Vacuum pump--jake

[Blu-meanie]

I'm on the North Coast of California and my vacuum pump quit. Anybody know if:

1. The stock belt will fit without removing the pump?

2. Can I just remove the pump part and leave the pulley stuff and not change the belt?



Seafish... You wouldn't have a pump laying around would you?



At Ocean Cove and there is no cell svc. Barely have internet.

Your stock belt will fit by bypassing the pump. Shad

These pumps are built on the same design that Delco used to provide the pump to Ford for their early diesels that used vacuum for the brake systems and HVAC systems in the dash. .

When I owned a group of these trucks we found the pump would die without warning... we found that if once or twice a year we gave them a spoonful of oil they would last longer and work better... . Low vacuum meant brakes that didn't function well... .

We'd pull the vacuum line from the booster and let the pump suck up a couple of tablespoons of light engine oil and later it would discharge that oil almost as sludge out the exhaust of the pump...

There was nothing in the Ford shop manual about this... but it made sense to lube and allow the oil to carry away the dirt in the pump... I'm not saying its a fix all for this pump. . but those pumps that won't pull 25" of vacuum and than given a couple of spoonfuls of oil always work better... .

Again, that was a different pump but the same function and design. . Just my thoughts. .

Thanks, when it stops raining, I'll try.

Shadrach is right, I didn't need to remove the pump. The real problem would have been if I didn't have the original belt in the truck. It was raining buckets when I asked and emailed Robin for an over-night delivery of a new pump. I could have got one here by tomorrow, amazing. I installed the belt and all is well, wouldn't want to do that on the freeway with a hot engine.

Thanks guys, and thanks Robin.

I saw them used on the 5. 7L GM diesels before Ford; however, they were camshaft driven from the distributor drive gear instead of a belt.
