Are you talking about the upper or lower bearings, or both? Both are designed to be accessible for service, and there is a procedure for doing this. |

Ah, I see...I'm not sure, then. I've never tried replacing such a bearing, only servicing the originals! Sorry! |

I was lucky a few years ago in being able to obtain some original-style bearings from a bearing specialist in Manchester, suitable for the 750, 825 etc. They weren't especially cheap and I bought 10 of them in order to get a bit of discount. Unlike on most ball-race bearings, on the early ones, the inner race separates easily and the balls are held in a little brass-coloured cage. The upper and lower bearings should be of the same type. I can't remember which bearing it is; I usually take the remains of the old bearing and the armature to the shop but you could use a micrometer to get an idea of the shaft diameter, just be sure that the shaft itself isn't worn - not so likely on these. I've found that the bearings are usually OK and can be regreased. However I had a 750 with worn bearings a while ago and I fitted new ones top and bottom. When I'm digging through my spares I'll see if I can send some pictures. Stephen |

The place I got my bearings from originally was Bearing Mart. However, it was some years ago, so I don't know if they still have any that are similar. Here is the link:- CLICK HERE TO GO TO hooverbaby's LINK |

Another place I've dealt with, who are excellent and good value are Arrow Engineering in Salford. A large mower dealership recommended them and I found that the price and quality were very reasonable. CLICK HERE TO GO TO hooverbaby's LINK |

better yet can you post a pic of the bearing? I might be able to assist more. |

Yes Mike, I've done that a few times with bearings that have the metal seals. The ones that Thevacuumman has don't sound original but appear to be of this type. The other sort that is common these days are those with the little rubber seals. They can sometimes be specified instead of the ones with metal seals, may cost a little more but it's easier to remove and replace the seal without damaging it.. When removing the metal seals I usually use a tool with a sharp point, dig in, then prise up to remove. It would then need flattening out carefully if re-used; sometimes I must admit I don't put them back. In theory, at least, a load of dirt can get in and wreck the bearing..but in practice drying out of grease seems to be the main cause of failure. Of course, any really abrasive dust needs to be kept out of the bearings. This procedure can often be used with success to re-lubricate but a rough bearing or one which has collapsed will need changing. I've come across some very cheap and nasty bearings too, which need avoiding...but most are fine when they're new.. If I recollect, the 800 usually has the type of ball bearing with the removable inner race and is the same type top and bottom. There's a little clip, which you remove and a spring and screw underneath to access the top bearing. 700s are different, since the bearing housing is rivetted in position..but you never know if maybe someone's put a 700 or 725 motor on it.. If I get chance sometime I'll have a look for the original-style bearings and send a picture. Stephen |
