Generator Rebuild

JohnPom · Apr 8, 2020

Hi,
I decided to strip down my non-working generator from a FE35 Perkins.
All in pieces now.
Lucas could have used something else besides rivets for the bearing.
Couple of questions.
What size is the bearing?
Is the bearing a very tight fit or just a push fit on the rotor?
The bearing seal, is that just a dust seal or does it help locate the bearing as well?
The rivets are 0.150in. is that right or are they metric?
Can you tap and put dome headed screws in their place, from the inside?

The markings on the outside are:
LUCAS
22259H 1 60
039P2 L1 0 12v

well with the wear that is all I can distinguish.

Ta
John

My Lucas catalog says the bearing should have a 17mm bore, 40mm diameter, 12mm width, "fully enclosed" (metal shield on both sides).

I believe it should be a light press fit onto the shaft, you can probably tap it off with a hammer but use a piece of pipe or something against the inner race when you tap the new one on (so the hammer blows don't go through the balls).

I replaced my rivets with hex head self-tapping screws (on a 22258, not quite the same) and a dab of high temp Loctite; seemed to work fine. Sorry, don't recall the size offhand, but I found something that would cut into the existing hole without needing to drill. Looks like your 22259 would take the same screws, but the Lucas catalog only lists a "sundry parts set" for the rivets.

Sorry, it's been awhile, I don't remember about the seal. ISTR there is a wavy washer that keeps the outer race up against the retaining plate, but don't recall if the felt goes under the wavy washer or inside it. The felt rides against a distance piece on the shaft that is important (and easily lost).
