Type, manufactured in November '64, they found the flywheel was drilled for both the spring clutch (10 inch) and diaphragm clutch (9.5 inch). That makes it simpler for me as I plan to upgrade to the diaphragm type for ease of operation.
To me - ultimate goal would be a 10" diaphragm. But this does not come from Jag linepup AFAIK.
This would make things easier with T-5 setup (Jeep 10" clutch plate).
I used a spring type 10" pressure plate with a standard mustang 10" disc (for my T5). Works great, it’s not too heavy on the leg (as everyone said it would be) and grabs really hard and firmly.
Gary, pull those pressure plate locating pins out first if you can and save them. I drilled a smaller pilot hole straight through so I can punch them out next time. Or the shop may do it. Then the shop can just cut straight over the whole face, much easier for them.
Great thought I am going to remove them and I love your idea of drilling a hole which means I shall have to use my new drill press that I set up after owning it for 5 years :).
Um… be VERY careful, using a inexpensive drill press to drill a precise-location hole: normal twist bits and cheap drill presses do not easily do precision drilling.
