Author Topic: Grease leakage Vic 5 shutter box Thomas Jonsson Expert Film Handler Posts: 216 From: Bromolla, Sweden Registered: Sep 2003 posted 09-28-2004 03:13 PM                       I recently replaced the shutter gear box in one of my Vic 5. Today I discovered a large portion of grease on top of the "filling hole screw"(are those the right words?). The screw was properly tightened. Could heat have caused the grease to expand so much it was squeezed out of the gear box? I use a 4kWatt lamp and no water cooling. The projector head gets quite hot.

(like when you first unwrapped it from the packaging?) I just installed a new shutter box into one of my V5's and it had grease on it, i just wiped up the excess with a rag and nothing has leaked out since. Is yours the rubber encased one with the metal gears opposed to the metal cased one with nylon gears?  |  IP: Logged Thomas Jonsson Expert Film Handler Posts: 216 From: Bromolla, Sweden Registered: Sep 2003 posted 09-29-2004 12:34 PM                       Found out today that it´s some kind of safety valve that let´s out grease if the preasure gets too high. So what happened is quite normal. I used to have the gear box with metal gears, but it was very noicy, so I had it replaced with the one with nylon gears.

I have a question. Should I remove the valve's holder when change the shutter grease? I've been told to remove the entire valve or the shutter can be damaged. But the "valve" consist in a little hole that allow the grease to leak out... What is the purpose of removing the entire valve? Perhaps the little hole is not enough to evacuate correctly the grease and this can damage the shutter? I have a shutter that is leaking grease everywhere and I been told that I damage it in this way...

The Mobil 1 gear grease is the synthetic equivelent to 90 weight gear lube... the type thats used in many auto differentials and the synthetic stuff would take the high temperatures of your 4kw lamp indefinately without ever changing it. In fact, they would probably run for ever with that stuff in there. Normal heavy grease makes no sense at all as Phil Blake point out "it will just fly off the gears" and then they are essentially running without any lube at all on them. Synthetics are the best there is and not very expensive as compared to the price of that gear box!! Mark @ CLACO Live On Vacation!!

Does it work with both nylon and metal gears? Thomas  |  IP: Logged Rick Long Jr Expert Film Handler Posts: 211 From: Toronto, Canada Registered: Jul 2000 posted 10-01-2004 07:19 PM                     Definetly go with the synthetic gear lube. It works just fine with the nylon gears. Just fill the box to about the halfway-point on the shafts. Any more and it'll leak past the seals. I've replaced so many I've lost count, but with the gear lube, they definitely last longer.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 10-02-2004 01:30 AM                     "Definetly go with the synthetic gear lube.

There are different gear combinations in the vic 5 and they do have very specific lubrication requirements I beleive there a re 3 or 4 different lubes depending on the gear box One type does not fit all  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-02-2004 01:51 AM                     quote: Gordon McLeod One type does not fit all Er ahhh wrong Gord! The synthetic stuff is far MORE compatable with all the situations and versions of that gearbox than any other lube around. Mark @ CLACO Live On VAcation!!

The gearboxes themselves have had some changes/improvements over the years, but the gears are the same (save for the new metal ones). Either way, I'VE found the ones I put synthetic gear lube in run quieter and last longer. As well, every manual I've ever seen lists only the above part numbers.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-02-2004 08:26 AM                     Rick, There are only two gear boxes that I am aware of, its just that Gord is too stubborn to admit that synthetic is better... . He has anti-synthetic printed all over him for what ever reason....you can see it between his smile.... . Perhaps its just that extending the life span of something cuts into the servicing buisness a bit... . I don't know for sure why but perhaps someday he will come around to it all . Perhaps the Vic 5 could go the Christie route and dispose completely of the gear box and follow the belt route . Mark @ CLACO LaVezzi Oil...

The steel and nylon are curent. At heast you've changed over to gear lube... now to get you to use the good stuff. Mark  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.
