Diff pinion oil seal
Posted: Sat Aug 06, 2016 10:57 am
I'm trying to pluck up the enthusiasm to replace the pinion oil seal in the nose of the rear axle. It's been leaking more or less since I finished the rebuild, but I left it as I hoped it might seal itself up once the car was in use again. Faint but useless hope! I think it's getting worse I just want to confirm how I think it goes before biting the bullet and crawling underneath. So...
1. undo the rear of the prop shaft and swing out of the way
2. Remove flange by undoing the retaining nut, remembering to mark it's position so that it can be tightened back to the same tension. Is this nut captive or peened over in some way?
3. Hook out the deflector dust seal and the seal itself. This sounds easy enough, but I suspect it isn't. Any tips as to the best way to do this?
4. Re-assemble in reverse order with new seal.
It's not going to be this easy I'm sure, I've worked on Lotus' for too long to believe that. What problems am I likely to encounter. Eg. How difficult is it to remove the flange once the nut is off? Is there a danger of pulling the pinion out of engagement? If so, what to do about it? Is there any need to replace anything else, eg the collapsible spacer, or the bearing, or can I get away with just the dust and oil seal?
The more I'm talking about it the more my enthusiasm for the task is dwindling away. Any helpful hints and tips very gratefully received, ...and a dollop of enthusiasm wouldn't go amiss!
