Am after recommendations on removing a filter sump plate on my 750, it’s been on for a long time. Engine is in frame. Three of the nuts came off, the fourth had the entire stud come out. Threads are okay so just need to get a new stud. The green book says to use two levers on opposite corners to push the plate away. Is that best way?

Am not bothered about damaging the plate, I have one of the replacement billet ones with I bought recently.

Thanks
Sean
 
Hi Sean

Give it a bit of heat from a blow torch or paint stripper gun. The tap it sharply sideways, just a BIT - do not use a lump hammer! Left-right-fore-aft. That should loosen things up for you.

Have a look into the holes in the plate to see if they have corroded around the studs.
 
As per Haggis's suggestion, a sideways tap to break the gasket bond usually loosens it. The threads can also catch on the holes in the plate. A wide scraper blade (I made one out of an mechanical hacksaw blade) between the gasket and the plate might get things started (seeing as you'll be replacing it). Billet replacements are far superior.
 
I experienced the same- the oil screen housing and bolts are a tight fit and gently levering side to side will loosen it. And yes , the billet cover is better but cleaning the mesh screen is still a good idea.
 
If the plate was installed without washers under the nuts and the nuts gotten very tight, the nuts will compress the aluminum around the stud hole in the plate and bind on the studs. You will have to lever it off.

Good point, no mount of sideways whacking with a sledge hammer and screwdriver will budge it, if that were the case. Insert the now defunct Bolt emoji here ......
 
Before the hardened washers were eventually fitted it was a right bastard to get my head off. There is this horror story in Engineering called Puncture Shie. Spread that load, washers are a good thing.
