FD3S Rebuild: Take 1
« on: May 27, 2004, 12:00:59 AM »
Well after my friend got completely ripped off by some Southern hill billy slack jawed red neck trailer trash texan, we have no real choice but to go ahead rebuilding the old engine we took out a few months back now :eek

However on the plus side it means you\'ll all have lots of piccies to look at while we strip the engine, clean, measure, check tolerances and re-assemble it:cool ;)

So here is the first pic:

Loosen main front nut on eccentric shaft then remove all oil pump/chain retaining bolts.

Take out pulley flange and tap lightly with a rubber mallet to break the gasket seal, then lift off.

Remove the oil pump sprocket assembly and carefully lift off the thrust washers, spacers and roller bearings from the eccentric shaft.

Once oil pump is removed and you\'ve left the front stationary gear in with one bolt retaining it, turn engine over so that you are looking at the rear rotor end plate. Undo the rear stationary gear and remove it.

P.S. Disclaimer: these descriptions are to just roughly give a general gist of what you have to do and in what order and are no means real instructions on how to strip down your block:rolleyes: ;)

Using a 1/2 inch 3ft long breaker bar and a 17mm socket, undo the long retaining bolts; to start undo each one by approx. 1-1 1/2 turns ins a criss cross manor.

Once all the bolts are out, knock the end plate with a rubber mallet to break the seal. Then lift off revealing the internals of the rear rotor:bandit

Then take the two dowel pins out at 5 and 11 o-clock. Again knock the housing to break the water seals and remove the rear housing. Then carefully twist the rotor from side to side  to prevent the corner seal from sticking and lift off and over the eccentric shaft.

Now repeat steps to remove the centre plate but you have to lift the shaft up a little to get the housing to come off. Then our worst nightmares become true as we start to examine the condtion of the front rotor and housing:o :( , lol

Now look at the state of the front rotor housing!, something went bang big time:eek: Bits of rotor tip are stuck in the surface and have gauged out massive channels in the nicckle plated surface. Do you guys think it can be sorted with a little elbow grease and some wet and dry?????? ;):rollin

The rotor is just as bad and this thing is made of some fairly high carbon steel:eek:

Now the cleaning up process begins. First off removing all of the old water seals and cack from the side plates. All the plates look in fairly good nick, so fingers crossed they will be within tolerance:)

These rotaries are so much simpler than a piston engine, it can all fit nicely spaced out on my workshop table ready for a damn good cleaing:D
