Featured Rickman Triumph Project

I'm putting my cases together and an having a bit of difficulty in remembering where the various studs go in each case before assembling. It may be I am missing a stud or something like that. This is a 1967 T120R. Is this the correct placement, 2 studs in the primary side case on the aft end, and two studs in the timing side case on the outside for the transmission case. I thought there might have been another stud somewhere and can't quite tell from the parts manual what goes where. Thanks for any help!

 

Thanks. On another forum a member helped me figure this out. It seems the PO of this engine used a stud in place of the #43 bolt (on the parts manual), which is what confused me. So when taking the engine apart I did not have the #43 bolt, but instead 2 of the #4 studs. Now I am wondering if I can go ahead and put it together with the two #4 studs, as it doesn't seem to have any clearance problems. Thanks for your comments!

 

Pressure relief valve - So I was cleaning some of the parts from this engine and took the pressure relief valve apart and found that it was missing the piston, everything else was there but no piston. So I am wondering if anyone knows what would be the consequence of running an engine with the pressure relief valve missing the piston? Thanks if you have an idea!

 

So, whoever rebuilt this missed a very important detail! Thanks for the input!

 

I guess it is then up to whoever the present owner is - to make sure all is ok. Meaning that whatever we buy, we own, and there is no way to know except for taking it all apart. I suppose this is the first rule of working on vintage bikes.

 

Rickman gearing. So I am trying to figure out what size front and rear sprockets to use on my Rickman build. This is a standard Triumph T120 engine, rebuilt. What I've got for front sprockets are an 18 and a 19 tooth. For the rear I've got a 49 and 60 tooth. I'mm planning on using this mainly for trails and fire roads and a bit on the street. I'd appreciate any advice on how to set up this gearing. I'm ok with getting different sprockets - I just have these now. Thanks.

 

This is a cool site - thanks!

 

I'm putting my Primary together now and I noticed on the cover plate (for the final drive) that on the inside of the plate is a tit. Anyone know what this is for and if it has to be oriented in a particular way?

Also, what do folks use to seal this cover plate, I've heard some folks use silicone versus something like yamabond?

Thanks.

 

I wondered if it was part of a casting sprue, but seems like that would have been ground off.
