Default Camshaft replacement questions

Hello all! I am getting a new cam soon and had a few questions. My timing belt was just changed recently and I don’t wanna replace it when doing the cam. Can I just chalk the position of belt and pulley, pull the belt off then put it back on following install of cam? Also, if I install a BEW cam instead of BRM, do I use different bearings? Thank you!

No.

You must use standard lock down procedure and re-time the engine.

The cam sprocket turns independently of the cam hub underneath it, so putting a mark on that isn't really going to help you. When you set the belt tension, the three bolts holding the sprocket to the hub will be loose, so it turns independently of the cam & hub.

In order to get your chalk mark in the right place, you would have to put the sprocket on turned a little bit clockwise from where it needs to end up, and then hope it moves back to the right spot once you apply tension. Also hope the crank doesn't move while you're doing this.

It's just not worth it and is prone to failure. The locking tools are on ebay for $15.

Edit: Just saw your new message. Yes, you can take the belt off and put it back on with the proper locking tools. If the belt, rollers, tensioner, and waterpump are still within their service life (or fairly new) there's no reason you can't just continue using them. By not replacing the belt, you also don't have to remove the motor mount.

Probably goes without saying, but I'll say it anyways... you'll want to be sure to order new lifters with your new cam.

Correct.
As has been mentioned, replacing the cam seems not too difficult. But parts and procedure are critical.

By the way, since you're replacing the cam, I assume you're going to have to remove the hub from the cam. Just be aware that it doesn't come off easily. I've used a hydraulic press to do it.

This is the proper tool for pulling the hub off:

Thank you guys for all the help! So what are the tools I must have? Was reading on some other posts that you don’t have to buy the puller tool and other tools so what are the tools I must have?

For sure need both locking tools. Also the cam counter hold tool is essential. To get the cam hub off I just loosened the bolt then hit it with a punch with the cam still bolted down, can’t off pretty easy actually.

Alright thank you! And what 2 locking tools specifically? Do you have the part numbers?

Dalon, if you are working with me. I can provide everything you need, loaner tools. Information, directions, all the technical support. All you have to do is ask. The bearings are the same.

Also, there are tools you can sink money into, but a 5 lb hammer and a 1/4" punch knocks the cam pulley off. If you budget it tight, save that spent money for a good cam.

I used these ones. Then just resold them after I was done. Much higher quality than ebay stuff.

If you're working with Frank on this, you won't get better advice for that particular job.
