Yep. Those bolts on the front gear hold the thrust plate, the rear (of the two) thrust needle (Torrington) bearings, the thrust washer (It's a flat-style washer minus the bevelling on the inside), and the front stationary gear.



The gear won't move around and around by the way; you'll see that it bolts on in only one position via an indexing pin that's cast on the front iron housing. Both gears are made like this; the gears are called 'stationary gears' and they remain stationary with respect to the irons. There's a gear on the front sides of each rotor that corresponds with these stationary gears; as the rotor rotates in its fashion, it's kept in its elliptical rotation perfectly and exactly by the action of these gears.



If you can, try using a smaller pry bar on the underside of the gear to see if it moves or not. Do not use alot of force and only use a prybar up against the bottom of the front iron housing and not using a gasket surface, etc as leverage.



I suspect the front stationary gear bearing is seized to the eccentric shaft; it's either spun from over-revving (less likely) or 'bonded' itself to the shaft from oil starvation (more likely) although I haven't seen any big signs of oil burning (varnish), etc.

This reminds me of a webpage I was going to make yet never did (yet). During one of my engine builds, I took a bunch of pictures of all of the front cover components together, separately, and then during installation when building the front cover.



The link is -- http://bdc.cyberosity.com/pictures/1...CoverAssembly/

Perhaps someone with motivation and web skills could build a technical page utilizing these pictures to clear up some confusion and help teach a few people how all of this mess goes together, how the torque specs are, etc. etc.



Anyways, here's a couple of pictures showing what we're talking about:







This picture shows the front cover and front iron completely disassembled yet the bolts holding the front gear are still on. In the middle of the gear, there's a white ring -- this white ring is the bearing that's pressed into the gear. The gear and its bearing remain stationary while the crankshaft (centre of the bearing) rotates in and rides inside of that bearing via a bearing race.







Here's a picture of the front stationary gear with the bearing inside of it bolted to the front iron housing from the housing







The e-shaft has four bearing races -> the furthest one on the left is what rotates inside of the front gear bearing.



This clearing some stuff up, hopefully? If that crankshaft bearing race seizes to the front gear bearing, then the engine from the centre iron to the front iron won't separate -> you won't be able to pull the gear off because the rear rotor bearing race on the crankshaft, that's now sticking out on the opposite end of the centre iron housing, will try and pull the housings together. Conversely, you won't be able to lift the crankshaft up from the centre iron because it'll be trying to pull the gear along with it backwards, which won't happen.

in that first pic of yours, you have the spacer on the eshaft, that must be stuck on there jammed thats why the eshaft is nto sliding out fo the front gear. u might have the spacer stuck on the shaft try to take off that spacer, if it deosnt come out then u just spun it. which means the only easy wasy to take it of is grab it with somethign such as robogrips and tryign to twist it or just grabbign the eshaft from the other side of the engine and bang it toward yourself a few times till that spacer slides out.

By "spacer" I assume you're meaning thrust plate as refered to previously. I did remove that, it is just the stationary gear has seized onto the front gear bearing that will not move/slide anywhere allowing me to pull the shaft out.

lsnapcasel

Well, crap. Now what do I do? BTW, I have no idea what made this engine seize (oil/high rpm)... it was bad before I got it. I'm just taking it apart for fun (and frustration)

kahren

its called the spacer not the thrust plate, look in the manual for clarification, i am willign to bet thats it. but if you did take it off then it coudl be as u say, the gear bearign might be seized which i doubt.





here is a pic of the spacer

BDC

I have no idea how you could get that thing off.

lsnapcasel

I can't really tell the size of the one in your pic, but if it fits perfectly onto the front cover side of the e-shaft behind the thrust plate and the needle bearing, then I have removed it.



Like this one:

kahren

there is a letter on it, and in my pic there is an apex seal right next to it.

it kinda falls inside those pieces that are shown in your diagram, needle bearing etc.
