Title: Dolmar 123 worm gear/part saw
Post by: 604f_1 on December 22, 2014, 04:53:04 pm
Hello everyone ! I'm building a dolmar 123 hotsaw but the worm gear is totally toasted . If any of you have one and could part of it would be awesome ! I'm also willing to buy a part saw or even a good running one !

 Thank you in advance ,Luc

from what i saw the worm gear and piston come as a set. no separate part number for just the worm gear. get me an email and i will send you the ipl. wont do too much good as most parts for that are obsolete but will make hunting for nos parts a bit easier.

The kit I have is PN 957 245 320.  Don't know what it fits.  If it does work JJ has 1st dibs on it.

That part number is for the old style 116Si/120Si with the steel worm and full time oiler.

The newer 116Si/120Si had a plastic worm and a part time oiler driven by the clutch bell.

This is for the straight 123 and 133. The 133S is different

The two oil pump gears for the 123/133 is #133 245 030 the gear that is on the oil pump side is made onto the pump piston -  this is for 9/81 and later

The oil pump repair kit for the 123/133 is #957 245 310  This is for 8/84 and later

The complete new style oil pump including the steel worm that goes on the crankshaft is #133 245 310

Did you call Scott and tell him what you are looking for?  oil pump drive gear for Dolmar 123 or 133?  The 123 and 133 are the same except for the bore.

He has a lot of saws that have not been disassembled. He usually works on the better movers.

I'm sorry the numbers have a different prefix. I spoke out of turn
Item 0    #133 245 310 is the oil pump and the gears
Item 1    #957 245 310 is the little parts for the pump no gears
Item 2   #133 245 030 is the two worm and pinion gears
