bearing drifts?

[servetakid]

Hi,

Can anyone recomend a set of drifts for doing a lambretta engine?

Or would something like this be any good?

Looks like it would be if any of the drifts matched any of the bearings, I don't have any to hand to check

I think from memory the magneto seals are 46 and 52 mm, so I think the bearing will be 52mm OD

The drive side seal is 50mm OD and the bearing is 62mm.

I think there isn't one small enough there for front wheel or cluster bearing either.

Probably better off looking for a specific lambretta set Madspeed do them on ebay from time to time.

Personally I use an appropriate sized socket and never had much trouble doing so.

get a plumbing torch on any baring and it will push out once the alloy has expanded around it. you shouldnt have to drift any baring out, certainly you should never drift a baring in. always building engines and never force anything,theres a reason if it doesnt fit.

I use this tool myself, it can be used for most bearings on a Lambretta casing.

Used in conjunction with a bit of heat and various sized washers and / or old bearings it's mastered every job I've tried so far.
It's not cheap but it's cheaper than one visit to a "professional" to fit or remove a bearing and it'll last you a lifetime. Along with a £4 spring puller it's about the best tool I've ever bought. Personally I'd never use a drift to fit or remove bearings, I'm too unlucky not to have a major mishap using one.

Having said use a socket I did my mag bearing yesterday, put the bearing on the top of the hole and heated the outside with a blow torch. After about a minute heating it round evenly the bearing just dropped right in!

On using pullers, isn't there more of a risk of pulling it right thru? Tapping it in gently at least you can hear when the sound changes that it's home.
