I replaced my timer with a new Tw timer.There is still the original felt seal and timer shield. Should I replace them with the modern cam seal and does the old felt just pull out and the new seal press in ? And does the new seal require the timer shield ?
Randy I just replaced my timer with a TW . Since there was no oil leakage past the old felt and seal I left them in. If something is working I leave it alone. The TW is working great !
The news modern seals are not a tight fit. I used a little glue and then put RTV around the edges for a good seal.I have the TW timer and love it.
The area in the timing cover where the seal mounts varies in diameter and occasional this seal fits loosely in the timing cover. To fix this situation place the seal in a vise between two pieces of wood and squeeze front and back sides together which will increase the outer diameter and improve the fit.
It worked for me.
As a firm believer in felt seals for the engine, I left mine in place when I installed the TW. The original tin shield is also in place. I've done a couple thousand km with the TW and it's working perfectly.
If the felt seal is good leave it alone. Ditto the brass plate.
Thank you for all the advice. I will be leaving the felt seal and brass plate in place.
Just be sure that the outer diameter of the brass plate has not been worn down such that it can fall inside the timer. That can cause shorts and all kinds of trouble.
Ideally, the diameter of the brass plate fits nicely in the recess where the timer body rides. The timer body then sits on top of the brass plate, holding it in place. However, over time and use, the edge of the timer body wears away the perimeter of the brass plate, reducing its diameter until it can fall inside the timer housing.
I bought a repro brass plate from one of the reputable vendors a few years ago and it must have been copied from a worn down one because it just fell inside the timer. Vendor said, that's the way they are. It's still sitting on a shelf somewhere in the shop.
I've seen that comment about the repo brass plates before. What would be so hard about getting a front cover and making the plates to fit? Making it right should be no harder than making it wrong. Unbelievable.
