Installing Camshaft/aux Shaft Bearings

[corolln]

hey guys,

 

another problems.. I'm biulding up my 2tg (first engine build) I'm installing the aux shaft bearings, i know that are number etc.

 

do you put them on the shaft and get them in that way casue thats not working the bearing isnt tight enough on the shaft to tight to get into its position in the block..

 

hope that makes sense.. any help will be great

 

 

cheers,

Ah no... you make a special drift that has camshaft diameter to start with, then a square shoulder to take it out to the cam bearing outer diam. (about 2-3mm)

 

You put a bearing on the drift in front of the shoulder & you gently drift it into place with light hammer taps. Cam bearings are very delicate.

 

I'm not familiar with the 2T, but if they are different diameters you will need a drift for each.

 

Which is why some motors I take to the engineer's to get some jobs done!

ok cheers mate yeah there all different sizes inner and outer.. buy a drift? is that just like a gig of some sort??

 

one of the new bearing has light damage marks on the inside use it or buy the bearings?

 

thanks

If its only one groove across the bearing surface it won't matter. It will help hold in in there! :lol:

 

I'm not sure if you can buy 'sized' drifts, I suppose you can. I usually find something the right size or get it spun down on a lathe.

 

Aha! Google has this-
