Dalton clutch weights question.

[Fleecer]

I have 5018 miles on sled and 2900 of those was from last year with just a stage 1 tune . I wasnt very nice to it and never blew a belt. Never blew a belt the year before either when it was stock. I was hoping I had a rare good one but who knows

Based on what you have stated, no doubt you have a good one!

At 5018 miles, you should put new upper gear as preventative maintenance. The inner bushing wears over time, hence you might as well buy 22T. Babbits sells them for like 22 bucks.

I bought one from my Yamaha dealer 2 years ago, he had purchased some 22T gears from a local Cat dealer, it was a 22T with no oil holes and it was cheap, $22-$23. Then last year my buddy needed one for his RTX so we went to a Cat dealer which is 1 mile from his house and the price was much the same, very cheap and with no oil holes.

Have been looking on Babbitt’s for a replacement whereas I have about 4K on mine, and all I can find on Babbitt is a 21 or 24. Wondering what sled make and model will show that 22?

Try cat part# 1702-395, it has oil holes.

1702-491 has oil holes.

I'm thinking about trying some Daltons.
I currently am running stm 60y and they haven't given me any trouble but the initial engagement is really harsh and I don't have the top end I see others have. The harsh engagement is the big issue for me. If I bring RPM up slowly it bangs the belt at about 3800 and the sled lunges. Once moving I can reduce RPM until the sled is barely moving nice and smooth and tach reads 3000. This hard engagement is a PIA going in or out of my trailer or moving ahead a little at a gas station.
It's a 2018 sw137, SM tunes, TP rollers, 60y, stock spring. Turns about 8900 on top.
If Daltons ramps initial engagement is smooth I would get a set and try them. Thanks for any input!

try a softer primary spring first maybe to lower engagement ?

I thought of that but the factory Yamaha spring isn't that strong. Once it's past the clutch snapping in the sled will crawl along at a snail's pace really nice and only 3000rpm. Its like the ramps have a divot from the rollers but don't see anything wrong.

If you look at that stock springs rate,it has an harsh engagement and easy shift rate once going,because of its length,like powder falcon said,give another primary spring a try,one with less start,and same or a tad more on finish. Look on Daltons site,or spring rates,a shorter spring in length may bring engagement lower and still have a rate for finish near stock or maybe a little above,depending on wire dia. and number of coils.

I've been looking at their springs and agree with you guys. Dalton blk/red looks to accomplish what you're saying. Blk/blue seems to be used alot from what I'm reading also. I'll start with a spring change, thanks guys!

Yea,thats where I would start,the blk/blue is a tad to lively for me,but Dalton blk/red looks to be a good compermise.Also the Dalton blk/silver 41-125 kg will also work,and his Dalton Red @40-133kg.
