Jimmmy0_0 Posted July 22, 2008 Share Posted July 22, 2008 Ok the new clutch arrived to day along with parts to finish the engine install, but all came to a stop when I noticed that the new clutch is bigger than the old one, plus the spline shape is different. The engine I was told is a 1500 with the serial number FM40276HE. The o/d gearbox I want to fit has the fine type splines as in the new clutch, (for a 1500) pictured. The old gearbox had the course style splines.As you can see in the pictures the bolt holes for the new clutch are very different from the old ones + the splines are also very different. (as pictured).My questions are (wait for it) 1. Is the engine really a 1500 with serial no FM40276HE2. How do I sort out the clutch sizes and spline shapes to fit the engine and o/d box together3. Is it possible that someone fitted a 1300 flywheel to a 1500 engine (sorry if this is a stupid question as I am not sure if its possible)I have also added a picture of the car in the paint shop just after it was baked 8) Link to comment Share on other sites More sharing options...

Clive Posted July 22, 2008 Share Posted July 22, 2008 fm is 1500. The proper 1500 clutch has the fine splines and a diameter of 7 1/4". The 1300 variants had 6 1/2", GT6/vitesse/dolly 1850+sprint, TR7 all 8 1/2". What diamet is the old plate? would guess it is 6 1/2" and somebody has fitted a 1300 flywheel to the engine. You could therefore either get a late dolomite 1300 clutch (6 1/2", fine spline) to fit to the current flywheel, or get a spit/dolly 1500 flywheel and get it all as it should be, probably the wise choice.Nice paintjob BTWClive Link to comment Share on other sites More sharing options...
thealligator Posted July 22, 2008 Share Posted July 22, 2008 You probable have a 3 Rail Gearbox from 1300 Link to comment Share on other sites More sharing options...
Jimmmy0_0 Posted July 22, 2008 Author Share Posted July 22, 2008 The new o/d box is a single rail, i have just finished rebuilding it.cliftyhanger: Thanks for letting me know that its a 1500 and about the clutch types. Link to comment Share on other sites More sharing options...
Clive Posted July 23, 2008 Share Posted July 23, 2008 No worries. Sounds complicated, but it isn't. All the clutch sizes are available with fine or corse teeth!Clive Link to comment Share on other sites More sharing options...
JonB67 Posted July 23, 2008 Share Posted July 23, 2008 Wouldn't bother changing back. The 1300 flywheel is lighter, and the 6 1/2 inch clutch perfectly adequate.Jon Link to comment Share on other sites More sharing options...
nige Posted July 24, 2008 Share Posted July 24, 2008 i have the same issues, am putting a 1500 engine on 1300 gearbox, am going with some advice on here and using my 1300 flywheel and clutch, - you do have to drill out the flywheel crank bolt holes though. Am hoping the little clutch can handle the extra power.. we shall see.. Link to comment Share on other sites More sharing options...

Or if fitting an overdrive or whatever. Not a problem, except you end up ordering the wrong parts! Link to comment Share on other sites More sharing options...
Jimmmy0_0 Posted July 25, 2008 Author Share Posted July 25, 2008 I got a new flywheel today. I just fitted it with the new clutch and overhauled gearbox and it all went together fine so the engine and box will go in the car tomorrow Link to comment Share on other sites More sharing options...
Clive Posted July 25, 2008 Share Posted July 25, 2008 Excellent :) Sometimes it is just easier to get the car "standard" and undo some of the moifications done by PO's. The subsequent owner in many years time will thank you too!Clive Link to comment Share on other sites More sharing options...
