Suction Hose for Cat 307SSR

[Jon Martin]

Hi folks. Can someone tell me the part number for the hydraulic pump suction hose for my '94 Cat 307 SSR (Serial # 2FL00541)? The photo shows where I had to cut the elbow in order to remove it - the fitting that threads into the tank let go instead of the hose fitting and this was the only way to get it out. The hose was leaking due to chafing on another hose so it needs replacing.

Youll have to take it and have it made the part numbers from the jap book dont work out in the cat system for hoses

In the diagram, is this the lower hose that goes to the pump?

 

[Jon Martin]

yes, lower hose #26

Also, I think a slightly longer straight hose would work if anyone knows what the hose ends/fittings are?

The hose part number in the Japanese system is Z343347053.
There's no information about the hose or its dimensions. However, there's some good news: elbow #27 has the Caterpillar part number 5I-4332, so you can use that to search for thread information. Connector #24 also has the part number 104-8967.
