Hey guys, I’ve seen multiple write ups all over the internet!!! No real good advice for changeing out injection pumps on the 332t 3 cylinder. Even called my local dealer today an he said that I was like the 3rd guy this month that’s called asking for advice on how to do it. Basically he told me that I nearly needed to be a NASA engineer to perform the task. Well I’ve sent the pump off for repair an reinstalled it an pulled off the front engine cover and lined up all the timeing marks on the gears , the injection pump has a keyed shaft but the gear that drives it don’t. So I’ve lined up all my timeing marks an locked my pump down on the d try I’ve gear z a n unlocked the locking bolt on pump an all the motor will do is blow off heavy white smoke while spinning the motor over. Want fire up, I ran into this yrs ago an literally performed this same task an just started moveing my injection pump gear one tooth at a time till I got it to run . That was on another guys bobcat yrs ago. This pump times at 29degrees before thc. One guy was talking bout removing injector one an sticking a coat hanger do inside head on top of the piston to find tdc an slowly turn motor backwards till the hanger starts to move down an mark it each time it starts to move then find center of the hanger. Basically I got lost. Tell me how to perform this BS timeing task an im lost. Now you show me an I’ll learn how to do it. Any help would be greatly appreciated. For sure someone has found an easier way, when I removed the pump to get repaired I had locked the bolt down on the pump an told the pump shop to check were the shafts location was prior to disassemble it. So when pump was fixed they could reset the shaft back to we’re it was locked down prior to the repair. Of course they didn’t do it. Thx guys
