Lionel PW 736 Berkshire Maintenance Question

Yes Rich,it's an oil hole...as for the cover  I just pried it off,but yours looks different then mine so tread lightly....good luck...joe

Pry up on the cover with a flat blade screwdriver, using a lever motion.

The motor does not need to be removed to get the cover off.

The hole in the motor you reference is an oil port for the bottom armature bearing. Use light machine oil.

That cover will definitely come off but remember its been sitting like that for at least 40 years and it is very likely some of the grease may have congealed around the cover's lip and really hardened up.  As stated a small flat headed screwdriver could do the job with a light prying motion.  Failing that I would suggest purchasing a container of Break Free CLP which is used in freeing up jammed automatic weapons by the military.  It comes in liquid and spray forms and it works great.  I have used it many times on engine parts which have frozen up over the years and have never been disappointed in the results.  You can get it on line or even at Dick's Sporting Goods.  Just give the cover's seam a shot of this stuff and let it cure for a couple of hours, maybe even overnight if it won't budge.  I have had the same problem with an old 736 and was able to pry the cover off.  You should be OK.  Also, my advice would be to clean out that worm sump with some CDC contact cleaner and replace that 60 year old grease with a supply of Lucas's Red and Tacky.   In your video that vintage 736 runs really smooth but a new supply of lubricant will enhance its running characteristics.

@ADCX Rob thanks, did you scan the instruction sheet or is there a web library that I don’t know about?

@OKHIKER thanks I will give it another try. I was contemplating using Red N Tacky, even through I never used it before, was reading threads yesterday on it. 

@TrainLarry and @joe krasko thanks appreciate the response
