IH hydraulic pump 373966 R91

Blackstack · Nov 22, 2010

Can anyone find me any information on this pump number? I can find 373966 R94 listed but not R91. Is 373966 R91 a 12GPM pump or a 17GPM pump?

TIA

It shows to be a 17.0 GPM.

Thanks. Why the oddball "R91" number and not much info available?

The R91 suffix on part number is the first version of that particular pump. As they make changes (improvements) in a part they keep advancing the last digit but it is still same replacement part. Some parts get as high as R99, I think they give up then and give it a new part number at least I never saw a R910.

IH parts system was such that R91 was advanced to 92 or 93 on & on, usually meant nothing but something to IH internally, importance was numbers before the R, they had series of numbers for parts in R1 to R99, later C1 to C99, it would take a lot of explanation for all the variances. I worked for IH-Case-IH-CNH in parts for dealer 47 years, all I would need to hear was 373966R and that told me what pump it was.
