gadget Posted March 31, 2018 Share Posted March 31, 2018 Just spotted that i have a leaking front pinion seal so that's tomorrow's job worked out. Looked up the torque settings for the pinion bolt in the haynes manual and it's got 76Nm for the rear and 100Nm for the front. I would expect them to be the same. Out of curiosity does anyone know why they are different? Quote Link to comment Share on other sites More sharing options...
Ex Member Posted March 31, 2018 Share Posted March 31, 2018 First it would help knowing what year Discovery we are discussing.... I will assume it is one that has the rotoflex coupling on the rear and is a complete PITA. On the front, make sure you use a new nut as it is probably a nyloc.

gadget Posted March 31, 2018 Author Share Posted March 31, 2018 It's a Discovery 2. I thought that only Discovery 2 used bolts for the pinion and Discovery 1 used nuts? I did the rear about 14 years ago. Not surprisingly, It started to leak just after the LR warranty expired. You're right about that being a PITA. The prop locating pin was a right pain to dislodge.

teabag Posted March 31, 2018 Share Posted March 31, 2018 I haven't a clue and not even curios , but it's light weight compared to the D1 with a130 Nm at both diffs. Some D1s do use a M12 bolt instead of a nut to attached both the flanges, also some don't have a Rotaflex coupling fitted to the rear prop when they left the factory.

Ex Member Posted March 31, 2018 Share Posted March 31, 2018 Okay. The Discovery 2 Genuine Workshop Manual says 100 Nm for both front and rear. I would get a genuine manual. I never trust that Haynes junk. 76 Nm is mentioned for the rotoflex bolts, which may be where the confusion originates. https://l.b5z.net/i/u/6064257/f/D2_Workshop_Manual.pdf Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 1, 2018 Share Posted April 1, 2018 Same front to rear even with 3 bolt / 4 bolt flange 100 is cennter...its actiually between 90-110 N Quote Link to comment Share on other sites More sharing options...
gadget Posted April 1, 2018 Author Share Posted April 1, 2018 Replaced the pinion seal earlier and put a new flange in too because there are two distinct grooves in the original where the seal sat. I noticed the front of the transfer box is wet too, so another leak to investigate 23 hours ago, teabag said: I haven't a clue and not even curios , but it's light weight compared to the D1 with a130 Nm at both diffs. The loss of axle torque prowess in the pinion bolt is more than made up for with the 450Nm of the drive shaft stake nut 23 hours ago, Red90 said: Okay.

Probably a typo in the Haynes manual then for the pinion bolt torque. With all it's faults the Haynes is handy because it's lives in the car but the workshop manual pdf is very useful - thanks. 11 hours ago, Hybrid_From_Hell said: 100 is cennter...its actiually between 90-110 I see what you did there Quote Link to comment Share on other sites More sharing options...
