Here is the engine for the Trump. Some of the dissasemble had already been completed by a previous owner. All the bolts Through the cases were removed and the covers had been off. Primary side had been dissasembled. Cyls had been removed but the head had stayed bolted to the top.
Took the head off all appears to be in reasonable shape. Spark plug holes need some work. One is shot and will have to be welded up retapped. Looks to have been helicoiled once and stripped again. Haven't pulled the valves yet to check the seats but have been told that the hardened seats aren't really necessary so I may just see if these are pitted real bad and let money and time decide.
Next the cyls came off. Should have been 8 nuts around the basebut they were removed by that infamous previous owner.
Pulled the remaining covers off for access to the timing gears and primary side of the engine. The hub in front of the sprocket cover was a real bitch to remove even after heating it up. Of course there was no reference to it in any of the manuals I looked at. I put a puller on it and tightened the shit out of it. Finally it popped off, breaking in the process, so I still am not sure of the propper procedure with out damage.
Got the hub off for access to the sprocket cover. Remove the 6 screws from the cover for access to the sprocket. Sprocket retaining nut is 1.66" and since I don't have a wrench that size I chose to leave it until I got the cases apart. The wrench to remove this will have to be ground down to fit or you can use a socket through the hole from the cover.
To remove the timing pinions I used my harmonic balancer puller with 2 bolts ran into the threaded holes in the pinion. Worked out great.
For the crank pinion I drove it through after the cases were split. It only took a few light taps and I was able to pull it off.
Remember the cam pinions are both left hand thread and the crank is the normal right hand thread.
These pics aren't very good, but under the inner tranny cover are two hidden bolts, circled, that have to be removed in order to get the cases apart.
The cases are finally apart. This is where I drove the pinion off the end of the crank. It's hard to see in the small pics on this page but I found a chunk of piston ring setting down here directly under the counter weight on the flywheel.
Upon removing the crank I ran across something I have never seen before (besides the bottom end of a Triumph engine). The rods are aluminium but the end caps appear to be cast. Has any one else ever seen this?
I have now been told that it is normal to use the cast end caps as if you don't you loose the crank balance.
Time to get some inspetions done and get some pics of that. Hope to get this beast on the road next summer.
