Transmission/Installation

[Perro Grande]

Hello Everyone,

I am stoked I just got my transmission back from Baker today,(third gear was slipping), going to install it in the morning, was wondering if you guys had any advice as far as alignment. I have my manual , loctite,etc, just worried about alignment of transmission to primary. Of course its easy to take it out, but installation is far more important and I only want to do this once! Any advice would be greatly appreciated!!

I am sure many will chime in but I can tell you what I was told by bigdogtech1 member on here and knows these bikes. He said put the tranny in and make sure if you had any shims under the tranny line them up first. Then install the tranny and loose bolt the six bolts up to the bottom of the tranny. Then bolt up the inner primary to the front of the engine then to the tranny. Tighten all bolts to the engine and the tranny to torque specs. Once inner primary is tight you should be ready to tighten all 6 bolts on the bottom of the tranny(you are lucky my RB has the oil tank under the tranny and its a pain to get to the bolts inder the tranny. Once you have all bolted up put together clutch and primary chain. This is a very quick and not detailed but maybe a start. I have had my tranny out twice the first time was at 3000 miles and at 14000 miles and this has worked for me on basic installation. Hope this helps a little.

Thanks Phatchopper300
Yes this does help, I was planning on tightening the inner primary first then bolting up tranny last as I figured the "lineup" or alignment was with the inner primary, then of course put clutch/primary chain in last. I figured I could rely on this forum to verify my installation process, thanks for replying, I am so ready to go for a ride as it has been three weeks and I am having withdrawls!!!

Tighten motor plate to engine, then trans to motor plate. Check under the trans to frame mounting points with a feeler gauge, and shim as needed. Do not trust factory shims. I use arbor shims from Grainger, .005 is about as thin as you can go before it becomes like sliding tinfoil under there. Of all the Big Dog's I've ever had completely apart, not a single one was properly shimmed. Poor transmission shimming can cause problems way down the road, like leaks in the primary and trans seals, cracked motor plates, worn bearings, vibration, etc.

And how was it dealing with Baker?

I had baker rebuild my trans. several years ago when main shaft broke, and they were great. I have also call them just for info and were very helpful.

Great advise from Moespeeds I totally agree. :2thumbs:

one thing to possibly add is that when all is said and done, the motorplate should slide on and off fairly easily. If it binds at all, you need to recheck your work

Thanks guys for the advice, Baker was great to work with, it did take three weeks to get it back. They were real patient and courteous because I started calling after two weeks as I was getting a little impatient, apparently my main shaft was out of tolerance/and was sliding around, they replaced a gear, all bearings , seals, shifter rod and forks. Packaged it real well and expressed shipped it at my request. It also comes with a one year warranty. The cost was relatively lower than I thought but the waiting time is the only drawback. James and Scott at Baker are real professional!

Thanks Ramiro. I know are lead times are a little out there right now. But we are really trying to give everyone the best service possible. Enjoy the transmission!

Lee...what is the motorplate? the reason i ask is I will be doing this as soon as I get mine back from Baker also.....as for shims....I only had 1 bolt left holding the trans to the frame...so I have no shims whatsoever....you say go to GRAINGERS Moe????

 

[Moespeeds]

Motor plate, also inner primary. Same thing, the plate that connects the motor to the transmission. Get an assortment of arbor shims from Grainger. A bag of .005", .025", .01" should do it. Gotta check the trans bolt size, but I believe they are 7/16"?

Just an update: Bike is back on the road!!!! Transmission shifts real nice, no more third gear slipping, well worth the three week wait to have that piece of mind. Thanks to the guys that posted advice and Baker (James/Scott) for their solid reputation.

How much did bakerrake u to rebuild the trans?

 

[f-okie]

I just had mine rebuilt, and it's on its way home now. James and Scott are just fantastic. They are great to do business with. :2thumbs::flag:

 

[Brew]

Great news Ramiro, glad that you're back on the road...:2thumbs:

 

[Perro Grande]

Thanks Brew!! Its running so good now looks like I will be able to take a trip down the PCH next week

 

[TCALZ06]

So what is the rebuild from baker costing you guys?
Did either of you have the main shaft replaced or upgraded?

 

[Claymation]

It was arround $800 for me with shipping,mainshaft replaced and some other parts

 

[Brew]

I'm thinking I might be next to have Baker do mine. I've developed a leak on the drive side and gained a hellaous vibration. Think my main bearing might be shot...
