Thread: Ashcroft under-drive reliability for a tourer

Well, certainly took my time to fix the oil leaks.......................... and post a few photo's -

All the bits -



Shiny bit of sun gear runs on a thrust bearing. Doesn't look as if there has been any movement on this surface......however....



on the opposite side of the thrust bearing I have wear on the planetary carrier...................


and the thrust bearing -


Planetary pins are loose in the carrier and two have moved and were rubbing on the aluminium selector fork (Pins are punched each end to lock them in place. You can see the square punch marks in the photo's. I have spot welded the pins on one side) -


You can see the two loose pins about 1-5-2mm further out. The right side is the selector side -


You can see where they have been rubbing in high ratio....about 2:30 and 8:30 positions and where they have been rubbing on the full surface of the selector fork in low.


I didn't get a photograph, but there is a bit of wear on the centre shaft where it runs in the input gear bush.

I have to say there has never been any metal on any magnets in the past, however this time there was a fine smear of ferrous metal on the magnets and aluminium paste in the input shaft area where the oil drains back to the transfer case, plus a bit of thrust bearing material as well.
This must have done 60000km by now, some of it in low low dragging the camper in to areas it shouldn't be. With lockers front and rear, atb in the middle and super low low range, the old girl is pretty unstoppable.

I pulled my one out and sold it, realised I don't need it in the tourer, it needs more attention to ensure all bolts are tight as they loosen itself and I did not like having the weight hanging of that short bolts which are a bitch to access. not to mention the initial problems when Ashcroft deliver it with grub screws which where 2mm to long and allowed a leak to distribute transfer case oil everywhere... for my tourer KISS
