Triumph TR6 - re-fitting gearbox/trans.

Wanted to ask if antone else has had this problem. After replacing clutch fork pin cross drill, replacing throwout bearing, pressure plate and clutch disk I was ready to re-install gearbox. Line up the disk with tool and touqued down the pressure plate bolts. My son and I had a hell of a time getting the thing back in. The end of the shaft just would not go into the spigot/motor bush We raised/lowered the motor started with the bolts at the top just would not go in. Finally started with some bolts that were a little longer then the normal on the bottom, drew it in a little, then lowered the motor wiggled and wwith a clunk it slide in What do you guys think the problem was What damage do you think might have occured (Really do'nt want to take it out Did not have a lot of pressure from the bolts before it slide in Thanks Dave

Transmission shaft finally lined up with the pilot bearing? Maybe more of a right-left problem than an up-down problem. Using the bolts helped to line things up.

I have not always had the greatest success with those alignment tools. What I do is torque down the pressure plate until the disk will not move by itself but can be moved with a little pressure. Then line up the disk with the tool and fit the transmission to the engine. The clutch disk will be able to move if it is slightly off center. Carefully pull the tranmission straight back and then fully torque the clutch. Kind of a hassle but in the long run it can save a lot of frustration.
I have seen the fingers bent on the pressure plate (not on a TR6) when forced in, but if yours didn't require much force you should be OK.

Two things: I had a friend help last time I had the tranny out, I was on the passenger side, and he on the driver's side. Problem was, I didn't see that the lever on the end of the cross shaft had been bounced, which slid the TO bearing forward enough to go sideways, and jammed everything about 1 inch from going on. Problem was apparent when we pulled the tranny back out. Next, by using the longer bolts, you happened upon advice given quite some time ago: Use 2 bolts, 4 inches long up on top of the block, with the heads cut off to 'slide' the tranny in on. Helps locate everything, takes weight off the input shaft, etc. Cut slots in the end of those bolts to use a screwdriver gettin' em in and out.


PS....the guy helping me was the same one that last year installed my cross-shaft according to the Bentley manual. Correct for a right hand drive car, and discovered as we were mating the tranny to the engine. I took one look at it and said "WAIT"!! Glad it was discovered before all was bolted down........

I had the equal of a problem putting the trans in. Turned out I lost track of equipment and had already installed the starter after a rebuild. Could not figure why it wouldn't mate on the passenger side. After about an hour I relized the starter was on and the bolt heads were in the way. I'm glad I was alone and was only humiliated to myself, but I am used to that.
