Well, the Factory absolutely refuses to sell me a replacement bearing cap even though i've had two highly influential dealerships attempt to acquire one. ONCE AGAIN...the factory has shown it's lack of support or concern for it's customers. As far as their concerned, you can take one of these... :kck: . I am in the process of having the cap welded since there is no other choice. The machinist is very confident that the process should go smoothly. Bigern

I hav'nt seen the cap, so am not sure how complicated it is, but would'nt it be better to get a new one machined out of billet alloy, rarher than risking welding distortion or breakage?

Bigern,
Where is this bearing cap you are looking for and what is it used for? May have a source for you.

The cap in question is used on the transmission output shaft to help clamp down a roller bearing on the end of that same shaft. The cases clamp down on two other roller bearings on the same shaft, but leaves the third bearing half exposed were it intersects the main driveline output gear. That is where the cap comes in. It's about the same size as a Chevy 350 piston rod end cap. If you've got a factory manual handy, look on page 5.5-5.6, there it shows removing the Transmission Output Bearing Cap. It is also shown on the illustrated parts page showing the case halves. It is shown right in between the case halves.
As far as the welding process, The guy is going to bolt it down the the case half and check for any distortions of the inner circumference as the process proceeds. This should help keep everything in line. I had thoughts of having one made out of billet, and still may after the cap is fixed, using that same cap as a templet. It may be my last resort short of buying a new set of cases.
Dave, if you don't have access to a manual, MSG me a fax number and i'll fax you a picture of the offending part. This part is manufactured completely seperate and sent down the assembly line to be matted with a set of cases. True, there may be some trueing up work that may need to be done for a perfect fit, but there is no reason why they can't grab one out of parts bin. Triumph won't even let me have on off a warranty or trainning engine. Thanks for the interest and suggestions of help. As always, the members of this Forum have been a great help!

Big......just a thought, do you have a consumer affairs burea in the US....give them a call and let them know that Triumph wont sell a part listed in the Factory Manual

That's the catch...the part is not listed separately, it is listed with the case halves under a combined part number. In other words, you would have to buy a set of cases to get the cap. This makes no sense to me since the cap is manufactured apart from the cases and latter "fitted" to the cases. And since the cap holds down a caged, ball roller bearing. fittment can be obtain by a seasoned machinist. It's really just a matter of matching the inner diameter of the cap and case bore to the outer diameter of the caged bearing. What's the worst that can happen?, break another cap? There is no chance of damaging the bearing...it's too big, and the cap is too thin. The cap will always give first.

i understand mate....its a technicality part number issue....consumer affairs might approach triumph regarding unfair practice, common sense should prevail

Can you locate on Bike Bandit? If so, I looks like they have some of these parts listed with numbers and costs. Do you have the Triumph Part number?

Dave, when you go to the Bike Bandit site for the R3, the crankcases (pn 5565631-001) is the first to show up. If you look in between the case halves you will see the cap in question. I had one parts guy tell me that the cap shown was a crankshaft hold down cap. Not so...R3 engines do not use seperate caps to hold the crank down, That is what the case halves do. As you can see in the illustration, there is no part number assigned to the cap alone. Triumph considers the cap and case halves as a complete unit under one part number.

So, does this mean if a dealer is doing any of the maintenance you did and this part breaks, they will have to get the complete assembly? Seems a dealer should be able to get this part. Or any part they need. Does a dealer have a specific part number? Does anyone on these boards have friends at Triumph?
