TR6 Diff Part 2

[tr6fan]

Right, it managed the trip to the show and now I've got the back end in the air and the diff on my work bench (aka the freezer-don't tell swmbo) I can't find any damage, it seems dentally sound on all cogs. Oil was OK, smelled oily with no unexpected bits in it. The video shows how it turns and what play there is-I hope. Seems smooth when the whole assembly is turned in the same direction. The car was rebuilt completely in 1995 but, although the engine was rebuilt, the notes say for the "running gear" (I assume diff included) "Shot blast and paint black"-could be that it has never been rebuilt, but if it is still OK I'd rather leave it as Triumph set it up-any opinions?

TIA

My opinion is never touch a running system.

It is difficult from a video to check a diff.

Would recommend to invite a clubmate or put the

diff in the trunk and visit him for check.

 

As I heard horrible stories about refurbish of diffs here in the forum

and I am just involved with a TR6 diff repair with bad parts, there

is some fear to refurbish an otherwise long time working item

with parts that let the diff fail soon.

 

Yesterday I spent half a day to correct bearing seats on the pinion.

The bigger seat was too large it was 0.05mm and the small one

was too large by 0.03mm.

It is a pain to fit bearings on that oversize shaft and as I am not

the specialist who does that every day I will have to remove

the bearings several times to re-shim for proper CWP position

and preload. -Wonder if others will do that work in the lathe-

TR6fan, the planets have too much play inem,

onece thrusts wore in, they will become even moer slack,

 

bung some new bigger small thrusts in, { if ye got the fibre thrusts in, scop em away, bung the metal ones in }

needs t,be as TAF whenst re done, as it,ll soon wear to the grooves int carrier,

so it,ll become slack

Andreas, im at a loss as t,what yer trying to say,

 

 

way I read it, your unable to get the Pin pree load right, or Pin depth right, correct,!!

 

If yer havin trouble getting the PIN bearing off { bigg,n }, to fit shim underneath,

then why not wak its bearing race oot, then fit shims under that,

it moves pin upwards into carrier dooing it this way, {same result as fitting shim under Pin heed }

The diametre of the shaft was too large

you could not press the bearings on!
