720Phil Posted April 30, 2013 Report Share Posted April 30, 2013 Looking for Ring and Pinion or complete 3rd member for a 81' KC 4x4. H190A with 4.375:1 ratio. Thanks, Phil 3 Link to comment
datzenmike Posted April 30, 2013 Report Share Posted April 30, 2013 I have found that early 4x4s used the same driveshaft yoke as all 2wds, so the diff will swap. Sometime in or around '82/'83 the 4x4 driveshaft/diff yokes became bigger, and NO you can't merely swap the diff yoke to a 4x4 because the internal spline is different also, I tried that. If you look carefully, '80 (L20B motors) 2wd automatics were mostly 4.375 and should fit your 4x4. This gives you a few more options. If you are wrecking yard searching the diff ratio is stamped on the engine plate under the pass side hood hinge on the inner fender. Look for HF43 (43 is 4.375) Link to comment
720Phil Posted May 2, 2013 Author Report Share Posted May 2, 2013 Hmmmmmmmmmm. Just looked under my hood at the codes. Never mind I have removed my Diff and counted the ring and pinion and did the math to come up with the 4.375. I had a friend help me and he is an off-road guy, and we both counted the same thing. The VIN says I should have a 4.375. My tag says FS5W718 HE38! The reason this disturbs me is now I wonder whats in the front Diff? Any guess? Phil Link to comment
Sealik Posted May 2, 2013 Report Share Posted May 2, 2013 HE38??? I have some 4x4s with 4.38s.....but....shipping alone might be more than you're willing to pay EDIT You sure that is the correct tag displaying HE38? Link to comment
720Phil Posted May 2, 2013 Author Report Share Posted May 2, 2013 Anybody know what HE38 means? Link to comment
datzenmike Posted May 2, 2013 Report Share Posted May 2, 2013 KMY720................................ The K makes it a King Cab, M makes it a Z22 ,Y makes it a 4x4 JN6MDO6YXBW-16965......... The 10th descriptor B makes it an '81 model year. HE38 is an H-190 3.889 diff. Never seen a 3.889 in a 4x4. I've seen it listed in a vague manner but thought it was a misprint. The rear end has obviously been changed. The front ratio is unknown but in mud or loose/soft surface it would spin faster than the back and you wouldn't notice much. On pavement you would.

720Phil Posted May 3, 2013 Author Report Share Posted May 3, 2013 Checked the front last night (the old mark it and spin it routine) and the drive shaft was just about to complete its 4th revolution when the mark on the on the left flange made its 1st revolution. So a 3.889 it is! So does that make this easier or impossible? Phil Link to comment
720Phil Posted May 3, 2013 Author Report Share Posted May 3, 2013 I will check the diameter and count the splines. Will that help? Link to comment
datzenmike Posted May 3, 2013 Report Share Posted May 3, 2013 May be easier to get a matching front and back 4.375s Link to comment
720Phil Posted May 7, 2013 Author Report Share Posted May 7, 2013 OK, OldHillBilly has sent me the info from tag from under the hood. Can anyone decipher it? Tag reads as follows: DATSUN type - KHY720, Engine Capacity - 1952cc, Max HP/ RPM - 92/ 5200RPM(sae), Wheel Base - 2815mm, Engine Type - L20B, Chassis Number - KHY720-********, Nissan Motor Co., LTD, Yokohama Japan 44W11. Tag apparently does not say list Transmission or Trans axle directly. Phil Link to comment
datzenmike Posted May 7, 2013 Report Share Posted May 7, 2013 Sounds like an '80 King Cab 4x4. This will have 4.375 diff. Link to comment
