Seat

Got the 105 put together with new updated hydraulic pump. Filled and bled system, fired it up and everything worked as it should.
Thanks to Tim Smith-he saved me over a thousand dollars on the replacement pump. He can them direct from a Vickers supplier. AGCO has a huge markup.
My advice-need a new hydraulic pump, contact Tim.
Now while the 105 was down, we had to run the round baler with the 2-85.
Baling along and the seat went down to the bottom. Tractor is a red stripe and has seat with two springs and a shock absorber between the springs in the seat back. The only way to access the springs and the shock is to remove the adjusting threaded rod and roll the seat assembly up and out of the back. Springs are good and the shock looks like it is bleeding. Before I disassemble, does any one know who made the seat? I thought it was a Bostrom seat. I got the serial number from the seat plate and contacted Bostrom( now owned by someone else) . I have 6 digit serial number and was told that Bostrom seats have 9 digit numbers. So I struck out at Bostrom.
I would like to order a new shock, preferably from the seat maker and not from AGCO.
Thanks in advance for any advice.

Did you try googling the numbers?

take the old shock to napa or other good parts store with someone that knows their job and will take time to look things up.will save lot of money.

Yep -went to the AGCO site. Found out seat suspension assembly is 30-3342697. Shock absorber is 30-3342743. I Googled those numbers and did not get any hits. Will take the seat apart and try the NAPA/auto parts stores like reply above suggested.
Thanks.
