oil seals and bearings ??

[Richard Thompson]

Ive a clam shell engine open for a new piston rings and seals, would you change the bearings as well as the seals just because it's open or just the seals and save a few quid for the customer?

The client said just fix the saw and I'm waiting for the parts anyway so adding the bearings wont hold up the job.

Is it ethical or economical to change and strip the bearings or do the job again in 18 months

 

If I change a cam belt I normally change the water pump just because it's convenient and cost effective whilst the cars off the road and the engines open

 

What's your opinion please

Give the customer your opinion then let them decide

I would normally check the bearings and only replace them if they had signs of wear or the machine had been run after seizure dumping aluminium powder on the bearings.

What machine is this? many Husqvarna clam shell engines incorporate the seal around the bearing, once compressed and removed they do not sit very well if re used, so would normally replace them.

Its a husky 450e with the plastic bottom half and the bearings sound fine when spun with no unwanted movement in any way, it's a five year old saw that has not seen masses of use but has been slightly abused by one or two semi half wits.

 

I think i'll tell him the bearings are fine but not to lend out the saw and look after it, the old seals let air out when i tested the comp with a drop of soapy water around them and when i stripped the engine one slid off the shaft and stuck to the lower case and the other slides back and forth easliy
