O-Ring Issue

[MarEng]

I have a 15yo 3510. I have always ordered parts through Big Red Tractor (now Three Rivers) as my local dealer stocks nothing and wants $40 to inbound anything from Branson.

I am looking for an O-Ring for the front axle - Line 16



I have ordered this part twice from Three Rivers. The first time it was too small. The second too large. Should have an ID=~115mm. At $12 a pop (with shipping) I'm not sure I want to test the Goldilocks theory and order again for 'just right'.

Can anybody help me cross this part over so I can order from McMaster?

Thanks in advance.

Brgds, Will.

It's not a cross reference but;

But a 5mm x 115mm for under $6.00
