L 5 Speed behind EA81 200mm clutch :(

Maybe some pics later, but as i started to suspect, the Holden Isuzu Gemini friction plate mixed with Subes 4WD 200mm pressure plate and the 5 speed clutch fork and throwout bearing combo has its drawbacks when converting an MY EA81 from its four speed 4WD to an L 5 speed 4WD.

All has to do with where the clutch throw out bearing levers against the clutch pressure plate fingers and how much adjustment and pedal throw you get.

I also retaINED THE caps lock off MY clutch pedal ...

The difference between the pressure plates is the size of the hole that is between the finger tips, an L bearing pushes further along, almost to a first knuckle if they were real fingers, rather than right at the tip.

About to resolve all the non issues that I have had in 9 years 150,000km with the 5 speed in it. Should just be a more refined shifter, cable adjust when the EA82M is in and running.

Why not just have your flywheel machined down to a 20.7mm step and fit the EA82 clutch pressure plate then call it a day?

That setup has been tried and tested many times with good results - saves stuffing around with a mixed bags of parts.

At the time of conversion the clutch was fairly new, the machining down of a flywheel was not mentioned in any posts back in 2005 and might just go down that path soon if things not work out with this EA82 fitment

Fair enough. While it may not have been on here I'm sure it would have been a known thing on the USMB - even though I had little to do with that forum back then.

Best of luck with it

Cheers

When you say L.Series, are you referring to 2WD or 4WD model 5 speed gearbox? From memory only the EA82 2WD 5 Speeds had the 200mm clutch. All 4WD used the 225mm setup.

I would only use the 225mm kit if you're planning to do any towing or 4WDing.

The EA81 came with both 200mm and 225mm clutches depending on their year of manufacture.

L 5MT DR 3.7:1 diff ratio. Tell you what, for this clutch has been in use for 240,000km , with the Gemini friction plate having done about 180,000 of that - everything is in pretty good condition.Friction plate lining looks almost new, just some cracks look like apearing in the centre spindle plate section with the damper springs. May have been a bad thing one day soon....

The EA82T 2WD 5 speed with 25 spline stubs used the 4WD 225mm clutch and flywheel, non turbos got the 200mm FWD clutch, which still different to EA81 clutches - different flywheel step and size of ;hole' between clutch spring finger tips
