[C320-list] Perkins M30 water pump

Ditto at about 1500 hrs. Now approaching 2500 hrs. I'm wondering if I'm looking at replacing it again in the near future.

It's always possible that the studs will break before giving way to the wrench. One idea is to use a penetrating oil several times over a period of a day or two, then use an impact wrench to try to urge them out. Harbor Freight will have inexpensive impact tools. A 50/50 mixture of acetone and ATF will suffice as a penetrating oil.

All Perkins parts are expensive in the US. I haven't found it matters who you buy them from. With import duties and multiple handoffs, the prices are what they are. I did find a British company to export an exhaust elbow at a quite reasonable savings and the delivery wasn't unreasonably long.

I had a similar experience on Liberty #128 at 1150. The thermostat also was shot. Was able to pick up both at the local Perkins tractor dealer for a reasonable price, problem was getting pump off the block. Ended up breaking off two studs which took a little extra time to attend to but in the end it was a easy repair. Good luck. Greg

Anyone seen a similar lifespan?
