Foton 404 PTO.docx (317.11 KB)
Hi all.
I've had this tractor since new in 2005 and worked out most of its peculiarities and fixed what needed fixing with spares always available from Affordable Tractors in the USA or Circle D here in Australia. I have the parts manuals for it. The latest issue is that the PTO is not engaging. These tractors have a two - stage clutch and two selectable PTO speeds. I'm confident that the two - stage clutch is working and sending drive to the gear selector which is beneath the three point linkage mechanism and immediately behind - and in - the final drive casing. It's"trying" to engage but won't. The input shaft (see photo) is turning when actuated. I understand that sometimes the roll pin fails. It hasn't on this occasion. I've not yet pulled it apart but will. I'm assuming that the dog clutch inside has lost some teeth or all of them. The parts manual is mildly helpful at showing how it works but it looks as though it shuttles to select either Low - Neutral - High PTO speed with the gears engaged the whole time. The dog clutch would seem to be the culprit.
I was hoping that one of you fine folk have better knowledge of what lies in this area. I'm expecting to pull the 3PL casting off to gain access to the final drive casing and see for myself. I'd appreciate any comments and any photographs of the internal PTO selector mechanism please. It will be helpful to me.
Many thanks and Merry Christmas to you all. Chris
