TR7 engine

[2F45T4U]

I'm putting a tr7 slant in my dolly 1850. What happens about the flywheel? Which do I use with the standard 1850 box? How do you make them lighter <!--EZCODE EMOTICON START :D --><img src=http://www.ezboard.com/intl/aenglish/im ... /happy.gif ALT=":D"><!--EZCODE EMOTICON END--> <br>

I think it will need to be the TR7 flywheel, as otherwise the starter motor on the TR7 engine won't work.

You can use either...<br>
If you use the TR7 one it will foul on the Dolly end plate retaining bolts. So you have 2 options...<br>
Modify the TR7 end plate so that the clutch slave mounting is removed by sawing it off and welding up the remaining bit of the hole. Your dolly one provides a template. I think the other bell housing bolts all line up.<br>
<br>
Or modify the Dolly end plate to use the recessed countersunk set screws that the TR7 uses. Just need a suitable countsink drill bit and pillar drill. Local machine shop should oblige if you clearly mark up the holes and give them one of your countersunk cross head set screws.<br>
<br>
Method 3:<br>
Just use the dolly end plate and flywheel...<br>
<br>
The ring gear isnt an issue with the dolly starter. Ive used both.<br>
<br>
I wouldnt bother lightening the flywheel if you want a sensible idle....but the 1850 flywheel is slightly lighter and still gives 800rpm.<br>
<br>
I cant really tell the difference between my 2 cars....<br>

If you use the 1850 one you can use the 1850 clutch and you can just use the 1850 starter.<br>
<br>
I think. I haven`t seen my TR7 engine for a while...<!--EZCODE EMOTICON START :rolleyes --><img src=http://www.ezboard.com/intl/aenglish/im ... s/eyes.gif ALT=":rolleyes"><!--EZCODE EMOTICON END-->

You need the right spline count for your gearbox input shaft...The 4 speed TR7 single rail is the same as a later single rail dolly 1850 like Adams. The 5 speeder I'm not so sure....may be the same as sprint or 3 railer...<br>
<br>
The outer clutch cover is the same....<br>

Ooooh can't wait to get it fitted... I've truly had enough of my current engine <!--EZCODE EMOTICON START :( --><img src=http://www.ezboard.com/intl/aenglish/im ... /frown.gif ALT=":("><!--EZCODE EMOTICON END--> <br>

<br>
Whats your TR7 dolly like to drive Jonners? More like a normal 1850 or Sprint? <br>

But you would learn far more in sorting out your current setup. You really arent far away and not much is wrong.<br>
<br>
Just persevere and get what you have running right first.<br>
