l67ss Posted January 28, 2013 Report Posted January 28, 2013 how come every one machines the flywheel for a 3.8 instead of using a spacer btween the block and tranny jus curious Quote
carkhz316 Posted January 28, 2013 Report Posted January 28, 2013 Its probably because machining the flywheel down is cheaper and easier than trying to buy/ find a spacer to mate those two together. Quote
l67ss Posted January 28, 2013 Author Report Posted January 28, 2013 so its 4 ease of instalation not function kool thanks man Quote
19Cutlass94 Posted January 28, 2013 Report Posted January 28, 2013 The only reason to machine a flywheel is if the surface is not good enough/clean enough to use with a new disc. There's no need to use spacers of any type. Sent from my iPhone in some random spot of Texas. Quote
l67ss Posted January 28, 2013 Author Report Posted January 28, 2013 i was told the offset of a rwd 3.8 f/w different than a fwd havent checked myself just planning ahead Quote
GtpKo Posted January 28, 2013 Report Posted January 28, 2013 Are you referring to why is it common to machine the 3800 F-body flywheel down to .84" for FWD 5-speed applications? The reason for that is clutch/bearing clearance differences between the 284 and T5. In other words, to make a non-standard application fit. Otherwise, the clutch may not engage/disengage fully or you may not get it to bolt together. Quote
pshojo Posted January 28, 2013 Report Posted January 28, 2013 Just buy one complete. Here is company friends of mine has used for flywheels for 3800 to 5spd and F40. Then its done and you don't have to worry about machining. http://specclutch.com/conversion_combos/view/9 http://specclutch.com/conversions Quote
l67ss Posted January 28, 2013 Author Report Posted January 28, 2013 so y not just use a spacer on the bellhousing like on a 5.3 rwd to early tranny should correct the offset Quote
19Cutlass94 Posted January 28, 2013 Report Posted January 28, 2013 Cause you don't need it.... Sent from my iPhone in some random spot of Texas. Quote
GtpKo Posted January 29, 2013 Report Posted January 29, 2013 Milling the flywheel is simpler, easier, cheaper, and lighter. A shop might do it for say, $20? Quote
pshojo Posted January 29, 2013 Report Posted January 29, 2013 Anytime someone says "mill" I see $$. Maybe that is from being in manufacturing so long. I think I saw the flywheels were aluminum. Speaking of flywheels. Where have you all seen good places to get flywheel ? Being used to dodges, I could find aluminum flywheels easily. I'm looking for my 3,4 DOHC Quote
19Cutlass94 Posted January 30, 2013 Report Posted January 30, 2013 I think spec makes flywheels for the 5spds. OEM GM flywheels can still be had but take some time to find Sent from my iPhone in some random spot of Texas. Quote
pshojo Posted January 30, 2013 Report Posted January 30, 2013 They seem to be somewhat available but all over the spectrum of $100-300, at least on Rock Auto. But sometimes I don't know if I completely trust rock auto. Quote
19Cutlass94 Posted January 30, 2013 Report Posted January 30, 2013 Sometimes they are hit or miss. Which is why I only buy the close out deals so when it is wrong, they just refund my money. Haha Sent from my iPhone in some random spot of Texas. Quote
l67ss Posted January 31, 2013 Author Report Posted January 31, 2013 they never made a 3.8 fwd 5-speed Quote
