Author Topic: Poorly maintained Simplex XL seems to have oil leaks everywhere. Where do I start? Randy Bowden Expert Film Handler Posts: 146 From: Portland, OR, USA Registered: Aug 2000 posted 05-16-2008 04:25 PM                     good point Mark! I sorta forgot that on the old XL's I don't even bother with the O-ring, on the front side you have that big fat steel washer with a big fat neoprene washer to go along with it, it's a wolk only part IIRC.  |  IP: Logged Michael Moore Expert Film Handler Posts: 188 From: Dover, DE / USA Registered: Jun 2006 posted 05-17-2008 09:55 PM                        p.s. no not at all  |  IP: Logged Eric Robinson Jedi Master Film Handler Posts: 538 From: Santa Rosa, CA Registered: Jan 2005 posted 03-14-2009 12:29 AM                     I have a Simplex 1050 with an oil leak from the framing shaft on the gear box side. From the parts manual it appears as if I should replace the 51-48024 O-Ring, Oil Seal, but it sounds like Mark was saying I should use a flat washer instead of an O Ring. I think these machines are 1995 vintage. Also, are there more gaskets, seals, or parts which should be replaced on the framing shaft to kill an oil leak?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 03-14-2009 02:36 AM                     quote: Eric Robinson to kill an oil leak? Trade it in for a Christie P35 is the quickest way... J/K! What I've done to remedy an oil leak is to pull the intermittent assembly out and completely dry every surface where metal meets metal of oil using rubbing alcohol on a rag (get the rubber gloves on when you do this-alcohol will dry out your skin real bad..too bad that we can't use "carbon tet" - Carbon tetrachloride - for that stuff dissolved oil quite nicely, but being so toxic was another thing...)...for we old mechanics know that 'oil will always follow oil' when oil begins to leak out of where it wants to. I used to have a very leaky PR-1050, but doing this drying trick, slowed that leakage down considerably. Also, if you have a real main drive seal leaking, then it's time for a new seal kit since that oil seal will get harden up with age and will cut a groove in the drive sprocket rim. -Monte  |  IP: Logged Eric Robinson Jedi Master Film Handler Posts: 538 From: Santa Rosa, CA Registered: Jan 2005 posted 03-14-2009 10:55 AM                     quote: Monte L Fullmer Trade it in for a Christie P35 is the quickest way When have I heard this before? I'll check out the seal kit, do you know the part #?  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 03-15-2009 12:02 AM                     quote: I'll check out the seal kit, do you know the part #? Square tooth driven pulley kit >> 52-60246 Round tooth driven pulley kit >> 52-60251 Now, these numbers are for the recent "5-Star" soundheads made by STRONG. If you, or anybody encounter "5-Stars" made by NSS, there is a thrust washer on the input shaft that must be removed before any of these kits can be used. I worked on a NSS "5-star" head and found out the hard way on that thrust washer...couldn't get that sprocket to align up correctly til I found that washer..and it had to go. hope this gets you going to snuff up some of those leaks. Before you do these kits, drain the case completely and dry up any oil that is around the main drive shaft before putting on these kits. Also, take some RTV sealant on the threads of the six screws before putting them in the mainframe. Also, do the rotation torque sequence of those six screws by: first getting them all down to a light snug, then tighten them down across from one another. (sorry on the light rub about Christies .. had to give you a raz.. ) good luck - Monte  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 06-21-2010 11:15 AM                 It has been 463 days since the last post.  |  IP: Logged Eric Robinson Jedi Master Film Handler Posts: 538 From: Santa Rosa, CA Registered: Jan 2005 posted 06-21-2010 11:15 AM                     quote: Mark Gulbrandsen Install the seal kit that Strong makes for the XL Is there some part number for this kit?  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 06-21-2010 11:37 AM                        See posting above. It is my oopinion that the seal kit is not wanted or needed. If it helps, it just indicated that the instruction manual is not followed as to how much oil is on board. As to many XL leaks, there must be at least 29 seals on an XL. It is just about true that an overhaul is no more trouble than replacing all of those seals.

How many females actually check the oil in their car engine let alonen the projector that generates their wages? They are absolutely necessary in these locations so there is still oil in the machine when the service tech is in for his quarterly visit! Also, Old black wrinkle X-Ls do not have heat treated main castings. So they are very porus and the oil leaks right through the botto of the casting. They started heat treating them when General Precision took the Simplex over. This is the sole reaon why I will never buy or install a black wrinkle version.

You are slightly worse off afterward. What a waste!

Never had any problems with it either.

I'm sure if you think about it you could come up with plenty of theatres managed by men that have poorly maintained projectors.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 06-25-2010 06:25 AM                        Actually the women I have in the booth are unusually good with the small items: cleanliness, oiling, etc. I think they live in fear of mechanical failure. Usually they THINK they have no knowledge of things mechanical. Rarely when things do fail, they ask questions and are just fine about resolving the problem thmselves. Louis  |  IP: Logged
