blkaplan Posted May 20, 2013 Report Share Posted May 20, 2013 (edited) I'd say the shop did it right, when I ran a shop, the only way to really deal with hot spots is to grind them out. you can grind anything away it just depend how long you want to have it on the grinder and how hot your willing to make the part... Its much faster and better to turn or mill the bulk of the material and then to prep the surface with a final grind if you are removing .25" IMO Edited May 20, 2013 by blkaplan Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted May 20, 2013 Author Report Share Posted May 20, 2013 To recap, not enough clearance from fully compressed T/O face to bell housing to allow Spec pp fingers to extend in a relaxed state as disc wears. Need 1/8" just to relieve fingers, another 1/8" to allow for additional wear & pp fingers rising. The flywheel is too thin in the disc seat to remove 1/8", nevermind 1/4". His thoughts are remove 1/8" off the back side - which would place the flywheel 1mm off the block. Need to check starter throw to confirm that it won't extend too far that way. And, remove some material (1/8") from the T/O spring seat to allow for the pp fingers to rest without tension. I need to confirm somehow that total pp finger height with a worn disc will still not create a pre-tensioned state. Can't be good for my crank thrust bearing to be in a constant tensioned state, on top of the slippage issue. Quote Link to comment Share on other sites More sharing options...
blkaplan Posted May 21, 2013 Report Share Posted May 21, 2013 might be time to abandon the flywheel and sell it someone else while it can still be used by someone with a normal setup? or get a clutch package that has a shorter packaging height....

I'm planning on getting the AP racing setup with a flywheel designed for it. I think selling this one as is makes more sense, since it is perfect for a stock DM setup Quote Link to comment Share on other sites More sharing options...
blkaplan Posted May 21, 2013 Report Share Posted May 21, 2013 Yep, that is the logical way forward imo. you will get it sorted eventually! Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted May 22, 2013 Author Report Share Posted May 22, 2013 Did some more playing around with the existing setup. stack height of flywheel & Spec PP = 3.125" add .15625" (offset of flywheel from back of block) = total height 3.28125" (83.343mm) PP fingers are .1875" (3/16") above PP surface unloaded - this would be with completely worn disc = 88.900mm total height PP fingers are approx .0625" (1/16") below PP surface with new disc (9mm thickness) = 82.550mm total height PP fingers are approx .0625" (1/16" )above PP surface with used disc (8.11mm thickness) = 85.725mm total height Distance from Bell housing to compressed T/O = 3.1875" (80.962mm) Distance from Bell housing to compressed (modded) T/O = 3.4062" (86.614mm) removed 1/4" from T/O seat (on slave) Part # 8636105 and 31259889. These slaves require the connector elbow with the long extension - # 30787651 Total available travel = (.374") 9.5mm, vs. (.570") 14.5mm stock removed 1/4" from T/O shoulder, shortened spring & spring cup So, this leaves .035" - only about .9mm! for additional wear (of already worn disc) before T/O is bottomed out again.

lookforjoe Posted May 29, 2013 Author Report Share Posted May 29, 2013 Still waiting for word from Precision. They said I should get a call by Friday. Started installing the RS oil cooler. First step was to fit the modified water return pipe. I added a 4AN fitting for the Tial WG water jacket Main water feed to oil cooler has to be bent as well - more pics tomorrow. Howe radiator came back - they made a complete new one instead of repairing the previous New one has expansion joints they said should resolve the stress problem. 2 Quote Link to comment Share on other sites More sharing options...

andyb5 Posted May 30, 2013 Report Share Posted May 30, 2013 Radiator looks good! Did they correct the fitment issues you had last time as well, or will this one require modifications as well? Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted May 30, 2013 Author Report Share Posted May 30, 2013 Radiator looks good! Did they correct the fitment issues you had last time as well, or will this one require modifications as well? They built it off the last one - which had the modifications (narrower tabs, splash pan hook, etc) that were needed. The fan shroud has to be modded, since the core is much deeper, but I've already done that. They don't drill & tap the mount tabs, you have to do that.

lookforjoe Posted May 30, 2013 Author Report Share Posted May 30, 2013 Volvo / EU Focus RS Oil cooler (31201911) installed. Used Volvo hoses 30774485 for the feeder, with 1/4" cut off tube side Used Volvo hose 30751747 for the return, with the top of the "C" shape cut off to turn it into an "L" Feed tube was bent over (judicious use of pry bar between block webbing and tube, and long 3/8" extension shoved up the tube for leverage) to the left (drivers side) and rotated to position the tube orifice in similar orientation to new return pipe, and to ensure clearance of driveshaft & BG when installed. Stock setup - i'm not sure the BG is going to clear the left hose.... 1 Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted June 4, 2013 Author Report Share Posted June 4, 2013 AP Clutch and KU flywheel combo arrived today. Rated for 440NM + SM style billet flywheel & DM style billet flywheel comparsion fingers sit higher, but presumably will pull in tighter once PP is loaded Precision finally called today, they said the cartridge has signs of getting very hot - I'm thinking thats 'cos the bearing let loose. They said I should check the oil feed banjo - but I know there's no restriction there, and the line is 4AN from the banjo to the turbo 1/8" NPT port. They will call me back tomorrow with pricing for the repair. They said a new cartridge is $1400. I reiterated that the turbo is only just over a year old, and only has 10k miles. We'll see what they come back with. Quote Link to comment Share on other sites More sharing options...
