Balancing a 4LO crank
Balancing a 4LO crank
Heard that Mongoose Machining in Vancouver Canada can do the a/n'd - is there anyone else in Canada that is reputable? I know that are good machine shops States side but the exchange is a killer currently. Also can a 4LO crank be welded or is that an RZ thing. I know a RZ crank is better but have budgeted for other 4LO bits for a build.

Went to the CVtech website for rebuilds and only and years 1981-1982 are not on the list unfortunately unless the RD400 is the same crank - don't believe so.

Re: Balancing a 4LO crank
Okotoks, Alberta. Joe Hasloh at RPM has gone over a number of my LC and RZ cranks. I have had zero issues with them and they ran well. Good guy and less distance shipping. 403-995-9583. Those crank pins can also be welded from what I remember. One of my prior cranks had come apart slightly and it was fixed and welded.

Erm ... speaking from personally experienced unpleasantness:
Don't give over ...Anything... you care about to the Bunglers at Mongoose.

Re: Balancing a 4LO crank
Bare is there someone in BC other than Mongoose or do I head east to Alberta? I thought there would be someone in the LMD or the Island that could be trusted to do a decent job.

I send to SCR racing in Los Angeles... and take the shippings as part of the cost of not having wrecked parts
Apparently there are a couple of lower mainland people who do Fine work.
Frankly I haven't used / don't know them.
Try asking at Cypress moto service in Delta. They are up on decent /capable machinists

I have two cranks rebuilt by CVTech. They seem fine to me.Zedixe13 wrote:In Quebec the big place is

I don't know how the 81-82 LC crank is or is not different from earlier or later models but CVTech rebuilt two LC cranks for me so they clearly can do it.LC Cnd wrote:Went to the CVtech website for rebuilds and only and years 1981-1982 are not on the list unfortunately unless the RD400 is the same crank - don't believe so.

Re: Balancing a 4LO crank
Hooli what was the cost on you crank refurb balance n' welding? Just a ball park figure would be fine - cheers.
Re: Balancing a 4LO crank
Mine weren't welded. Price was ca $600 for full rebuild. Seems you can't get a crank for much less these days.

Re: Balancing a 4LO crank
At a $600 rebuild cost you need to start considering a new crank as an easier option https://www.ebay.ca/itm/Yamaha-RD-350-L ... :0&vxp=mtr" onclick="window.open(this.href);return false;
Re: Balancing a 4LO crank
Thats $640 cdn plus $100 shipping plus GST & duties and that ends up being quite a lot more money, closer to $800 cdn. IIRC I only paid around $600 back to my door. It was a while back so I don't remember exact numbers but it wasn't that much over $600.silverstrom wrote:At a $600 rebuild cost you need to start considering a new crank as an easier option https://www.ebay.ca/itm/Yamaha-RD-350-L ... :0&vxp=mtr" onclick="window.open(this.href);return false;

Re: Balancing a 4LO crank
I'm assuming the rebuild included balancing for approximately $600 CND.

Re: Balancing a 4LO crank
The problem with rebuilding 35 year old cranks is your builder may find surprises. For example, if your rebuilder finds a damaged web you may be into it for a lot more than $600. If new is available for a comparable cost, it is an option worth considering. Saving a little money can often cost you a lot more.
