Rockers
Posted: Mon Mar 25, 2019 7:56 pm
Hello!
This is my first post here.
Hope to get some help from you all.
I have a Matchless G80 -1948.
Last summer there was a â€knocking†sound from the engine, and after taking off the head/rockerbox, I noticed that the pushrods had knocked into the rockerbox casting.
(Bottom side of oilchannel.)
This I think is because of worn rockers, and me adjusting pushrods too high.
Earlier last summer, when I adjusted the pushrods, they apparently got too long and so they finally touched the casting.
I ordered new rockers but they are longer and also the splines do not match the old ones.
The dealer says he only has this type of rockers for matchless, and that the records show no other type of rockers. Because these new rockers are longer, I see they do not match the holes for the pushrods.
The valve side rockers also seem wrong considering angle against the valve.
My question is:
Are there different types of rockers for Matchless engines?
I do not know how to post pictures.
I have pictures that would help explain.
Maybe someone can tell me how?
