Sanding diff plates - what grade of wet / dry
Hi,
Giving my Cat SX a bit of an overhaul in the coming week and planning on doing a full diff rebuild and wanted to know what wet and dry to use with the Schumacher Cat SX plates. 800? |
start with 600 or 800 then finish with 1200 - 1600 to polish it back up

Any particular tips or just follow Lee Martin's guide in the Tamiya section? I have seen diff plate holding tools, are they worth it? Much More I think |
just use a old diff half to hold the diff plate i try to use a sheet of glass to sand on as well, or a mega flat surface

Is it worth trying to sand / revive existing diff plates, or do you only really do the sanding on new plates?
|
Can keep re-sanding if you wish, no issues. 600grit is your best bet. Personally I wouldn't advise going any finer than that.
|
I do 3 different grades,800,1200,2000,
seems to work out ok:thumbsup: |
Where is the best place to get these grades as b&q are crap
|
I usually get them from a local car spares/accessories type shop. Failing that, Halfords - although usually more expensive.

Halfords, or a motor spares shop. You only really need 600grit, the objective is to flatten the diff rings and give the diff balls more grip, resulting in less slip. |
1000 and 2000 for me

May head back later to have a look. |

Yes.
As Terry said, you're just looking to flatten them. 600g is fine enough to get a decent finish that doesn't feel rough to the ball, but also rough enough to actually "grip" the ball. |

ghost rc balls also turned up :) |
I recently did a over hall myself and i used 600# to remove a built up layer of crud, and the diffs are super smooth again.. I couldnt believe how thick the schey diff rings were compared to other brands ive used..
|
I use #1000 grit with ceramic balls and it works beautifully.
I build my diffs as per this guide and they have never been better:- http://www.youtube.com/watch?v=YOMu6...eature=related Most important don't polish to a gloss shine the balls need something to grip... I also always replace the diff plates in a rebuild. |
