Lebro Posted April 6, 2019 Report Share Posted April 6, 2019 Yes it does sound like clutch not fully disengaging. The forward gears have synchromesh (TR4 on - only 234&4 for TR2/3), so will help to engage, but reverse not so, & so unless all gears are stationary, it will "crunch" Bob.

Z320 Posted April 6, 2019 Report Share Posted April 6, 2019 When you try to engage reverse, and you do not get it in - are there noises from the gearbox? Quote Link to post Share on other sites
Waldi Posted April 7, 2019 Report Share Posted April 7, 2019 And can you get it in reverse when engine is off? This may need a bit of moving with the car to align the teeth. If so, the shifting mechanism that you worked on is probably ok. If not, I would look at that first. Waldi Quote Link to post Share on other sites
RogerH Posted April 7, 2019 Report Share Posted April 7, 2019 Hi Keith, it does sound as if the clutch is not fully disengaging. Check for play at all the pivots etc. With the clutch slave cylinder piston fully in make sure you have the minimum gap between piston rod and attachment hole on the arm. Are you hooking up the rod tot he central hole on the arm. Is it a TR4 or 4A/5/6. I would use a return spring even though the latter are self adjusting. Roger Quote Link to post Share on other sites
Waldi Posted April 7, 2019 Report Share Posted April 7, 2019 Aha, Roger triggers me: is the slave cylinder installed in the correct position conpared to gearbox and intermediate plate? Waldi Quote Link to post Share on other sites

Waldi that's something I must look at as I should have mentioned the engine I fitted is in a Bristol 401 and had to make up the mounting plates for the slave cylinder y so will check this thanks Quote Link to post Share on other sites
