J type overdrive planet carrier "Tin hat"


Recommended Posts

Hello,

I am in the process of cleaning and overhauling my J type over drive, it was basically contaminated with swarf following a counter shaft bearing failure.  Clean up has gone well so far, and the majority of the parts look in good shape. 

The needle roller bearings in the planet gear carrier need to be removed for cleaning, to get to these, I had to remove a "Tin hat" from the carrier, this was rather tight to get off as it was peened into a slot around the circumference of the carrier unit.  After prising it off it is now a bit of a loose fit on the carrier.  I haven’t been able to see a spare one of these for sale in the usual places, so I was wondering what other folk usually do with this to get it back in place and fitting snuggly again?  (It purpose seems to be to prevent the dowels holding the planet gear spindles in place from coming out)

Thanks in advance for your suggestions.

Tony

Hi Roger,

ORS were  GKN Laycock and know who were the original suppliers! Also they make a lot of the original parts themselves as did Laycock, they were very selective as to what plant and equipment they took with them and they sell parts to other parties! In my view its far better to send the unit to ORS for overhaul as they have years of experience  and all the parts and they have an original test rig where they set up each unit to make sure it works correctly before dispatch. You cannot do that in your garage at home????

Gents,

Thank you for the above replies,  I have done a bit more digging on the internet this morning, and found out the part is an oil catcher.  Once I found its proper name, I managed to find a bit more information about it.

This Volvo web site shows the part on its exploded view.  (Strange its not shown on the TR one?) 

Its part No 19.

And this web site describs what it is for in some more detail.

Fortunately I took mine off with a bit more care, and hope to be able to recover it with a bit of carful tin bashing.  After that I will have a go at rolling the material back into the slot on the lathe and see if it looks tight enough.

I was wondering if these parts became optional or obsolete at some point, and perhaps that is why we don't see them on the TR parts diagrams?

Regards,

Tony
