I am a new tractor owner and a school bus diesel mechanic. Picked up this B5100E for $900. It run but has a lot of blow by. I installed an oil pressure gauge and has about 20 psi oil pressure at 1/2 throttle and no oil pressure at idle. I have removed the pistons and one of them has a broke ring land and ring. (explains the blow by) I've read on hear about the plug in the rear of the camshaft causing oil pressure issues. I was going to remove the front cover but I don't have a socket for the harmonic balancer. It needs to be a deep well thin wall socket. Does anyone know what size it is so I could pick one up. Its recessed in the balancer so I'm unable to get a measurement on it. The manual shows a special tool #29. I'm not sure if that's 29 mm or not.I don't want to buy one if I don't have to.
Thanks for any help,
Micah
