excellent....thank you for your responses

by the way, the little bevel washer/spacer 4K3916 that goes in the masterpin assembly is no longer available....guess that's the joy of older equipment

I see some listed on www.Machinerytrader.com if your in need.

Many thanks O.M.
Just moving on now to the blade lift cylinders....point for clarification. I removed the rod from the cylinder, whipped off the rod endcap and the cylinder seal group, now when I pulled out the seal stack (5 or 6 seals compressed in by the gland end-cap) that keeps the oil in the cylinder they had the lips facing outwards, not towards the pressure side. Is that right? Surely the lip should face the pressure.

Doesn't sound right to me. If it's the chevron seal stack type the open end of the V's should face the pressure side. Only the outer (wiper) seal faces outboard.
Later units use the three seal type head.
Inner buffer seal (square)
Middle "U" cup (lip facing oil)
Outer wiper seal (lip facing out)

Old Magnet,

this is literally how they came out of the end-cap....with the lip facing outwards.....like you I thought this was wrong, but didn't know if maybe they had a unique design....I haven't put it back on the machine.....if the consensus is as you say then I will put them lip to pressure

this is as they came out......

This is how they should go in:) ........monkeys have been there before you:rolleyes: Nice catch.

excellent...thanks very much Old Magnet
