HI all, Hope the weather is starting to cooperate where you live. We had snow twice last week, although it didn't stay around.
I have to replace the quick attach connections on my loader.
US parts diagrams show the original quick release collar mounted on the controller as 75532-66323. (the part prefix is different here in Canada)
It has been superseded by 75532-66320 and again by 7J612-66323.
75532-66320 (K2581-66320 in Canada) is the only part available here.
When mounted, the two collars actually contact each other with no space between so you cannot release only one without releasing both.
When looking at pictures on the 'Net, some of the 66323 look more like my original parts and look smaller in diameter.
Can anyone confirm if there is a slightly smaller diameter quick connect than the 66320?
I contacted Messicks but they can no longer deal outside the US. 20210419_154708.jpg
