After about three hours of work the job is complete. Here's a breakdown of how we fixed it.
The hardest part by a mile was the removal of the broken bolt inside the cam shaft. The Service Manager at Land Rover shared a youtube link that laid out of recommendations on how to remove it. Here is the link:
I ended up having to buy a few tools that I didn't have. The most important of which was a 90 degree drill attachment, as the space in the engine bay was extremely limited. We actually ended up removing the air filter housing to make a little more room.
But even with the air filter housing removed, there wasn't enough room to get a standard size drill perpendicular to the bolt. This was the
drill attachment that I bought. It was only $19, and the job would have been so much harder without it. I also bought a
hinge drill bit set for $8.99 and a set of
left handed drill bits for $8.49. I didn't know about left handed drill bits before this project, they are pretty interesting. Here's a
brief description on itstillruns.com
Even with these additional tools it was a bear of a removal. In a moment of weakness I even drove the car down to the garage on the corner to see if the mechanic could help me remove the bolt. He told me he would have to remove the whole cam shaft from the engine, I would have to leave the car for several days, and he couldn't begin to give me a price. I wasn't into any of those three points so I brought the car home to continue the struggle.
The shaft of the bolt was extremely hard metal, and the visibility into the hole was terrible, but in the end the best method turned out to be drilling a few small holes into the shaft that let the left handed drill bits move rotate the bolt by degrees, little by little until I could grip it with my hand. Once it was out the rebuild took no time at all, and the brakes work perfectly now. While things were undone I did an air and oil filter change and an oil change.
All in all I spent $185.56 on the replacement pump and $36.48 on the additional tools, so just under $225 total. Plus a lot of swearing. That helped a lot.
