92 SHO MTX transmission engine issues/ long term maintenance

[Bryan]

Okay so my trans on my 92 MTX is acting up. Sounds like a hissing sound every time I push in on the clutch to change gears. I have been told through out here that it stems from a possible bad throw out bearing. Now I have a few questions here. First is what is the job like to get the transmission out and replace the clutch? Also I think also the input shaft bearing is also going as I can hear a chattering sound when the car is going. Mostly this is at low speed. I have an engine stand and I hear you need to support the engine. Should I have the flywheel resurfaced too? Are clutch parts for this car's transmission still available?

Next is while I have the transmission out I want to do some more maintenance on the engine itself. Such as rear main seal, possible oil pan gasket since its a mess of oil and grease. I mean its leaking somewhere. Lastly I want to try getting the rod bearings done too since I am approaching 120k miles on the car. What kind of job is that like? Can it even be done while the engine is in the car?

Josh at shonutperformance has a video that shows you how to remove and install a clutch along with some printed instructions. Here is a related thread

Need help !!!! Clutch replacement 93 MTX

so I decided to take on the challenge to replacing my clutch due to being on a budget and kinda stuck in the middle of the project, so right now all I've done so far is disconnected all front end suspension such as ball joints, sway bar links and steering rods also I've removed the starter and...

Shophoenix project website has instructions on doing rod bearings

here is the old shophoenix site stuff. Might have to start calling it the yamahasho.com site
If the oil pan is coming off you might as well do the rod bearings. Just provide a good amount of time for oil to drip out before doing bearings. You'll get much less oil on your face and eyes if the engine is still in the car.
You can pull everything or pull tra nny and leave engine in the car with the weight supported so you can lower the subframe to get the 5 speed out.

Hey thanks for the info! Gonna be gathering parts and around spring time next year gonna tear into it again. One question though. I see SHOSource has an aluminum flywheel and stage one clutch kit from clutchmasters. What is you guys opinion of this stuff?

 

[luigisho]

They spin up faster and decelerate faster. I would not waste my money on Al flywheel (again). I like the characterisitcs of the oem flywheel. That is just one person's impressions though.

So you won't waste money on an aluminum flywheel because they are unreliable or just different characteristics?

 

[luigisho]

Different characteristics. Just depends what you want the car to be and how often it gets driven. For a p iss around car you can do all kinds of stuff to it. I don't have that itch to do that to early SHOs anymore. Not worth the time and hassle. I really just try and enjoy them as they are.

If you want to unlock power you need a platform that has more to give without engine work or boosting from n/a. I wish I still had my GTP or a GenIV SHO or something already boosted that I could get a nice little bump up easily with much less $$$ & risk to the engine.

I agree with Luigisho. I have driven my 1992 SHO with both standard and aluminum flywheels. I prefer the standard flywheel. I found it smoother and requires less slipping to get car moving. Save your money.

Sounds good. I agree I just plan on not really doing any real performance, and just want the car to be what it was from the factory. I'll get the stock stuff then. So think its better to have the original flywheel resurfaced or get a new one?

 

[luigisho]

Not sure how much it's been turned but I suspect it has plenty of life left in it. I never had to replace a stock flywheel for anything other than trying out aftermarket lighter ones. Stock are pretty durable
