WR400 99 manual owners, need some data

14 posts in this topic

In "mm" please, just correct red data if wrong

1.

manual, page around 4-44 (cylinder and piston)

-cylinder bore "C" = 92.00~92.01 mm

-taper limit "T" = 0.05 mm

-out of round "R" = 0.05 mm

-piston size "P" = 91.945~91.960 mm

2.

next page, or 4-45

-piston to cylinder clearance = 0.040~0.065 mm; Limit 0.1 mm

piston ring side clearance

-top ring = 0.030~0.065 mm; Limit 0,12 mm

-2nd ring = 0.020~0.055; Limit 0.12 mm

3.

page 4-46

ring end gap

-top ring = 0.20~0.35; Limit 0.60 mm

-2nd ring = 0.40~0.55; Limit 0.90 mm

-oil ring 0.20~0.50 mm

4.

page 4-47

piston pin to piston

-piston pin outside diameter = 17.991~18.000

-piston inside diameter = 18.004~18.015

-piston pin to piston clearance = 0.004~0.024; Limit 0.07 mm

30 numbers overall, hope its not too much to ask.

I do have manual, but for past 2000 WR 400&426, so manual pages could differ.

Thanx

Cheers, Denis

Could make it blue, but...

Yes, nice link, only YZ 400's are available, probably data I search is comparable :thumbsup:

Denis,

I added in blue what my manual has for 1999. I only see a few differences, and they are service limits.

Thanks, you've just made my day.

Thankfully, data for YZ 400 '98 has the same diffrences as you've pointed out, so it is OK to use the link from Kepy.
