Repairing Your Lancia Beta Window Regulators



Lancia Beta Window regulators have a tendency to get sluggish with age, as do many other Italian marques.  This is cause by the inferior grade of grease used on the internal mechanism.  The grease becomes sticky with age as the internal oils evaporate and the residue actually sticks the regulator, impeding its ability to work over age.  The same sort of grease, with the same sort of result, is used in the starter solenoid.

So, if your windows are still operating, but too slowly, refer to Operation 1, below.  If your regulator has ceased working altogether, refer to Operation 2, below.



OPERATION 1

Lower the windon on which you wish to work to about ˝ down.  After completing this, if your window regulators are electric, remove the ground terminal connector from battery before starting operation.  If you have manual windows, you must now remove the window crank to allow removal of the inner door panel.



Freeing up your “slow” electric windows or manual windows which have become increasingly hard to crank is the object of this exercise.  First of all, carefully remove the inner door panel.  Depending on which series Beta and which model, this may require removal of several different screws.  They will all require the removal of the inner door latch bezel ( or plastic surround trim ).  This bezel on all models will come off when you push in gently while attempting to slide it toward the front of the vehicle approximately 1/8th of an inch.  Once you slide it forward, it will lift off.  Be careful not to break any of the 4 retainers on the back as you take it off.  They are easy to break and the bezels, like a lot of other things, are no longer readily available.


After removal of the inner panel, a plastic vapor barrier will present to you.  Please gently pry the retainers in the top retaining strip.  The vapor barrier will now come off.


At this point, you will see that the door glass is fastened to the regulator with a clamp and a few screws, normally 2 on the coupe and Zagato, but maybe more depending on which model.  Removal of these screws will allow you to free the glass from the regulator mechanism.  After freeing the glass, gently push the glass up to fully closed position and wedge it there, if necessary, to prevent it from being in your way for the rest of the operation



Remove the other screws on three points which affix the regulator inside the door.  If this is an electric regulator, find the electrical connectors, mark them and unplug them (3).  One is the ground, one is one direction and the other is the other direction.  Gently maneuver the regulator from the inside of the door



You will see that the regulator is made of a winder mechanism which is either powered by a motor or a hand crank.  This mechanism engages a worm gear which acts on a long spring.  The spring is inside a 3-sided track and causes the window attachment bracket to move the glass up and down. 


Here is your problem.  The white lithium grease you see on the spring and in and around the worm gear has congealed as the petroleum oils have evaporated over the years of heat and dirt.  You must carefully clean all of this lubricant from the mechanism until it is perfectly clean.  Kerosene, Benzene, or other distillate solvents work well for this.

Once clean, put a VERY SMALL amount of fresh chassis grease on the worm gear itself and work the spring back and forth by using the crank if it is a manual regulator or by using the motor with electric jumpers if it is an electric regulator.  Lubricate the spring itself with a very light machine oil such as 3-In-One Oil, or sewing machine oil.  Do not use WD40 as the lubricant.  It may be used to CLEAN the mechanism, but is useless as a lubricant.


After lubricating the spring from end to end, run the spring back and forth from spring end to spring end, until the speed and/or ease of use is dramatically improved.  At this point, reinstall the regulator in the door by carefully reversing the description above. 
OPERATION 2



If you have a mechanism which does not work at all or if you attempt Operation 1 only to find that your spring has a “gap” in it or is bent or broken, you must now perform the operation above until you have the regulator out of the door.  Clean the regulator spring thoroughly with solvent.  You must now deal with the spring.  You will see that one end is clamped into the window glass bracket, the middle passes through the worm gear, and the other end moves freely inside the chase.  If you have a window spring with a gap, it will cause the glass to go down part way and then seize up.  At this point, you may unclamp the spring from the glass fastener bracket and reverse it in the chase so the the “gap” point in the spring is in a part of the chase where it does not come into contact with the worm gear.  This will effectively and cheaply fix your regulator (one time).  If you did the lubrication properly and re-lubricate the mechanism any time you detect sluggishness, your regulator will last indefinitely. 


If you have a regulator motor which is seized, you must send the regulator motor to a motor shop for repair.  They are otherwise no longer available, but can be commonly repaired by competent motor shops who stock bearings, bushes, and the like.


After dealing with the spring and the motor, reassemble everything and re-install the regulator in the door.  Operate the window several times to make certain you have the glass properly aligned.  This is especially important on the Zagato model and on rear sedan windows in the Gamma and Beta saloon models.  Those glasses track on only one side of the window until nearly closed and track on a hidden metal track inside the door up until then.  This track must be tightly adjusted so that it keeps the glass adjacent to at least ONE track.  Otherwise, the glass will move up into a jammed position and perhaps damage your repaired regulator
