oil pump idler spiggot

[mauricejota7604]

Hi gang back with a new (new years) question, I am putting a larger volume oil pump into my 77 Jota and found that the existing shaft the idle gear runs on is obviously shorter, my question is for those that have done this upgrade,
1.have they put the longer shaft in or run with the shorter shaft.
2. If they have changed the shaft how did they remove it without splitting the cases, I have a longer shaft to put in but the existing shaft is tight in then crankcase, I was thinking of welding a bolt on and slide hammering it out????
Ok better have another beer.

New pump will run fine on the short shaft. The idler gear shafts are a pretty tight fit in the crankcase so if you do decide to change it made damn sure the new one goes in dead square or your oil pump will never run right. Probably best left alone unless the motor is out and split, keep the shaft safe until the engine comes down one day and you can do the job properly.
