Avoid This Mistake: Oil Pump Drive Shaft Drop
Common mistakes made when building or restoring a classic Mustang, #2
This is the second installment of our Restoration Mistakes series, dealing with common mistakes made when building or restoring a classic Mustang and how to avoid them. As we said in part one, we’ve been horsing around with classic Mustangs for more than four decades and have come to the following conclusion: we’ve never stopped learning from our mistakes nor have we stopped making them. When you’re restoring a classic Mustang or building a hot restomod it is important to see the pitfalls before you find them, not after stumbling and falling into them. Silly stupid mistakes we make time and time again. Whatever your reason for screwing up, we’re here to remind you we have been there ourselves and know how not to make the same mistakes again. Our second tech tip deals with the oil pump shaft.
Oil Pump Drive Drop
We’ve seen this mistake time and time again. The humble oil pump shaft carelessly dropped into the oil pan because the retaining circle clip wasn’t installed on the shaft or the shaft was installed upside down. When this happens you have to pull the oil pan to retrieve the shaft suffering all kinds of time loss and frustration. Always make sure the retaining clip is on the shaft and that the clip is on top at the oil pump pedestal and block. This clip prevents your oil pump shaft from being removed with the distributor. We have actually seen distributors installed without the oil pump shaft.
Zero oil pressure. Zero engine.
