Thread: PTO Shaft Thomas Winch LT95 bottom mount

Years ago I got all new uni joints and a bearing block for a Series PTO winch. They were all standard off-the-shelf stuff for industry use and no doubt still available now. I did have the original shafts but you can buy them, even with a keyway machined right down the length of them so that you just cut to length, fit the key and uni joint yoke, and there you go. Industrial suppliers are the way to go.

Thanks everyone - I'm trying with the industrial suppliers now - will post here if I have any luck.

Cheers,

Matt

Does anyone have the exact length for the steel shafting? Also I know the bearing blocks and UJ's are available off the shelf but was hoping someone may be able to help me with some of the specifics ( sizes etc) to take to the machine shop, excuse my ignorance here - I don't have one on hand that I could copy and I'm not
metal worker!

Thanks!

I presume they are out there it's just knowing how to get one!

hi matt may be able to help jim

Im pretty sure Advance Trailer Spares and Winch Industries did the winch aspect ADF Perentie project.

Advance Trailer spares did the shafts and either the winch or pto end. They still have shafts available for various applications. website below:

Does anyone have the original army parts list for the perentie PTO winch system? I seem to have everything but. It would really help when talking to suppliers.

Cheers

I think I have most of this concept sorted now thanks to the help from you all. The only problem i see is that I have to adapt to this.

It measured it out as a 3.5" diameter flange with a 2" square bolt pattern. I imagine It would also need to be a 3/4" shaft output size with 3/16" x 3/32" keyway to suit the rest of the system. These don't seem to exist as off the shelf items, however I'm not good on the terminology and may be asking google for the wrong thing. Is there a name for these flange to shaft adaptors? Anyone bought one of these before somewhere and can recommend a supplier?

Cheers,

Hi dingsy,

I've taken some photos & measurements for the bottom mount PTO shaft assembly. PTO drive flange mounting surface to end of first shaft length is approx. 525mm (see below). Shaft only length is 470mm. All other measurements are shaft lengths only.



I suspect this is the only shaft length difference between bottom mount and rear mount PTO shafts. The remainder appear interchangeable judging by the shaft bearing to chassis mount locations. My 120 had a rear mount PTO fitted at some stage before I got it - the shaft support to chassis mounting holes line up perfectly. Here's the remainder of the shaft measurements

2nd UJ Yoke (from the PTO Drive flange end) has a considerably longer shaft coupling than all others



Middle shaft length (minus the UJs) is approx. 635mm



Front shaft (the one connecting to the PTO winch) length is 190mm.



Shafts are 3/4" outer diameter and use 3/16" wide parallel keys to lock into the UJs.





Hardy Spicer UJ cross Part number is 5-170X (I had all mine replaced and kept the best old one as a spare)



I also had the complete UJ replaced - don't know the part number but Hardy Spicer just sized it off the old one (pic below if needed)



Hope that helps. Shout out if you have any other queries.

Cheers
