For engine parts you must determine the engine in your unit...an old parts catalog lists both the Wauk XA (31/2x41/2) and XAH were originally installed (35/8x41/2)...Wauks usually have an ID tag on the lower part of the driver side block, but don't know if IH let them put them on...someone here will comment...
Caveat: old time/old line truckers loved to swap engines for more power etc, so you may not have original engine...
Look for 3"x4" or so metal "tag" attached to block somewhere; if none found take off all stamped/cast numbers/letters found and post here for advice/sympathy...
XA/XAH were widely used in ind'l/comm'l uses (gensets, pumps, free-standing power units etc), so if NOS NLA should be used pieces around...
Wauk Eng Hist Soc--wehs.net--will have latest manuals (many (all?) Wauk manuals issued in "editions" as updates). Wehs always sends latest edition---they have no parts, but are always helpful and/or sympathetic, such as advising if both engines used same oil pump and/or if your oil pump (assuming you have a Wauk) was also used on any other Wauk engines (makes searching easier)....Good luck.
