Hello John Player, since we last communicated I have replaced the four seals on the drive axles; bead blasted, painted and installed all new components for brakes and now am concentrating on the noise located in the fan, alternator, and water pump area. Also I have been diligently searching for a repair manual for the 4P Toyota engine. The serial number 01428820 is stamped on the block right under the cylinder assuming to be # 4. I am proceeding with the instructions originally forwarded and so far found nothing significant, at east to me anyway. As previously stated my background is engineering not mechanics and with technical manuals I can fly but without one I seem to be hamstrung. It looks to me as if I am going to remove the counterweight, radiator and fan to get to the pump. I wish to restore the unit to as pristine a condition as possible while having it apart. Knowing what to accomplish is one thing but following a troubleshooting section in a repair manual is quite another. If you should know where I can PURCHASE such a manual I would appreciate the info. The shop and parts manual from a Komatsu dealer was quite expensive but cover almost every lift they make.

I hope this is not to verbose!
