Need help Jelco 370 cueing

[papabearjew]

Anyone familiar with adjusting cueing on a Jelco 370 tonearm? The cueing has a very limited travel and won't consistently cue down far enough to make contact with the record surface. It's erratic.

I got it adjusted properly but the travel hangs up. (It sticks).  When I go to lower the arm it will start down, pause up to 30 seconds several mm above record service, and then lower all the way down. To replace the cueing cylinder is about $60 plus labor. It appears the tonearm needs to be removed from the plinth to accomplish this. It might also be possible to clean and relube the cylinder to correct the damping but it still needs to be removed from the tonearm assembly which doesn't look easy.
Any suggestions?
Thx

I'm not familiar with those arms, so I could be way off base. Does it use fluid in the damping cylinder? If so, is it possible there is an air bubble in there?
