shadetree 5,973 Posted July 13, 2021 building this for my neighbor 3 doors down, he's been asking all the time for a cheap 4x4 atv, so here i am, restoring a 1991 trx300fw. so far, case half is busted out where the pinion needle bearing sat. ring gear and pinion gear have some bad teeth on them, not sure i want to run them ?. big pinion bearing is shot, nothing but outer race still in diff case. here is some quick pics i just took. 6 Share this post Link to post Share on other sites

jeepwm69 7,750 Posted July 14, 2021 I'd try to reuse those gears if the teeth aren't missing/completely ruined. Maybe file down the harsh spots. Reason being good gear sets are hard as ! to find now. I've been watching for a set of Caltric gears for awhile now and they've been out of stock forever. Caltric usually sells crap, but their ring and pinion gears are good (bearings, not so much). Armor Tech is the only other pressed in ring gear, and they're $$$. 3 Share this post Link to post Share on other sites

Armor Tech is the only other pressed in ring gear, and they're $$$. already one step ahead of ya, will do what you say, file/grind down the rough spots on ring gear and pinion gear, i'm gonna re-use it. i will replace all bearings and seals though with new, after market. this guy is about 75-80 yrs old ?, has a farm near here, i doubt he'll be jumping his cows with it ?..lol. i'll do my very best to make it look good, run good, and stop. i already told him this was a budget build, he was ok with this. his main concern was, he wanted it to be 4x4. so i got this from cat fish, gonna sell it to this guy no more than 2k, and he said this was very fair. 3 Share this post Link to post Share on other sites

shadetree 5,973 Posted July 14, 2021 i went to my buds place this morning ( cat fish ) , picked up some '' replacement '' parts, i am pretty sure i can get this rear end all back together, and it drive ?..lol. nothing will be new on the rear diff cept bearings and seals, and even those are after market, this is a budget build, and we are trying to get the dollar spending down as low as we can, and still have a dependable trx300fw. i did buy a brand new oem c.d.i. for this, out of my own pocket, cat fish wanted a china one, i said heck no..i'm not putting a china c.d.i. on this. i will keep updating as i go. prob be slow on pic's ?, but ya'll will live !..lol. 4 Share this post Link to post Share on other sites
shadetree 5,973 Posted July 14, 2021 i got the rear diff case halves cleaned up, rear axle cleaned up, here is some b4 and after pics of the diff case halves. now i wait on the bearings and seals. 3 Share this post Link to post Share on other sites
shadetree 5,973 Posted July 15, 2021 did anyone notice the red c.d.i. box in my first post pic ?, i pulled that off another trx300 that was out at cat fishes place, it has a sticker on the side of it, it say's '' made in Argentina '' . i know we have had a few talks about some of the trx300's came from the factory with red c.d.i.'s in the past, and some claim that these are factory oem c.d.i,'s, and of course, i always said no, they are china made, so my question is, sense when does honda use parts from Argentina ????..lol. 1 Share this post Link to post Share on other sites

shadetree 5,973 Posted July 15, 2021 well, good news !. i did get fire on plug, i made a trip to cat fishes bone yard, grabbed a couple wire harness, both had the switch housing on them. grabbed a spark plug coil, and a reg/rec. changed out the reg/rec, changed out the switch on bars, changed out the spark plug coil, by hand, i seen spark !. shot some starting fluid straight into the head, spark plug in, a quick kick, she lives !!. now to narrow it down as to which of these parts were the bad part ?. as i changed 3 parts, i will go back , and swap each one back in as is, and see which one changes back to no spark ?. my money say's it was the reg/rec. i'll post results before long. 4 Share this post Link to post Share on other sites
shadetree 5,973 Posted July 16, 2021 it was the bar switch !. here is the carb all cleaned up, few pic's. 7 Share this post Link to post Share on other sites
Fishfiles 20,147 Posted July 16, 2021 Here is a wild stab at a theory for you , that VE91BA carb is really a 95 carb not a 91 , I believe the fuel enrichment plunger for a 95 was the long version where the 91 should have been the short version , someone along the way changed the carb and then changed the kill switch assembly to make the plunger work as the short plunger used a different cable and kill switch assembly , and when they did the kill switch didn't work 1 Share this post Link to post Share on other sites
