BRM Posted January 3, 2017 Share Posted January 3, 2017 Does anyone have the sizes for the trans to engine bolts? Also the starter bolts. Quote Link to comment Share on other sites More sharing options...
DaveT Posted January 3, 2017 Share Posted January 3, 2017 From memory.... pretty sure they are 14mm hex heads. 10mm diameter. 1.25mm pitch. Lower nut on the starter was 17mm hex iirc. Other nuts were washer face or used with washers and split locks. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 4, 2017 Share Posted January 4, 2017 (edited) They're as he said 14 mm head M10x1.25 pitch thread. I think the lower starter nut should be 14mm and same thread as well. To some extent the head size can vary. You can get the correct size fastener thread of M10x1.25 pitch but have different head sizes - 14mm is oem or aftermarket bolts are commonly a little larger head size than the OEM. But I prefer Subaru fasteners for their grade and maintaining consistency if possible. Often non OEM bolts are an off size like 13mm or 15mm, sizes found nowhere else on the vehicle. That's what I mean by consistency. I just removed a bolt from a 2006 yesterday. Nominally it's a 12mm bolt M8x1.25, but it had been previously replaced and was still an M8 thread but the 12mm socket was too small. That's common with replacement non OEM bolts. The lower studs and nuts are the same thread as well. Edited January 4, 2017 by grossgary Quote Link to comment Share on other sites More sharing options...
DaveT Posted January 4, 2017 Share Posted January 4, 2017 yes, that characteristic of typical replacement bolts annoys me also. It's the different convention used between Japan made metric and Europe made metric. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 4, 2017 Share Posted January 4, 2017 ahhh so there's a reason for that! Quote Link to comment Share on other sites More sharing options...
