Plunger Engine Sprocket
« on: 02.01. 2014 13:09 »
I purchased on Fleabay ann A7/10 plunger engine sprocket and cush drive. The sprocket is a p*ss poor fit on the crank sleeve - its bearing diameter is some 0.038" bigger than that of the sleeve. Please tell me they're not meant to be like that and that I've been sold the wrong bits.

its bearing diameter
Very fine tolerance here between innersleeve and sprocket, just enough to rotate freely and allow for some oil to find it's way. Does not have any bearing (or you probably mean it's a 'plain' bearing). Got one in front of me (see picture), is this what you got?

Thanks for that, The sprocket looks the same but the other two parts are different - I shall get on to the vendor.
Cheers

It is very frustrating not seeing a resolution to a problem!

Nourish hasn't been seen here for two years. Hope he hasn't dropped off the radar.
