g50 clutch job, lubes and thread locker???

[KCinBR]

Is it recomended to use thread locker, either red or blue, on flywheel and PP bolts.

Also would like to know about lube for trans splines and cross shaft (new type shaft)

Thanks to ALL YALL

Red on the flywheel. Nothing on the PP. Do a search on the cross shaft-much discussion on what should be used.

there is I think some good Wurth stuff for the shaft and splines... I didn't use it and should have looked into it more at the time - there are threads out there with info.

Not necessary to use red Loctite 274 on the flywheel screws. And you can reuse them if the triple square/XZN heads are still tight & clean.

The factory appeared to use a copper antiseize on the input shaft splines. I believe the Porsche spec'd type of lube is Optimoly HT

The long debated cross shaft lubricant for the factory style, goofy little needle casing bearings is called Olista Longtime 3 EP. It's made by Castrol.

Here's the factory tech bulletin that specs what grease to use. G50 Cross-shaft Update

I found some information which also states Mobil Mobilux 3 is an alternative to Olista Longtime 3.

I stumbled across another product called Dow Corning 1292 Long Life Bearing Grease that seems to work pretty well too. I found this by doing some research for an alternative to the Olista product, which I found hard to find back in 2000. I've since experimented with some other grease to see how it stacks up to the Dow 1292. Last spring I put some Mobil XHP220 industrial grease in one of the cross shaft bearings to see how it fares. I'll be taking the engine out soon and I can see how it held up to about 4000 miles of use with a high effort clutch and track abuse.

Bosch grease is also said to be a good use for these shaft bearings. I think this grease is also what the steering rack on our cars is originally equipped. That stuff lasts a long time. But once it goes, it's gone and dry. I relubed my rack with an off the shelf wheel bearing grease and I suspect that was a mistake because steering effort has been high ever since.
