Clutch wear

[--weezl--]

ok, got a phone call from the dealership my truck is getting fixed at, lots of arguing, but essentially, it's kind of under warranty... right now it's going to the parts manager for approval of warranty, the issue is inner clutch wear, and a few small hot spots on the fly wheel, what i need to know is what causes for these problems, are there? especially things that could cause both of these issues...

i do NOT ride my clutch, which is the only reason they gave me for the 2 issues...

is it possible that inner clutch wear is caused by a manufacture problem or a cheap clutch, or something that's not designed for the power that's being put through it... any possible reasons that could cause it, i've got the service adviser recorded saying "we have no evidence that you ride your clutch, but typically that's what caused it" which essentially means if i can put doubt into the fact that this wear, and hot spot issue can be caused by something other than abuse, i can get them to pay for it...

they are supposed to be calling me tomorrow morning

also, how can that cause the transmission to not go into 1st gear? the only way i see those problems all present, is if the slave isn't working fully, and leaving the clutch partially engaged, which would cause the clutch to still be grabbing(slightly) when i have the pedal pushed down all the way and cause the flywheel to heat up beyond where it should... right?

post number 2 sounds like a slave to me.

Dealerships always try to basically blame the driver even if it was part failure. they want you to pay for everything so they lose no money.

 

[--weezl--]

would it be fair to say, and i want anyone's opinion on this...

that the only way that inner clutch wear, a few hot spots, which is most likely caused by partial engagement of the clutch, AND the inability to get into 1st gear from a dead stop, until the syncros sync everything up, and the truck rolling forward, while trying to get into 1st gear in 4 low, is caused by a slave cylinder, or master cylinder issue?

anyone have ANY thoughts on this point?

i should clarify, all of the symptoms/physical problems:

-inner wear on clutch, consistent with riding the clutch, or partial engagement of the clutch for a prolonged period of time
-roughly 5 small quarter sized hot spots on the flywheel, consistent with riding the clutch, or partial engagement of the clutch for a prolonged period of time
-inability/difficulty getting into 1st gear, from a stop, when the transmission was in neutral with the clutch out, motor hot
-when attempting to get into 1st gear, in 4L clutch in, the truck rolls forward slightly
-no difficulty getting into gear when the problem is persistant, but engine is not running

It's not disengaging all the way, they screwed up the clutch job or the slave/master isn't working correctly, air in the line...

air in the line does not seem like a possible, as the transmission has been out since the clutch was put in, and i would imagine that you would need to bleed the clutch once it's put back in... though it would totally cause a similar problem if that were the case... (transmission was out for this problem)

thanks for the posts both of you guys! it's going to give me some more ammo when i talk to the dealership last night...

If you unbolt the slave, you introduce air in the system and it needs to be bled. If only one tech was working on it, he may have only gravity bled it, which doesn't work that great. You don't have to do that every time you take the tranny out.

hmm, still a problem with the install imo... air has to get in there some how... the problem started before the system was opened up, so either air was in the system somewhere, and popped into somewhere that made it cause this problem, or it is a malfunctioning slave, either way, it was the labour, or the parts that were put in, 1 year ago, this week, that caused my clutch to get worn out improperly

 

[pcollins]

air in the system isn't going to cause the clutch to ride and be partially disengaged constantly, it only affects the shifts.

 

[--weezl--]

no i understand that, i mean if it 's not fully disengaging, so say, if i'm stopped at a stop light, it's still grabbing a little, clutch pushed in, the clutch is still grabbing the flywheel slightly, causing wear, and heat

 

[--weezl--]

ok, the slave cylinder is not getting replaced, the service adviser just talked to me on the phone, says the clutch manufacture saw the clutch, and said that the clutch is binding up and causing it to grab the flywheel when it should have been slipping fully... does this sound right? if that is the case, it WOULD cause this problem, i'm just curious as to how likely of a situation that is...

i've got the last 2 phone calls recorded, including this one, where i express my concern that the slave is messed up, so if it malfunctions again, i can always take it back saying i said it was the slave, and you decided not to fix it... i'm going to take it for a long drive before i sign anything, and make sure it's not still doing it



also, when you pull a transmission at the dealership, will they automatically replace the fluid?
