I've noticed a persisting small oil leak coming directly from under the intermittent housing, operators side where the intermittent sprocket shaft goes through the case. It's not "pouring" but is starts leaking after about an hour of operating time and stops when the projector is turned off.
I'm assuming it's the intermittent seal.
My question is has anyone had this issue and how much trouble is it to replace? The manual has a step by step tear down, build up section but that doesn't tell me how much trouble it actually is.
Can anyone comment on the complexity of the repair?

It's almost exactly the same as an FP-20 and I've done several of those. Not hard if you have some technical abilities.... Its good to also replace the shaft when you replace the seal because you'll find a ring of wear on the shaft where the seal lip has been riding... A new seal may get torn up by that wear spot or it may never seat properly. Other then also replacing the sprocket shaft it's pretty painless. Its also very similar to a Ballantyne Pro 35.

Thanks Mark.
Best source for Kinoton seals and shafts?

Posted by Mark Gulbrandsen (Member # 72) on 03-17-2016, 02:41 PM:

Boston Light & Sound is the only source now that I know of. Some dealers might have stuff laying around....

Depending on the dealer, there may be a direct contact with Kinoton Digital Solutions, that may have stock as well. I'd start with either your dealer or BL&S though.

You really need the seal fitting tools Kinoton sell/sold to dealers, or at least some sort of equivalent. In a pinch I've used the best fit I could find from my socket set. It's important that you drive the seal in on it's edge, thereby not distorting the lips.

Also, good practice is to lubricate the shaft before insertion, that way the seal doesn't start up dry, which is what damages a lot of lip seals.

Dom, here's a trick that has got me out of trouble with a leaky oil seal a few times, at least until it can be renewed.
Drain the oil, put a tablespoon or so of automotive brake fluid in, then refill to normal level. Not anything fancy in terms of brake fluid, none of your new fangled silicon stuff etc. It contains an ingredient which slightly softens rubber seals and causes them to swell. I've done that on a handfull of Kinotons/Phillips over the years so that they can continue running without making a mess until I got there to fix it properly.

I finally stripped the entire film track unit completely off the projector and discovered there was an O ring which seals the oil in the intermittent housing (non operators side)that had become hard and brittle. Found the O ring at the hardware store for 89 cents, replaced it and the leak is fixed. Neither of the front or real sprocket seals were actually leaking.

Only concern I would have about the hardware store o-ring Is what it is made of. Real rubber and oil do not get along. Neoprine is okay. Some stuff made for water can be real rubber.
