Hi Folks, new here so hope this is in the correct place
I've had my Fourtrak EL since new back in 1989, and it was in daily use until 3 years ago when it went into dry dock.
I've had a problem now for around 8 years whereby the electronic 4wd has failed. I've replaced the solenoids twice but its still failed. In the end I took the unit apart, and tested with a vacuum pump. I found that the I could only just engage the 4WD with a very low pressure vacuum, even after taking the unit apart and giving it a good clean. I did hovever find it relatively easy to "pull" the gear in by hand.
My questions are as follows.
1. Is this a common fault?
2. Am I going about fixing this wrongly?
3. Does this fault mean that I need to change the transfer box?
4. If I've got to got to that length, can I retro fit a manual 'box from an earlier model?
