Glad you brought this up Doug.. I've had some pressure to go to a belt drive from other guys running them. And I see they make bearing setups.. so do they normally just run like a small block with a thrust plate of sorts??Not necesary in my opinion. there is minimal fore aft load on a roller cam. Why add the possibility of roller bearing failure? My Jessel belt drive does not use a roller bearing. My 2 cents
The thrust plate for a BB is part of the Jessel front cover and sprocket. It would be a lot of work to fab one up. The button works fine. If using a stock timing cover you can place/weld a spacer that just touches the back of the water pump housing to eliminate cover flex. As stated roller cam lobes are ground with no taper. Thus very little fore/aft load.So, will a thrust plate be something that I would want on my 505/ hydraulic roller? Is it better than a cam button?
