Road Test

Richard recently completed a test run of 10,883 miles. The test consisted of a trip from central Texas to Alaska and back. The bike is a 2013 TriGlide. The bike and CycleStream trailer was fully loaded and they rode 2 up and even carried their 2 Chihuahuas in a carrier on top of the tour pak.

We installed a new-out-of-the-box #42200064A comp assembly. No modifications were made to the assembly. We installed a CompenSaver Oil Delivery Tray and our new Composite thrust washer. The comp preformed stellar and remained quiet from beginning to the end. Following are pictures of the assembly after the 10,883 hard pull miles. This ride produced far more stress on the comp assembly than any normal use would experience in considerably more miles. The results speak for themselves.
The primary as seen when the cover was removed. The oil had been changed at 4,974 miles at about the half way point in the trip.
The composite washer before removal
The magnet in the Oil Delivery Tray is doing its job very well. A cleaning with an air hose and it will be ready for the next ride. It can collect debris for a very long time before cleaning so saddle up and run the miles up and when it is time to pull the cover for whatever the reason then clean the magnet. This will assist all the components that live in the primary cavity. We are finding that with the large reduction of wear over the previous versions there is much less debris to collect.

The only place we found any collection of debris was at the intake retention groove. The amount was minimal However the material was accumulating and does need to be cleaned out. I would suggest at about 35,000 to 40,000 miles. Otherwise it is possible the build up could clog the intake holes What had been passed through the intake holes to the interior was later discharged out the oil reliefs in the thrust washer. We found no evidence of this debris at the rear of the sprocket sleeve and shaft extension. It appears the oil flow is in adequate to push the debris past the holes that supply the sprocket bore.
The retainer and sleeve are in perfect condition. Oil supply has been very good. No debris has collected. The dark ring is stain from the oil that is flowing through the thrust area.
The thrust face of the sprocket is perfect. no signs of wear marking just slight polishing and no indication of over heating. The sprocket bore is also perfect.

The composite thrust washer looking at the side that ran against the sprocket face. No wear just a slight polishing. The oil reliefs are running the same as the sprocket grooves but have added purpose to the design. To get oil to the working surfaces but as important to give the debris a place to be discharged. A curving design as with the previous versions would lock in the debris causing it to collect and eventually stop the flow of lubrication. Also the thrust is flat as apposed to the curved design of the spokes making the total function far more useful, quiet and durable.
The composite thrust washer looking at the side that ran against the retainer face. Same great results.
Sprocket spokes are in very good shape given the new grooved design. With the Oil Delivery Tray supplying a generous and constant supply of lubrication the service life will be far greater than that of the OEM design.
The cam ramps are wearing exceptionally well with the CompenSaver kit installed.
The cam splines are performing exceptionally well. There is no signs of wear with a generous and constant supply of lubrication. Pictured is the acceleration side of the splines which takes the most abuse.
comp-study13 The shaft extension shows very slight flow pattern from lubrication that is making it to the rear of the assembly. This is clearly inadequate to serve the high lubrication volume needs of the as-cast working surfaces of the ramps and spokes. Nor is it adequate to provide an acceptable service life for the cam splines. Review the retainer and the oil flow stain that is at the center of the thrust washer area and it is clear the flow differences. Keep in mind this is with the substantially increased oil supply from the CompenSaver available at the intake area.
