STEPS E8000 Motor Service

[Marc_250]

It's a little over a year and 8000 or so more miles since my motor started sounding rough and I subsequently rebuilt it (new bearings and grease). Coming back after a 50 odd mile ride earlier this week it occurred to me it still sounds as sweet as a nut. There was some debate around grease at the time, I used PG-75 (from bearing man) and can only assume it's doing an excellent job.

Damn been a minute, many thousand problem free miles (bikes showing 12.5k miles but the wheel circumference has been set to min size since drive units day1 so would think it's into the 20k miles) later since the rebuild in October 2022 the 6808DD crank bearing started to collapse whilst out on it yesterday. Nursed it home took it apart today banged in a new bearing and it's good again. First time looking inside since the last rebuild and the PG-75 had kinda 'gone' i.e. little visible white stuff however seems it was still doing a good job, cogs seemed 'oily' and it hadn't burnt like the factory stuff had and all the cogs still seem in good condition.

One dead bearing:

How the grease cogs held up since last rebuild

Maldita sea, ha pasado un minuto, muchos miles de kilómetros sin problemas (las motos muestran 12,500 millas, pero la circunferencia de la rueda se ha ajustado al tamaño mínimo desde el primer día de las unidades de transmisión, por lo que creo que está en las 20 000 millas) después, desde la reconstrucción en octubre de 2022, el cojinete de cigüeñal 6808DD comenzó a colapsar mientras estaba en él ayer. Lo cuidé en casa, lo desarmé hoy, le puse un cojinete nuevo y está bien de nuevo. Primera vez que miro por dentro desde la última reconstrucción y el PG-75 se había "ido", es decir, se veía un poco de cosa blanca, sin embargo, parece que todavía estaba haciendo un buen trabajo, los engranajes parecían "aceitosos" y no se habían quemado como los de fábrica y todos los engranajes todavía parecen estar en buenas condiciones.

22375 miles bravo Marc

Ha thanks I couldn't remember what the minimum wheel size was (to do the math) and couldn't really remember how/be bothered to connect the app to the bike to see! This is my second drive unit first one was warranty replaced around 18,000 miles so the bike has done roughly 40,000 miles total.....
