Using a bag-model calculation for $h_1$, we calculate its intrinsic uncertainty due to renormalon poles. The result is given as a function of Bjorken-$x$ as well as for the first moments separately. We also extract the perturbative corrections to the first moments of $h_1$.13 pages, latex, including 2 figures, 19 references, clearification of terminologyHigh Energy Physics - Phenomenologytext
