Das Bike Projekt: Rocker Shaft Suprise.

Well I got the heads back and am now at a point where I can put them back on, luckily I decided to see what condition the shafts and bushings were in. It looks like when the previous owner put the engine back together that he used a LOT of sealant on the jugs. So much that the oil passages in the block were blocked and the rockers galled from lack of oil. They look like an old Edison tube recording.  Also the rings that go around the “towers” that the rockers are on were just plain missing! Another setback, and another parts order! When he said the engine was getting “a little noisey” I can see why. The valve lifters are also a little beat up, new ones will go in!

The Worlds Most Expensive “O” Rings! And notice that there is a part missing?

The “rings” that were missing!

The picture really does not capture how shot these were.

New used rockers with inserts from the box of parts I got with the bike.

Next up: Updated breather, and buttoning up the engine.

Das Bike Projekt: Timing Chain

So, as I continue the ripping the engine apart, I tried to think of what I needed to do as I took the different sub assembly’s apart. Up front we have the timing chain and tensioner, the front crank bearing, the sprockets, and various seals and gaskets. As long as I am in there, it is all getting replaced.

The cover, the seals will be replaced, what a complex casting…

The back, cam and crank seals and gasket will be replaced.

Cover off, the sloppy chain and sprockets and front bearing are revealed…

The chain has to be cut off, it has no master link, then the crank sprocket and bearing can be pulled.

Godd think I planned on doing this, the sloppy chain was hitting this boss on the cover and eating away at it.

This is as far as I care to take this apart!

 

New tensioner spring and she, bearings, seals, sprocket and chain with masterlink!
