I've been trying to find AFTERMARKET cylinder seal kits for for my BH75 (Serial# 12168) backhoe attachment on my L3400.
The price the OEM wants for the seal kits is an absolute joke. I mean seriously, $200+ for seals? Even the companies that "discount' them to $100+ is still a ridiculous price IMO.

I was able to find aftermarket seals for the swing ($25 each) but none for the other cylinders. Here are the part number that I need. Has anyone sourced aftermarket, reasonably priced seal kits?

Boom 7k501-22300 (qty 1)
Dipper 7k501-32310 (qty 1)
Bucket 7k501-43300 (qty 1)
Stabilizers 7k501-52300 (qty 2)

Thanks in advance.

I was hoping to order online. It's 2+ hours to my nearest hydraulic shop and I would have to bring everything to them. So basically nearly a whole day would be shot.
Your other option is to measure them yourself and order from a seals part place. But you'll have to have them apart to measure. Part numbers won't do you any good.

I do have them all apart already. And I do have all the necessary measuring tools to measure them.

But again, I was just hoping that someone has already been through this expedition and found aftermarket seal kits online somewhere and could send me a link.

If I don't hear from anyone in a couple weeks I'll probably resort to measuring them.
