    Default New Nos Speedo Cluster for 90 CV question.

    I am ready to install the Nos 140 speedometer cluster I have for the police 90 CV. The new one has the original gears which do not have any lube on them. I did want to use what is there if I use the proper lube. I would ideally use synthetic lube however I do not have anything other than spray. That won't last. My next choice could be a dielectric silicone grease. Next choice could be a Lithium grease.
    I would rather get the synthetic however the stores are closed due the State's stay at home mandate.
    I also would rather not buy the replacement gears since the new ones look perfect.
    Suggestions please.

    I've been using white lithium grease on my gears, but I also have replacement ones in my cluster, so I have no idea how that would affect original gears. I just recall the originals were more waxy, or at least they felt that way when they got crumbly.

    dielectric or lithium should be fine, just needs to be thick enough to not run off, but not so thick that it will jam up. The original plastic gears in the Mark VII odo I had apart recently felt like some sort of silicone grease. Don't need much, just a very light wipe to coat stuff. Where the Mark VII piece failed is the pivots that the gears turn on. The lube in there got gummy and the odometer got sticky enough that the little motor wouldn't turn them. I wonder if thats the root of the failure on Vic clusters. Fixed it on the VII with a couple drops of sewing machine oil on the gear shafts. Thats 30 years of Florida heat vs sitting in a box somewhere though, it probably had a rougher life in the car.
