bearings and seals are over priced

[PeteG40]

either kluber (horrid sticky shit they sell on gladersiete) or spray lube - we sell.. See merchandise!

[tdh-syorks]

is there much differance?

[PeteG40]

kluber is much thicker.. needs applying with a brush... you can only apply it when the charger is apart... the ptfe grease you can apply it either apart or down the inlet hole when running

 Super stuff Tom,
 Many thanks for the info fella. I reckon the specs will be of use to many
 like myself with limited knowledge of the charger. I dare say many have spent hundreds
 of pounds having the likes of Jabbasport rebuild chargers because of fear of doing it
 themselves. Of course, some mechanical knowledge is essential! especially removing &
 and refitting bearings/seals as i`de hate to think that someone may use a screwdriver
 as a drift to knock out the old bearings. I used to do all the machine maintainance at
 various places i`ve worked at so would more often than not machine a press tool
 on a Lathe for the purpose.

 Me thinks that this site needs an archive section for all reference data like this.

 And to Pete, I remember the conversation well when we scrapped the Genisis conversion
 i`de bought. (about the charger)
 It was said by the guy i got it from that it had recently been done but there is no proof
 as such of this.
 I would much rather have it apart and check it over than just use it unsure.
 
 Is it ok to take it apart and if ok then to put it back together and use it? or does this
 contribute to damaging seals ect.
 Many thanks chaps,
                            Fred.

you can sometimes disturb seals, but can only really tell if bearings are worn when they have play... which is sometimes too late!!!

[tdh-syorks]

yeah the bearings i removed were really sloppy, as i'vediscovered last night the hardest part is trying to get the new bearings in, even with heat.
i'm going to try and make another attempt today.

[PeteG40]

oven 120 degrees fro about an hour...

bearings - freezer overnight...

pop... no drifting, straight in.

the key is to prepare the countershaft in the same way (shaft freezer - bearings oven) and then put the whole shaft in the freezer overnight before heating the casing.

[tdh-syorks]

so i should assemble the shaft first then build the casing around it??
sounds awkward but i'll give it a go
oh and how would you go about tidying up the outer casing? would you paint it??
i shot blasted mine last night and it still looks dull and dirty.
if you paint it what paint do i use?

cheers Tom

[PeteG40]

you assemble the counter shaft into one unit with bearings and weight etc. then pop in freezer.  When you heat the casings up you pop the centre bearing and counter shaft in. they just drop in. Easier than bearing, woodruff key, counterweight, bearing and going in the countershaft hole.

I cleaned the external part of mine with petrol as a degreaser and then used hi -temp paint. doesn't need to be ultra hi temp though.

if you need to give me a bell, please do.  Also if cutting apex seals, make sure they are slightly longer and then kindof force them into the hole... so there is absolutely no forwards/backwards movement, or this can wear the apex seal walls.

 Bizzmeknicks,
                   Glad the oven/freezer bit is mentioned or i`de have been worried doing it
                   as well.
                   I did wonder about pressing in the sleeve roller bearing as it seems to
                   have a forged steel casing and so using a press may distaught it.

                   One more thing,  is there a Gasket between the 2 casing halves
                   or is it just Blue Hylomar or something?

[PeteG40]

the roller bearing will simply 'plop' in the centre. If it takes any real force, its not hot enough/cold enough. Be sure to support the bearing housng on the scroll (i.e. dont rest it on the apex seal walls as you might bend these!)  Also the seals on the scroll are often slightly recessed by about 1mm

and its just hylomar.

[tdh-syorks]

built finally. i'm going to fit to the motor tomorrow, see how it goes. the bearings did ned some slight force tho, even tho thy were frozen and heated

[Fred]

 Sounds like a nice tight one then Tom.
 Pulled mine into the house and took some pics
 but i don`t know how to post a pic yet till i suss it.

[tdh-syorks]

just click on the additional options on the bottom left of your reply sheet and browse the image, was a right ball ache putting it back together as i forgot how it went.
i recomend you take lots of photo's whilst you dismantle it, it'll make it easier when you rebuild.
oh yeah mate its really tight, i need to lubricate it before i put it in,
sounds a bit strange that line above lol.
