Water pump removal was created by James Cowart
Im,trying to remove the water pump from a Lycomimg 2H engine. How do i remove it from the front timing chain/gear area? Ive no experience with these shaft driven pumps and generators.
Thanks

Stop, it looks to me much like a L-29 water pump. My guess is that on the timing gear side there is a gear on the end and if you do get it out you will drop the timing chain into the case and will have to take the front of the engine apart to get the timing chain back in position. I think the pump will come off without taking the timing gear side housing off. Please someone with more Auburn knowledge comment.

The pump shaft has a slot to drive it. If you split the water pump impeller housing the shaft and impeller, bushing should come out. Please check with others to confirm.

This topic is also out on the AACA site :

The bitterness of poor quality remains long after the sweetness of low price is forgotten.

Thanks everyone. The reason for removing the pump is that the gland nuts have shattered in place and BOTH need replacement. So if anyone has recommendations on who to contact for gland nuts, please let me know.

So the front of the water pump is slotted and mated to the gear and pulley on the front of the timing cover?? And it should just slide backwards thru the bearing housing? Well, the water pump is corroded solid and i cant split it so far. Ive got it full of evaporust and gently tapping. If in fact you have to take the timing cover off, id also have to get the flywheel off and a pulley which has also cracked into 20 pieces. So waiting on evaporust.
Thanks
