HomeHOW 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 …

Cam gear and spacer fabrication questions
Arthropraxis Sat Oct 09, 2010 2:29 pm
My cam gear is out and the template made to machine it. My question is how hard is the steel? Can I do this with a hole cutting bit, die grinder and drill bit or should I just take it to a machinist?
I need to make some cross member spacers. The manual suggests 6061 aluminum. How hard is that to DIY? It shows them made as large washers. Is there a problem with making them a rectangle?
Thanks, for any info.

Make the X-member spacers from bar and regular HS steel bit will do, It's not critical.
The 944 cam gear I CNC'd and used a Carbide end mill with a fast speed-low feed rate and cutting coolant. As for hardness I took a file to the cam gear and the gear splines are hardened but the middle section is not so you are in luck. Knock it out. You can make it easier if you have a center finder and a V-block to scribe the PCD holes and then drill a tad over 8mm bit (I used a 9mm bit)

Thanks, I didn't want to be burning up bits and getting nowhere.

And if you efitup there's always the TPC VSS kit. I have one myself for spare and it comes with the cut-outs for the CV boot flanges between the bolts

I would just order the kit but I burned up $30 in bits to get the gear out. The bolt that holds it in must be forged. So at this point it is just on principle.
