Tweaking repro pushrod tubes so they fit

Post by malmac »

While it is great that there a lots of reproduction parts available it has been my experience that rarely do these parts match or indeed exceed the quality of the parts they aim to replace.

A friend bought these pushrod tubes a good while back from I do not know where.
They were not round and certainly were oversized.

So they got a bit of a tweak today to make them the same OD as the original tubes.
You can observe the lip that is a result of the oversized tubes.
Something to pay attention to when we are doing restorations I would suggest.

Regards

I can’t understand why, if you’re going to repop a part, why can’t you duplicate it exactly? How much harder/costlier could it be?

There were three reasons I chose to modify the part rather than make one from scratch.
1. The parts are not for my bike
2. The modification was quick to undertake and will not compromise the end job
3. It was a freebe so I wanted to reduce the amount of time spent.

In the attached photo I am measuring up a reproduction front bearing carrier. It did need to be modified but as you would appreciate in that case the work involved in making the complete part from scratch would have been very substantial.
