IDK about the IH part (# 78 055 C1), but I believe it's a 4 1/2" pulley with a 3/4" finish bore and a 3/16" keyway.So is the 5/8" pulley available anywhere to convert a standard QA42A to a B?
I see Charlie has the curved upper links available.
I'd sure like to install the QA42A on my smoker this winter.
I don't think it affects the lift height at all. None of the CC blowers lift high. It's not until you get to the 3000 series that things really were done right, IMO. Everything else is rube goldberg contraptions.I checked and it is a QA42A. The reason I wanted to trade them out was two fold. It is on a 149 so I wanted the straight arms to be "authentic". The other reason is that when I lift the unit, it has very little clearance. I was thinking the curved linkage affected the height and if I switched them to the straight arms, it would increase the clearance. Maybe I just need an adjustable lift rod to be able to raise it higher?
