Oilite bushes.

New oilite bushes. Am I correct in thinking that they should be soaked in oil overnight before fitting. Somewhere in the back of my mind I think I have read that this is the correct procedure. Please correct me if I am wrong.

John, reading Oilte’s own literature, bushes are “loaded” with oil from new, as a result of reading this I did not soak the Oilite bushes installed on my girling brake levers, which subsequently seized locking the brakes on.
Advice on here has been to soak the bearings prior to use, some say use hot oil, some say soak for 24 hours etc It has also been pointed out that whilst the bushes may have been supplied loaded with oil, we the buyers do not know how they have been stored or how long they have been stored by the supplier, have they “dried” out?? So I soak them.

Hi Both
I understand it is best not to ream oilite bushes as this tends to seal the surface and prevent the oil doing its job! Cheers Howard

Agreed Howard, says that too in the Oilite literature.

Luck I guess, had new brake cams and bushes which were a good fit, certainly no movement between cam and bush and the bushes were a tight fit into the bush housing, used bolt and nut to pull the bush into place.
The Oilite literature warns against using anything other than very sharp tools and refers to the use of diamond tipped tools, certainly no grinding or blunt tools as these will smear the sintered metal and close up the pores which allow the oil to do it’s work.

HI ALL,
Small Sintered Bushes we allways loaded by placing between finger and thumb load with oil and squeeze works every time, you will see oil coming through the bush. no time to wait 24 hours to let them soak. Cheers Colin NZ

I do not intent to ream the bushes but have thought about once the bush has been started in the hole putting the new cam in the bush and pressing/gently driving the bush and cam in together using the cam as a fitting tool.

Pressing them in on a mandrel is the way I do it John.
