trchris Posted November 8, 2021 Report Share Posted November 8, 2021 Hi Jon Put a drill down the length of it as its brass should be easy then chisel across the top that should brake the seal Chris Quote Link to post Share on other sites
John h Posted November 8, 2021 Author Report Share Posted November 8, 2021 Okay Chris I’ll have a go just wasn’t sure if there was a pin or something to my mind it should just slide off Quote Link to post Share on other sites

As stated the trick is to split the side of the remaining bush along its length with a drill or Dremmel cutting disc and then it should release from the shaft.

I was told the issue stems from the oil holes in the bush not aligning with the oil holes in the gears. Plus when the end float of the 2nd gear gets excessive the rim breaks off the top hat shaped bush. No doubt someone with more knowledge can slam me down or nod in agreement. My preference is the two part steel bush and washer like the Police spec 2.5PI & all Stags used. Moss et al sell as 129939X You cannot break the top hat rim/thrust washer part off as it is not attached to the main bush. https://www.moss-europe.co.uk/bush-2nd-gear-uprated-129939x.html Peter W Peter W Quote Link to post Share on other sites

I ask because my car (with 2000 box) is hard to get into 2nd when cold, but eases considerably when fully warmed up. Ralph Quote Link to post Share on other sites
John h Posted November 9, 2021 Author Report Share Posted November 9, 2021 Hi Ralph vary hard to see because it’s not a clean brake it must have ceased and pulled itself apart Quote Link to post Share on other sites

Ralph Mine box issues started when 2nd acted like it lost synchro (it’s a tr6 box A type od) it later went bang. but I have abused it somewhat before that. Quote Link to post Share on other sites

Ralph Mine is the same, but the "difficulty" can only really be caused by the synchro hub outer's being stiff to dislodge from the neutral position, or the gear selector ball / springs being too "notchy" The gears located on those bushes are spinning all the time & don't move when you engage them, only the outer part of the synchro hub moves. I put my "stiffness" down to it being a gearbox intended to be used with a much longer gear lever than my stubby TR3 one Bob Edited November 9, 2021 by Lebro Quote Link to post Share on other sites
BlueTR3A-5EKT Posted November 9, 2021 Report Share Posted November 9, 2021 My car has a Stag box with the two piece 2nd gear bush. When cold, engaging second is heavy but eases as the whole thing warms up. The gearbox was a new original Triumph Stag box that I had a TR6 input shaft etc. fitted, so it would work in the TR3.

It was a fairly clean break and the bush wasn't siezed. I replaced it with a 1 piece steel version (from ORS). Is there any advantage to the 2 part version?

John h Posted November 9, 2021 Author Report Share Posted November 9, 2021 Hi all got the bush off cut it in the end found out where the broken tooth came from That’s on the magnetic drain plug right down in the bottom of the gearbox on the lay shaft Fortunately a little while ago I bought a tr six box That was dismantled and there is a spare one in there so happy days start to look round for rebuild kit now any suggestions welcome I noticed that the moss second gear Bush is out of stock hopefully they get that in shortly if so i’ll get one thanks for your help and suggestions let you know How I get on regards John Quote Link to post Share on other sites

Lebro Posted November 9, 2021 Report Share Posted November 9, 2021 If you buy the Moss re-build kit it comes with cheap & nasty main ball races, & a lot of bits you won't need (for alternative versions of the box). better to just buy the parts you need, & choose the (much) more expensive ball races.
