Evening folks,
I'll start with my favorite thing-cleaning parts. Not!

| Pretty nasty, used oven cleaner to get the baked on stuff loose/ |

| Dirty carb pistons |

| Cam covers after a little cleaning. |
Thought I'd discuss how to refurbish the Lucas Alternator, this one was working fine electrically but spinning the pulley made it squeak so I thought the bearings were dry. The first step is to remove the nut that holds the pulley/fan on the shaft, this is easily accomplished if you have an impact wrench, once the nut is off a gear puller will likely be needed to pull the pulley off the shaft. once the fan is out of the way you can access the heads of the fasteners with a modified screw driver.

| This was a tool I had made to disassemble the case |
 |
| Three 'screws' than have been pinned over at the end |
 |
| The case will come apart pretty easily, watch carefully for spacers and washers that may fall out, this is looking down into the case at the diodes and brushes. Jennifer's brushes had a lot of life left in them so will leave them alone. At the center there is a needle bearing and in this one the bearing was dry with old grease dried around the rim. |
 |
| The armature has to be pressed out of the end of the case, be careful here as the bearing is mounted in the end and this piece seems somewhat fragile. |
 |
| The brushes ride on this piece and I cleaned it with electronic cleaner |
 |
| The parts, at the bottom is the second dry bearing, remove the cover that you can see with one of three screws removed. I chose not to remove the bearing from the carrier as I think it would have damaged the bearing and it can be cleaned easily in situ. |
 |
| Back together, make sure it's 'clocked' correctly, previous pictures help here. |
 |
Hopefully a lot more life left in this little alternator.

Cheers,
Lynn

Ooh, yucky carbs. They look much better after the cleaning.
ReplyDeleteI have never touched an alternator. Looks complicated. What grease did you use? I use Super Lube for almost everything (but I guess it is not for my idler pulley bearing).
I always feel good about the work I've done on my car at the end of the day. Then I come look at your blog and see that you've done a lot more. :-|
Hi Drew,
ReplyDeleteThanks, I noticed that the cold start mechanisms aren't the same from carb to carb so will adjust that today too, hope it runs better but it ran pretty well before so I might have jinxed myself.
The alternator is pretty straight forward mechanically, electrically, well for me at least that's another story. If you decide to dig into one of them you'll just need to take an old common flat tip screw driver and modify it to fit the heads of the fasteners. A press is useful to press out the armature since I think pounding on it could have a detrimental 'impact' on it ;-)
Cheers,
Lynn
