HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

You ground off the 3 areas on the TOB base? If you have the D951004 casting TOB, then you are good there. It may be that your SBC/LT Flywheel is very tall and sets the clutch disc splines out to far. Just clean off about 1/8" (looks like 1/8" has been taken care of LOL)

When all bolted up and the bottom BH cover is removed, the plastic base on the TOB should be at least 1/16"-1/8" away from the base of the TOB alloy casting. If not, there is pre-load on the PP tines and can cause engagement issues.

The SBC/LT1 flywheels are taller than the LS flywheels and what you just posted should be noted/wiki'ed/twittered/whatever as not to many people are doing them. I do like LT1.

What pressure plate is that and what is it's finger height from FW face. And to confirm, you are running a 153T FW?

Which part should be ground down, the clutch plate spline or the face of the TOB shaft?

I also have a LT1. I have no complaints... The car flys... Just watch that tach! I spun a bearing by over reving mine (100,000+km though). I just picked up a 383 beast of a motor to replace it. Should be fun if everything holds together Very Happy

Well we trimmed the shaft on the the TOB and cleaned the clutch collar up with about 1mm of space between the two that has taken care of the noise.
