1962 990 Implematic Cardan / Clutch Shaft. Out of Position.

Post by gunrunner » Tue Mar 29, 2016 12:13 pm

Having split the tractor to remove the engine to rebuild.The cardan / clutch shaft moved away from the main spline approx 220mm. I have removed the PTO cover and can see the end of the shaft however it will not slide back to its original position it's as if it is hitting something metal.
Is the shaft fully round or has it some splines or something else within that cannot be seen.am i missing something.Can anybody tell me what my problem is and how to remedy it,
Also i am looking for the correct paint, looking through the colour codes
I find that Hunting Pink is 1939 - 1962. Currant Red is 1962 - 1965.
The Primrose Yellow has the date 1958 - 1965.Highway Yellow is 1960 - 1988. With my tractor being a 1962 can anybody put me right on the correct colour for the year. Regards, David.

Place a hard piece of wood on the clutch end of the shaft and hit it with a four pound lump hammer and it will then pass the crown wheel

I have the impression that the hunting pink was the colour for tractors before Implematic and the current red was the colour for implematic. The primrose yellow was the colour for the wheel centres. The highway yellow was the colour for tractors built for industrial and government use (not for farm tractors). I think the tin work and frame on your tractor should have current red and the wheel centres primrose yellow.

Cardan / Clutch Shaft

Post by gunrunner » Tue Mar 29, 2016 8:30 pm

The knocking back of the shaft was considered by myself. Looking from the PTO end it doesn't seem to hitting the cog.Because it is definitely hitting metal and I couldn't see where it was I didn't want to do any damage.Is there any way of knowing exactly what it is hitting.

Regarding the paint colour with my tractor being a 1962, the year that the changes occurred I wasn't sure whether it was the early colour the Hunting Pink or the later colour Currant Red, my serial No. starts with 4428.

There was a question on this before but I can't find the post with a search, from memory the trick was to put weight onto the end where you need to hit it with the hammer and at the same time rotate the shaft. Perhaps someone else knows where the post might be.

When the PTO coupling sleeve on the cardan shaft clears the tight spot in the axle case it will then pass the crown wheel and can be removed entirely if required.
The cardan shaft frequently travels forward when the tractor is split and can be relocated without removing the PTO unit.

Thanks DB2b, & Wheelbarrow for your assistace, It took no more than 1 minute to reposition the shaft. A few taps and the shaft moved back into position, no metal to metal or nothing.I was frightening myself thinking that moving it was going to be a major issue. Thanks once again.

The previous answering post on this question was probably one of mine as this problem appears periodically.
