H Farmall timing gear

I"m going to have to replace a timing gear in a '48 H that has had a IH live hydraulic pump installed. It siezed and you know the result. It looks to me like I will have to move the front pedestal ahead to get enough room in front of the crankshaft to get the pulley etc off. Am I right? Also will a timing gear from a Super H that came from the factory with live hydraulic pump fit on this H? I think they are built heavier. Thanks for your help.
 
You will probably have to pull the camshaft and have the old gear pressed off & have your new gear pressed on. Hal
 
Before you can remove the camshaft, you will first have take off the valve cover, then remove the rocker arm assembly, next remove the push rods and then remove the axcess cover on the right side of the engine and finally remove the lifters.
 
Thanks guys, I didn't realize I'd have to pull the camshaft too. What a mess!! Do you have an answer to the timing gear being heavier from a Super H? Thanks again, sure appreciate your help.
 
Don"t count on a SH having a stronger gear. Find one with a number on it that ends with DA or DB. Depending on how the old gear is broke there may be enough of the gear center sticking up from hub to remove with a puller with cam in engine. Only thing is when installing replacement gear the cam needs blocked to keep it from shifting to rear. If installing a DB gear I recommend removing cam because there made for a tighter fit on cam than previous gears.
When removing front cover the oil pan needs dropped anyway to get a good seal between it and front cover. Oil pump is removed before cam along with valve mechanism, lifters raised in bores, and 2 bolts behind cam gear.
Gears from C-164, 169 and 175 engines will all fit a H engine.
