Ok - got the old seal out, just tapped around the rubber part of it a tad with a flat head screwdriver, came out pretty easily. any seal that will fit will do, not like the axle is rotating at any speed, maybe double if if you can get it in the size. Norm when you said this did you mean if the space allowed it to place two seal in rather than one? i.e one could place two 1/8" thick seals rather than a single 1/4" thick one. I only ask as it almost appears there's another seal in behind the one I removed - looking at the gearbox assembly diagram I can't see exactly what it might be - is in too far for me to remove, but a tad curious, can see a slight amount of gearbox oil leaking out under it - whatever it is. The old seal that was removed appears to definitely be the 1/4" thickness.

Norm, Grabbed the replacement seals - got two so I have a backup onhand. Would you place the seals back on 'dry' or apply a little 'red rubber grease' to assist getting them on easily & also to protect them from petroleum products etc whilst on? Cheers EDIT: Seems a tad on the backside of it is a good idea: https://www.randysworldwide.com/blogs/top-10-axle-seal-installation-tips

Hi Nick, you are going well. I figure because of the depth of the housing the seal fits in I figure there is the bearing in there and probably 3 seals behind it. They possibly figured they could use 3 seals as a good seal and bearing retainer in one. Anyway just replacing the outer seal should keep the oil in for many years. Rubber grease is good if you have some, otherwise a wipe of oil will do the job. Also a wipe of silicone around the outside of the seal helps it go in and helps seal it against leaks there

Hi Norm,
Again firstly, THANK YOU for the replies.
All done, I packed the rear of the seal with a general lithium grease, it went on over the pinion and axle easily enough - was careful to ensure I thoroughly cleaned beforehand to ensure no grit etc was accidently put in that could compronise the seal to metal contact. Was careful to not unevenly push the seal in, didn;t have a large enough socket to use an d no slide hammer - so improvised with a large round headed spanner that I slipped over the seal and gently tapped in different spots with a hammer, went in without issues - nice flush fit.
Wiped down thoroughly, replaced the wheels (didn't do the seal on the other side as it's had no issues).
Topped up the gearbox, as I had it I put about 100ml of the semi-fluid grease in first - then filled up until it overflowed with the Penrite 85W-140 mineral gear oil. Moved the gear position around during filling to ensure there were no voids etc. Wiped everything down very thoroughly to allow spotting of any leaks.
Took for brief spin, came back left for an hour, checked and no leaks at all. Seems a job done. Much thanks, thats a new one of the belt, pretty lame I'm sure but very much appreciate the assistance
