Help with Isri seat swivel

[Adrianlle]

Evening. Tinkering at moment and have removed drivers seat on 2004 Westfalia James Cook as it’s always been stiff to turn. ( one of few gripes with an amazing van). I’ve removed the seat itself from the Isri swivel unit and have begun slackening off the bolts that hold the bottom plate to the top plate-there are 8 of them! Thinking I would ask on here if anyone with an Isri seat had dismantled it/ it’s not the sort with a big nut in the middle of the base plate. I ask because afraid when I seperate it all sorts of springs etc will fly out and I won’t be able to reassemble it! So any help appreciated.

Give it a spray with Plusgas which is brilliant at making things work.

Thanks for this. Ive tried all sorts of lubricant in the past but no real difference. In fact I’ve now removed the 8 bolts and discovered that is just a plate. Underneath is the swivel unit itself. It is a sealed unit. An Engineering Shop could probably dismantle it with a Press but looks as if I’m stuck with a stiff rotation. So will have to use the Lockdown to build up my core strength! At least anyone else with such an Isri unit will know the answer now.

I've just performed a similar operation on my Aguti Gis-liner seat during the installation of an Oxford Patriot lock. The swivel consists of two circular plates which appear inseparable . I used an aerosol of silicon grease. The swivel bases have cutouts for the locking mechanism which I used to squirt the grease between the two swivel plates. One plate was turned approx 25 degrees and lubricated again until I'd completed the full 360 degrees. Gradually (I had to perform the full greasing operation 3 or 4 times) the plates became easier to turn by hand. When the seat was reinstalled the difference was dramatic. No grinding noises and easy to swivel.

If I had any sense I'd have taken pics

Thanks I had already decided to spray silicone into every available orifice. So after nearly a full can and much rotating round and round and round it is better. Still a bit difficult to get started but heaps better once the seat is back on. So thank you.

Be careful now ​
