Raleigh, perhaps, making change on top of wheel (6)
I believe the answer is:
walter
'raleigh' is the definition.
(I know that raleigh given name Walter)
'change on top of wheel' is the wordplay.
'change' becomes 'alter' (altering is a kind of changing).
'on' means one lot of letters go next to another.
'top of' indicates taking the first letters.
The initial letter of 'wheel' is 'w'.
'alter' put after 'w' is 'WALTER'.
'perhaps making' acts as a link.
(Other definitions for walter that I've seen before include "Sir - - Raleigh" , "Sir --- 23, novelist" , "Bruno ---; --- Scott" , "- de la Mare, English poet" , "Sir . . . . . . Scott, famous Scottish poet and novelist of 'Ivanhoe' etc" .)
