Crank bearing

[mista_max]

Rebulding the engine and need to repace crank bearings. I'm reading J1 J2 J3 J4 on the crank 2332 and on the case just one number 3. Guess that means 3 for all For all case journals. If i do the calculation i would get 0 for J2 J3 bearings . What color should I use ?

Bearing colours are:

1 - Blue
2 - Black
3 - Brown
4 - Green
5 - Yellow
6 - Pink
7 - Red

See section 3 page 40 of the Service manual.

That you asked the question would imply that either you don't have a service manual. If this is the case then it would be foolhardy to try and re-assemble without one.

Here is the link from Vmax outlaw.

You can get a service manual, and an owners manual there.

Regardless of the numbers for the rods you might consider the Blues for all locations.

Hi,

Silly question perhaps: but how that colour code turn into a spare number? For example blue main bearing, is it 1FK1141601 (first/uppermost option of the list of spare parts suppliers? There is no mention of colour codes). Just want to make sure before ordering anything

I'm going to built a budged engine based on Venture 1300 block & pistons and 1200VMX other HW. Crank need some polishing and I'm I was thinking of ordering your HD oiling kit to increase lubricating performance.

Hi,

Please take a look at the attachment. It shows the bearing types and also calculates the theoretical one you need.

The bearings will have the same part identifier number (11416) and the colours are identified by the number in bold e.g.
BLUE 1FK-11416-01-00
GREEN 1FK-11416-31-00
BROWN 1FK-11416-21-00
BLACK 1FK-11416-11-00
PINK 1FK-11416-51-00
YELLOW 1FK-11416-41-00
RED 1FK-11416-61-00

I have some doubts about plane bearings crankshaft – Yamaha VMax 1200 (1995)
I’am repairing the engine, because the motorcycle had been “in hibernation” for several years.
I did not identify the original crankshaft main bearing.
Marks on the surface of bearings and engine block vanished
I used one micrometer and the measures are 36.97 mm (block) and 37.98 mm (rods).
What is crankshaft main bearing color I have to purchase?
What is the difference (clearence) between the thickest (blue or black) and the others (pink or yellow, i.e) bearings.
Thanks

Are you saying that the markings shown below are missing?

Yes, I do not find any number on the lower crankcase half, left or right side.
And anywhere on the crankcase too.
On the crankweb they are clear: 1(P1) 2(P2) 1(J1) 1(J2) 2(J3) 2(J4).
Whitout this information to select the correct crankshaft main bearings What do I think to do:
# To buy 1FK-11416-01-00 (Blue-kit) ot 1FK-11416-11-00 (black-kit) and adjusts with abrasions

There are 4 forward engine mounts. Can you take a picture of each one? They used different mounts over the years to engrave. You can pre-assemble with different bearings and plastigage it or use a mircometer to measure the clearance. But, there is no chart I know of that says what each thickness is.

IMO that would not be a good idea as you could end up with bearings that are too tight or too loose.

What you need to try and establish what the incremental difference is between the range of bearings.

You could try with two bearings from the middle of the range (e.g. 3 & 4) and assuming one gives the correct clearance on a journal then the difference between that and the other one should give you the answer.
With that information you could then plastigauge the other journals and work out what bearings you need.

Your suggestion seems logical and technically viable. Next week I will talk about it with my techician in engine. Thanks

Plastigage!! giter done!
