Thanks for the feed back guys, truth be told, I realy don't want to do it in the field, the customer was trying to avoid the extra expence of transporting the machine back to the shop and all the related down time, and I don't blame them for trying to avoid all that. Since not all the seals are leaking, putting feelers out about a field repair seemed reasonable. Next time I see the guy I will tell him that the international council of forklift repair elders give that idea a thumbs down! ;)
