Re: [VintageLambo] Second Gear

Jack, You"ve opened a new question with you comment The fact that you are at full length on the adjustment is usually indicative of a pretty worn clutch disk. I don"t believe I have a wear problem with the clutch According to the previous owner When the engine was rebuilt, there was a problem getting the clutch to engage fully, so they decided this was due to the flywheel being worn and needed to be replaced. A brand new flywheel was purchased (Australian $2100) along with a refurbished pressure plate (2000 miles ago). I have the original flywheel and it doesn"t appear to be scored etc so I"m not sure that there was major wear on it. What are your thoughts on an incorrect slave cylinder having been used and if I end up putting spacers between the slave mounting bracket and the bell housing, (which I should be able to do without disconnecting the hydraulic lines or removal of any components) what would be the impact on clutch operation - would it open far enough ? As for changed operation of the gear box after the adjustment - the box does feel lighter between ALL gears, I tried a straight shift from 3rd to 2nd (where I have trouble) with minimal effort at rev matching etc and had a minor "clash", much less than prior to the adjustment, syncro does work from 1st to reverse and back again - never tried it before so I don"t know if it is an improvement in this area. General Comment - much improved gear box performance following the adjustment to the slave push rod free play :-) :-) Thanks for the help John As An Aside Current temperature around 34 degrees C with our airconditioners running - just in case you you snow bound Northern Hemisphere persons would like to know what its like DOWNUNDER :-)) jallott@albury.net.au ----- Original Message ----- From: Jack Riddell To: VintageLambo@yahoogroups.com Sent: Tuesday, December 31, 2002 10:46 AM Subject: Re: [VintageLambo] Second Gear Hi John, The fact that you are at full length on the adjustment is usually indicative of a pretty worn clutch disk. Even so, having that small bit of pedal travel will help your shifting and it will help reduce further wear. With no pedal travel, you are in a condition where the throwout bearing is making contact with the fingers of the pressure plate, and in extreme cases, you may actually cause some clutch engagement and this will often cause clutch slippage under acceleration - not a good thing and can lead to expensive clutch work. I didn"t mention the hardware sizes because I have found that there are differences from car to car. On my car, both the push rod hex and the lock nut are 14mm. Sometimes, I think the factory just used what was handy at the moment. I think it is safe to say if you go under the car with a pair of 14"s and a 13, you will be OK. Let us know how the run goes. Happy New Year, Jack John Allott wrote: Jack, I have just adjusted the clutch slave free-play. A couple of points - The push rod from the slave has a 14mm hex for adjusting, the lock nut is 13mm - might save some time if anybody else gets under their car There was NO play in the slave on my car - now adjusted to around 1mm of freeplay. This puts the adjustment at its limit and to get any more adjustment, I would need to insert a couple of spacers between the slave body and the mounts to the bell housing - maybe something for people to consider when rebuilding a clutch. I haven"t taken the car for a run yet so I will report if it was worth the effort later:-) John jallott@albury.net.au ----- Original Message ----- From: Jack Riddell To: VintageLambo@yahoogroups.com Sent: Friday, December 27, 2002 12:28 PM Subject: Re: [VintageLambo] Second Gear Hi John, The item about the clutch adjustment is that you need to have a small amount of clutch pedal movement before the throwout bearing meets the clutch fingers. This ensures proper engagement and can have a big effect on shifting performance.
