Gearbox is out of the bus and looking at doing a light refurb... mainly to fix oil leaks. Where the gear selector connects to the box, loads of crud and oil leaking. Is it a straight forward fix? The whole cover at the rear is weaping oil. Any gotchas with removing the cover to change the gasket? Drive shaft plates (don't know correct name for them). Mine were covered in crud and muck and think might be weaping oil. Fixable? Shaft into engine. Suspect an oil leak. Again, is this a straight forward seal to replace?
You can pop the nosecone off with no ill effects to change the gasket and seal. Input seal ditto if you take the retainer off and prise the old one out. Knock the new one in with a suitable length of pipe over the input shaft. Driveshafts seals are a bit more hassle, but no big deal. Don't fiddle with adjusters underneath. You'll have to prise the centre caps off and pull the driveshafts out with a puller. When you've done all of that, paint it gold
PS Be veeery careful prising out the nosecone seal, as the casting is easy to crack... With the nosecone off, give the breather hole a good poking out.
Your gear change will be much improved if you paint the gearbox gold. You'll also become far more good-looking and sexually attractive. If you fit a 123 distributor as well, you'll have to beat the ladies off with a stick. FACT.
The side oil seals are easy to replace.. if the CV joint drive cones rock side to side , gearbox needs refurbishment.. Under the nose cone, if it's full of silver oil paste, the visible bearing may have worn into the nose cone. If it has .. gearbox needs refurbishment.. Rear oil seal .. .may need a tool to pull it out and not scratch the drive shaft.. Worth a look but the outcome may be more discoveries...
Oil changed and selecter shaft seal replaced. New gasket fitted to nosecone when put it all back together. Box is back in the van and gear linkage connected...but can't select any gears. When I turn the input shaft, the wheels turn which makes me think that it's already in gear. How can I get it into neutral without using the gear lever?
Tricky, as you haven't got much room. Much easier to work the selector shaft by hand with the box out. Could try different positions of the gear lever to pull/push the selector into neutral?
Excellent. Stick the "t-piece" on as a handle, by twisting, pushing and pulling, should be able to select all gears. Stick it in 2nd before putting it back in (gear lever base vertical).
Turns out that it was in gear but the selector wasn't...hence the problem. Just need another nose cone gasket that only comes as part of a set annoyingly.
