Hey Norm,
Mate no worries at all - I can manage without it, just have to remember where I end up scalping the property on undulating spots. So look see how you go but if you don't manage to get it done its no issue - the sun will still come up for me, no harm done at all. I know your services are in demand. :-)
Well I got the wheel off the H660. I either got lucky or your ones were lot tricker - only took one wheel off (on the problematic side) just undid the nut from the wheel side, placed a lift under the axle and a few taps of a rubber hammer got it to come away from the shaft/axle.
How would one proceed from here to replace the seal - assuming one was going to do so - don't tell me you have to hammer the shaft/axle out? If so I'll likely pass on it - but if it's not overly hard and the seal and be gotten out somehow I'm open minded to it.
I took the wheel off to try a big of a bodge effort - in reading up about similar issues one things folks advocate is using some brake fluid on the seals (whick they apply from INSIDE the gearbox) as they say this makes the rubber in the seals swell slightly and often fixes the leak.
The issue with that route being that brake fluid in your gearbox isn't a good thing.
So I thought I'd just use a syringe to with the axle angled upright (25-30 degrees I guess) I put a small amount of brake fluid in the seal area to hopefully permeate down onto the rubber part of it.
Unsure if it will do any good but figured it could not harm, which I wasn't sure about if one had put inside the gearbox (thought I suppose you could perform a flush to get rid of it but still). Also have the Penrite 00 grease, which I conceed isn't a perfect solution but I thought I would supplement the 85W-140 in it with a bit of the grease and monitor the leaks between usage. Imperfect product I know but it's an imperfect problem so I figure it's going to be better than the gearbox running low on fluid, whereas the grease will remain and is meant to be a good product thats not entirely unsuitable.
Will play by ear.
