   * During the 1975 season, the MoCo received several reports of XL & XLCH transmissions with a blocked oil transfer hole in the trapdoor (resulting in little to no oil supply to the transmission). So, they recommended that the dealers remove the transmission oil drain plug & measure how much oil dropped out. If less than 1.5 pints of oil ran out, the transfer hole was to be checked for blockage. This can be remedied by tapping the casting with a hammer and a punch at the hole location (1/2" hole directly below the countershaft hole). Done carefully to prevent chips from getting into the transmission, loose chips may still fall into the hole which will require flushing out the drain hole.

-Used after July 26, 1984 beginning with crankcase #785 208001, will retrofit to all XL models with an alternator and utilizes two slots for removal. An alignment tool (SNAP-ON 1650) or (MAC LF-12) or equivalent in the shape of a crowbar is recommended by the MoCo to draw the access door from the dowel pins. You can use a propane torch to carefully apply heat to the access door dowel pin area. Do not allow flame to rest on any one area for a prolonged period of time and wipe all the oil from access door prior to heating. Insert the hook end into each slot and gently alternate between the slots to evenly remove the door from the dowel pins. ((HD Service Bulletin #M-892 dated June 22, 1984)) It was sold for parts order as a kit including a retaining ring (11006) for the mainshaft / fourth gear bearing assembly and four T-27 screws (2712). ((HD Service Bulletin #M-894 dated September 7, 1984)) The torx screws contained a thread locker in pellet form on the threads which, when the screw is started in the hole, breaks and releases the compound. As a result, the old screws could not be used. The stator is directly bolted to the door by the four torx locking screws at 30-40 in-lbs. The L84-85 stator (29966-84) ((1979-1985 HD Sportster Parts Catalog pg 35)) has 8 mounting holes with only four being used. To prevent possible chafing of the stator wire, you must use the proper holes when mounting the stator. Starting with the upper right set of holes (1-2)  and numbering clockwise from 1-8, you must use holes number 1, 3, 6 & 7. The 85 stator (29967-84) ((1979-1985 HD Sportster Parts Catalog pg 35)) only has 4 holes. The mainshaft fourth gear bearing rests against a shelf in the trapdoor bore while the retaining ring sits in a groove in the door behind the bearing locking it in place. This beveled retaining ring is installed with the bevel side facing the transmission and the flat side facing the bearing.

-  * **The oiler plug should be a tight interference fit**. It should go in and stay in with the engine running and vibrating and carrying on. Upon dis-assembly, many are found to be loose or rather the hole has probably been worn from the aluminum being smashed in and out of a few times without heating the aluminum trapdoor to expand it. This is why you should ALWAYS heat aluminum engine and gearbox casings, wheel hubs etc, with a propane torch before removing or installing bearings. Doing it cold works once, maybe twice, then the hole is worn out. ((Hopper of the XLFORUM http://xlforum.net/vbportal/forums/showthread.php?t=475201&highlight=oiler+plug))

-  * **To fix a loose oiler plug**, you can take the plug to a machine shop and get them to knurl it. That will increase the diameter by a few thousandths. Then re-install it with Loctite. I would use the red, it is the strongest. But you will then need to use a propane torch to break the Loctite to get it back out.

-  * **Late '84 and up trap door does not include a countershaft oiler plug**. When installed in this newer trapdoor in older applications, it may easily hit and scrubb the back of the stator due to being too long. It will either need to be machined down for your clearance measurements or the old style trapdoor must be used.
