And stay in front of a certain Honda! I've been on the quaife web site and they sell two atb duffs for my 020 gear box, one for a 109mm crown wheel amd one for a 111mm crown wheel. My question to you good folks is............ How do I find out which one i need? How do I measure my crown wheel? Much thanks and happy new year! #Post#: 652-------------------------------------------------- Re: Lets talk diffs By: GEL Date: January 1, 2013, 4:33 am --------------------------------------------------------- Can you tell from the gearbox code ? (the Quaife site is offline just now for me to check) Looking at the vagcat data below I would assume that the larger CW is for the higher output unit ? differential / 1.6-2.0ltr. for manual gearbox / differential / 40-102KW 1.6-2.0ltr. pinion gear set / for 4-speed manual gearbox / for 5 speed manual transmiss. 40-102KW / 3R,4R,ATH, 2Y,4S,4T, AUG,AWY ................. differential / 1.8ltr. pinion gear set / for 5 speed manual transmiss. / differential / 118KW 1.8ltr. / AYC,AYN,CBA pinion gear set / for 5 speed manual transmiss. 118KW / #Post#: 654-------------------------------------------------- Re: Lets talk diffs By: mitlom Date: January 1, 2013, 1:43 pm --------------------------------------------------------- Hi Tim, Here ya go mate.... 109mm = 8v gearbox 111mm = 16v gearbox As suggested by GEL you can check which you have by checking the gearbox code which is stamped on the bottom of the bellhousing ;) #Post#: 659-------------------------------------------------- Re: Lets talk diffs By: Tim Watson Date: January 2, 2013, 12:33 pm --------------------------------------------------------- Legends, why can't everyone explain stuff that simply!
