I am installing the 686 kit on My Wife's Raptor. The DS can be locked in at TDC which makes it easier to get the jug over the piston.

What way are you guys doing it? Raptortranny.com says to lower the piston to bdc and do it there but. . . man. . . that gives no room for my manly fingers to work (wish I hadn't cut my fingernails last night too - now those rings are going to be a bear!

Also, did you guys change out the orange o-ring at the base of the cylinder when you pulled your jug?

How about the copper washers on the oil lines?

Thanks, hopefully the build will be done by this weekend!

Anyone want to volunteer their phone number for on-call advise for the weekend? Send me a PM!

 

You can use two peices of 2x4 under the piston to keep it a little higher.

Yes I changed the o-ring the first time.

I didn't change the copper crush gaskets, but its probably a good idea, however I have never had trouble with those leaking.

Check your PMs.

 

I had someone hold the cylinder while I worked the piston up into the cylinder. A small slot screwdriver is a great help in getting the rings into the cylinder.

I replaced both the o-ring and the crush gaskets.

Let us know if you have any more questions.

replace all those gaskets
a large hose clamp will hold the rings in the grooves while you tap cyl down

 

Its pretty easy if you have two people and put a bunch of towels and rags under the piston to hold it steady (and keep stuff from falling down the hole).

 

Definitely dont over tighten the oil lines if you didnt buy new copper washers to compensate, the bolt wont strip it will break the case or head first. If they leak take em off and replace em.

 

Thanks for the info guys. I'll try to re-use them and see if I can't pick some up at the local dealer.

Anyone have exhaust bolts crack on them? A buddy with a 2001 (Original Tranny) was putting on an aftermarket pipe and had the bolts break on him. I ordered a new set (only about $1.5 each so cheap insurance.)

Thanks for all the info. I can't wait to get this thing together and running.

 

I would Pm sixsixt for info,he built mine and it started the first time i pushed the start button...

 

Ring compressor helps a lot, or just a big hose clamp like someone else mentioned.

 

That is the show nuf truth!!! I broke mine and had it welded back for the Nationals, it still leaks.[img]i/expressions/face-icon-small-mad.gif[/img]
